Optical fiber state detection method from local side to remote side

Abstract

The invention discloses an optical fiber state detection method from a local side to a remote side, which comprises the following steps: a monitoring light source of a local side client sends a detection light signal, and the detection light signal is output into active equipment; after a data service optical signal sent by a local client is subjected to wave separation by a wave separator, 1% of light enters a second optical detector to be detected to obtain P2, and the online state of the service is judged; the rest 99% of the optical signals are input into the wavelength division multiplexer of the active equipment, are combined with the optical signals output by the optical switch, and then are transmitted to a far-end client through a to-be-tested optical fiber line; and a detection optical signal and a data service optical signal are separated from passive equipment of a far-end client through a wavelength division demultiplexer, the detection optical signal is reflected back to the wavelength division demultiplexer in a reflector, and the data service optical signal is output to a client receiving end after passing through the reflector. According to the invention, each core is independently monitored, each path of light source is independent and can be used without configuration, and the availability of each path of fiber core and online monitoring of service can be obtained.

Description

Technical field [0001] The present invention relates to the field of communication networks, and more particularly to an optical fiber state detection method of a local end to the distal end. Background technique [0002] In the carrier's network, there is a large number of passive networks, which cannot be automatically reported to their own information, called "dumb resources". At present, most of the optical boxes have no effective supervision, the distribution of resources and the work conditions cannot be mastered in real time. [0003] The current resource supervision adopts human inspection mode to ensure the normal operation of the box, which is high in operation, and the actual effect is poor. [0004] Most of the current research progress from intelligent technical perspectives is a plan to monitor the location information, temperature and humidity, vibration displacement of optical boxes, etc., which is concentrated in preventing damage, unlock permission, etc. Environ...

AI Technical Summary

Problems solved by technology

At present, most of the dumb resources in optical communication boxes are not effectively supervised, and the allocation and work status of resources cannot be grasped in real time

[0003] The current resource supervision adopts the manual inspection mode to ensure the normal operation of the box. This mode has high operating costs and poor actual results

[0004] From the perspective of intelligent technology, most of the current research progress is to monitor the location information, temperature and humidity, vibration displacement, etc. of the optical box through the Internet of Things technologies such as intelligent electronic locks and intelligent gateways. In terms of environmental information and other aspects, there is no solution for monitoring and managing the link status in dumb resources
