12-channel fully-integrated CMOS-interface optical interconnect modules with an operating voltage of +3.3 V

Using an 1.3 /spl mu/m low-threshold-current LD arrays with and an SMF array, 250 Mbit/s/ch 12 channel fully integrated compact optical interconnect modules with CMOS interfaces were developed. 20 Gb/s ATM switch boards with the modules developed were demonstrated.
