GYTA Fiber Loose Tube Armored Cable
Description
GYTA fiber loose tube armored cable is a common type of outdoor fiber optic cable. We provide different fiber counts which range from 2 cores to 144 cores. The optical fiber cable can be used for long distance and short distance transportation and can be used as trunk cable. This outdoor fiber cable can be used as outdoor aerial cable and is applied in pipe laying.
Standard
The structure of GYTA fiber loose tube armored cable is to combine the fiber optic whose radius is 250μm inside the loose tube which is made of high modulus materials. And the loose tube is filled with waterproof compound. In the center of the cable core is a metal-strengthening core which is sometimes sheathed with PE for cable with particular fiber cores. The loose tube strands the central strength member to form a compact and round cable core. The waterproof fillers fill up the gap inside the cable core. The APL is longitudinally wrapped and sheathed with polyethylene to form up cable.

- The GYTA fiber loose tube armored cable has great mechanical behavior and temperature characteristics.
- The material of the loose tube has great hydrolysis resistance and higher strength.
- A kind of special grease fills up the loose tube to provide the fiber optic with critical protection.
- The especially designed and close-knit cable structure of GYTA fiber loose tube armored cable can prevent the casing from retracting effectively.
- The PE sheath has great anti-UV radiation performance.
The following measures are adopted to ensure the waterproof performance of the optical cables
- Using single steel wire as the central strength member.
- Filling up the loose tube with special waterproof compound.
- Using double sided PSP to improve the moisture resistance of the optical cables.
