Description
GYTA fibre optic cable is an outdoor communication optical cable of metal strength member of the loose tube jelly-filled structure with Al-polyethylene laminated sheath. The loose tubes are made of high modulus plastics (PBT), which are filled with water resistant filling gel and stranded around a metallic central strength member. Cable core is filled with filling compound. A corrugated aluminum tape is longitudinally applied over the cable core, and extruded with a durable polyethylene (PE) sheath.
Features and Benefits
1, Full cross-section water-blocking structure and double-sided coated film steel belt longitudinal application ensure good water blocking and moisture resistance.
2, Loose tube is filled with special grease to ensure good water blocking and moisture performance
3, The phosphate wire center stiffening member is of high modulus and corrosion resistance. More than 30 years of service life.
4, Applications of GYTA single mode fiber optic cable
5, Long haul and building network communication

| Note: 1. For flame retardant cable, outer sheath can be made of low-smoke halogen-free (LSZH) material, and the type is GYTZA. 2. The outer sheath with longitudinal color strip convenient for identification and maintenance in the one routing can be provided on customer's request. The color can be selected based on customer's request, and bright color (such as yellow, green and red) can be proposed. The GYTZA type is not included. 3. Special cable structure can be designed and manufactured on the customer's request. | ||||||||
