FS Fiber Optic Cable Types

To date, fiber optic cables have brought high speed network services to companies, campuses and homes. And we have discussed fiber optic cables a lot in the past, such as Introduction of Fiber Optic Cable. However, the truth is we have just scratched the surface of this complicated system. Different fiber optic cable types are versatile in the function and installation. Today, we’ll introduce FS fiber optic cable types in order to further understand the optic cables.

Why Fibers?

Fibers are truly one of the greatest inventions of our world. They are slim cables that have thousands of optic fibers within the plastic, outer jacket. The optic fibers are incredibly hair-thin strands of glass that transmit data by light, which is quite different from the copper cables or RJ45 cables. Basically, compared with the copper cables, fiber cables are much more efficient and secure for network applications. They can deliver more data with a greater degree of fidelity over greater distances. In addition, because fiber cables are made of glasses, they are immune to any type of electrical interference. Therefore, these cables could be put in direct contact with soil or in close proximity to chemicals without concern.

FS Fiber Optic Cable Types

To make a clear product catalog, FS has classified the fiber cables by different applications. Therefore, people can select the cables more easily according to their various needs.

MTP/MPO Fiber Cable

MTP/MPO fiber cables consist of MTP/MPO connectors and fiber cables. Each cable can bring 8, 12 or 24 fibers together in a single MTP/MPO interface. And other connectors like SC or LC are also could be found in some MTP/MPO cables. MTP/MPO cables are designed for 40 or 100G applications in data centers for ultra-high density cabling. FS MTP/MPO cables have low insertion loss, and help you reach direct connection for 40G connectivity. As the figure shows, MTP/MPO cable is usually used for connecting optic transceivers, MTP cassettes and fiber adapter panels and so on.

Fiber Patch Cables

Usually, fiber patch cables are terminated with fiber optic connectors such as LC, SC, ST and so on at each end of the cables. Through these connectors, optical cables can be connected to network switches, patch panels or other networking devices. Based on fiber cable mode, fiber patch cables are divided into single mode fiber like OS2, and multimode fiber such as OM3 and OM4. All FS fiber patch cables are made of PVC jacket material with low insertion loss and attenuation at different distances. They play important roles for indoor uses like server rooms. Commonly, fiber patch cables are used to connect transceiver modules. Note that, fiber cables with different connectors must be connected with the transceivers that have the corresponding interfaces. For example, the following cable is a LC to LC single mode cable. Therefore, the transceivers here must have LC interfaces.

Ultra HD Fiber Cables

In FS ultra HD fiber cables catalog, there are ultra low loss LC SMF/MMF, uniboot LC cables, BIF fiber cables and customized LC+ cables. Compared with traditional fiber cables, ultra HD fiber cables use a compact design with a flat clip model and a slimmer wire body, which saves about 50% of cabling space. This is extremely suitable for high density data centers.

LC-LC Patch Cable in Data Center

LC-LC patch cable has already become the main force of high density cabling network infrastructure. To future increase the profits of LC-LC fiber patch cable, manufactures has invented LC-LC patch cables of different features to meet various requirements in data center and increase the network performance.

What Kind of Fiber Patch Cable Is Required in Data Center?

Data center is a place of thousands fiber links. The selection of fiber patch cables will directly affect the network performance. More and more data centers choose to select fiber patch cable of high performance. Generally, insertion loss and return loss of connectors terminated on patch cable and light loss of optical fiber used for fiber patch cable are three most basic factors for fiber patch cable selection. To satisfy the increasing demands for higher density and easier management in data center, the optimization of fiber patch cable has never stopped. The following introduces several popular LC-LC fiber patch cables which represent the trends of fiber patch cable that data center is asking for.

LC-LC fiber patch cable

Low Insertion Loss and Bend Loss LC-LC Patch Cable

When a length of fiber patch cable is connected in network, optical light loss occurs at the optical fiber and the connectors terminated on it. There are different optical light losses, among which insertion loss at the connectors and bend loss in fiber optic cables are the two most commonly light losses that technicians are trying to overcome. Manufactures provides LC-LC fiber patch cables which can minimize these losses to the most.

Insertion loss refers to the fiber optic light loss caused when a fiber optic component insert into another one to form the fiber optic link. To provide low insertion loss patch cable, LC connectors terminated on the patch cable has been optimized. Standard LC-LC patch cable usually has an insertion loss less than 0.3 dB. However, for upgraded LC-LC patch cable, the insertion loss is usually lower than 0.2 dB. To decrease the bend loss, a type of bend insensitive fiber (BIF) has been used in fiber patch cable. With optimized LC connectors and bend insensitive fiber, LC-LC fiber patch cable could provide lower light loss during network transmission.

uniboot LC cable

High Density LC-LC Patch Cable

LC connector was invented for higher cabling density. standard duplex LC-LC fiber patch cable can provide much higher cabling density than other duplex fiber patch cables. To further increase cabling density in data center, the connectors and cable diameter of LC-LC patch cable are becoming smaller. Uniboot LC-LC patch cable is a typical example. This kind of fiber patch cable designed the two fibers of the duplex patch cable into a single cable. In adding the two connectors terminated at each end of the duplex patch cable share the same boot. With less using cable counts, uniboot patch cable can provide higher cabling density and better cooling environment in data center.

Polarity Switchable LC-LC Patch Cable

The development of patch cable won’t stop at low loss and high density. Making fiber patch cable easier-to-use is also important. Polarity of fiber patch cable matters a lot during installation of fiber patch cable, especially for duplex fiber patch cable and MTP patch cable. It is common to change the polarity of a duplex patch cable during deployment. Technicians might need tools to change the polarity of patch cable. However, a polarity switchable LC-LC patch cable can make things much easier. Without any tools you can polarity reversal could be really easy. The following picture shows the polarity reversal of a special designed LC-LC patch cable.

polarity switchable LC patch cable

Conclusion

LC-LC patch cable has been designed into many different types. A high performance fiber patch cable should not only provide low insertion loss and bend loss, but also higher cabling density and easy-to-use features. This is also the trend of data center development.

Which Tight Buffered Fiber Distribution Cable Fits Your Application?

Optical fibers with fiber counts ranging from 2 to 144 counts or more are usually coated together inside a single strand of fiber optic cable for better protection and cabling. Multi-fiber optic cables are usually required to pass a lot of distribution points. And each individual optical fiber should connect only one specific optical interface via splicing or terminating by connectors. Thus, fiber optic cables used for distribution should be durable and easy to be terminated. Tight buffered fiber distribution cables, which meet these demands, are widely used in today’s indoor and outdoor applications, like data center and FTTH projects. This post will introduce tight buffered fiber distribution cables.

The Beauty of 900um Tight Buffered Fibers

Most of tight buffered fiber distribution cables are designed with 900um tight buffered fibers. This is decided by its applications. As the above mentioned, the distribution cable should be durable and easy to be terminated. The following picture shows the difference between 250um bare fiber and 900um tight buffered fiber. They are alike, but the tight buffered fiber has an additional buffer layer. Compared with bare fibers, 900um tight buffered fibers can provide better protection for the fiber cores. 900um tight buffered fibers are easy to be stripped for splicing and termination. In addition, tight buffered fiber cables are usually small in package and flexible during cabling. These are the main reasons why a lot of fiber optic distribution cables use tight buffered design.

Choose Tight Buffered Distribution Fiber Cables According to Applications

900nm tight buffered distribution fiber cables also come in a variety of types. Tight buffered distribution fiber cables used for different environments and applications might have different fiber types, outer jackets and cable structures. The following will introduce several tight buffered distribution fiber cables for your reference.

unitized distribution fiber cable
Indoor Tight Buffered Distribution Fiber Cable

Tight buffered distribution fiber cables used for indoor applications are usually used for intra building backbones and routing between telecommunication rooms. Large tight buffered fiber cable with fiber counts more than 36 fibers generally has “sub-unit” (unitized) design (shown in the above). While smaller tight buffered distribution cables, with fiber counts of 6, 12 or 24, usually have “single-jacket” (non-unitized) designs, which are more flexible in cabling and have much smaller packages and cost advantages. The lower count tight buffered distribution fiber cables with color coded 12 fibers and 24 fibers are very popular. The following picture shows a 24-fiber indoor tight buffered distribution fiber cable with single-jacket design.

24-fiber tight buffered fiber cable

During practical use, these 6, 12 or 24-fiber indoor tight buffered distribution fiber cables can be spliced with other fibers or be terminated with fiber optic connectors. And they can be made into multi-fiber optic pigtails or fiber patch cable after terminated with fiber optic connector on one end or two end. The color coded fibers can also ease fiber cabling.

Indoor/Outdoor Armored Tight Buffered Distribtight buffered fiber terminationution Fiber Cable

Although tight buffered distribution fiber cables are usually used for indoor applications, there is still a place for them in outdoor applications after added with a layer of metal armored tube inside the cable. Armored fiber cables are durable, rodent-proof, water proof and can be directly buried underground during installation, which saves a lot of time and money.

Armored tight buffered distribution fiber cable

Here we strongly recommend a low fiber count armored tight buffered distribution fiber cable which can be used for both indoor and outdoor applications (show in the above picture). This low fiber count armored tight buffered cable has a single-jacket design with a steel armored tape inside the cable. It can be used for both backbone cabling and horizontal cabling in indoor environments. And it can also be used for direct buried applications and aerial application in outdoor environments.

Which Armored Fiber Cable Should I Choose?

Armored fiber cable with build-in metal armor can provide stronger protection of the optical fibers than standards fiber optic cables. It can protect the optical fibers from rodent, oil, impact, etc. What’s more, some armored fiber can provide maximum bend radius. However, various types of armored fiber cables usually make customers confused. There are too many specific details to consider during selection, like fiber counts, jacket type, structure of the armored fiber cable, etc. This post is offering the details about how to select the right armored fiber cable.

Structure and Application of Armored Fiber Cable

Structures of armored fiber optic cables come in a variety of types according to different applications. There are mainly three types of armored fiber cable: indoor armored fiber cable, outdoor armored fiber cable and indoor/outdoor armored fiber cable. Each of the three armored fiber cables has various subcategories. The structures of the three types of armored fiber optic cable are different from each other. Here takes the example of an indoor light armored fiber cable to introduce the basic structure of armored fiber cables.

armored fiber cable structure

As shown in the above picture, the optical fibers of the armored fiber cable are in the center of the cable covered by metal armor. The metal armor is covered by Kevlar firstly, then by the outer jacket. This is usually the most basic structure of armored fiber cables. For different applications, the structure will change accordingly. Watch the video below to get more details about the basic structure of armored fiber cable and where they are used.

How to Select Armored Fiber Cable?

The selecting of armored fiber optic cable is like the selection of standard fiber cables. Fiber type (OS2, OM1, OM2, OM3, or OM4), fiber count and cable riser should all be considered. However, there is many special properties of armored fiber optic cable, the armored fiber cable selection should also consider many other factors.

interlock armor and corrugated armor
Armor Type of Armored Fiber Cables

The market can provide armored fiber cables with different types of armor tubes which are with different structures and materials. The most commonly used armor tubes are with interlock design and corrugated design as shown in the above picture. For now, the interlock armored fiber cable is very popular and being used in a lot of indoor and indoor/outdoor applications. Corrugated armored fiber cable is often used in outdoor applications. As for the materiel for armor tube, steel and aluminum are the most commonly used. Now light steel armored fiber cables are being widely used in a lot of indoor applications, because of its lower weight and flexible properties.

pre-terminated armored fiber cable
Pre-Terminated or Field-Terminated Armored Fiber Cables

As there is a strong metal armored tube inside the armored fiber cable, the termination of armored fiber cable is difficult than that of standard fiber optic cables. In some applications, field-terminated armored fiber cable is better in outdoor applications. While, to save time and ensure transmission quality, many installers will choose pre-terminated armored fiber cables for indoor applications. The pre-terminated armored fiber cables provided by the market are mainly armored fiber patch cable and armored fiber trunk cable. The former looks like the standard fiber patch cable, but it is stronger than the traditional fiber patch cable and is more flexible during cable for it can provide larger bend radius. Pre-terminated armored fiber trunk cable is a length of armored fiber cable with several legs on each ends terminated with fiber optic connectors.

Conclusion

Armored fiber cable is a cost-effective solution for fiber optic link protection. During the selection of the armored fiber cable, except fiber count, fiber type and cable riser, the armored type, cable structure and termination types should also be considered.

Fiber Patch Cables for Harsh Environment

It is usually inevitable to deploy fiber cables in harsh environments for both indoor and outdoor applications. Rodents, like squirrels in outdoor and rats in data centers, are cable destroyers which like to bite or chew fiber optic cables. Except that, there are also many other challenges which can harm fiber optic cables and cause fiber failures, like dusts, water or other liquid, accidental impact, etc. Thus, enough protection should be provided for fiber optic network. Two types of fiber patch cables, which are specially designed for harsh cabling environments, will be introduced in this post.

The two fiber patch cables are armored fiber patch cable and IP67 fiber patch cable. As most fiber cable failures are usually caused by fiber breaks and contaminants, the fiber cable and the termination points of the fiber links should all be well protected. And the two types of fiber cable can perfectly meet most requirements of harsh cabling environment.

Unlike traditional fiber patch cables which are fragile and usually need careful operation, armored fiber patch cables are usually much more durable and flexible. Armored fiber patch cable usually has two jackets, one inner jacket and one outer jacket, between which there is a build-in steel tube. Some vendors also provide armored fiber cables with aluminum tube. This robust metal tube can provide optical fibers inside armored fiber cable from the impact and bite from animals. The most commonly used designs of armor used in armored fiber cables are interlock and corrugated. For most outside plant applications, the corrugated armored fiber cables are suggested. Now a lot of armored fiber patch cable uses interlock armor. During operation in data center, armored fiber patch cable can provide a more flexible cabling environment, because it has bend restrictor which can provide optical fibers from over bending. The following picture shows the structure of an armored fiber patch cable.

IP67 fiber patch cable is a robust fiber patch cable terminated with specially designed fiber optic connections, which can protection fiber links from the harm of dusts and liquid. “IP67” is the code of Ingress Protection Marking which is a system to provide the protection level of products. The former digit “6” (totally protected against dust) and the latter digit “7” (protection from water dip) is used to describe the protection degrees of dust and liquid separately. The highest level of a fiber patch cable that can be provided in the market is IP68. IP67 fiber patch cable is an ideal solution to protect fiber links, especially the termination points. The fiber connector terminated on the IP67 fiber patch cable is different from traditional ones. A standard fiber optic connector is being protected by a special shell. To connect two IP67 fiber patch cables, special fiber optic adapter should be used for better sealing and protection. The following picture shows a LC-LC fiber patch cable. The following table listed part of the most commonly used IP67 assemblies.

Conclusion

Fiber cable protection is always the priority of fiber optic networks. Selecting the right patch cable according to applications is essential and necessary. For environments where animals and impact are very common, armored fiber patch cable can be used. For places where liquid and dusts are great challenges, waterproof IP67 fiber patch cable, proving great sealing, is suggested.
