Fiber Optic Cable

What is indoor fiber optic cable?

Fiber optic indoor cabling is the backbone way for the transmission of data around the buildings which is also sometimes referred to armored indoor FO cable. These cables are usually used for the development of level subsystem deep in between the building construction. The most common types of indoor FO cables are GJFJV, GJFJZY, GJFJBV, GJFJBZY, GJFDBV and GJFDBZY. The characteristics of the indoor cables are different from the cables used for outdoor.

Indoor FO cables are very robust and rugged, an important characteristic for indoor cablings. It is ideal for demanding and harsh indoor environment such as conduits, junction boxes and patch panels. Ordinarily they comprise of the accompanying parts inside the cable, the FRP which is non-metallic fortify part, the strong compact optical fiber to increase the durability of the link structure, elevated level of tension, and the cable outer layer jacket. The most common way is to utilize LSZH or other RoHS consistent PVC materials to create a perfect cable outer jacket.

What are some common types of indoor cables?


Multifiber cable holds multiple fibers that is self-sustaining sheathed. One standard configuration usually contains 12 fiber cables and can be either a loose or tight buffered. These cables are effective in carrying unrelated signals that other types of cables are unable to accomplish. 


Simplex fiber optic cable is usually utilized for solely one transmission between multiple devices. It is made of a single strand of durable plastic fiber. Another use of a simplex cable would be when there is a bi-directional data signal transmission. 


Duplex fiber optic cable is commonly used when there is a different duplex communication between multiple devices. This is where there are 2 different transmissions. It is made of double simplex fiber optic cable of sturdy plastic fiber. Instead of using 2 simplex cable, you can use a duplex cable for two transmissions. This is also for aesthetic and for ease of use. It will be easier to handle.


Ribbon fiber optic cable has multiple fibers that is arrange orderly together in one jacket. Is it usually consisting of up to 12 fibers in a single jacket. It is available in both single mode and multimode. Ribbon cable is quite versatile these days where it is applicable for outdoor cables as well as in premises such as cabling and connect devices within cabinets in computer data centers.


Breakout fiber optic cable consists of up to 24 fiber strands. It combines the versatility of many fibers to work with the strength of each jacketed sub-units. Application is commonly used for rugged cross-connects and fiber “backbone”.
