초록

A communications link between a submarine and a torpedo secured within a launch tube flooded with seawater. A transmit/receive light beam pair propagating through the water provides the high bandwidth data channels between the tube wall and the adjacent torpedo hull for two-way communication.

A system for providing high bandwidth communications between a ship fire control system and a guidance and control system of a torpedo loaded in a launch tube, the cavity therebetween being flooded with sea water, comprising: at least transmit channel, connected to said ship and to said torpedo, for transmitting data from said ship to said torpedo, said at least one transmit channel further comprising, a first light source means, located aboard said ship, for producing a first light beam modulated in proportion to an electrical signal from said ship fire control system, a first optical transmit fiber, attached to said first light source and to said launch tube, for receiving and transmitting said first light beam across said cavity through said sea water, a first optical receive fiber, attached to the hull of said torpedo, for receiving said first freely propagating light beam incident upon said first receive fiber and transmitting said first beam, and a first photosensitive receiver means, connected to said first receive fiber, for receiving said first beam from said first receive fiber, converting the modulated light signal to a proportional electrical signal and transmitting said electrical signal to said torpedo guidance and control system; and at least one receive channel, connected to said ship and to said torpedo, for transmitting return data from said torpedo to said ship.
