The umbilical cable is an armored cable that contains a group of electrical conductors and fiber optics that carry electric power, video, and data signals between the operator and the TMS. Where used, the TMS relays the signals and power for the ROV down the tether cable. Once at the ROV, the power is distributed between the electrical components.
