China Glass Yarn for Optical Cables - Leading Suppliers & Factory for Enhanced Protection and Durability
Product Introduction
Protect Internal Structure: The glass sheath completely covers the first sheath, effectively protecting the internal structure of the optical cable from damage.
Anti-Rodent Protection: Glass gauze prevents or reduces squirrels from biting optical cables. Even if the outer skin is bitten through, it prevents further damage and provides additional protection.
Improve Cable Strength: High-strength glass fiber material offers excellent anti-rat bite effects, significantly improving the durability and overall lifespan of the cable.
Safe & Soft Handling: The surface is attached with a layer of soft PU adhesive film. It has good tensile performance, is not easy to break, and ensures processing does not hurt the human body.
