Tether reel
The tether reel comes in a few standard sizes and lengths depending on the
depth capability of your ROV. The parts shown below are common to all sizes.
The tether reel is connected to the ROV via the fibre optic tether cable. The
tether reel also passes data from the ROV to the Control Station via the fibre
patch cable, which is attached to the side of the tether reel.
