[[File: System_II_Telescope.png|frame|right|This system used a consumer-grade telescope as a focusing mechanism for the receiver.]]
System II was the [[OpComms]] group's second attempt at an optical link. This system featured motorized mounts, a commercial photodetector, and an upgrade to lasers, from the earlier LED matrix of [[System I]]. This link was successful at transmitting a signal across approximately 500m.
