Description

Technical Field

[0001] The utility model relates to the technical field of central tube type optical cables, in particular to a central tube type optical cable that is resistant to rat gnawing. Background Art

[0002] Outdoor communication optical cables are generally categorized as stranded, central bundle, and skeleton types. According to YD / T769-2010, central bundle cables consist of a loose tube in the center, a reinforcement member outside the loose tube, and a sheath layer outside the reinforcement member. The loose tube contains multiple optical fibers.

[0003] Loose tube optical cables are designed without a grease filling in the core. Instead of the grease found in traditional loose tube cables, a foamed thermoplastic elastomer acts as a water barrier. These cables can be reduced in size while maintaining mechanical properties, or maintained in size while improving mechanical properties. Eliminating the grease greatly facilitates cable end preparation and splicing, and is also environmentally friendly. This type of cable was developed by Ericsson Network Technologies of Sweden, which trial-produced cables for aerial, duct, and direct burial applications. The results of these cables' structural and performance tests are reported.

[0004] When existing central tube optical fibers are used underground, in order to improve the protection of the cable core, it is necessary to increase the strength and wear resistance of the sheath to prevent damage to the cable core caused by damage to the sheath during long-term use. Therefore, a rat-resistant central tube optical cable is proposed to solve the above problem. Utility Model Content

[0005] In response to the deficiencies in the prior art, the utility model provides a rat-resistant central tube optical cable, which has the advantages of achieving the purpose of preventing rat bites by arranging a protective sheath on the outer surface of the central tube optical cable.

[0009] Furthermore, a splicing plate is fixedly connected to the front of the protective net, a base is provided at the bottom of the protective net, and a support plate is fixedly connected to the top of the base.

Then, several protective cones are clamped into the inside of the mounting seat through the clamping block to prevent rats from gnawing the optical cable when approaching.
