Description

technical field [0001] The present invention relates to the technical field of user electricity information collection devices, in particular to a telecommunications data collection switching device for plastic optical fiber that receives three signals once. Background technique [0002] At present, in the plastic optical fiber user electricity information collection system, the local optical fiber communication module of the concentrator performs data interaction with the plastic optical fiber collector through plastic optical fiber, but due to the limitation of the distance between the plastic optical fiber local communication structure and the plastic optical fiber between the two nodes, it cannot be applied In a variety of complex on-site environment. [0003] The plastic optical fiber local communication structure adopts a three-layer structure. The first layer is the plastic optical fiber local communication module of the concentrator; the second layer is the plastic o...

Problems solved by technology

[0004] The plastic optical fiber local communication network connects all the plastic optical fiber collectors in the station area in series. However, due to the complex on-site environment and the distance between plastic optical fiber nodes, it is very difficult to complete the closed loop of the local network in some occasions. During the design of the scheme, it is impossible to connect all point acquisition devices to the main ring communication network, which has great limitations in the field application process
