Description

Technical Field

[0001] The utility model relates to the technical field of optical cable foam, in particular to a corrosion-resistant high-strength optical cable. Background Art

[0002] Optical cable is a cable used to transmit optical signals, usually composed of one or more optical fibers. Optical fiber is a thin glass or plastic fiber that can transmit optical signals along the inside of the fiber. Corrosion-resistant high-strength optical cable usually refers to optical fiber communication cables made of special materials and designs. This type of optical cable has the characteristics of strong corrosion resistance and high tensile strength. Usually, the outer sheath is made of polyethylene material, which can improve the corrosion resistance and wear resistance of the outer sheath to a certain extent.

[0003] However, it still has the following disadvantages in actual use:

[0004] The optical cable joints need to be wrapped with tape. This wrapping method has two disadvantages: one is that the wrapping is uneven, which affects the appearance; the other is that the protection is insufficient, the durability is poor, materials are wasted, and it is difficult to maintain again.

[0005] Therefore, a new corrosion-resistant high-strength optical cable is proposed to solve the above problems. Utility Model Content
