Central Tube Fiber Cable Outdoor Fiber Optic Cable

Central Tube Fiber Optic Cable Single Mode/Multimode Outdoor Fiber Optic Cable Application

Optical Fiber Central Tube Cable is mainly used for outdoor fiber connection along with building backbone application networks and link bridges.

Inside the central tube cable, 250µm (singlemode or multimode) fibers are positioned in loose tubes made of high modulus polyester material.

The tubes, filled with water-resistant compounds, are wrapped double chromium-plated PSP armor. Between the armor and the tubes, water-blocking material is applied to keep the cable watertight. Two parallel steel wires are placed at the two sides of the cable core and then a polyethylene (PE) jacket is extruded over it.

Product Features

• Central tube structure is designed for excellent mechanical performance and temperature performance;
• The loose tube material has good resistance to hydrolysis performance and high strength;
• The cable has 62.5/125 singlemode/multimode, 50/125 multimode, 2-24 cores, and many other specifications available;
• It provides a high crush resistance coupled with excellent bending performance and flexibility so as to avoid the impact from the outside environments;
• Its PSP armor improves moisture resistance;
• The two parallel steel wires ensures the cable's tensile strength;
• The cable meets the industry-regulated requirements of optical transmission, mechanical protection and flammability.

Application Standards

YD/T 769; IEC 60793; ISO/IEC11801
