Optical transmission systems of the present invention include optical protection systems, apparatuses, and methods that provide increased reliability in the system. The optical system generally includes an optical switch having distinct, cooperating dedicated and shared protection sections. The shared protection sections in a plurality of nodes can be configured to provide a protection net, in which a plurality of traffic demands, or working channels, are commonly protected as protection group using one protection channels supported by the protection net.
L'invention concerne des systèmes de transmission optique englobant des systèmes de protection optique, y compris divers appareils et procédés, qui permettent d'améliorer la fiabilité de fonctionnement. En règle générale, il s'agit de systèmes à commutateur optique comportant des sections distinctes, des sections coopérantes spécialisées, et des sections de protection communes. Les sections de protection communes d'une pluralité de noeuds peuvent être conçues pour assurer un réseau de protection, de manière à fournir une protection commune à une pluralité de demandes de trafic ou de canaux de travail, qui forment alors un groupe de protection, en utilisant à cet effet des canaux de protection établis sur le réseau de protection.
