1. An undersea fiber optic cable architecture, comprising:
a beach manhole (BMH) installed at a terrestrial site, the BMH is communicatively coupled, by a terrestrial fiber optic cable, to a terrestrial station including one or more telemetry transceivers, the BMH including a power feed equipment;
a first enhanced branching unit (EBU) located in territorial waters adjacent to the terrestrial site;
a second EBU located in the territorial waters adjacent to the terrestrial site;
a first landing cable extending from the BMH and connected to the first EBU, the one or more telemetry transceivers controlling the first EBU via the first landing cable;
a second landing cable extending from the BMH and connected to the second EBU, the one or more telemetry transceivers controlling the second EBU via the second landing cable;
a recovery path cable connecting the first EBU to the second EBU, the first EBU, the second EBU, the first landing cable, and the second landing cable being disposed in a first underwater location;
a first trunk cable extending from the first EBU into international waters being separate from and extending away from the first underwater location; and
a second trunk cable extending from the second EBU into the international waters;
the power feed equipment, in the BMH, routing power along one or more routes defined by at least one combination of: the first and second EBUs, the first and second landing cables, and the first and second trunk cables, based on a determination of at least one of: a failure in the recovery path cable, one or more cuts in at least one of the first and second landing cables, and one or more cuts in at least one of the first and second trunk cables.
