Field Trial of In-Service PMD Measurement Using Idle DWDM Channels in Operational Long Haul Network
Long Haul Network DWDM Channels PMD Measurement
2015/5/18
In-service PMD measurement using idle channels in an operational DWDM long-haul network is realized with two novel measurement approaches during a field trial. Accurate PMD results are obtained withou...
Experimental Demonstration of Data Traffic Grooming of a Single 10-Gbit/s TDM Tributary Channel between Two 160-Gbit/s WDM Channels
Optical communications Nonlinear optics parametric process
