Survivability of optical connections has grown into an issue of the greatest importance for WDM networks as well as for any other optical communication technology. The interruption of high-speed optical connection even for a few seconds means a huge waste of data information. Network operators have therefore to face their customer's requirements, which are very stringent as to outage periods.

One of the most popular protection techniques is 1+1 dedicated protection, also known as self-healing. The source node splits the signal into two identical copies transmitting them simultaneously on two separate light paths. The receiver node selects the signal with the best quality.
