ABSTRACT:
An interface assures high-speed transmission of optical data between submerged vessels. First and second vessels have pressure hulls and have a first plate transparent to optical data on the pressure hull of the first vessel and a second plate transparent to optical data on the pressure hull of the second vessel. A first optical transceiver in the first vessel is adjacent to the first transparent plate, and a second optical transceiver in the second vessel is adjacent to the second transparent plate. A layer of water between the first plate and the second plate is optically transparent to optical data to allow the first optical transceiver and the second optical transceiver to transmit and receive optical data through the first transparent plate, the water layer, and the second transparent plate.
