1. A connection device comprising:
- one or more non-dedicated, processing units; and
an optical switch for receiving Ultra-Long Haul (ULR) optical signals and for connecting at least one of the units to one or more of the received signals based on a characteristic of each signal,wherein the at least one unit is selected from the group consisting of a gigabit Ethernet unit, a re-shape and re-amplify without retiming unit (“
2R unit”
), a re-shape and re-amplify with retiming unit (“
3R unit”
), a Simple Data Link (SDL) unit and a SONET/SDH unit.

Abstract
A technique for improving optical cross-connections comprises placing a switch 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/disconnected 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.
