GYTA Outdoor Optical Cable

GYTA Outdoor Optical Cable
Number: GYTA
  • Product introduction

Application:                                    
Laying method: Duct/Aerial
Suitable for long-distance trunk and LAN communication.
Fiber type: Single-mode/Multimode
Characteristics:
LAP Aluminum belt is applied around the cable core, which is filled with the filling compound to protect it from water-ingress.
Accurate fiber excess length ensures good mechanical and temperature performance.
Specially designed compact structure is good at preventing loose tubes from shrinking.
High strength loose tube that is hydrolysis resistant and special tube filling compound ensure a citical protection of fiber.
Moistureproof and ratproof.
