…discrete DWDM optics intended for long-range OTU2 transport. Depending on the needs of the operator, the network port can be equipped with either a fixed or tunable wavelength transmitter. To protect against trunk failures, the network port offers an integrated optical protection switch option. Primary…

…second path, or protection path, is provided in the event that a failure is detected in the primary or working path. By contrast, Optical Bi-directional Line Switched Rings, O-BLSRs, use line switching to reroute traffic. When a break occurs, the nodes adjacent to the failure switch the signal, sending…
