GYXTY
Unitube Non-armored Cable
Structural features：Central tube cable(also called loose tube cables)
Optical fiber applications place: Overhead laying
Fiber optic cable types：GYXTY
Fiber Numbers:1-12 fibers
Recommended index: 3 stars
Outdoor communication, metal reinforcement member, center tube, fully filled, entrained reinforcement polyethylene sheathed cable.
Description
The fIbers ,250μm，are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound.Over the tube,water-blocking material is applied to keep the cable watertight. Two parallel steel wires are placed at the two sides .The cable is completed with a polyethylene (PE) sheath.
Characteristics
Good mechanical and temperature performance
High strength loose tube that is hydrolysis resistant
Special tube ling compound ensure a critical protection of Two parallel steel wires ensure tensile strength
PE PE sheath protects cable form ultraviolet radiation
Small diameter, light weight and friendly installation
Long delivery length
Standards
Complies with Standard YD/T 769-2010.
