Abstract

The invention provides a remote passive gain module capable of realizing state monitoring. The remote passive gain module comprises a first monitoring optical splitter the input end of which is connected with a front transmission optical fiber, wherein the secondary light splitting end of the first monitoring light splitter is connected with the first light detector, and the main light splitting end is connected with the signal end of a first signal pumping combiner; the common end of the first signal pumping combiner is connected with one end of the erbium-doped optical fiber; the other end of the erbium-doped optical fiber is connected with the input end of the unidirectional optical isolator; the output end of the unidirectional optical isolator is connected with one end of a filter, the other end of the filter is connected with the input end of a second monitoring optical splitter, the secondary optical splitting end of the second monitoring optical splitter is connected with a second optical detector, the main optical splitting end of the second monitoring optical splitter is connected with the signal end of a second signal pumping combiner, and the common end of the second signal pumping combiner is used for being connected with a post-transmission optical fiber; the reflection end of the second signal pumping combiner is connected with the input end of the pumping light splitter, and the secondary light splitting end of the pumping light splitter is connected with the monitoring photoelectric module. And the state of the remote passive gain module can be effectively monitored.

Description

technical field [0001] The invention relates to the technical field of optical transmission, in particular to a remote passive gain module capable of state monitoring. Background technique [0002] In submarine transmission or special applications on land, due to natural conditions, it is impossible to establish an active relay and monitoring system in the transmission link; or the operation and maintenance costs after using active relay are unaffordable for operators It is necessary to increase the single-span non-relay transmission distance. [0003] The remote remote pump amplifier can extend the transmission distance of the single-span non-repeater system. The remote remote pump amplifier consists of two parts: the active pump unit and the passive gain module; the passive gain module needs to be separated from the active pump unit, and the active pump unit is placed in a transmitter room with better conditions (front to the remote amplifier) ​​or the receiving end comp...
