The remote cable is usually in the form of a full medium, that is, a non-metallic reinforcement is used. Since the BBU+RRU remote base station has small requirements on the number of cores of the optical cable, it is flexible in combination, and an optical hybrid structure can also be used in individual scenarios. In order to reduce the diameter of the optical cable, the cable is generally extended. The use of tight- fitting optical fiber can further improve the tensile and anti-pressure performance of the optical fiber , and facilitate the end-to-end processing with the quick connector. The reinforcing member adopts aramid yarn, which can improve the short-term tensile force and flexibility of the optical cable, considering The cable is used in indoors, so the jacket is made of LZSH sheathing material.
