GYY Fully dry stranded optical cable

Product Description The structure of the optical cable is to insert single-mode or multi-mode optical fibers into a loose tube made of high modulus plastic. At the center of the cable core is a metal reinforcing member. For some optical cables with certain core numbers, a polyethylene pad layer is extruded outside the metal central reinforcing member. Loose tubes (and filling ropes) are twisted around the central reinforcing piece to form a compact and round cable core. Water-blocking yarns, tapes and other dry water-blocking materials are placed in the gaps of the cable core and inside the sleeve. Tear ropes are pre-embedded and then extruded and wrapped with polyethylene adhesive sheaths to form the cable.

Laying methods: Pipeline, non-self-supporting overhead, etc.

Application scope: Suitable for long-distance communication and inter-office communication, etc.

Execution standard: YD/T 3350.1-2018 Fully dry Outdoor Optical Cable for communication: Stranded type.

Product features:

① The reasonable design and precise control of the excess length of the optical fiber in the loose tube and the cabling method endow the optical cable with excellent mechanical and environmental performance;

② The outside of the reinforcing parts, the inside of the cable core, and the inside of the loose sleeve are all made of water-blocking yarn, tape or other materials in a fully dry water-blocking manner, ensuring the moisture-proof and water-blocking effect of the optical cable. At the same time, there is no grease pollution, it is environmentally friendly, and the optical cable is easy to clean during splicing.

③ The optical cable has excellent flexibility and resistance to bending.
