Plastic Optical Fiber System

Share

There are numbers of services providing large-volume information content, such as high-definition movies, continues to increase rapidly. Single-mode glass optical fiber has been widely deployed in data trunk lines and pipelines to connect large cities and nations. It has already become indispensable as an information transmission medium. However, SM GOF is mechanically weak and lacks sufficient bending ability. Moreover, as the core diameter is very small, just 10 um, extremely precise techniques and expensive devices are required to connect fibers to signals receiving devices.

Because of this, SM GOF is rearly used for very short reach networks, such as local area networks in buildings. Facing this “last hundred meters” problem in optical fiber infrastructure, plastic optical fiber has obvious advantage over it:

POF fiber is made out of a plastic such as acrylic (PMMA) as the core material and fluorinated or perfluorinated polymers as the cladding materials. It carries optical signals along a core made from plastic, instead of the more traditional silica, the price of which is much cheaper. It can cost approximately one fifth as much as comparable glass fiber. Which puts it within reach of more consumers. Customers who want to connect to the silica fiber optical network maintained by a telecommunications company usually cannot afford traditional optical fiber for internal wiring, but the plastic optical fiber can help to make the connection.

Plastic optical fiber (POF) systems offer the promise for low cost applications in communications, data transmission, illumination, lighting, imaging, sensing and light transmission. Plastic fiber optic systems provide the same advantages of glass optical fiber (GOF) but at lower cost and easier use. Glass optical fiber systems have received more attention than POF, mainly due to their rapid acceptance in telecommunications as data rates up to 100 Mbps and distance up to 100 meters.

Plastic fiber optic cable systems are also finding increased applications for sensors and lighting. The technology is also moving rapidly as evidenced by recent papers on multimode and single mode POF, high temperature fiber, integrated POF circuits, laminated lightguides, discrete components both active and passive, optical switching, and other developments too numerous to mention.

However, POF has two important weaknesses: it has significantly lower bandwidth than GOF, and its attenuation is far higher. Recent developments conquering both of these issues now mean that POF is regarded as the strongest candidate at present for optical data transmission over the last hundred meters.

How To Install and Test the Fiber Optic Cables

Share

In the telecommunications industry today, how to install the fiber optics that each optical engineer must learn in their work. Don’t froget, when you install the fiber optics, you must testing your fiber optic system. Optical-fiber testing is one of the final and most important procedures in installing optical networks.

How to install the fiber optic cable?

Fiber optic cable may be installed indoors or outdoors using several different installation processes. Outdoor cable may be direct buried, pulled or blown into conduit or innerduct, or installed aerially between poles. Indoor cables can be installed in raceways, cable trays,placed in hangers, pulled into conduit or innerduct or blown though special ducts with compressed gas. The installation process will depend on the nature of the installation and the type of cable being used. Installation methods for both wire and optical fiber communications cables are similar. Fiber cable is designed to be pulled with much greater force than copper wire if pulled correctly, but excess stress may harm the fibers, potentially causing eventual failure.

The install fiber optic cable tips:

a) Follow the cable manufacturer’s recommendations. Fiber optic cable is often custom-designed for the installation and the manufacturer may have specific instructions on its installation.
b) Check the cable length to make sure the cable being pulled is long enough for the run to prevent having to splice fiber and provide special protection for the splices.
c) Try to complete the installation in one pull. Prior to any installation, assess the route carefully to determine the methods of installation and obstacles likely to be encountered.

Testing fiber optic cables steps:

After installation, test each fiber in all fiber optic cables for verification of proper installation. Perform the following tests:
a) Continuity testing to determine that the fiber routing and/or polarization is correct and documentation is proper.
b) End-to-end insertion loss using an OLTS power meter and source. Test multimode cables by using TIA/EIA 526-14 Method B, and single-mode cables using TIA/EIA 526-7 (single-mode). Total loss shall be less than the calculated maximum loss for the cable based on appropriate standards or customer specifications.
c) Optional OTDR testing may be used to verify cable installation and splice performance. However, OTDR testing shall not be used to determine cable loss.
d) If the design documentation does not include cable plant length, and this is not recorded during installation, test the length of the fiber using the length feature available on an OTDR, or some OLTSs.
e) If testing shows variances from expected losses troubleshoot the problems and correct them.

Basic Knowledge About Fiber Optic Cable

Share

From data and voice to security and video conferencing, many of today’s IT infrastructure services rely on fiber optics to transmit information faster, farther, and in greater amounts than ever before. So fiber optics are more and more popularity in our internet. This post will try to answer some of the basic questions about fiber optic cable.

What Is Fiber Optic Cable?

A fiber optic cable is a network cable that contains strands of glass fibers inside an insulated casing. These cables are designed for long distance and very high bandwidth (gigabit speed) network communications.

Fiber Optic Cable

Single Mode vs. Multimode Fiber Optic Cable

Single mode fiber gives you a higher transmission rate and up to 50 times more distance than multimode, but it also costs more. Single-mode fiber has a much smaller core than multimode fiber-typically 5 to 10 microns. Only a single lightwave can be transmitted at a given time. The small core and single lightwave virtually eliminate any distortion that could result from overlapping light pulses, providing the least signal attenuation and the highest transmission speeds of any fiber cable type.

Multimode fiber gives you high bandwidth at high speeds over long distances. Lightwave is dispersed into numerous paths, or modes, as they travel through the cable’s core. Typical multimode fiber core diameters are 50, 62.5, and 100 micrometers. However, in long cable runs (greater than 3000 feet (914.4 ml), multiple paths of light can cause signal distortion at the receiving end, resulting in an unclear and incomplete data transmission. For example, you can try to compare the single mode duplex fiber vs multimode duplex fiber optic cable, and well know they are different.

The Relationship between Fiber Optic Cable and Fiber Patch Cord

A fiber patch cord is a fiber optic cable capped at either end with connectors that allow it to be rapidly and conveniently connected to CATV, an optical switch or other telecommunication equipment. Its thick layer of protection is used to connect the optical transmitter, receiver, and the terminal box. This is known as “interconnect-style cabling”.

What Types of Connectors Should be Used for Fiber Optic Cable?

There are a number of connector styles on the market including LC, FC, MT-RJ, ST, and SC. There are also MT/MTP style connectors that will accommodate up to 12 strands of fiber and take up far less space than other connectors. This connector is intended for use with indoor loose tube no-gel cable constructions. However, the most popular connectors are SC, which pushes in then click when seated, and ST, also known as bayonet style, that is pushed in and twisted to lock. That should be a consideration when making product selections.

What kind of jacket rating and type do you require?

Fiber cable jackets come in many styles. As an example, fiber can be Indoor only, Outdoor only, Indoor/Outdoor, Tactical and it can also have Plenum or Riser ratings.

Jacket color is relatively standardized.

a) Multimode = Orange

b) 50/125um 10G = Aqua

c) Single Mode = Yellow

d) Indoor/Outdoor or Outdoor = Black

e) Custom jacket colors are also available for indoor fiber cables

Various Advantages Of Fiber Optic Cables

Share

Communication industry has been stormed by the advent of fiber optic cable. The main advantages offered by these cables include a wider bandwidth, light weight, small size and in any case has more flexibility. In addition to it, the core reason behind its popularity is that advanced technology used by these cables. As we know the fiber optic cable, the fiber optic cable is a cable containing one or more optical fibers. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable will be deployed. For example, the 10g fiber cable is has plastic layers and contained in a protective tube, we can offer different jacket color and any length are available for these cables .

In fact, the whole fiber optic technology makes use of fiber optics. The typical fibers today are made out of glass or plastic since it is possible to make them thin and long. Also both glass and plastic are transparent at particular wavelengths, which allow the fiber to guide light efficiently. These optical fibers are thin, ultra-flexible and transparent and transmit the light between two ends of the fiber quality as compared to copper wire. So, with their superior technology these are more appropriate for smooth communication between far distances. In addition to it, the usage of these cables results in much less loss of signals which means uninterrupted and smooth communication. More than 80% of the distance data traffic through the intelligent use of these fiber optic technology is transferred.

Other advantages of fiber optic cables include it is inexpensive and suits properly to extremely thin diameters in the range between 0.8mm to 40mm. Will be extremely thin, a number of fibers run together along many connections in the same cable. It provides a clearer telephone lines and TV reception, as the light signals that are in the same cable does not interfere with each other to function. This ultimately leads to less loss of signal. These cables can also be called as the safer ones because no electricity passes through these cables and hence there will not be any fire issues.

In comparison with other lines such as copper wires, these cables are definitely the superior ones because they are lightweight and small sized. With the above advantages, it is obvious why fiber optic cables that are used in many telecommunications and computer networks. These cables are the most trusted and best replacement of copper cables.

Knowledge about Fiber Optic Pigtails

Share

Much about the tech jargon, some people don’t know its meaning. Such as fiber optic pigtails, fiber pigtail is a piece of fiber optic cable with only one fiber optic connector on one side of the cable, there are single mode and multimode fiber optic pigtails, which can be with various types of fiber optic terminations such as SC, FC, ST, LC, MU, MT-RJ, MTP, MPO, etc. the fiber optic pigtail with connector side is used to link the equipment, while the other side of the pigtail is melted together with the fiber cable, by melting together the fiber glasses, it can reach a minimum insertion loss. Fiber optic pigtails are usually used with fiber optic management equipment like ODF, splice closures and cross cabinets. Common types of fiber optic pigtails are usually with 0.9mm fiber cable diameter, and usually installed inside ODF unit. Most commonly used types are SC fiber optic pigtail, ST fiber optic pigtail,FC fiber optic pigail, LC fiber optic pigtail ,MT-RJ fiber optic pigtail,SC/APC fiber optic pigtail, FC/APC fiber optic pigtail and E2000 fiber optic pigtail. They are single mode types and multimode types.

A fiber pigtail is really a single, short, usually unbuffered, optical fiber which has an optical connector pre-installed on one end along with a period of exposed fiber in the other end. The end of the pigtail is stripped and fusion spliced to a single fiber of a multi-fiber trunk. Splicing of pigtails to each fiber within the trunk “breaks out” the multi-fiber cable into its component fibers for connection to the end equipment.Fiber pigtails can have female or male connectors. Female connectors might be mounted in a patch panel, often in pairs although single-fiber solutions exist, to allow them to be connected to endpoints or other fiber runs with patch fibers. Alternatively they can have male connectors and plug directly into an optical transceiver.As the fibers must have connectors fitted before they can affix to other equipment. Fiber pigtails may be one of the common solutions for fiber cable termination, the inclusion of connectors to every optical fiber in a cable.

According to the ITU-T (International Telecommunication Union Telecommunication) standardization organization, fiber optic pigtails are categorized into Fiber pigtail that conforms to G.652 and G.653 fiber splicing technology standard. Fiber optic splicing technology is primarily to use a fiber splicing machine to fuse splice the fiber with fiber or the fiber with fiber pigtails. In this process, the bare fibers of the fiber optic cables are fuse spliced with the fiber pigtails to become a whole. With the fiber optic connector at one end of the fiber pigtails, they are connected to fiber optic transceivers, the optical fibers connected with the twisted pairs, and then connect with the information outlets. Main tools used in the fiber splicing technology include fiber termination box, fiber optic converter, fiber optic transceiver, fiber pigtail, optical fiber coupler, fiber stripper, and fiber optic cleaver, etc. Currently fiber optic pigtail with SC, ST, FC, LC MT-RJ, SC/APC, FC/APC, E2000 fiber optic connectors are available in the market.

Fiber patch cables would be the backbone of the fiber optics industry. Fiber Patch (Fiber Patch Cable or Fiber Jumper) is strands of optically pure glass as thin as real hair. Fiber patch cable is definitely an fiber cable which has fiber connectors placed on one ends. General utilization of these cable assemblies includes the interconnection of fiber cable systems and optics-to-electronic equipment. Another information on patch cable, if the fiber connectors are affixed to just one end of the cable, it’s called the fiber optic pigtails, in the event the fiber connectors are affixed to both ends, it is known as a fiber jumper or fiber patchcord.

Fiber Patch Cables Types

Given the high diversity you could face when trying to select a fiber patch, professionals happen to be classifying them to simply communication and organization. There are lots of ways to classify fiber patch cables:

Fiber cable type based classification:

Simplex and Duplex are the two main types of fiber cable. Simplex fiber patch cables feature one fiber then one connector on each side. A Duplex fiber optic cable has two fibers and a couple connectors on both ends.

Termination connector type based classification:

As with any connection system, termination types and compatibility are crucial.

There are generally two methods to terminate a fiber cable:

Indentical connector type for both ends of the cable; two different kinds (Hybrid) of connectors on each side with the cable.

Supported optical fiber modes based classification:

There are 3 different modes available when operating fiber patchcord: singlemode, multimode, and 10 Gigabit multimode.

Size from the fiber cable based classification:

Manufacturers make Fiber Optic Patch cord in the following sizes: 250 um, 900 um, 1.6 mm, 2.0 and 3.0 mm fiber optic cable.

Information About Cable Components

Share

Pick up any cabling catalog, and you may locate a variety of components and associated buzzwords that you never dreamed of. Including patch panel, wall plate, plenum, modular jacks, raceways, fiber optic pigtails and patch cords are only a few. Exactly what do all of them mean, and just how are these elements used to create a structured cabling system?

In this blog, we’ll provide some information about the structured cabling system so that you won’t feel so confused next time you select up a cabling catalog or assist professional cabling installers. Today, we mainly explain the cable components relevant information. If you wish to find out about components, pls visit FiberStore Tutorial, we provide some detail information regarding the fiber optic components.

We’ll describe the constituents involved with transmitting data from the work area towards the telecommunications room or enclosure. These major cable components are horizontal cable, backbone cable, and patch cords used in cross-connections and then for connecting to network devices.

Horizontal and Backbone Cables

The terms horizontal cable and backbone (sometimes called vertical or riser) cable do not have anything regarding the cable’s physical orientation toward the horizon. Horizontal cables run between a cross-connect panel in a telecommunications room and a telecommunications outlet located near the work area. Backbone cables run between telecommunications rooms, and enclosures,as well as the main cross-connect point of a building (usually found in the equipment room). The photo illustrates the standard components seen in a structured cabling environment, like the horizontal cable, backbone cable, telecommunication outlets, and patch cords.

Fiber Patch cord

Fiber patchcord can be used in patch panels to supply the link between field-terminated horizontal cables and network connectivity devices (for example switches and hubs) and connections between the telecommunications outlets and network devices (including computers, printers, as well as other Ethernet-based devices). They are the part of the network wiring you could see. As the saying goes, a sequence is merely as strong since it’s weakest link. Due to their exposed position in structured cable infrastructures, patch cords are nearly always the weakest link.

Whereas horizontal UTP cables contain solid conductors, patch cords are created with stranded conductors because they’re more flexible. The flexibility allows them to withstand the abuse of frequent flexing and reconnecting. Although you could make your own field-terminated patch cords, we strongly suggest against it.

The manufacture of patch cords is quite exacting, and even under controlled factory conditions it is difficult to attain and guarantee consistent transmission performance. The first challenge lies inside modular plugs themselves. The parallel alignment from the contact blades forms a capacitive plate, which gets to be a source of signal coupling or crosstalk. Further, the untwisting and splitting of the pairs as a result of the termination process raises the cable’s susceptibility to crosstalk interference. In the event that weren’t enough, the mechanical crimping method that secures the plug towards the cable may potentially disturb the cable’s normal geometry by crushing the conductor pairs. This is another supply of crosstalk interference along with a source of attenuation.

Tip:Patch cords which were factory terminated and tested are required to achieve consistent transmission performance. At first, patch cords seems to be a no-brainer, nevertheless they could possibly function as the most important element of accurately specify. When specifying patch cords, it’s also possible to require your patch cords be tested to make sure that they fulfill the proper transmission-performance standards for category.For more information about fiber optic patch cable types or want to buy the patch cable, pls contact this email: sales@fs.com.

Common Kinds of Hybrid Fiber Patch Cord

Recently, it is now apparent that fiber optic cable is steadily replacing copper wire as an appropriate way of communication signal transmission. They span long distances between local telephone systems in addition to supplying the backbone for a lot of network systems. Other system users include cable tv services, university campuses, buildings, industrial plants, and electric utility companies. A fiber-optic method is just like the copper wire system that fiber-optics is replacing. For example, fiber patch cord is one of the most often used components inside the fiber optic network.

Fiber patch cable (also referred to as fiber jumper cable or fiber patchcord) is used for connecting one optical device to a different, sometimes with two different connection types. You can find 4 connector types: LC, SC, ST and MTRJ which may be arranged in a configuration to match your connection needs. Including SC fiber cable (SC LC fiber patch cord), LC fiber patch cable (LC to ST fiber cable), ST fiber patch cable (ST to LC fiber patch cable, ST to SC fiber patch cable), ect.

Connector Types:

1. Same connector type fiber patch cable: This fiber optic patch cable gets the same type of connector on both ends, for example ST, SC, LC, FC, MTRJ, E2000, MU, etc.

2. Hybrid fiber optic patch cables: This fiber optic patch cable has different connectors on each end. One end could be SC and the opposite end could be LC, ST, FC, MTRJ, E2000, MU, etc.

We must learn more details about the fiber optic patch cable types, for instance, the hybrid fiber optic patch cables, LC to ST fiber cable is terminated with LC fiber optic connectors on a single end and ST fiber optic connectors however. Called Lucent Connectors, Little Connectors or Local Connectors, these snap-in connectors are typically useful for high density connections and are compatible with plug-and-play devices for example SFP modules and XFP transceivers. Straight Tip (“ST”) connectors use a bayonet-style coupling type, enabling a simple twist-on and twist-off installation. Do not let many of these connectors of different shapes and sizes fool you. Different devices opt for different connector types.

FiberStore provides different types of fiber patch cords including common single-mode 9/125, OM1 62.5/125, OM2 50/125, 10G OM3/OM4 patch cables, armored patch cable, fiber optic pigtails, multi core patch cables, MPO/MTP fiber and other special patch cables. Should you ever have a career that requires fiber patch or another type fiber optic products related and are not able to find the products on FiberStore, don’t get discouraged. Instead, give us a call or even an email, we are able to assist you in finding what you want as well as make it custom.

Common Types of Fiber Patch Cables

In the event you working in telecommunications industry, acquiring thorough information about fiber optic patch cables is essential. Fiber optic cable are used for linking the apparatus and components in the fiber optic network ,they are with various types of fiber optic connector types. The fiber optic patch cord types are classfied by the fiber optic connector types. For example,we name LC fiber patch cable since this cable is to use LC fiber optic connector. You will find PC,UPC,APC type fiber patch cord, they’re different as a result of polish of fiber connectors. Fiber optic patch cables are available with ST SC LC FC connectors.Fiber optic patch cables may be split into different types according to fiber cable mode, cable structure, connector types, connector polishing types and cable sizes. However nowadays I would like to based on fiber connectors to introduces the normal kinds of fiber patch cable.

Common Forms of Fiber Patch Cable:

SC Fiber Optic Patch Cord
SC fiber optic patch cable is one of the earliest type and something of the very most commonly used fiber optic cable, it is simple to use and value saving, SC fiber cable is widely uesed in fiber optic networks. SC fiber patch cable is by using zirconia sleeve and plastic housing. Oahu is the standard fiber optic cable assemblies, with simplex, duplex patch cords and standard pigtails.

The SC fiber optic patch cord was invented by the Japanese company NTT. It really is probably the most popular fiber optic patch cords. SC fiber optic patch cord features low priced , simplicity along with good durability, SC fiber optic patch cords is with a locking tab about the cable termination, it’s a push and pull type fiber optic connector.

FC Fiber Optic Patch Cord
FC fiber optic patch cords are with FC fiber optic connectors ,the industry screw type connection. FC fiber optic patch cords were quite definitely popular previously ,but people have a tendency to use LC and SC to switch FC more and more. It’s the standard fiber optic cable assemblies, with simplex, duplex patch cords and standard pigtails.

The FC fiber optic patch cable comes in both singlemode and multimode versions, and it is fully intermateable with NTT-FC products. Both smf and mmf versions FC fiber optic patch cord have a zirconia ceramic ferrule with pre-polished PC profile and convex spherical end.
