Multichannel optical signal backup system and method for optical amplifier

Abstract

The invention provides a multichannel optical signal backup system and method for an optical amplifier. The multichannel optical signal backup system and method for an optical amplifier is simple andflexible in device combination, convenient, capable of greatly reducing the cost, improving stability and safety. A first optical amplifier and a second optical amplifier are connected to the input ports of a multichannel optical coupler. In normal operation, the first optical amplifier turns on a pump light source and an output multichannel optical signal is output through the output port of themultichannel optical coupler. The second optical amplifier does not output a multichannel optical signal is in a standby state. When the first optical amplifier is abnormal and has no output, the second optical amplifier turns on the pump light source to output the multichannel optical signal, the output multichannel optical signal is output through the output port of the multichannel optical coupler, and the first optical amplifier is turned off to ensure the normal transmission of multichannel optical signal.

Description

technical field [0001] The invention relates to the technical field of optical signal transmission, in particular to a multi-channel optical signal backup system and method for an optical amplifier. Background technique [0002] In the prior art, optical switches are traditionally used for optical signal backup. Optical switches are active backup, and the cost and price are extremely expensive for multi-channel optical signal backup, and the three devices of optical switch, optical amplifier A and optical amplifier B need to be synchronized at the same time. In the working state, as an optical switch for switching multi-channel optical signals and a multi-channel optical signal backup device, long-term working status increases the probability of damage to the device itself, and the cost is high, which will make the backup system itself safe and stable. reduced sex. Contents of the invention [0003] In view of the above problems, the present invention provides a multi-cha...
