7.7 SUMMARY
In summary, there are many channel-degrading effects in optical networks that
affect system performance and that might need to be monitored. However, depend-
ing upon the specific network , it might not be necessary to monitor all the above
mentioned parameters.
We have covered a variety of topics and techniques on OPM in this chapter.
Some advanced OPM techniques are summarized in Table 7.1.
To enable robust and cost-effective auto mated operation of high-speed recon-
figurable optical networks, it is desi red to intelligently monitor the state of the
network as well as the quality of propagating data signals, isolate specific
impairments and locate faults, and automatically diagnose and repair the network.
The value of monitoring increases ...
