A subsea data switch, comprising:
- a subsea housing, including a pressure resistant first chamber maintained at an internal pressure, a data switching unit being disposed in the first chamber of the subsea housing;
- at least three termination assemblies for terminating at least three subsea cables to the subsea data switch, each of the at least three subsea cables including a data line, the data line of each of the at least three subsea cables being connected to the data switching unit;
- and
- at least one of
- at least one penetrator including a glass to metal seal for leading an electrical data line into the pressure resistant first chamber, and
- at least one penetrator including a glass to glass seal for leading an optical data line into the pressure resistant first chamber,
- wherein the data switching unit is configured to provide data switching between the data lines of the at least three subsea cables, wherein at least one subsea cable includes a hose surrounding the respective data line and a respective termination assembly assigned to the corresponding subsea cable is configured to receive and terminate the hose and to pass the respective data line without the surrounding hose to the data switching unit.
