The physical layer, data plane design of an all-optical network switch capable of scaling to 1024 ports at 25 Gb\/s per port is presented and experimentally evaluated. Fast tuning DSDBR lasers modulated with line-coded bipolar data allow combined wavelength switching and TDMA to provide packet switch-like functionality with over 2 Tb\/s of total switch bandwidth.
