Abstract: PROBLEM TO BE SOLVED: To provide a method and device for improving optical crossconnect. SOLUTION: A switch for improving the optical crossconnect is arranged in front of a processor. This makes the processor serve not for a particular link or exclusively for a signal. This device is connected or disconnected to/from an optical link by the switch, if necessary, to perform a plurality of processing functions (for example, reproduction, Raman pumping, dispersion equalization/ compensation, or performance monitoring). Since the processor is made not exclusively for the particular link in this way, the cost of the crossconnect and a network is reduced. COPYRIGHT: (C)2003,JPO

Abstract: A technique for improving optical cross-connections comprises placing a swit ch in front of a number of processing units. So configured, the units are no longer dedicated to a specific link or signal. When necessary, a unit is connected/disconnect ed to one or more optical links by the switch to carry out any number of processing functions, such as regeneration, Raman pumping, dispersion equalization/compensation or performance monitoring. Because the units are no longer dedicated to specific links the cost of the cross-connections and the network it is a part of can be reduced.
