GYTA53+33 Armored Fiber Optic Cable
Description
The GYTA53+33 armored fiber optic cable is a kind of outdoor fiber optic cable. It has steel wire armor and PE outer sheath. It can be used under of direct burial, underwater or crossing bodies of water. Ingo can provide different fiber counts ranging from 2 cores to 36 cores. The attenuation and bandwidth of the fiber optic cable is respectively 1.0dB and 1000MHz.km while it is transmitting at the wavelength of 1300nm.
Standard
The structure of GYTA53+33 armored fiber optic cable a combination of fiber optics with a radius of 250μm inside a loose tube made of high modulus materials. The loose tube is filled with a waterproof compound and in the center of the cable core is a metal strengthening core. The loose tube and fillers are stranded around the central strength member to form a compact, round cable core, with the gap then being filled with a waterproof filler. The APL is longitudinally wrapped and extruded with a PVC inner sheath. The double-sided PSP is longitudinally wrapped and extruded with a PVC outer sheath. After being armored with single steel wire, a PVC outer jacket is extruded to form a cable.

Features
The GYTA53+33 armored fiber optic cable has great mechanical behavior and temperature characteristics, and the single steel wire armor gives the cable a better tensile strength. The loose tube material has a great hydrolysis resistance and a relatively high strength. A special grease fills the loose tube and offers additional critical protection. The cable 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.
