Optical Fiber Cable (GYTA33) Gel-filled, Double jacket, Steel wire armored

Short Description:

UnitekFiber supply GYTA33 fiber cable. The structure o GYTA33 cable is a metal reinforcing member in the central of the cable and loose tube stranded with waterproof filling compound. The inner jacket is aluminum-polyethylene .The round fine steel wires wrapped around the inner jacket. Then extruded with Polyethylene outer sheath makes the cable have good UV resistance.

Structure

Outdoor optical fiber cable for communication with metal strengthening member, loose tube layer twisted filling type, aluminum-polyethylene bonded sheath, single-layer thin round steel wire armored polyethylene outer sheath.

Application

Application range: long-distance communication and inter-office communication
Laying method: direct burial, underwater
Working temperature: -40～+70℃
Bending radius: static 15 times the cable diameter, dynamic 30 times the cable diameter

Features

1. Full-section water-blocking structure to ensure good water-blocking and moisture-proof performance
2. The loose tube is filled with special ointment for critical protection of the optical fiber
3. Phosphated steel wire central reinforcement member has high modulus and corrosion resistance
4. Longitudinal wrapping double-sided film-coated wrinkled aluminum tape, thin round steel wire wrapping and armoring, to ensure the mechanical compression, tensile and ballistic performance of the optical cable, and meet the application requirements of climbing direct burial and underwater laying.
5. The service life of the product is more than 30 years
