A solid-state laser used to carry information on a tight beam, the Laser Communication system is a Light Speed system that is hard to jam and intercept. Because of this, Laser Communication is limited in range because of the speed of transfer.
The largest and most powerful of the Laser Communication Systems, a Station-based Communication Laser has an effective range of 10 Light Seconds (2,997,924 kilometers) and a Maximum Range of nearly 20 Light Seconds (5,995,849 Kilometers). However, because it's maximum range is double the effective range, a station laser comm. can only send simple text messages.
