MOSAIC: a multiwavelength optical subcarrier multiplexed controllednetwork

摘要

The experimental demonstration of MOSAIC, a reconfigurable WDMnadd/drop network with subcarrier multiplexed control, is presented. ThenMOSAIC network implements the optical layer protocol to support bit-ratentransparent multichannel lightpaths. Two types of add/drop multiplexersnare implemented and combined in a three-node experiment. Multihopnlightpaths are established giving an end-to-end bit error rate of betternthan 10-9 at 1.2 Gbps. The reconfigurable add/dropnmultiplexer is based on a novel dilated 2×2 acoustooptic filternswitch crossconnect and an analog optoelectronic crossconnect thatndrives a ten-wavelength laser array transmitter up to 2.5 Gbps pernwavelength. The fixed wavelength add/drop multiplexer utilizes a fastndigitally tunable laser transmitter. Both add/drop multiplexers supportnbit-rate transparent 2R optoelectronic regeneration as well asnwavelength translation. Subcarrier multiplexing on each wavelength isnused to support channel state monitoring and channel equalization asnwell as transmission of digital network control information. Systemsnexperiments demonstrate cascaded 2R optoelectronic regeneration withnwavelength translation and cascaded multichannel optical switching withnup to seven hops. It is shown that combining cascaded 2R optoelectronicnregeneration with cascaded multichannel optical switching can be used tonbalance jitter accumulation and amplified spontaneous emission generatednamplitude noise to yield high signal-to-noise ratio for lightpaths
