Description

Technical Field

[0001] The utility model relates to the field of optical cables, and in particular to an optical cable with corrosion resistance. Background Art

[0002] In the field of modern communications, optical cables are an important carrier of information transmission, and their performance and reliability are of vital importance. However, existing optical cable technology has some shortcomings.

[0003] Traditional optical cables have poor corrosion resistance. In corrosive environments, such as chemical plants and coastal areas, optical cables are easily corroded by chemicals, causing damage to the cable sheath, which in turn affects the performance of the internal optical fibers and reduces the quality and stability of signal transmission.

[0004] Furthermore, the mechanical protection of existing optical cables needs to be improved. During installation and use, optical cables may be subjected to mechanical forces such as stretching, squeezing, and abrasion, which can easily damage the optical fibers and affect normal communications.

[0005] At the same time, waterproof and moisture-proof performance is also a weak link in existing optical cables. The intrusion of water and moisture can affect the optical fibers inside the cable, increase signal attenuation, and even cause communication interruption.

[0006] In addition, the structural strength of traditional optical cables may not be sufficient to cope with some special application scenarios, such as those that need to withstand large tension or pressure.

[0007] Moreover, in high-temperature environments, the performance of existing optical cables may be affected, and stable signal transmission cannot be guaranteed. Therefore, we have made improvements to this and proposed a corrosion-resistant optical cable. Utility Model Content
