Features:
Select quality fiber to ensure excellent transmission performance
Adopt strict process and raw materials control to guarantee the lifespan of 15 years
Good uniformity of the diameter of buffer fiber and excellent strip ability.
Good performance of flame-retardant. Small bending radius.
Excellent mechanical and environmental performance.
Colored bare fiber is available
