GYTA optical cable refers to loose-tube stranded armored optical cable. It is a type of outdoor optical cable that can be piped or overhead. The structure of GYTA optical cable is to insert single-mode or multi-mode optical fiber into a loose tube made of high-modulus polyester material. The tube is filled with waterproof compound; the loose tube (and filling rope) is twisted around the central strengthening core. Compact round cable core, the gaps in the cable core are filled with water-blocking filler. Plastic coated aluminum strip (APL) is wrapped longitudinally and then extruded with polyethylene sheath to form a cable.

GYTA (Stranded Loose Tube Non-metallic Cable) refers to loose tube layer twisted armored optical cable, a kind of outdoor optical cable, which can be piped or overhead.
The structure of GYTA optical cable is to put single-mode or multi-mode optical fiber into a loose tube made of high-modulus polyester material, and the tube is filled with waterproof compound. The center of the cable core is a metal reinforcing core. For certain core numbers, a layer of polyethylene (PE) needs to be extruded outside the metal reinforcing core. The loose tube (and filler rope) is twisted around the central strengthening core into a compact circular cable core, and the gaps in the cable core are filled with water-blocking filler. Plastic coated aluminum strip (APL) is wrapped longitudinally and then extruded with polyethylene sheath to form a cable.
Product Features
1. Precise control of the excess length of the optical fiber ensures that the optical cable has good tensile properties and temperature characteristics.
2. The loose tube material itself has good water resistance and high strength. The tube is filled with special grease to provide critical protection for the optical fiber and has good pressure resistance and flexibility.
3. PE sheath has good UV radiation resistance and environmental stress cracking resistance.
4. Use the following measures to ensure the waterproof performance of the optical cable:
a) Single steel wire center reinforcement;
b) Loose tube filled with special fiber paste;
c) 100% cable core filling;
d) GYTA double-sided plastic-coated aluminum tape (APL) improves the moisture-proof ability of the optical cable;
e) Good resistance The water material prevents longitudinal water seepage of the optical cable.
Characteristics of GYTA and GYTS optical cables
1. Inner steel and inner aluminum extend the service life of the optical cable. GYTS optical cable is an overhead and directly buried optical cable, and GYTA optical cable is an optical cable that is aerial and passes through underground pipes.
The following figure shows the cross-section of GYTS and GYTA:
##2. GYTS optical cable is divided into multi-mode and single-mode Two models. The broadband of GYTS optical cable not only has high transmission speed, but also has good confidentiality, strong anti-interference ability, good insulation and long life. S stands for steel strip, which can withstand strong tensile force, and A stands for aluminum strip, which is a good raw material for moisture resistance. In real life, there are steel wire ropes on the optical cables as load-bearing parts, and the optical cable itself does not use much tension. Optical cables are often used as communication tools and conductors for broadband and Internet networks in daily life. Common optical fiber:According to the classification of different optical fibers, the same optical fiber will have different names;You can press Classification of optical fiber manufacturing materials; Optical fiber types can be divided into quartz optical fiber and all-plastic optical fiber.
