Selecting The Appropriate Fiber Optic Cable


Fiber optic cable has turned into a standard component in many contemporary cable infrastructures. Its immunity to electromagnetic interference (EMI) and radio frequency interference (RFI) turn it into a desirable cable medium. Its function to safeguard the fibers during its stallation and also the service lifetime. Its capability to transport signals for significant distances has also earned it a place in many networks, whether they are local, wide area or metropolitan. In reality, fiber optic cable is currently run down many residential streets and brought straight to the home. This website will try to inform us how to choose the right fiber optic cable plus some basic fiber optic cable specifications.

Whenever you used fiber optic cable?

Fiber optic cables can transport more data and do this on the greater distance than typical copper communication cables. Fiber is utilized to link the networks of buildings together, link the dorms and buildings on a college campus, and today, link a growing number of residential customers to their television and telephone providers. In most a commercial building, however, fiber can be used to join the main distribution frame (MDF), where typically network servers reside, to telecommunication closets (TC) through the building.

For instance, a little cluster of cubicles as well as their occupants may be located 500 feet in the MDF. You would like to supply of their computers around the network. Since standard copper communication cables are restricted to 295 feet of installed cable, they won’t work on that distance. Multimode fiber is the solution. The cubicles can be wired with copper communication cables to some nearby enclosure. By placing the network switches and including a media converter in that enclosure, you may use a fiber optic cable to bridge the 500-foot gap. A media converter in the opposite end from the fiber optic cable completes the channel.

The above scenario describes a normal use for multimode duplex fiber optic cable inside a building. However, it’s just one of these of the way fiber optic cable can be employed for your transport of data. Fiber optic cable can also be installed where space is an issue since one small fiber optic cable can replace a huge selection of copper communication cables.

Pick the 50 micron or 62.5 micron?

Although 62.5 micron fiber was the most popular just a few years back, 50 micron quickly gained business and is also still achieve this. 50 micron fiber may have approximately 20 times the bandwidth (data throughput capacity) of 62.5 micron. For identification purposes, multimode fiber, as well as singlemode fiber, is frequently known by its performance level identified by ISO/IEC (International Organization of Standards and International Electrotechnical Committee), which is depending on the fibers bandwidth capabilities. 62.5 micron multimode is referred to as OM1. 50 micron fiber is known as OM2, OM3 and the recently added OM4. When you would imagine, OM4 has greater bandwidth than OM3 and OM3 has greater bandwidth than OM2.

50 micron OM3 fiber is designed to accommodate 10 Gigabit Ethernet as much as 300 meters, and OM4 can hold it to 550 meters. Therefore, many users are now choosing OM3 and OM4 on the other glass types. In fact, nearly 80% of fifty micron fiber sold is OM3 or OM4. Many fibre optic cable suppliers provide many kinds of OM4 multimode fiber,such as om4 mpo cable for sale in FC,LC, SC, ST, MU, and MTP connector.We can customize patch cables in any cut length.

Four steps to choose the fiber optic cable outer sheath:

1. You’d better choose Armored Fiber Cable when use cable directly buried outdoor. And judge black plastic outer sheath cable with two roots and over two root.
2. Pay attention to the characters of flame retardant, poison and smoke when use cable inside building. Generally, use flame retardant and smoke type cable within the pipeline. And choose flame retardant, smokeless and non-toxic enter exposed environment.
3. Choosing distribution cables in the apartment building vertical wiring. Breakout cables are employed to Level wiring type.
4. The best option to choose multimode optical cable when the transmission distance is under 2 km. Within the other sides, use single-mode optical cable when the transmission is a lot more than 2 km.

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.

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.
