1. Good mechanical and environmental characteristics

2. The strippability characteristics of buffer meet the customer requirements

3. Meet various requirements of market and clients




1. Tight-buffered fiber is the basic element of various indoor cables. Different buffer materials can meet different mechanical and environmental requirements, such as large tensile (crush), high or low temperature, frequent bends, low smoke, no corrosive, field use, distribution cabinet (frame) and other generic use.

2. Tight-buffered fibers can also be used in pigtails, optical connections of various active and passive devices, instruments and terminal units.
