A New Way For Subs To Communicate?

An artist's conception of how the optical modem could function at a deep ocean cabled observatory. Autonomous underwater vehicles (AUVs) collect sonar images (downward bands of light) and other data at a hydrothermal vent site and transmit the data through an optical modem to receivers stationed on moorings in the ocean. The moorings are connected to a cabled observatory, and the data are sent back to scientists on shore. Scientists, in turn, can send new instructions to the AUVs via the optical modem as well.

Optical System Promises To Revolutionize Undersea Communications -- Science Daily

Science Daily (Feb. 25, 2010) — In a technological advance that its developers are likening to the cell phone and wireless Internet access, Woods Hole Oceanographic Institution (WHOI) scientists and engineers have devised an undersea optical communications system that -- complemented by acoustics -- enables a virtual revolution in high-speed undersea data collection and transmission.
