Embodiment Construction
[0014] The disclosed subject matter relates to at least one improved optical-optical switching and electrical powering architecture for subsea mesh networking used in optical communication systems. According to an example, subsea optical switching and power conversion (eg, via one or more DC / DC converters) technology provides flexible fiber pair distribution and power between two interconnected subsea systems. The disclosed subject matter enables independent power down of any trunk fiber optic cable and shunt fault protection of interconnecting cables. Additionally, the disclosed switching branching unit provides any-to-any optical switching for two fiber pairs, thereby providing increased pair connectivity options.
[0015] In an example, trunk cables and interconnection cables may include optical fibers and power conductors. As described below, switching branching units (sBUs) may be configured to connect respective trunk cables to interconnection cables, and each sBU may b...

The invention discloses an optical switching and electrical powering architecture for undersea mesh networking, wherein an undersea power routing device includes 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.
Description
technical field [0001] Examples of the present disclosure relate to the field of optical communication systems. More specifically, the present disclosure relates to improved optical switching and electrical powering architectures for subsea mesh networking in optical communication systems. Background technique [0002] Long-distance optical communication systems, such as underwater optical communication systems, may include many interconnected optical cables to facilitate the communication of data and information. The fiber optic cable may be a trunk fiber optic cable and may include bidirectional trunk fiber optic pairs enabling bidirectional communication. [0003] In a subsea optical communication system, an interconnection cable via a branching unit may be used to connect a first trunk cable to a second trunk cable. In order to function, the interconnect cables must be powered. When the network is powered only between the station feeder equipment (PFE) and the subsea ...
