Description of the Related Art Since a submarine repeater is laid approximately in the deep sea, a circuit unit is housed in a housing having high corrosion resistance and pressure resistance. Further, when the submarine repeater is laid on the seabed together with the submarine cable from a submarine cable laying ship, several tens of meters are required.
Since a large impact of G is applied, a structure for protecting the circuit unit and the internal cable is required. Further, it is necessary to dissipate the heat of the circuit unit to the outside of the pressure housing. For this protection and heat dissipation, a heat-dissipating support (heat-dissipating buffer) such as a heat transfer wire mesh or a metal spring is provided between the pressure housing and the circuit unit.
