155 Mb/s WDM label channel is detected directly by switch cells in a 4/spl times/4 optical crosspoint switch matrix without added optical components. Switching performance of 10 Gb/s packets is not affected by the detection process.
We have performed 8-channel WDM transmission over 1050 km SMF using cascaded in-line SOA and DPSK modulation format for the first time, more than 6 dB of power margin was achieved over FEC threshold.
We demonstrate an integrated 32ch dynamic wavelength channel selector consisting of an AWG and a 32 /spl times/ 1 switch using PLC technology. The crosstalk is less than -35 dB, we successfully obtained a loss variation of only /spl plusmn/ 0.1 dB.
