Abstract: In an optical network some optical nodes are fitted with optical switches. The optical switches support the optical coupling and decoupling of the optical nodes and the remainder of the optical network. Electrical power supply failures to a node result in the node being optically decoupled from the remainder of the optical network thereby allowing the remaining nodes to continue normal operation.
