(GYTC8A)8-shaped optical cable

The structure of GYTC8A optical cable is that 250μm optical fiber is sheathed in a loose tube made of high modulus material, and the loose tube is filled with waterproof compound. The center of the cable core is a metal reinforcement core, and loose tubes (and filler ropes) are twisted around the center reinforcement core to form a compact and round cable core. The cable core is longitudinally wrapped with a layer of plastic-coated aluminum tape (APL) and integrated with a steel strand into an 8-shaped polyethylene sheath . YOFC Fiber Optic Cable Co., Ltd. can also provide Y-sheathed or S-sheathed 8-shaped optical cables GYTC8Y, GYTC8S, etc. These products are mostly used in self-supporting overhead laying.

The cable core is longitudinally wrapped with a layer of plastic-coated aluminum tape (APL) and integrated with a steel strand into an 8-shaped polyethylene sheath . Hunan Feibo guangtong communication equipment Co., Ltd. can also provide Y-sheathed or S-sheathed 8-shaped optical cables GYTC8Y, GYTC8S, etc. These products are mostly used in self-supporting overhead laying.
 
 
 
Product Standards
 
GYTC8A optical cable complies with YD / T 1155 and IEC 60794-1 standards.
 
 
 
Features
 
• Steel wire strands have extremely high tensile strength, which facilitates self-supporting overhead laying and reduces installation costs
 
• Optical cable has good mechanical properties and temperature characteristics
 
• The loose tube material itself has good hydrolysis resistance and high strength
 
• The tube is filled with special grease to protect the optical fiber critically
 
• Use the following measures to ensure the waterproof performance of the optical cable:
 
-Single steel wire center reinforced core
 
-Loose casing filled with special waterproof compound
 
-Complete cable core filling
 
-Moisture-proof layer of plastic coated aluminum tape (APL)
