FAQ In Fiber Optic Cabling


Firstly, do choose multimode or single mode fiber? What is the difference between them?

In general, the user requests the fiber transmission distance is relatively short, such as a few hundred meters, can be Multimode Fiber Optic Cable. However, if the transmission distance has several kilometers, even further, without the use of signal repeaters must be single-mode fiber.

Secondly,  Do choose 4 core, 6 core, 8 core or more core Fiber Optic Patch Cables?

Fiber complete the transfer task, it must receive at least one first serve two core. In fact, there are 4,6,8 or more optical fiber core, the core can be used as extra backup, you can do more transmission channels.

Thirdly,  Does use wall or rack-mounted fiber optic patch panel cable box?

Wall fiber boxes are generally used in small fiber-optic network, for example, a 4-core optical fiber, but if there is more number of fiber optic, it shows the advantages of rack patch panel. It can be placed inside the routers and switches with a cabinet for easy centralized management and more secure.

And then, What is the connector type of FC,SC,ST,LC,MTRJ, and Which one can be choose?

These different interfaces have used in different environments, they differ mainly in the method and shape connection, is it the same as the screws tighten or direct card? Is square or round? Large or small mouth opening (mouth relatively large place occupied by a small mouth can have greater port density)? Two heads separately or synthetic one? Users need not be too concerned about the specific interface, to note that if the extension already exists in the case of older fiber optic systems, you have to match each job.

Finally, Is the choice of the center beam tube or Stranded cable?

Central tube Fiber Optic Cable placed in the center portion of the cable core, many of the core tube synthesis bunch shape, and the outer cable surrounding two wires placed in parallel to ensure tensile strength.

The central part of Stranded cable strengthen stereotypes core fiber. Fiber core surrounded by a peripheral that strengthen the core, many cores together to form the shape layer by layer.

How to identify fiber optic, is single mode or multimode fiber?

The first is a relatively simple method for indoor fiber, it can be identified by single-mode fiber and multimode fiber external color, Single Mode Fiber Cable is yellow, Multimode Fiber Optic Cable is red. Including Fiber optic patch cords and Fiber pigtails are the same recognition.

For MPO Fiber, generally can be identified by model code, there are a bunch of characters on the cable sheath, such GYXTW-4-A1a, the last paragraph begins with A on behalf of the multi-mode fiber, beginning with B represents a multi-mode fiber, a little more detail, A1a representing 50/125 multimode fiber specifications, A1b representatives 62.5/125 multimode fiber specifications, B1.1 representatives of non-dispersion shifted single-mode fiber and so on.

If this way can not be identified single mode fiber or multimode fiber, it is only through a special device to identify, as fiber splicing machine, it will automatically recognize the single mode or multimode fiber, single mode will show SM, multi-mode will show MM.
