GCYXTY 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 one of the professional optical fibre manufacturing companies, TUOLIMA can customize the optical cable according to your requirements.
Fiber Optic air blown cable is featured with small diameter, lightweight, low friction, excellent softness, and high fiber density, which can improve the laying efficiency and save construction cost.
