Tether manage system for optical fiber remote control submersible

A tether manage system (TMS) for an optical fibre remote control submersible, comprising:

• an upper cylinder equipped with a counterweight, and
• a lower cylinder equipped with a buoy,
• wherein the upper cylinder and the lower cylinder are sleeved with each other, and matched electromagnets and iron plates are respectively installed in the upper cylinder and the lower cylinder;
• the upper cylinder is connected with a mother ship through a light armoured optical and power composite cable, and the light armoured optical and power composite cable is configured to provide electric power for the electromagnets, and the lower cylinder is connected with a submersible through a light load-bearing optical fibre cable;
• and an end of the light armoured optical and power composite cable inside the upper cylinder is optically connected with an end of the light load-bearing optical fibre cable inside the lower cylinder;
• wherein a junction box is installed in the upper cylinder, and the light armoured optical and power composite cable is divided into an optical cable and power cables through the junction box;
• wherein the power cables of the light armoured optical and power composite cable are electrically connected with the electromagnets, and the optical cable of the light armoured optical and power composite cable is optically connected with the light load-bearing optical fibre cable;
• wherein an upper optical fibre package and a lower optical fibre package are respectively installed in the upper cylinder and the lower cylinder;
• the optical cable of the light armoured optical and power composite cable is connected into the upper optical fibre package, and the light load-bearing optical fibre cable is connected into the lower optical fibre package;
• and the optical cable of the light armoured optical and power composite cable and the light load-bearing optical fibre cable respectively draw a part of optical fibres from the upper optical fibre package and the lower optical fibre package, respectively, and connect each other optically;
• and
• wherein two mutually sleeved transparent covers are respectively installed on opposite faces of the upper optical fibre package and the lower optical fibre package, and the optical cable of the light armoured optical and power composite cable and the light load-bearing optical fibre cable respectively draw the part of the optical fibres from the upper optical fibre package and the lower optical fibre package, respectively, to connect into the two mutually sleeved transparent covers.
