Abstract

An IM-DD optical communication system at data rate of 100 Mbps is designed for links between low earth orbiting (LEO) and geostationary (GEO) satellites. It was constructed with a fibre-coupled LD transmitter and a Si-APD photodetector. The system used the NRZ format. The transmitter achieves 1W average output power with a combination of multiplex laser drivers. Due to the transmitter drastically increased output power, it allows improvement of the link budget with, at the same time, reduced telescope diameter and PAT requirements. The receiver consisted of a threshold crossing detector and a timing recovery subsystem. It achieved a bit error rate of 10^-7 at -47dBm received average signal power.
