As a traditional digital signal transmission standard, E1 signal is widely used in telecommunication networks.

[0006] Line allocation and management are not flexible enough: Traditional E1 line allocation and management methods are relatively fixed and difficult to adapt to changes in network structure and expansion needs.

[0007] Low transmission efficiency: The bandwidth of copper wires or twisted pair cables is limited and cannot meet the needs of large-scale data transmission. Summary of the invention

[0008] In view of this, the present invention provides an E1 wiring device, which is used to at least solve part of the technical problems in the background technology.

[0009] In order to achieve the above object, the present invention adopts the following technical solution:

[0018] Preferably, in another embodiment, the optical fiber splitter / combiner comprises a multi-stage fiber optic splitter / combiner system composed of a plurality of optical fiber splitters / combiners, wherein the input end of the first-stage optical fiber splitter / combiner is connected to the output end of the first optical fiber transceiver, the intermediate-stage optical fiber splitter / combiner is used to converge the optical signals output by the adjacent low-stage optical fiber splitter / combiner and transmit them to the next-stage optical fiber splitter / combiner, and the last-stage optical fiber splitter / combiner is used to converge the optical signals output by the next-stage optical fiber splitter / combiner and transmit them to the second optical fiber transceiver.
