Monitoring of Meshed Optical Networks using Modified End-Terminals

Modern optical fibre networks are evolving from static point-to-point connections towards meshed networks with some degree of optical transparency and capability for reconfiguration. At the same time installation and operation shall be simplified, while the availability shall be kept high. In the network design this task can be accomplished by allocation of transmission margins and by control of performance parameters. For efficient implementation information about the various sources of degradation shall be extracted at the end-terminals.
