Abstract
A system having a free space optical transmission capability for data and/or control interconnection is described. Switch cards, having corresponding pairs of laser transmitters and photodetectors are placed in a chassis, at each end, facing each other. Each laser transmitter/photodetector (LTPD) pair of one switch card is targeted to a corresponding photodetector/laser transmitter (PDLT) pair of the other. System line cards have a LTPD pair on one side and a PDLT pair on the other side. A line card is positioned in the chassis so that the LTPD pair is aligned with a corresponding PDLT pair on one switch card and the PDLT pair is aligned with a corresponding LTPD pair on the other switch card. The line card may, therefore, communicate with either switch card. The line cards contain apertures so that communication between other line cards and the switch cards is not obstructed.
