100 Gbps ptical coherent modem for low earth orbit optical inter-satellite links

Free space optical communication (FSOC) provides a viable and cost-effective solution for future satellite systems with advantages in bandwidth, unregulated frequencies, and reduced system mass, volume, and power consumption in comparison with radio frequency systems. Several FSOC systems successfully demonstrated links between spacecraft and Earth ground stations as well as inter-satellite links. Commercial industry, including companies such as SpaceX and Telesat, have taken an interest in utilizing the benefits of FSOC for proposed LEO constellations and using optical inter-satellite links (OISLs) to reduce the need for expensive worldwide ground tracking networks. State-of-the-art FSOC space terminal data rate performance is 5.625 Gbps using coherent BPSK detection, achieved by the Tesat and DLR laser communication terminal (LCT) in 2008. The Tesat and DLR LCT demonstrated LEO to LEO OSLs over a link distance of 5100 km.
