GYFTA54 Anti-rodent and Anti-termite Optical Cable with Double Metallic Armors and Nylon Sheath

GL Fiber provides types of biological protection(Anti-Rodent, Anti-Termite, Anti-Birds) optical fiber cables, This type optical cables resistant to biological hazards caused by rodents, termites and birds, etc., after installation. Rodents often damage optical cables. Termites not only bite but also release formic acid to the cables. Our design methods include physical(including metallic and glass fiber armor and nylon sheath) and chemical (Spicy additives ) against biological hazards.

Cable Section Design:

Features:

• Accurate process control ensuring good mechanical and temperature performances
• The material of loose tubes with good hydrolysis resistance and relatively high strength
• Tube filling compound providing key protection for fibres
• Excellent crush resistance
• Metallic armors providing good anti-rodent performance
• Nylon outer sheath with high hardness providing certain anti-termite performance
• Applicable to duct and buried installations
