All Optical Dual Ring Internetworking with Wavelength Selective 2x2 Cross Connect
03 February 2000
Internetworking between two WDM ring networks was successfully achieved using a monolithic 2x2 multi-wavelength filter. Performance of OC-192 wavelengths originating in one ring and terminating in the other ring, traversing up to three add/drop nodes and 75 kms of TrueWave fiber, was quantified. Under typical operating conditions, less than 0.5 dB penalties were incurred.
