Frequently Asked Questions (FAQ)
What is the main function of the glass fiber in the optical cable?
The glass sheath completely covers the first sheath, effectively protecting the internal structure of the optical cable from various types of damage.
Can this optical cable prevent squirrel and rodent bites?
Yes, the glass gauze can prevent or reduce squirrels from biting the cables. Even if the outer skin is bitten through, the glass gauze provides additional protection and prevents the rat from biting further.
Does the glass fiber improve the overall strength of the cable?
Yes, the high-strength glass fiber material provides excellent anti-rat bite effects while significantly improving the overall durability and life of the cable.
What models of glass fiber are currently available?
The available models are 300D, 600D, 785D, and 1200D. These are divided into ordinary glass fiber and water-resistant glass fiber, which can be selected based on your actual requirements.
Is the optical cable safe to handle during processing?
Yes, the surface is attached with a layer of soft PU adhesive film which has good tensile performance, is not easy to break, and ensures that the optical cable processing does not hurt the human body.
What are the standard paper tube sizes available?
Standard sizes include an Inner Diameter (ID) ranging from 54mm up to 127mm, an Outer Diameter (OD) of max 270mm, lengths ranging from 170mm to 270mm, and a yarn height traverse of 150mm to 250mm. Some parameters can also be customized.
