Abstract

The present invention relates to the field of installation of integrated optoelectronic distribution boxes for electric power communication, in particular to a construction method for digging out optical cable connection boxes and splitting optical cables without cutting off, an optical cable digging and connection box, including a box body and a box arranged on the front of the box body The door, the branch frame and the remaining wire rack arranged in the box, the hole for pulling out the optical cable arranged on the side wall of the box, and the blocking mechanism for blocking the hole; The branching optical cable of the distribution box is not cut off. The construction method includes the following steps: the first step: reserve enough length for the optical cable that needs to be branched; the second step: put the optical cable into the box; the third step: put the line that enters the box The cable is fixed near the side wall of the box; the fourth step: peel off the outer insulation protection of the cable; the fifth step: cut off the optical fiber that needs to be split and weld the optical fiber to be connected; this not only reduces the workload and difficulty of work, but also The work cycle and construction cost are shortened, and the signal attenuation caused by welding is essentially improved.

Description

technical field [0001] The invention relates to the field of installation of a photoelectric integrated distribution box for electric power communication, in particular to a construction method for digging out an optical cable to connect a distribution box and for splitting an optical cable without cutting. Background technique [0002] During the construction of the existing electric power communication photoelectric integrated distribution box, all the optical cables entering the box are cut off first and then welded, that is: after the optical cables entering the box from the upstream communication equipment are all cut off, some of them are connected to the box. The pigtails with a certain number of cores that need to be used in the box are fused; the other part of the optical cables that are not used in the box are fused with the optical cables of the downstream communication equipment. This method of cutting all the optical cables and then welding them requires a lot o...
