ABSTRACT:
A cable rotary joint includes a spool support and a stator spool mounted on the support and having a spool axis. The stator spool holds one portion of a cable segment having a first cable end and a second cable end, and allows the first cable end to connect with a stationary cable interface in a downstream direction from the stator spool. A rotor spool mounted for rotational movement about the spool axis holds a remaining portion of the cable segment, and allows the second cable end to connect with a rotating cable interface in an upstream direction from the rotor spool. The cable segment may be a ribboned fiber-optic cable, to meet applications in which any fiber-optic core cable is deployed from a ship. A tension wind assembly between the stator and the rotor spools includes a pulley set for transporting the cable segment from one of the spools to the other in response to rotation of the rotor spool. The pulley set has a pair of lead pulleys each supported adjacent a circumference of an associated spool to lead the cable segment on or off the associated spool, and a reversing pulley arranged in relation to the lead pulleys to transfer the cable segment between them while exerting a tensioning force tending to keep the cable segment engaged with the pulley set.
