Remote provisioning of a reconfigurable WDM multichannel Add/Drop Multiplexer
No full textRemote provisioning of a nonblocking reconfigurable multichannel wavelength-division-multiplexed add-drop multiplexer (ADM) is experimentally demonstrated. The ADM add/drop multiplexer supports many features required by the ITU optical channel layer including lightpath routing, signal conditioning and network/channel monitoring. Specifically, the node supports multichannel optical bypass and add/drop functions as well as optoelectronic 2R regeneration and channel drop-and-continue with wavelength translation. Provisioning of a slave node from a remote master node is achieved via a subcarrier encoded control channel. The control channel can set the full state of the ADM and demonstration of switching between two states is reported. A reconfiguration time of the order of 10 μs and BER below 10/sup -9/ are shown in both configurations. This performance meets the requirements of next-generation reconfigurable/restorable optical networks
A novel transmitter architecture for combined baseband data and subcarrier multiplexed control links using differential Mach-Zehender external modulators
No full textWe propose, analyze, and demonstrate a novel transmitter architecture for links that support transmission of base-band data and subcarrier multiplexed control channels. The architecture utilizes a differential external integrated-optic modulator to electrooptically combine the base-band and subcarrier multiplexed data onto an optical carrier. An analytical model is presented that allows optimization of the SNR of the received base-band and control data channels based on modulation parameters. This optimization is based on tradeoffs that result when the base-band and subcarrier channel are combined using a nonlinear modulator transfer function. We experimentally demonstrate a link based on this architecture with 2.5-Gb/s base-band and 100-Mb/s control data multiplexed on a 5.5-GHz subcarrier. Analytical and measured experimental results are compared and are shown to be in good agreement
