GCYFXTY Air Blown Fiber Optic Cable

GCYFXTY Air Blown Fiber Optic Cable


GCYFXTY Air Blown Cable is a loose tube made of a high modulus material with a 250µm single-mode or multi-mode fiber. 


The tube is filled with a non-toxic and harmless waterproof compound, and the loose tube is twisted with a non-metallic reinforcing element. Then extruded black or colored high-density polyethylene (HDPE) sheath into cable.


As a professional fiber optic manufacturer, we have different types of optical fibre for our customers.
