The glass yarns are soft in texture and can well cover and protect the tight-fitting fiber. At the same time, the glass yarns have the advantages of light weight, high tensile strength, slow heat transfer, and good resistance to instantaneous ultra-high temperature. They play a certain tensile and delayed heat conduction role, and can better protect the internal tight-fitting fiber. When the organisms chew the glass yarns, the capillary glass fibers cause stinging in their mouths, preventing them from further damage, which can greatly play a biological protection role. On the other hand, the flat glass fiber sheet is arranged around the outer layer of the glass fiber belt, which plays the role of non-metallic armor, can improve the tensile and lateral pressure resistance of the optical cable, and prevent biological damage such as rodents chewing, birds pecking, and insects and ants biting, which can play the first layer of protection.
