Embodiment Construction

[0022] As mentioned in the background technology, in the existing optical fiber state detection scheme, it mainly focuses on the detection of whether the optical fiber is connected and whether it is synchronous, but does not detect information such as the power loss of the optical fiber. The power loss caused by the transmission signal is too large, so that the normal transmission of the signal and the realization of load sharing cannot be guaranteed, and it cannot meet the requirements of timely finding the hidden danger of the fiber through the fiber status detection and ensuring the normal operation of the signal transmission.

[0023] In order to overcome such defects, the embodiment of the present invention proposes a fiber state detection method, by detecting the optical power of the fiber interface and the state of the fiber interface, the power loss and synchronous transmission of the fiber are detected in time, and the accuracy of the fiber state detection operation is ...

Abstract

The embodiment of the invention discloses a method and a device for detecting an optical fiber state. By using the technical scheme of the embodiment of the invention, a base station detects each optical fiber interface respectively to determine the optical power and optical fiber interface state of the corresponding optical fiber interface, and then determine the corresponding optical fiber state according to the corresponding detection result. Through the processing, the power loss of optical fibers can be determined according to the detection results of the optical power, and the optical fiber synchronous transmission condition can be determined through the optical fiber interface state; and finally, the corresponding optical fiber state is determined by combining the corresponding detection results, thus the accuracy of the detection operation of the optical fiber state is improved, and in-time detection of the transmission state of the current signal of a system is ensured.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and equipment for detecting the state of an optical fiber. Background technique [0002] The current optical fiber transmission implementation scheme is to use two optical fibers to connect the base station and the RRU (Remote RF Unit, radio frequency remote unit), among which the optical fiber where the C&M (Control and management, control and management) channel is located is the main optical fiber, and the other The optical fiber is a secondary optical fiber. [0003] In the prior art, there are mainly the following schemes for detecting the optical fiber status of the main and auxiliary optical fibers: [0004] (1) Detection by sending test pulses. [0005] (2) Detect by waveform matching of OTDR (Optical Time Domain Reflectometer, Optical Time Domain Reflectometer). [0006] (3) Detect whether the test signal is reachable through optical transmission. [0...
