Paper Abstract

JPL is developing and testing a 10 Gb/s laser communications terminal for use with earth-orbiting spacecraft. The system consists of an optical transceiver head on a two-axis gimbal with a separate electronics assembly that contains the avionics, modem and laser. The link is achieved by multiplexing on the flight terminal four 0.5-W lasers in the C-band that are modulated at up to 2.5 Gb/s; transmitted through a 5-cm aperture; and received by a 1m ground aperture. A description of the system together with experimental tests of a prototype is presented.
