Paper Abstract

A free space optical TDM switch at 1.32 micron is experimentally studied. The architecture of a TDM circuit switching system with a fixed transmitter and tunable receiver assignment is described. Since each user of the TDM switching system is assigned a time slot on the time frame, the corresponding receiver at the output looks only in the preassigned time slot for signal recovery. The electrical data signal from the input source is used to gate the optical pulses from the centralized source for the duration of the signal. It is concluded that large input/output switching systems are feasible.
