Abstract
We have used a wavelength-dilated acoustooptic cross-connect, for inde pendent routing of 8-wavelength channels separated by 2 mn. The indivi dual acoustooptic switches making np this cross-connect provide low-cr osstalk switching only for channel spacings of at least 4 nm. Total lo ss through the dilated 2 x 2 crossconnect is 9 dB, and crosstalk range s from -25 to -35 dB. Switch architectures of this kind will be needed in multiwavelength networks where channel spacings are too close to b e accommodated by a single multiwavelength switch.
