Abstract
The major part of the studies for introducing photonics in space are performed in the USA, but a few years ago, Saab Ericsson Space AB started a study project under a European Space Agency (ESA) contract with Ericsson Microwave Systems AB as a subcontractor. The main objectives of the project were to investigate the requirements on photonics systems and hardware for space applications and to develop space qualifiable fiber optic hybrids for a spacecraft data network. The system analysis, as well as the specifications for the fiber optic hybrids, was performed to meet the performance and environmental requirements of the Columbus Data Management System (DMS) (the fiber optic version of 10 Mbps ISO 8802-4 Token Bus). The requirements, design, and performance of these fiber optic transmitter and receiver hybrids are presented. The most important characteristics are: optical output peak power of -8.5 dBm, receiver sensitivity of -44 dBm, acquisition time of 2 microsecond(s) and a dynamic range of 27 dB.
