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 filled with waterproof compound. The center of the cable core is a metal reinforcing component. For some optical cables with certain core numbers, a polyethylene pad layer is extruded outside the metal central reinforcing component. Loose tubes (and filling ropes) are twisted around the central reinforcing member to form a compact and round cable core. The gaps inside the cable core are filled with water-blocking compound, and a steel-polyethylene bonded sheath is extruded outside to form the cable.

Pipeline, non-self-supporting overhead, etc.

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

YD/T 901-2018 Outdoor optical cable for stranded communication.

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 and the inside of the cable core are filled with water-blocking cable paste, ensuring the moisture-proof and water-blocking effects of the optical cable.
3. The optical cable has excellent flexibility and resistance to bending.
4. The steel tape longitudinally wrapped around the cable core makes the optical cable have a better moisture-proof effect, and at the same time, it has certain compressive resistance and the ability to prevent damage from rodents.
