The orange-clad umbilical cable enters the vehicle termination box at the top left. The termination box is fluid-filled, and a pressure compensation system enables the contents to track the ambient ocean pressure. Inside are pressure-tolerant fuses to protect downstream connector penetrators, and wavelength multiplexers used to combine multiple pieces of equipment onto each of the fiber optic cables.
