Description

Technical Field

[0001] The invention relates to the technical field of communication engineering construction, and in particular to an optical cable pulling clamp for communication engineering construction. Background Art

[0002] Optical fiber, referred to as optical fiber, is a light transmission tool that achieves the transmission of light based on the principle of total reflection of light in fibers made of glass or plastic. Optical cable is a communication line in which a certain number of optical fibers are arranged in a certain way to form a cable core, which is covered with a sheath and sometimes an outer sheath to realize the transmission of optical signals. As optical cable has excellent signal data transmission performance, it is widely used in communication engineering construction. However, in the process of laying optical cables, whether it is underground laying or above-ground installation, it is often necessary to pull the optical cable out of the winding device and tow it to the construction site. In the process of pulling the optical cable, a pulling chuck is often required, and the optical cable pulling chuck plays the role of fixing the connection.
