摘要：The present invention provides a method of deactivating working fiber pairs inan existing four-fiber optical ring network or system for a cost-effective and efficientallocation of the fiber resources available in the ring network. When a working fiber pairis underutilized in an existing ring network, the traffic scheduled for transmission thereonis re-routed around the network away from the fiber pair and lockouts are applied toprevent the fiber pair to be removed from being protected. The fiber pair and associated
connecting equipment thus become unused and unnecessary for traffic carrying purposesand can then be deactivated. The present invention further provides a method of
deactivating protection fiber resources in an existing optical interconnected ring networkor system. The invention uses 1:N protection principles to provide a single protectionpath on spans interconnecting nodes common to two or more optical rings. According tothe invention, the unused fiber pairs and equipment can be removed or alternatively bereprovisioned for use in other network configurations to provide a cost-effective andefficient allocation of the resources available in the network.
