[0002] Optical cable is the most basic carrier medium for optical fiber communication. There are three main ways to lay optical cable communication lines: overhead laying, pipeline laying, and direct burial laying.

[0003] The method of laying optical cables overhead usually uses optical cable hooks to hang ordinary optical cables on the steel strands of the overhead lines. The steel strands bear the weight of the optical cables. The quality of the optical cable hooks has an important impact on the construction operation of the overhead laying and the protection of the optical cables.

[0004] However, in the prior art, most of the optical cables are hung on the outer wall surface of the steel strands by hooks, but some of the hooks are not hung well on the outer wall of the steel strands, which may cause partial relaxation after a period of hanging, which may cause the optical cables to shift, stretch and be partially damaged, affecting their use. At the same time, after a long period of hanging by the hooks, some parts of the optical cables may be over-pressed, causing the protective layer of the outer wall to deform, affecting the normal use of the optical cables. For this reason, we propose an overhead installation hook for communication optical cables to solve the above problems. Utility Model Content
