Specification

Applications

1. Tight-buffered fiber is the basic element of various indoor cables. Because of different buffer materials, the relevant indoor cables made out of tight-buffered fibers can meet different mechanical and environmental requirements, for example, large tensile(crush,hight or low temperature, frequent bends,low smoke,no corrosive,environmental,field use, distribution cabinet(frame) and other generic use,etc:
2. Tight-buffered fibers with various buffer material can also be used in pigtails, optical connections of various optical active and passive devices, instruments and terminal units.

 

Features

1. Good mechanical and environmental properties;
2. The strippalility characteristic of buffer meet the relevant standards or customer requirements;
3. Meet various requirements of market and clients.
