Optical path protecting instrument with band switching function and control method of optical path protecting instrument

Abstract

The invention relates to an optical path protecting instrument with a band switching function and a control method of the optical path protecting instrument. The optical path protecting instrument comprises an optical power monitoring module, an optical path automatic protecting module, a band automatic switching module, a band automatic switching module signal input end and a Tx optical fiber input interface, wherein the optical power monitoring module is interactively connected with the optical path protecting module, and the Tx optical fiber input interface is used for transmitting and receiving optical signals. A band automatic switching module signal output end is connected with the band automatic switching module signal input end through a Tx optical fiber output interface and an Rx optical fiber input interface. The band automatic switching module signal output end is connected with the signal input end of the optical power monitoring module through the Tx optical fiber output interface. By the optical path protecting instrument and the protecting method thereof, automatic detection and conversion can be performed on optical bands firstly, and the optical module bands of the optical bands are enabled to be unlimited.

Description

Technical field [0001] The invention relates to the field of optical fiber protection equipment, in particular to an optical path protection instrument. Background technique [0002] At present, only a few foreign companies have the ability to research and produce optical fiber protection equipment, mainly JDS, E-TEK, Dicon, etc., but none of them have the automatic detection function for the optical band, so they will be limited by the optical module band. With the rapid development of optical communication technology, especially the development of all-optical communication network technology, the demand for optical fiber protection equipment (including domestic demand) will increase rapidly. The development of optical fiber protection equipment with automatic detection and conversion of optical bands is of special significance for reducing the cost of network node construction and upgrading, improving the reliability of network operation and the ability to resist destruction. ...
