when the splitting line is disassembled, similar operations are performed, and after the metal sheets 1014 of the two cable units 10 are pushed in the direction a and the direction b, the metal sheets 1014 are separated from each other, and the sheath 100 is slightly pulled, so that the splitting line can be quickly realized.
Through the improvement of the structure, the effective utilization rate of the household butterfly cable can be greatly improved, the conventional household butterfly cable is generally provided with more core wires due to the structural characteristics of the butterfly cable, but in practice, according to the layout of the optical fiber interfaces and the design required by use, more core wires are left when a single butterfly cable is connected with a single optical fiber connector and cannot be effectively used, if the butterfly cable needs to be split, operations such as shearing and the like are needed, the butterfly cable structure and even the internal optical fibers are easy to damage, in addition, one butterfly cable can only be communicated with a network operator network, therefore, the use quantity of the butterfly cable needs to be doubled for realizing one end with multiple purposes, according to statistics, the effective utilization rate of the optical fibers in the butterfly cable is generally less than 60 percent, after the improvement of the invention, the indoor optical fiber cable layout with one end being multi-way can be carried out, and the indoor optical fiber layout with one end being multi-purpose can be further matched and connected after the split type butterfly cable is simply split, and the different butterfly cables can be further matched and connected, and the wiring regularity and the like of the butterfly cable are remarkably improved.
