In late January ten Starlink satellites equipped with inter-satellite laser links (ISL) were launched, and the founder of SpaceX, Elon Musk tweeted that in addition to these satellites, all future Starlink satellites would also have ISLs. The launch represents a five-fold increase of total laser terminals launched into orbit to date. In many ways this.
The last few years have seen increased optical activity as network operators look to new technologies as an emerging alternative to RF.
The last few years have seen increasing interest in space-based optical communications, driven by the convergence of multiple trends: rising small satellite data volumes, increasing security concerns and Radio Frequency (RF) spectrum congestion, to name a few.
