Plastic Optical Fiber System


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.

Then, how many fiber patch cables does FiberStore provide? It is hard to give an actually number, because it is too many to calculate. To better interpret this answer, let's start an overview on FiberStore fiber patch cable types:
It is well known that an optical fiber patch cord is composed of a fiber optic cables with two fiber connectors terminated on each end. It is typically used to in computer work station to outlet and fiber optic patch panels or optical cross connect distribution center. According to common cable structures, functions, and major applications, fiber patch cable can be divided into different types: common fiber patch cables, armored fiber patch cables, fiber optic pigtails, mpo/mtp fiber cables, fiber pigtails, multi-core fiber patch cables, and other special patch cables such as volition fiber patch cables, military grade patch cables, pre-terminated fiber cables, etc.
Common fiber patch cables
Common fiber patch cables refer to patch cables that commonly structured with fiber, out sheath and tight buffer. According the fiber fiber types, common fiber patch cables are generally divided into OM1 multimode, OM2 multimode, 10G OM3 and 10G OM4 types. All of them can terminated with a variety of connector types such as LC, SC, ST, FC, MU and MTRJ.
Armored Fiber Patch Cables
Armored fiber patch cable can be understanded as the armored fiber optic cable terminated with fiber connectors on each end. This patch cable use rugged shell with aluminum armor and kevlar inside the jacket, and it is 10 times stronger than common fiber patch cable. This will help make the armored fiber patch cord resistant of high tension and pressure. We supply armored fiber optic patch cable, including 10G OM4/ OM3, 9/125, 50/125, 62.5/125 fiber types.
Multi Core Fiber Patch Cables
Multi core fiber patch cord are individually reinforced fibers terminated with fiber optic connectors. When the optical fiber is terminated on both ends it is termed as patch cord. The multi core patch cable is widely used for CATV, LANS, Telecom, Video, active device termination, telecommunication networks and Gigabit. Varies connector types are available including SC, SC/APC, FC, FC/APC, LC, ST.
Fiber Optic Pigtails
Pigtail fiber optic cable can be get by cutting the fiber patch cables in the middle, so that the pigtail is an fiber patch cable with fiber connector at only one side to link to the equipment while the other side can be melt with optical cables fibers. FiberStore supply 10G 50/125, 62.5/125, 50/125 multimode optic pigtail with SC, ST, FC, LC MT-RJ, SC/APC, FC/APC, E2000 fiber optic connectors.

Fiber Resistant LS0H Cables


With the increased demand for safety in public areas and buildings, contractors are now being advised to install materials thar are zero halogen cables to peoples in case of fire. It is now understood that smoke and poisonous fumes can be a greater risk to lives than that of fire alone.
What is Resistance to Fire?
Resistance to fire is the property of a material of assembly to withstand fire or give protection from it and it is measured as the time a product can mantain a level of functionality during a fire.
Fire resistance may be built-in both structurally and by the correct choice and application of building materials. The resistance-to-fire (of a cable) is the term used to describe how long a cable continues to operate in a fire. This may be of primary concern, for instance, in life safety of fire fighting installations.Cable resistance to fiber concerns: the ability of a cable to maintain functionality during fire; the duration of survival in working condition.
To be assured you are buying a cable that will offer security during fire, it must pass 3 tests pertaining to halogen content, low smoke density and flame propagation. The resistance-to-fire performance of cable is indicated in term of survival time which are 15, 30, 60, 90 and 120 minutes of operation in a standardized fire condition at European Level and equipment international (IEC). Local standards and customers specs include their own requirements witch are achieved as well by FiberStore local or tailor-made products.
Fiber-retartant, low smoke halogen free cable (LSZH) and wire has been commercially available fro shipboard applications since the 1970S, offshore marine platforms, rapid transit and similar applications where people are present in confined areas. When worked with other fiber prevention and suppression practices, fire-retardant LSZH cables can help minimize fire-rated deaths and property damage. However, gases produced by all burning materials - whether LSZH or not - are extremely toxic.
Advantages and Disadvantages of LS0H cables
Pro: LSZH wire and cable produces less smoke when burned, which permits people to exit a burning building more quickly and results in less damage.
Con: Because LSZH is more susceptible to jacket cracking caused by pulling lubricants or cable bending, special lubricants has been developed to minimize cable damage during installation.
Pro: Because LSZH releases little or no halogen gas when burned, it reduced the damages to the human respiratory system if inhaled and contributes to less corrosion damage to equipment near the fire.
Cons: LSZH jacket compounds usually have very high filler content to provide the required flame and smoke performance. As a result, most have poorer mechanical, chemical resistance, water absorption and electrical properties than non-LSZH compounds.
Pro: LSZH jackets have a lower coefficient of friction than some non-LSZH jackets, which can make installatin easier.
Cons: The current generation of LSZH cables has not yet established a proven history of long-term performance.

What's the Difference Between Optical Fiber Patch Cable and Fiber Pigtails


Q: What's the difference between fiber pigtail & fiber patch cord. Can we use a patch cord as pigtail by cutting in the middle of the cable?
I find such questions now and then on the Internet, it's true that there are still some peoples that are not familiar with but still interested in such knowledges. Keep this in mind, we would like to take this topic into the discussion by collecting opinion from related answers:
For some people, an optical fiber patch cable is ruggedise (providing additional fiber protection) and a pigtail is not (and therefore more brittle).
"I would expect pigtails while dealing with optical components, while when dealing with patch panels, equipment interconnections, etc. I would expect patch cables." "I would also expect patchcables to be double-ended (i.e computerized at both ends) and pigtails to be single-ended (or not terminated)."
Patch cables have connectors on both ends. While pigtails have a connector on one end and bare fiber on the other.
In my opinion, i would agree all of the above comments, and also give the simplest understanding of myself: the fiber optic patch cable = fiber optic connector + fiber optic cable + fiber optic connector, while the fiber optic pigtail = fiber optic connectors + fiber optic cable. We can really use a patch cord as pigtails by cutting in the middle of the cable.
Officially speaking, fiber optic patch cable, often called fiber optic patch cord or fiber jumper cable, is a fiber optic cable terminated with fiber optic connectors on both ends. I have two major application areas: computer work station to outlet and fiber optic patch panels or optical cross connects distribution center. Fiber optic patch cables can be divided into different types based on fiber mode, cable structure, connector types, connector polishing types and cable sizes. All types of fiber optic patch cables can be found at FIBERSTORE.COM, LC patch cable is the most commonly used, other connector types include ST, SC, FC, etc. Which can be either the same types of connector on both ends, or different connectors on each end (Hybrid fiber optic patch cables).
Fiber optic pigtail is a piece of cable terminated with fiber optic connectors at only one side of the cable while leave the other side no connectors, so that the connector side can link to the equipment and the other side can be melted with optical cable fibers. Pigtail fiber optic cables are usually used with fiber optic management equipment like ODF, splice closures and cross cabinets.
Commonly used fiber optic pigtails types are FC, LC, MU, E2000, MTRJ and ST pigtail. According to the fiber mode types, there are single mode types and multimode types.
The pigtail, when separate from a line, looks like a bundle of loose, capped wires that are bound together at one end. The bound end connects to the main cable, where the individual strands of the fiber pigtail are permanently fused, or spliced, to the multicore cable. When the process is complete, the pigtail is a non-removable piece of the system.

Classification of Fiber Optic Patch Cords


This article is designed specially for those who want to quickly while without going into details to understand the wide range of fiber patch cable types.
What is fiber optic patch cord?
Fiber optic patch cable, which is often referred to as fiber optic patch cord or fiber jumper, is the segment of fiber optic cable with optical connectors on both ends. It applies in two main areas: a computer work station - the output fiber optic patch panels or optical cross - rapredelitelny center. Optic patch cords are used only indoors.
The most common types of optical patch cords
Fiber optic patch cords can be divided into different types depending on the type of optical fiber structures such as optical connectors, polishing type and cable length.
Fiber type of fiber optic cable
Single-mode optical fiber patch cables (SM): A single mode fiber patch cord consists of a piece of fiber optic cable with a core diameter of 9/125 micron, terminated on both sides of single-mode optical connectors. Sheath-mode fiber optic cable usually has a yellow color.
Multimode fiber patch cables (MM): Multimode optical patch cord consists of a piece of multimode fiber optic cable with a core diameter of 62.5/125 microns or 50/125 microns connectorized on both sides with multimode connectors. The shell of a multimode fiber optic cable, usually has an orange color, and the connectors are gray.
10G multimode fiber optic patch cable (such as OM3, OM4): 10Gib multimode optical fiber patch cable 50/125 micron is specially designed and optimized for laser VCSEL (Vertical Cavity Surface
Emitting Laser - semiconductor vertical cavity lasers) is based on 10Gig Ethernet. They have backward compatibility with existing network equipment and provide the bandwidth three times larger than conventional optical fibers with a core diameter of 62.5/125nm. 10Gib is targeted at distances up to 300 meters using a wavelength of 850nm. The shell of such a cable is usually celadon.
Structure of the fiber cable:
Simplex optical cords: an optical fiber patch cable has a single fiber cable and one connector on each end.
Duplex optical cables: double optical patch cord has two fibers with two connectors on each end. Each fiber is marked with a marker to indicate polarity.
Ribbon optical cords: ribbon cable has one connector on one side, such as MTP (12 fibers) and other multiple fiber optic cables with connectors SC, LC, FC, etc.
Difference in the types of optical connectors:
Optical cable with identical connectors: the optical connectors on both ends of the optical fiber patch cable is the same.
Transient optical cables: fiber optic patch cord has different optical connectors on the ends of fiber optic patch cord, allowing connection of equipment with different optical adapters.
Difference in the type of polishing
Fiber optic connectors are designed and polished to different shapes. This is done in order to minimize back reflection. This is especially important when using a single-mode optical fiber. Back
reflection depending on polishing can have the following values: -30 dB, -40 dB, -50dB and -60dB.
PC (Physical Contact): Typical back reflection < - 40 dB for single-mode and multimode optical fibers.
UPC (Ultra Physical Contact): Typical back reflection < -50 dB for single-mode optical fiber. (usually connector SC, LC blue, and shanks to the FC and ST - Black)
APC (Angled Physical Contact), angular polishing: Typical back reflection < - 60dB for single-mode optical fiber. (Connector SC, LC and FC shank on ST and green)

Typical Cable Components for Network Connection


This article will describe some typical cable components involved in transmitting data from the network area to the telecommunications room or enclosure. These typical cable components are horizon cable, backbone cable, and patch cables which is used in cross-connections and for connecting to network devices.
Patch Cords
Patch cords are used in in patch panels to provide the connection between field-terminated horizontal cables and network connectivity devices and connections between the telecommunications outlets and network devices such as printers, computers, and other Ethernet-based devices. They are part of the network wiring you can actually see. Since the fact that a chain is only as strong as its weakest link. Because of their exposed position in structured cable infrastructures, patch cords are always the weakest link. Patch cords include optical fiber patch cable.
Horizontal and Backbone Cables
The name horizontal cable and backbone cable have nothing to do with the cable's physical orientation toward the horizon. Horizontal cables run between a cross-connect panel in a telecommunications room and telecommunications room and a telecommunications outlet located near the work area. Backbone cables run between telecommunications rooms, and enclosures, and the main cross-connect point of a building, it usually located in the equipment room.
Whereas horizontal UTP cables contain solid conductors, patch cords are made with stranded conductors because they are more flexible. The flexibility allows them to withstand the abuse of frequent flexing and reconnecting. Although you could build your own field-terminated patch cords, we strongly recommend against it.
At first glance, patch cords may seem like a no-brainer, but they may actually be the most crucial components to accurately specify. When specifying patch cords, you may also require that your patch cords be tested to ensure that they meet the proper transmission-performance standards for their category. Fiber patch cables are used for fiber optic cabling. Usually it is divided into single mode fiber patch cord and multimode fiber patch cord. Single mode fiber operators to a long transmission distance, while multi-mode fiber is a short transmission distance.
Choosing the right cables for your job
Professional cable installed and cable-plant designers are called upon to interpret and/or draft cable specifications to fulfill business' structured-cabling requirements. Anyone purchasing cable for business or home use may also have to make a decision regarding what type of cable to use. Installing inappropriate cable could be unfortunate in the event of a disaster such as a fire.
Cable plant designer can held accountable in court and held responsible for damages incurred as a result of substandard cable installation, Cables comes in a variety of ratings, and many of these rating has to do with how well the cable will fare in a fire.
Using the general overview informations provided here, you should now have adequate information to specify the proper cable for your installation.
First, you must know the installation environment and what the applicable NEC and the local fire-code requirements will allow regarding the cables' flame rating. In a commercial building, this usually comes down to where plenum-rated cables must be installed and where a lower rating is acceptable.
The second decision on cabling must be on media type. The large majority of new installations use fiber optic cable in the backbone and UTP cable for the horizontal.
For fiber optic cable, you will need to specify the fiber type first, single-mode or multimode. If it is multimode, you will need to specify the core diameter. That is 62.5/125 or 50/125. Most new installations use an 850nm, laser-optimized 50/125 multimode fiber, better know to the industry as OM3 fiber. A special fiber patch cable takes multimode ST patch cable for example, it can be either with OM1 62.5/125 types or OM2 50/125, simplex or duplex, connector types of ST-ST, ST-MTRJ, ST-LC, etc. The large majority of new networks use an 850nm, laser-optimized 50/125 multimode fiber, better knows to the industry as OM3 fiber. Of UTP cable, you need to specify the appropriate transmission-performance category. Most newly installations today use Cat6, and there is a growing migration to Cat6A. Make sure that you specify that patch cords are rated in the same or higher category than the horizontal cable.
