Device for bidirectional transmission of electric digital data between submarine observation drone and commanding and controlling station, has mechanism mounted with axis of drum, where speed of mechanism depends on speed of mobile

摘要

The device has an optical fiber (FO) connecting an energetically autonomous mobile and a commanding and controlling station. The optical fiber is rolled in jointive turns around a fixed drum (T) centered around an axis (delta). The drum comprises a bidirectional optic/electric conversion circuit (CC2) associated to a free end of the optical fiber. A turning unwinding mechanism (DEV2) is coaxially mounted with the axis of the drum, where rotation speed of the mechanism depends on displacement speed of the mobile.
