Remote provisioning of a reconfigurable WDM multichannel add/drop multiplexer

Remote provisioning of a nonblocking reconfigurable multichannel wavelength -division-multiplexed add-drop multiplexer (ADM) is experimentally demonstr ated. The ADM add/drop multiplexer supports many features required by the I TU optical channel layer including lightpath routing, signal conditioning a nd network/channel monitoring. Specifically, the node supports multichannel optical bypass and add/drop functions as well as optoelectronic 2R regener ation and channel drop-and-continue with wavelength translation. Provisioni ng of a slave node from a remote master node is achieved via a subcarrier e ncoded control channel. The control channel can set the full state of the A DM and demonstration of switching between two states is reported. A reconfi guration time of the order of 10 ps and BER below 10(-9) are shown in both configurations, This performance meets the requirements of next-generation reconfigurable/restorable optical networks.
