High-Quality Glass Yarn for Optical Cables - Reliable China Supplier and Factory for Durable Protection
Product Introduction
Protect Internal Structure
The glass sheath completely covers the first sheath, effectively protecting the internal structure of the optical cable from damage.
Prevent Squirrel Bites
Glass gauze can prevent or reduce squirrels from biting optical cables. Even if the outer skin is bitten through, the glass gauze prevents further biting and provides additional protection.
Improve Cable Strength
High-strength glass fiber material makes the cable's anti-rat bite effect excellent, significantly improving the durability and life of the cable.
Safe Handling
The surface is attached with a layer of soft PU adhesive film, showing good tensile performance. It is not easy to break, and the optical cable processing does not hurt the human body.
Note: At present, the model of glass fiber is 300D / 600D / 785D / 1200D, which is divided into ordinary glass fiber and water-resistant glass fiber, which can be selected according to the actual situation.

Frequently Asked Questions
What is the main function of the glass fiber in the optical cable?
The glass sheath completely covers the first sheath, which effectively protects the internal structure of the optical cable from damage and improves its overall lifespan.
Can this product prevent animals like squirrels from biting the cables?
Yes, the glass gauze is highly effective at preventing or reducing squirrel bites. Even if the outer skin is penetrated, the glass gauze stops further damage.
Is the optical cable safe for human handling during processing?
Absolutely. The surface is coated with a soft PU adhesive film that provides good tensile performance, prevents easy breaking, and ensures it does not hurt the human body during handling.
What models and types of glass fiber are currently available?
We currently offer models in 300D, 600D, 785D, and 1200D. These are further divided into ordinary glass fiber and water-resistant glass fiber to suit different environmental needs.
What are the available dimensions for the paper tubes?
The Inner Diameter (ID) ranges from 54mm to 127mm, and the Outer Diameter (OD) is up to 270mm. Lengths range from 170mm to 270mm, and traverses from 150mm to 250mm.
Are the product parameters customizable?
