Figure 8 Optical Fiber Cable
The structure of the GYTC8A optical cable is to insert a 250µm optical fiber into a loose tube made of high modulus material, and the loose tube is filled with a waterproof compound. The center of the cable core is a metal reinforcing core, around which loose tubes (and filler ropes) are twisted into a compact and round cable core. The cable core is longitudinally wrapped with a layer of plastic-coated aluminum tape (APL), and the steel wire strands are integrated into an 8-shaped polyethylene sheath. YOFC Optical Fiber and Cable Co., Ltd. can also provide Y-sheathed or S-sheathed figure-8 optical cables GYTC8Y, GYTC8S, etc. These products are mostly used in self-supporting overhead laying.
• Steel wire strands have extremely high tensile strength, which facilitates self-supporting overhead laying and reduces installation costs.
• Optical cables have 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 provide critical protection for the optical fiber
• Take the following measures to ensure the waterproof performance of fiber optic cables:
- Single steel wire center reinforcement core
- The loose tube is filled with special waterproof compound
- Complete cable core filling
- Plastic coated aluminum strip (APL) moisture barrier
