GYFTA53 Fiber Loose Tube Armored Cable
Description
The GYFTA53 fiber loose tube armored cable is a self-supporting fiber optic cable which uses a two-layered reinforced armored structure for a better compressive performance. It is mainly used as an outdoor aerial cable. We can provide fiber optic cables whose fiber count ranges from 2 to 144 and can be used for FTTP, main cable, the trunk of power systems and many other occasions.
Standard
The structure of GYFTA53 fiber loose tube armored cable combines a fiber optic with a radius of 250μm inside the loose tube made of high modulus materials. The loose tube is filled with a waterproof compound, and it will strand FRP to form a compact and round cable core. A waterproof filler is added to the gap, and the cable core is then sheathed in a PE inner sheath. The APL is longitudinally wrapped and is extruded with a PVC inner sheath. The double-sided PSP is longitudinally wrapped and sheathed with polyethylene to form a cable.

Features
The GYFTA53 fiber loose tube armored cable has great mechanical behavior and temperature characteristics. The material features a great hydrolysis resistance and higher strength, and a special grease fills the loose tube in order to offer additional critical protection. It also features a great compressive resistance and softness.
The following measures have also been taken to ensure the waterproof performance of the optical cables
- Using the single steel wire as central strength member.
- Filling up the loose tube with special waterproof compound.
- 100% cable core filling
- APL used as a moisture barrier.
- Double-sided PSP improves the moisture resistance of the optical cables.
- Great waterproof materials prevent water from seeping into the cable.
