Overview of Fiber Optic Cable Specifications

Many questions tell us that it is important to protect the fibers.But how to protect the fiber cables,the first one is to know the fiber optic cable specifications,when we know it,we can protect it best. Cable’s job is to protect the fibers from the hazards encountered in an installation. Will the cables be exposed to chemicals or have to withstand a wide temperature range? What about being gnawed on by a woodchuck or prairie dog? Inside buildings, cables don’t have to be so strong to protect the fibers, but they have to meet all fire code provisions. Outside the building, it depends on whether the cable is buried directly, pulled in conduit, strung aerially or whatever.

Since the plan will call for a certain number of fibers, consider adding spare fibers to the cable – Cost of fiber optic cable is cheap! That way, you won’t be in trouble if you break a fiber or two when splicing, breaking-out or terminating fibers. And request the end user consider their future expansion needs. Most users install lots more fibers than needed, especially adding single mode duplex fiber to multimode duplex fiber optic cable for campus or backbone applications.Now, let’s go to know the standard fiber optic cable.

A standard fiber optic cable is comprised of four specific parts:

Core – A fiber optic’s center is made of glass, and this tube carries the cable’s light signals. Depending on the type of fiber optic cable (single mode or multi mode), the core varies in size. Single mode duplex fiber consist of a tiny glass core that typically has a diameter between 8.3 and 10 microns. This type of cable is usually installed for transferring high speed data over long distances. For multi mode fibers, the core is larger. Their core size ranges from 5 to 7 times larger than single mode cores. With a diameter ranging between 50 to 62.5 microns, multimode duplex fiber optic cable is perfect for high data applications. Multi mode cables are typically used over shorter distances than single mode fiber optic cables.FiberStore provide the hot seller multimode cable–OM4 multimode fiber and OM3 multimode fiber.

Cladding layer – Also constructed of glass, this “core cover” is used to keep the light in the core. When transmitting data (especially over long distances), light rays can reflect off each other and travel in different directions. The cladding keeps those signals straight.

Buffer – Also called the buffer coating, this sleeve protects the core and cladding from foreign material (FM) such as outside light, moisture, dirt and other substances. More often than not, the buffer is made of plastic.

Jacket – The fiber optic’s cable exterior is typically made of tough, durable polyurethane. Its job is to protect the overall integrity of the fiber optic cable. The jacket is the first line of defense in a fiber optic cable. Routing cables can put stresses on a fiber optic cable (kinks, knots, etc.) and a jacket sometimes contains an extra layer to avoid these potential hazards.

Fiber Optic Cable Based on Fiber Types

Based upon fiber types in a cable, fiber optic cables can be categorized as three types.

Single Mode Fiber Optic Cable
All fibers in the cable are single mode fibers.

Multimode Fiber Optic Cable – Multi Mode Fiber Optic Cable
All fibers in the cable are multimode cables.

Hybrid Composite Cable
Both single mode and multimode fibers are packaged in one cable, such as 4 multimode fibers and 4 single mode fibers in a single cable.

How Many Fiber Connector Types Do You Know?

Different Single Mode and Multimode Fiber Types

Fiber optic cables are the medium of choice in telecommunications infrastructure, enabling the transmission of high-speed voice, video, and data traffic in enterprise and service provider networks. Depending on the type of application and the reach to be achieved, various types of fiber may be considered and deployed, such as single mode fiber type and multimode duplex fiber.

Fiber optic cables come in several different configurations, each ideally suited to a different use or application. Early fiber designs that are still used today include single mode fiber type and multimode fiber. Since Bell Laboratories invented the concept of application-specific fibers in the mid-1990s, fiber designs for specific network applications have been introduced. These new fiber designs – used primarily for the transmission of communication signals – include Non-Zero Dispersion Fiber (NZDF), Zero Water Peak Fiber (ZWPF), 10-Gbps laser optimized multimode fiber, and fibers designed specifically for submarine applications. Specialty fiber designs, such as dispersion compensating fibers and erbium doped fibers, perform functions that complement the transmission fibers. The differences among the different transmission fiber types result in variations in the range and the number of different wavelengths or channels at which the light is transmitted or received, the distances those signals can travel without being regenerated or amplified, and the speeds at which those signals can travel.

There are two different types of fiber optic cable: multimode and single mode fiber type (MMF and SMF). Both are used in a broad range of telecommunications and data networking applications. These fiber types have dominated the commercial fiber market since the 1970’s. The distinguishing difference, and the basis for the naming of the fibers, is in the number of modes allowed to propagate in the core of a fiber. The “mode” is an allowable path for the light to travel down a fiber. A multimode fiber allows many light propagation paths, while a single mode fiber allows only one light path.

In multimode fiber, the time it takes for light to travel through a fiber is different for each mode resulting in a spreading of the pulse at the output of the fiber referred to as intermodal dispersion. The difference in the time delay between the modes is called Differential Mode Delay (DMD). Intermodal dispersion limits multimode fiber bandwidth. This is significant because a fiber’s bandwidth determines its information carrying capacity, i.e., how far a transmission system can operate at a specified bit error rate.

The optical fiber guides the light launched into the fiber core (Figure 1). The cladding is a layer of material that surrounds the core. The cladding is designed so that the light launched into the core is contained in the core. When the light launched into the core strikes the cladding, the light is reflected from the core-to-cladding interface. The condition of total internal reflection (when all of the light launched into the core remains in the core) is a function of both the angle at which the light strikes the core-to-cladding interface and the index of refraction of the materials. The index of refraction (n) is a dimensionless number that characterizes the speed of light in a specific media relative to the speed of light in a vacuum. To confine light within the core of an optical fiber, the index of refraction for the cladding (n1) must be less than the index of refraction for the core (n2).

Fibers are classified in part by their core and cladding dimensions. Single mode duplex fiber have a much smaller core diameter than multimode duplex fiber optic cable. However, the Mode Field Diameter (MFD) rather than the core diameter is used in single mode fiber specifications. The MFD describes the distribution of the optical power in the fiber by providing an “equivalent” diameter, sometimes referred to as the spot size. The MFD is always larger than the core diameter with nominal values ranging between 8-10 microns, while single mode fiber core diameters are approximately 8 microns or less. Unlike single mode fiber type, multimode fiber is usually referred to by its core and cladding diameters. For example, fiber with a core of 62.5 microns and a cladding diameter of 125 microns is referred to as a 62.5/125 micron fiber. Popular multimode product offerings have core diameters of 50 microns or 62.5 microns with a cladding diameter of 125 microns. Single mode fibers also have 125 micron cladding diameters.

A single mode fiber, having a single propagation mode and therefore no intermodal dispersion, has higher bandwidth than multimode fiber. This allows for higher data rates over much longer distances than achievable with multimode fiber. Consequently, long haul telecommunications applications only use single mode fiber type, and it is deployed in nearly all metropolitan and regional configurations. Long distance carriers, local Bells, and government agencies transmit traffic over single mode fiber laid beneath city streets, under rural cornfields, and strung from telephone poles. Although single mode duplex fiber has higher bandwidth, multimode fiber supports high data rates at short distances. The smaller core diameter of single mode duplex fiber also increases the difficulty in coupling sufficient optical power into the fiber. Relaxed tolerances on optical coupling requirements afforded by multimode fiber enable the use of transmitter packaging tolerances that are less precise, thereby allowing lower cost transceivers or lasers. As a result, multimode duplex fiber optic cable has dominated in shorter distance and cost sensitive LAN applications.

OM3 Multimode 10G Aqua Fiber Optic Cables

The Internet, telephone calls, and cable television all transmit information that can pass through fiber optic cables. Imagine having all this information at lightning-fast speed with less signal disturbances. The mechanics that lie beneath the ingenious work of fiber optic cables rests simply with the fact that light travels faster than electricity with fewer disturbances. The end result? Fiber optic cables provide a quicker and clearer transmission of data. Designed for optimal performance, our fiber optic cables allow you to enjoy the best quality technological experiences possible.

Now, many fibre optic cable suppliers provide a full range of bulk fiber optic cable. Including om3 fiber optic cable, om4 multimode fiber, armored fiber cable, simplex fiber optic cable, multimode duplex fiber optic cable and so on. Today, I will recommended the OM3 fiber optic cable in this blog. Know more OM3 fiber optic cable info and how to choose it.

OM3 10G fiber optic cables are used for 10Gigabit Ethernet applications. These cables are also called multimode OM3 10G Aqua fiber optic cables. Our OM3 10G cables come in various types including different connector types, cable structure and cable length. Our OM3 multimode fiber that are compliant to ISO/IEC 11801 standards. These cables are used for 10Gbps networks to meet the requirement of continuous growing of high data rates.

Big quantity information is generated every day on the internet and people need to exchange more and more information which in turn result in the demand of more and more bandwidth. IEEE802.3ae defined the 10Gigabit Ethernet standards used in LANs. OM3 10G multimode fiber optic cables are developed for such 10Gig Ethernet applications, they are with so called OM3 optical fiber, which is 50/125 type and with industrial acknowledged Aqua color. In FiberStore, we supply the OM3 cable standard color is aqua, but we also supply the customized color service,such as black, blue, orange, green, brown, slate, white, red, yellow, purple, rose, aqua or custom specified. We provide many types of OM3 products, including various kinds of OM3 fiber cable assemblies with various connectors like SC, ST , FC, LC, MTRJ, etc.

OTHER INFO: Which optical fiber should I choose, 50 micron or 62.5 micron?

Although 62.5 micron fiber was the most popular only a few years ago, 50 micron quickly gained market share and is continuing to do so. 50 micron fiber can have up to 20 times the bandwidth (data throughput capacity) of 62.5 micron. For identification purposes, multimode fiber, and also singlemode fiber, is often referred to by its performance level identified by ISO/IEC (International Organization of Standards and International Electrotechnical Committee), which is based on the fibers bandwidth capabilities. 62.5 micron multimode is referred to as OM1. 50 micron fiber is referred to as OM2, OM3 and the recently added OM4. As you would imagine, OM4 has greater bandwidth than OM3 and OM3 has greater bandwidth than OM2.

Fifty micron OM3 fiber is designed to accommodate 10 Gigabit Ethernet up to 300 meters, and OM4 can accommodate it up to 550 meters. Therefore, many users are now choosing OM3 and OM4 over the other glass types. In fact, nearly 80% of 50 micron fiber sold is OM3 or OM4.

If you require higher data rates or plan on upgrading your network in the near future, laser optimized 50 micron (OM3 or OM4) would be the logical choice.

We also supply 10Gig multimode fiber optic cables with various optional structures, such as om3 multimode fiber, om4 multimode fiber, multimode duplex fiber optic cable and so on. Our fiber optic cables are manufactured according to industrial standards and they feature the good price and reliable quality.

Duplex Fiber Among Fiber Optic Cables

Duplex Fiber Cable

Duplex fiber cable is designed for general fiber patch cord production where consistency and uniformity are vital for fast, efficient terminations. We have the right duplex fiber cable in many different outside diameter (OD) sizes and meet all tooling and termination requirements.Duplex Fiber Optic Cables consist of two fibers joined by a thin connection between the two jackets. Workstations, fiber switches and servers, fiber optic modems, and similar hardware require duplex cable. They are used in applications where data needs to be transferred bi-directionally. One fiber transmits data one direction; the other fiber transmits data in the opposite direction. Duplex fiber optic cables from FiberStore can be available in single-mode and multimode.

Multimode vs Singlemode Fiber

A “mode” in Fiber Optic cable refers to the path in which light travels. Multimode cables have a larger core diameter than that of singlemode cables. This larger core diameter allows multiple pathways and several wavelengths of light to be transmitted. Singlemode Duplex cables and Singlemode Simplex cables have a smaller core diameter and only allow a single wavelength and pathway for light to travel. Multimode fiber is commonly used in patch cable applications such as fiber to the desktop or patch panel to equipment. Multimode fiber is available in two sizes, 50 micron and 62.5 micron. Singlemode fiber is typically used in network connections over long lengths and is available in a core diameter of 9 microns (8.3 microns to be exact). Many types of multimode fiber optic cable (such as om3 multimode fiber) and singlemode fiber optic cable for sale in FiberStore.

How Fiber Optic Cables Work

The traditional method of data transmission over copper cables is accomplished by transmitting electrons over a copper conductor. Fiber Optic cables transmit a digital signal via pulses of light through a very thin strand of glass. Fiber strands (the core of the fiber optic cable) are extremely thin, no thicker than a human hair. The core is surrounded by a cladding which reflects the light back into the core and eliminates light from escaping the cable.

A fiber optic chain works in the following manner. At the one end, the fiber cable is connected to a transmitter. The transmitter converts electronic pulses into light pulses and sends the optical signal through the fiber cable. At the other end, the fiber cable is plugged into a receiver which decodes the optical signal back into digital pulses.

Advantages & Disadvantages of Fiber Optic Cable

There are many advantages and disadvantages in using fiber optic cable instead of copper cable. One advantage is that fiber cables support longer cable runs than copper. In addition, data is transmitted at greater speeds and higher bandwidths than over copper cables.
The major disadvantages of fiber optic cables are cost and durability. Fiber cables are more expensive than copper cables and much more delicate.

Three Steps To Pick Out A Fiber Optic Cable
So when you go to pick out a fiber optic cable, there are a few things you’ll want to know. First, make sure that the type of connector you purchase matches your input connection. Second, check to see if your device prefers single or multi-mode transfer. Figure out if you need simplex fiber optic cable or duplex fiber optic cable. And finally, choose which length you need. You can discern this by setting up your system and running a string from the speaker or TV to the equipment. Always buy the next larger length rather than one that is on the small side. You won’t regret it!

The Importance Of Waterproof Cable

The basic mechanical failure mechanism for optical fibres is the slow to rapid growth of any glass imperfections in the fibre caused by the fibre being under stress. This ‘fatigue’ phenomenon can be accelerated with the presence of moisture (H2O) molecules at the glass surface of the fibre. So the waterproof for fiber optic cable is very important . Now let us know more info about waterproof cable.

All manufacturers of fibre optic cables intended for use outdoors must address the issue of protecting the fibre’s glass surface from the presence of moisture. Many manufacturers provide the waterproof characteristic to solve the problem. This is because the 250μm primary fibre coating provides only a 62.5μm-thick layer of UV-cured acrylate material as basic protection over the fibre’s glass surface. This UV-cured acrylate material is not chosen by the fibre manufacturers for its optimal resistance to water or its minimal porosity. It is in fact chosen primarily because of its fast processing speed,since a primary cost driver for fibre manufacturers is the draw speed, which is steadily increasing. The very thin UV-cured acrylate layer is porous to water molecules and will permit concentration of OH-ions at the fibre surface, if the fibre is immersed in water.

All plastic materials are porous to varying degrees. The general category of thermoplastic materials commonly used in cable constructions will to some extent absorb water; however, thermoplastic materials certainly do not act as a complete water block. Only materials like metals or glass can provide a true ‘hermetic’ seal. Plastic materials are generally characterised with parameters such as water absorption and absorption of other common solvents such as oils, gasoline, kerosene, etc. This being the case, water molecules cannot be eliminated from the glass surface of any fibres incorporated in a cable having plastic jackets. The issue is to minimise the concentration of water molecules at the glass surface so that stress crack growth effects are minimised.

There are two different designs approaches to water and moisture protection in fibre optic cables.

The loose tube gel-filled cables must prevent water from reaching the 250μm coated fibres. This approach is to ‘waterproof’ the cable by ‘filling’ the empty spaces in the cable with gel, theoretically preventing water from reaching the 250μm coated fibres. To insure that this is accomplished, the ‘filled’ cables are generally subjected to a hosing test to show that water will not flow through a short section (one meter) of cables. The fact that gels can move, flow, and settle, leaves an uncertainty of the filled level of any particular point of a loose-tube gel-filled cable. This uncertainty of the filling is highlighted by the routine practice of water-blocking the loose-tube gel-filled cables at the entrance to splice housings to keep water from migrating from the cable into the splice housing.

The tight-buffered, tight bound indoor/outdoor cables utilise an entirely different design approach to deal with the moisture issue. Rather than attempting to be ‘waterproof’, they are designed to be water tolerant.

Recognising the porosity of plastic materials and the inherent problems of waterproofing a cable, the moisture protection is concentrated at the fibre surface where it is most needed.

Correctly designed harsh environment tight-buffer systems consist of extremely low moisture absorption coefficient materials at the fibre coating. This provides a buffer system thickness of 387μm over the glass which is more than six times as thick as the 62.5μm coating found in the loose-tube cables.

Buffer materials are low-porosity plastics with excellent moisture resistance. This construction very effectively minimises the water molecule and OH-ion concentration level at the glass surface and virtually eliminates the stress corrosion phenomenon. The tight-buffered design also has the great advantage of being a solid, non-flowing, non-moving structure.
The same level of protection remains in place all along the fibre, regardless of installation conditions, environment, or time.
The balance of the tight-buffered, tight bound cable designs is such that it minimises the open spaces available in the cable structure in which water can reside. Even if an outer cable jacket is cut, or water otherwise enters the cable structure, only a very small percentage of the cross-sectional area is open to water.

1,Water penetration refers to the effectiveness of cable in restricting the longitudinal movement of water or moisture along the core. This requirement is primarily intended to localise any water penetration to minimise the adverse effect on cable performance and to prevent water or moisture leaking into joints and terminations that may cause corrosion problems.
2,Additionally, cable installed underground should have a high density compound sheath material (such as poly ethylene) that provides an adequate barrier to moisture entry to the cable core. The addition of a lapped metal tape (‘moisture barrier’) and/or grease or gel within the core (‘filled’ or ‘flooded’ cable) provides even higher protection against moisture entry.

The above considerations is very important and should always be considered. Always refer to the manufacturers specification sheet and follow their installation instructions.

For the diverse requirements of our customer, we are involved in offering a wide assortment of waterproof cables. FiberStore offer these cables at very economical rates in the market. These cables are widely used and are highly demanded in the market due to their water proof nature.

We provide fiber optic cable products(such as duplex fiber cable,simplex fiber optic cable) are absolutely high quality and low price.

Overview Single Mode Duplex Fiber Cable

Duplex Fiber Optic Cables:

Duplex fiber cables consist of two fibers, either single mode duplex fiber or multimode duplex fiber optic cable, having their jackets conjoined by a strip of jacket material, usually in a zipcord (side-by-side) style. Use duplex multimode or singlemode fiber optic cable for applications that require simultaneous, bi-directional data transfer(One fiber transmits data one direction; the other fiber transmits data in the opposite direction). Duplex fiber is available in singlemode and multimode.

Duplex Fiber Optic Cables have two tight-buffered, up to 900 fibers surrounded by an aramid yarn strength member with a flame retardant outer jacket. The cable allows for flexibility and reliability for use in interconnect. The cable is designed to meet or to exceed the requirements of today’s premise wiring systems.

Duplex multimode fiber optic cable and singlemode duplex fiber cable alike are used for two-way data transfers. Larger workstations, switches, servers, and major networking hardware tends to require duplex fiber optic cable. Duplex cables can be more expensive than Simplex cables, and are compatible with any HDMI extender.

Single Mode Duplex Fiber Cable:

Single-mode duplex fiber optic cable is meant to transmit data over long distances with reliability and high speed. Single-mode cables only carry one ray of light at a time, which is what makes them better for long-distance transmissions. A duplex fiber cable consists of two fibers for simultaneous, bi-directional data transfers, earning the nickname of zip cord fiber optic cable systems.

Single mode duplex fiber is very similar to a multi-mode fiber cable in many ways, with the biggest difference being that the glass center of single-mode cables is significantly smaller, at about 10 microns in diameter. The smaller size is what allows these cables to transmit data across a distance of up to 40 miles with a bandwidth of 1Gbs. However, single-mode cables are usually more expensive than their multi-mode counterparts, so they’re not always a viable option.

As opposed to single-mode cables, which are smaller and are aimed at carrying data across longer distances, multimode cable is better for transmitting data across shorter distances. These cables are larger, and therefore have more bandwidth than their smaller counterparts. It’s important to note that you are capable of running multi-mode cable across a long distance, however, it can limit the bandwidth from 10Mhz to 30Mhz.

Choose the single-mode or multimode duplex fiber cable:

When deciding whether you should install single-mode or multi-mode cable, the first question to address is how far will the data be transmission? This may help in narrowing which optical fiber cable is needed for the project.

If you need to transmit data over a long distance, then single-mode bulk fiber cable is your best bet. With a core between 8 and 10 microns in diameter, these cables can transmit data up to 40 miles with a bandwidth of 1Gb’s. However, single mode transmitters typically use solid-state laser diodes.The higher cost of these optical emitters means that single-mode equipment can be anywhere from two to four times as expensive as multi-mode equipment. Multi-mode equipment will not launch (inject) enough light into a single-mode fiber since the light carrying core of this fiber is only 9 microns in diameter compared to 62.5 microns in diameter for multi-mode fiber. Multi-mode fiber optic cable bulk, which are larger and have more bandwidth, are capable of transmitting data over a few miles, but running the cable that far will limit the bandwidth from 10Mhz to 30Mhz. It’s important to consider all of these factors before you decide which type of fiber optic cable is best for you.

FiberStore is your fiber optic cable specialists. We provide a full range of fiber optic cable,such as a fantastic selection of singlemode duplex 9/125 fiber optic cable – ideal for low-loss, high bandwidth transmissions over long distances.Do you want to know more info about cost of fiber optic cable or fiber optic cable specifications,pls focus on our blog or our company .

An Overview Of The Armored Fiber Cable

Fiber optic cables form one of the most important parts of the networking industry today. Fiber cables are composed of one or more transparent optical fibers enclosed in a protective covering and strength members. Fiber cables are used to transmit data by the mode of light. Various types of fiber cables available are multimode duplex fiber cables, single mode simplex fiber cables, single mode duplex fiber cables, armored fiber cables and plastic optical fiber cables.

What is Armored Fiber Cable

Armored Fiber Cable, is outside the optical fiber is then wrapped in a layer of protective of “armor”, is mainly used to meet the requirements of customers rodent, moisture proof, etc. Armored cable is a power cable made up by assembling two or more electrical conductors, generally held together with an overall sheath. This electrical cable with high protective covering is used for transmission of electrical power, especially for underground wiring needs. However, these cables may be installed as permanent wiring within buildings, buried in the ground, run overhead, or may even be kept exposed. They are available as single conductor cable as well as multi-conductor cables.

Common Armored Fiber Cable

Armored fiber optic cables are often installed in a network for added mechanical protection, as they have extra reinforcing in the cable housing to prevent damage. Two types of armored fiber optic cables exist: interlocking and corrugated. Interlocking armor is an aluminum armor that is helically wrapped around the cable and found in indoor and indoor/outdoor cables. It offers ruggedness and superior crush resistance. Corrugated armor is a coated steel tape folded around the cable longitudinally. It is found in outdoor cables and offers extra mechanical and rodent protection.

Armored Flame Retardant Fiber Optic Cable for Indoor/Outdoor Applications

Indoor/outdoor fiber optic cables have been pretty hot in the last several years and there are good reasons for this. For service providers, indoor/outdoor fiber cables really present big time and cost savings. This cable design can come from the outdoor environment and enter a building without the need to switch cable designs to have the flame retardance required indoors. This dual purpose cable can reduce the cost of the terminations and related labor to change cable designs.

The development of dry water blocking core technology has also helped indoor/outdoor fiber cable development. This dry core technology uses water swellable materials to block the flow of moisture in the longitudinal direction.We also provide other types of fiber optic cable,such as the waterproof cable,waterproof fiber pigtail cable can be used in harsh environment. It is mainly used in outdoor connection of the optical transmitter. Waterproof fiber pigtail is designed with a stainless steel strengthened waterproof unit and armored outdoor PE jacketed cables.
