Abstract
An undersea fiber optic cable routing architecture including a branching unit coupled to three trunk cables capable of switching individual fibers in each fiber pair within a cable to either of the other two cables. The branching unit comprises a plurality of optical switches and a controller for receiving remote command signals and configuring the optical switches in accordance with the remote command signals.
Claims20
A computer-implemented method, comprising:
- selecting, using at least one processor, one or more fiber pairs in a plurality of fiber pairs in one or more undersea cables for routing of at least one transmission, the one or more undersea cables connecting one or more transmission sites;
- assigning, using the at least one processor, one or more optical switches to each selected fiber pair in the selected one or more fiber pairs;
- forming, using the at least one processor, one or more dedicated optical pathways using the selected one or more fiber pairs and the assigned one or more optical switches;
- and
- transmitting, using the at least one processor, the at least one transmission using the formed one or more dedicated optical pathways between the one or more transmission sites.
A system, comprising:
- a branching unit configured to be connected to one or more transmission sites, the branching unit including one or more optical switches;
- at least one controller communicatively coupled to the branching unit and including
- at least one processor;
- and
- at least one non-transitory storage media storing instructions, that when executed by the at least one processor, cause the at least one processor to perform operations including
- selecting one or more fiber pairs in a plurality of fiber pairs in one or more undersea cables for routing of at least one transmission, the one or more undersea cables connecting the one or more transmission sites;
- assigning the one or more optical switches to each selected fiber pair in the selected one or more fiber pairs;
- forming one or more dedicated optical pathways using the selected one or more fiber pairs and the assigned one or more optical switches;
- and
- transmitting the at least one transmission using the formed one or more dedicated optical pathways between the one or more transmission sites.
A computer program product comprising a non-transitory machine-readable medium storing instructions that, when executed by at least one programmable processor, cause the at least one programmable processor to perform operations comprising:
- selecting one or more fiber pairs in a plurality of fiber pairs in one or more undersea cables for routing of at least one transmission, the one or more undersea cables connecting one or more transmission sites;
- assigning one or more optical switches to each selected fiber pair in the selected one or more fiber pairs;
- forming one or more dedicated optical pathways using the selected one or more fiber pairs and the assigned one or more optical switches;
- and
- transmitting the at least one transmission using the formed one or more dedicated optical pathways between the one or more transmission sites.
