Problems solved by technology

[0007] However, when these operations are repeated, since a plurality of optical fiber cords are entangled, there are problems such as the following, and the high density of the optical distribution panel cannot be realized, namely

[0008] 1. As the number of repetitions of the above operations increases, the tangled state of the optical fiber cords becomes very complicated, so that the optical fiber cords cannot be connected to any position of the wiring board;

[0009] 2. A single optical fiber cord bears the load of other optical fiber cords, thus deforming the optical fiber cord;

[0010] 3. Similarly, the force applied to the optical fiber cord is transmitted to the connection part of the optical connector plug at the front end of the optical fiber cord, thus increasing the optical loss

When it is necessary to convert and connect the optical fibers of the user optical cable and the intra-office optical cable due to construction projects or fault repair projects, in order to untangle the converted optical fiber and other optical fibers and prevent false cuts, it is necessary to spend on this operation. long time
