Abstract

A free space optical communication testbed using multi-channel optical code division multiplexing was demonstrated using a multiplexed optical transmitter utilizing SONET OC-12 signals, a pair of matched telescopes, and a single mode fiber coupled receiver and CDMA decoding system. An active beam alignment system was used at the receiver to maintain alignment on the receiver input fiber, with bit error rates under transmitter jitter of better than 2x10^-12 for a transmitter beam perturbation of 50 Hz and 45 (mu) rad peak to peak amplitude.
