The health status of whole fiber link.
The wave multiplexer that optical fiber Real-time and On-line is applied in industry at present（WDM）It is primarily present following ask
Topic：
1st, wave multiplexer（WDM）Be built in photoswitch, formed an entirety, can not seal off, be generally divided into 8 mouthfuls, 16 mouthfuls, 32 mouthfuls,
64 mouthfuls of equal-specifications,.If target office point tested optical fiber quantity only than these specifications port more than a bit（Such as：9th, 17,33 core
Testing fiber）, then we are still respectively necessary for 16 mouthfuls of deployment, 32, mouth and 64 mouthfuls of photoswitch.Therefore other ports can be caused
Waste.
2nd, due to wave multiplexer（WDM）It is the module formed by certain port number, if one of port there is a problem
If needing the module that more renews, this port not only to break down needs temporary transient disconnection network, other those normal ports
Also network is disconnected.In addition, if photoswitch goes wrong when needing to change, all circuits being connected on wave multiplexer are also required for
Temporarily disconnect, business is impacted.
The content of the invention
According to the deficiencies in the prior art, the present invention provides a kind of independent plug-in optical multiplexer and on-line monitoring system,
