1. A single cable optical data/power transmission high availability system, comprising:
a plurality of single cable optical data/power transmission powering devices;
a respective optical data/power transmission cable that is connected to each of the plurality of single cable optical data/power transmission powering devices;
a single cable optical data/power transmission powered device; and
a single cable optical data/power transmission high availability device that includes:
a respective single cable optical data/power port coupled to each respective optical data/power transmission cable that is connected to one of the plurality of single cable optical data/power transmission powering devices, wherein each respective single cable optical data/power port includes at least one port optical data conduit having a port optical data conduit cross-sectional area, and at least one port optical power conduit having a port optical power conduit cross-section area that is greater than the port optical data conduit cross-sectional area;
a single cable optical data/power connector that is coupled to the single cable optical data/power transmission powered device and that includes at least one connector optical data conduit having a connector optical data conduit cross-sectional area, and at least one connector optical power conduit having a connector optical power conduit cross-section area that is greater than the connector optical data conduit cross-sectional area;
a data communication system that is coupled to the at least one port optical data conduit on each of the respective single cable optical data/power ports, and to the at least one connector optical data conduit on the single cable optical data/power connector;
a power transmission system that is coupled to the at least one connector optical power conduit on each of the respective single cable optical data/power ports, and the at least one connector optical power conduit on the single cable optical data/power connector; and
a high availability subsystem that is coupled to each of the data communication system and the power transmission system and that is configured to:
configure the data communication system to transmit first optical data received via the at least one port optical data conduit on a first of the respective single cable optical data/power ports to the at least one connector optical data conduit on the single cable optical data/power connector, and configure the power transmission system to receive first optical power via the at least one port optical power conduit on the first of the respective single cable optical data/power ports and use that first optical power to transmit second optical power via the at least one connector optical power conduit on the single cable optical data/power connector; and
determine that a first of the plurality of single cable optical data/power transmission powering devices coupled to the first of the respective single cable optical data/power ports has become unavailable and, in response:
reconfigure the data communication system to transmit second optical data received via the at least one port optical data conduit on a second of the respective single cable optical data/power ports to the at least one connector optical data conduit on the single cable optical data/power connector, and reconfigure the power transmission system to receive third optical power via the at least one port optical power conduit on the second of the respective single cable optical data/power ports and use that third optical power to transmit fourth optical power via the at least one connector optical power conduit on the single cable optical data/power connector.
