Abstract:
A method for managing an optical network having a plurality of nodes interconnected by a plurality of fiber links includes installing one or more active reconfigurable optical add/drop multiplexer (ROADM) cards into a node and installing a spare ROADM card into the node. The one or more active ROADM cards are configured to pass optical traffic to and from the optical network. The installed spare ROADM card is remotely activated to pass optical traffic to and from the optical network, subsequent to configuring the one or more active ROADM cards, based on one of: an event or expiration of a time period.
