OSP fiber cable is outside plant fiber cable, commonly used for outdoor applications. OPS fiber optical cables are divided into two types: central tube and layer stranded cable.
The structure of central tube fiber cable is a loose tube in the center, and the reinforcing member is located around the loose tube. For example, the common GYXTW type optical cable has a small number of fiber cores, usually less than 12 cores, now can be 24 cores.
Small center tube cable is used abroad a lot. The cable structure is that glass fiber yarn or aramid Kevlar yarn is added to the central PBT loose tube and then sheathed with LSZH or PE. The cable is relatively soft and has a certain pulling strength, which common apply for indoors and outdoors. Overhead and pipeline are relatively convenient.
Stranded fiber optic cable is designed with 5 or 6 of loose tubes stranded around strength member. There are many type of stranded fiber cables, such as GYTS, GYTA, GYFTY, GYTA53, and GYTY53, etc..By combining the loose tubes, the fiber cores of stranded fiber cable can be 24-144cores.
