Abstract
A cross-connect switch architecture is described. A cross-connect switch device includes a cross-point switch array, a plurality of photo detectors and a plurality of amplifiers. The cross-point switch array includes a plurality of switches. Each switch is coupled between a respective photo detector and a respective amplifier and is configured to couple the respective photo detector to the respective amplifier when the switch is selected.
