The invention further discloses other forms of light splitting monitoring devices. Through the light splitting monitoring device, the passive feature of a light path is not changed and the normal communication is guaranteed, and the monitoring of the multi-channel optical signals are smoothly realized at the same time, and the light splitting monitoring device has the characteristics of high monitoring precision, convenience for operation, wide application and the like.

Description

technical field [0001] The invention belongs to the technical field of optical fiber communication, and more specifically relates to a spectroscopic monitoring device based on multi-channel parallel optical signals. Background technique [0002] For the current fiber-to-the-home process, the proportion of investment in optical distribution network lines in fiber-to-the-home is increasing, accounting for about 60% of the total investment, and accounting for more than 90% of the initial construction costs. Therefore, the optical distribution network (ODN) has become one of the key links in promoting the construction of fiber-to-the-home (FTTH). Compared with the point-to-point (P2P) structure of traditional copper wires, the optical distribution network mostly adopts the point-to-multipoint (P2MP) topology structure, and there are more connection points in the network. Low, easy to break, so its connection is relatively difficult, and it causes the inconvenience of branching ...

Problems solved by technology

Compared with the point-to-point (P2P) structure of traditional copper wires, the optical distribution network mostly adopts the point-to-multipoint (P2MP) topology structure, and there are more connection points in the network. Low, easy to break, so its connection is relatively difficult, and it causes the inconvenience of branching and coupling, and there are problems in reliability; at the same time, fiber resources become "black box" resources due to their passive characteristics , making it difficult to manage effectively, so the main problems we are currently facing are: the existing network resources are difficult to take inventory, the actual usage is inconsistent with the resource management system records, and the opening of new services needs to go through a complicated process, which cannot match the needs of fast service opening, etc.

[0004] However, whether it is the above solutions of Huawei or ZTE, they are all based on a variety of auxiliary equipment, such as handheld PDAs, optical fiber ID sensors, GIS systems and RFID tags, etc., and in the actual monitoring process However, considering the complexity of the application and the conditions in remote areas, it is often impossible to achieve a convenient and ready monitoring process
