Provided are techniques, devices and systems that enable updating of a reportable parameter table database when a reconfigured optical communication path is formed by switching performed by a branching unit in an undersea optical communication transmission system. A processor may obtain system attributes of each respective segment of a number of segments of the reconfigured optical communication path from a first end point to a second endpoint. The system attributes of each respective segment of the number of segments may be evaluated from the first end point to the second endpoint of the reconfigured optical communication path. A reportable parameter table may be generated based on the evaluated system attributes that includes a listing of operational and structural parameters of system from the first endpoint to the second endpoint of the reconfigured optical communication path.

Enhanced line monitoring and parameter reporting for high fiber count undersea fiber optic transmission systems with multiple switchable branches

Submarine cable branching units with fiber pair switching configured to allow any number of trunk cable fiber pairs to access the optical spectrum any number of branch cable fiber pairs. Access to a particular branch terminal is not limited to predefined subset of the trunk fiber pairs. This approach allows fewer branch cable fiber pairs to be equipped in each branching unit, reducing system cost, simplifies system planning and provides flexible routing of overall trunk cable capacity.

Submarine cable branching units with fiber pair switching

A docking/charging module for an undersea autonomous vehicle comprises a housing allowing the undersea autonomous vehicle to dock, thereby establishing both a data connection and a power connection between the module and the vehicle, the module being equipped with the battery which is charged from an undersea cable having a power conductor which may charge the undersea autonomous vehicle via the power connection when the undersea autonomous vehicle is docked with or in proximity to the docking/charging module.

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.

Pair routing between three undersea fiber optic cables

Disclosed is an undersea power routing device including a first coupling port, a high voltage converter a second coupling port. The first coupling port may be configured to be coupled to an electrical power conductor and fiber optical cables of an undersea branch cable. The high voltage converter may be coupled to the first coupling port and operable to connect to the electrical power conductor via the first coupling port. The high voltage converter may be further operable to convert a high voltage electrical power supplied by the electrical power conductor to an output voltage having a lower voltage electrical power than the high voltage electrical power. The second coupling port may be configured to couple the high voltage converter to an interconnect cable. The high voltage converter, when coupled to the interconnect cable, may be operable to distribute the lower voltage electrical power to the interconnect cable.

A novel branching unit provided. The branching unit may include a first port for connecting a first power conductor disposed in a first optical cable, a second port for connecting a second power conductor disposed in a second optical cable, and a third port for connecting a third power conductor and a fourth power conductor disposed in a branch cable. The third port may include a first sub-port and a second sub-port. The first sub-port may be configured to connect the third power conductor of the branch cable. The second sub-port may be configured to connect the fourth power conductor of the branch cable.

A system and method consistent with the present disclosure provides for automated line monitoring system (LMS) baselining that enables capturing and updating of operational parameters specific to each repeater and associated undersea elements based on high loss loopback (HLLB) data. The captured operational parameters may then be utilized to satisfy queries targeting specific undersea elements in a Command-Response (CR) fashion. Therefore, command-response functionality may be achieved without the added cost, complexity and lifespan issues related to deploying undersea elements with on-board CR circuitry. As generally referred to herein, operational parameters include any parameter that may be derived directly or indirectly from HLLB data. Some example non-limiting examples of operational parameters include span gain loss, input power, output power, gain, and gain tilt.

Techniques for parameter reporting of elements in an optical transmission system using high loss loopback (HLLB) data and a line monitoring system implementing the same

A system and method that enforces one or more policy rules on user-allocated bandwidth portions of the overall system bandwidth, for example in an optical fiber transmission system. The policy rules may limit, for example, the range of optical wavelengths, the acceptable range on the output-power-spectral density and/or the total per-band optical power within the user-allocated bandwidth that a user may provide on the system. The system may include one or more user control units that receives respective user output signals and applies all policy rules. The resulting optical output(s) of the UCU(s) may be provided an optical transmission path for transmission to a receiving terminal. In the receiving terminal, one or more UCU(s) may apply receiver policy rules, for instance by limiting the range of wavelengths transmitted to a receive subsystem. In addition, the system may be configured to dynamically add and/or remove loading signals to the transmitted signal in response to changes in loading of the user-allocated portions of the system bandwidth, e.g. through dropping or adding of channels by a user or by equipment failures.
