Paper Abstract

Rf and optical communication conceptual terminal designs; size, weight, and power requirements; and development costs are compared for three representative 1-Gbps links. Year 2000 technology is assumed for the designs of LEO-to-GEO, LEO-to-LEO, and LEO-to- Ground terminals based on 32-GHz rf, 60-GHz rf, AlGaAs optical, and InGaAsP/EDFA optical technologies. The optical technologies exhibit advantages in the areas of antenna size, terminal weight, and recurring cost at the 1-Gbps data rate.
