Abstract
An optical backplane for high-speed data communication between the ele ctronic boards of a telecommunication switching system has been demons trated successfully. A light-guiding glass plate is used for the trans port of the optical signals at low loss (-0.1 dB/cm). Hybrid grating c ouplers; are used for achromatic coupling (-1.5 dB). The backplane was integrated into a shelf of a commercial Siemens switching system with board-to-board distances up to 0.7 m and operated at a data rate of 1 .4 Gbit/s on each channel.
