Abstract
An optical communications system including a submarine optical communications system, a landing station associated with the submarine optical communications system, a terrestrial optical communications system, a point of presence associated with the terrestrial optical communications system, a first wavelength division multiplexed optical connection between the point of presence and the landing station, and a second wavelength division multiplexed optical connection between the point of presence and the landing station and routed diversely from the first wavelength division multiplexed optical connection.

An optical communications system, comprising:
- a submarine optical communications system;
- a landing station associated with the submarine optical communications system;
- a terrestrial optical communications system;
- a point of presence associated with the terrestrial optical communications system;
- a first wavelength division multiplexed optical connection between the point of presence and the landing station;
- and
- a second wavelength division multiplexed optical connection between the point of presence and the landing station and routed diversely from the first wavelength division multiplexed optical connection.
A method of optical signal protection in an optical communications system including a submarine optical communications system and a terrestrial optical communications system, comprising:
- providing optical communications signals between the submarine optical communications system and the terrestrial optical communications system via first and second wavelength division multiplexed optical connections;
- routing the first and second wavelength division multiplexed optical connections on diverse paths so as to provide a working path and a protect path, on the first and second wavelength division multiplexed optical connections, for optical signals passing between the submarine and terrestrial optical communications systems;
- detecting a fiber cut in the submarine optical communications system;
- and
- bridging between the submarine optical communications system and the terrestrial optical communications system in response to detecting the fiber cut.
An optical communications system, comprising:
- a submarine optical communications system;
- a first landing station associated with the submarine optical communications system;
- a second landing station associated with the submarine optical communications system;
- a submarine link between the first and second landing stations;
- a terrestrial optical communications system;
- a point of presence associated with the terrestrial optical communications system;
- a first wavelength division multiplexed optical connection between the point of presence and the first landing station;
- and
- a second wavelength division multiplexed optical connection between the point of presence and the second landing station.
