NEW MEDIUM - THE FIBER IN SPACE
Use Cases of Laser Communication
1. Optical Inter Satellite Links (OISL)
(1) GEO Data Relay for Protected Backbone => Ultra low latency and not jammable service
(2) LEO Constellation for Spacebased Internet => Gigabit connection between satellites
2. Optical Direct to Earth (DTE)
(1) Downlinks with High data rate for Small/Cube Sats => Small size, weight and power solution
