Abstract
A system comprises a trunk submarine cable, an offshore optical and power switching unit connected to the trunk submarine cable, and a plurality of feeder submarine cables connected to the offshore switching unit. The offshore switching unit is configured to dynamically connect data communication channels of a selected feeder submarine cable among the plurality of feeder submarine cables with data communication channels of the trunk submarine cable.
Claims20
A system, comprising:
- a trunk submarine cable;
- an offshore switching unit connected to the trunk submarine cable;
- and
- a plurality of feeder submarine cables connected to the offshore switching unit, wherein the offshore switching unit is configured to dynamically connect a data communication channel of a selected feeder submarine cable among the plurality of feeder submarine cables with a data communication channel of the trunk submarine cable;
- wherein the offshore switching unit is configured to dynamically switch to a new power scheme using at least the selected feeder submarine cable among the plurality of feeder submarine cables to power the trunk submarine cable based at least in response to a detected reduction in availability of power within the plurality of feeder submarine cables.
2 more elements
A method, comprising:
- monitoring a status of a channel associated with an offshore switching unit connected to a trunk submarine cable, wherein a plurality of feeder submarine cables are connected to the offshore switching unit;
- detecting a reduction in availability of one or more data communication channels of the plurality of feeder submarine cables;
- dynamically connecting a data communication channel of a selected feeder submarine cable among the plurality of feeder submarine cables with a data communication channel of the trunk submarine cable;
- and
- dynamically switching to a new power scheme using at least the selected feeder submarine cable among the plurality of feeder submarine cables to power the trunk submarine cable based at least in response to a detected reduction in availability of power within the plurality of feeder submarine cables.
2 more elements
A method, comprising:
- connecting a first feeder submarine cable to an offshore switching unit;
- connecting a second feeder submarine cable to the offshore switching unit;
- connecting a first trunk submarine cable to the offshore switching unit;
- monitoring a status of a data communication channel associated using the offshore switching unit, the first feeder submarine cable, and the first trunk submarine cable;
- detecting a reduction in availability of the data communication channel of the first feeder submarine cable;
- dynamically connecting a data communication channel of the second feeder submarine cable with a data communication channel of the trunk submarine cable;
- and
- dynamically switching to a new power scheme using at least the selected feeder submarine cable among the plurality of feeder submarine cables to power the trunk submarine cable based at least in response to a detected reduction in availability of power within the plurality of feeder submarine cables.
