Abstract

In wavelength-division multiple access (WDMA) networks, many high-speed connections over different wavelengths allow vast aggregate throughput without the limitations posed by serial electronic processing of the data. Most WDMA networks are based on dynamic tuning of the transmitted or received wavelengths, hence an effective control of the multiple-wavelength traffic is of key importance. Recently proposed WDMA control protocols include the use of a tunable filter to poll through the transmitter wavelengths for setup requests directed to itself and the use of a common wavelength dedicated to control signaling.^2,3
