Power boost for power and data connectivity micro grids for information and communication technology infrastructure and related methods and devices

A power and data connectivity micro grid for Information and Communication Technologies (ICT) infrastructure, comprising:

• a power sourcing equipment device configured to deliver a first direct current (DC) power signal to a power port of the power sourcing equipment device;
• a power boost module having a power input port and a power output port, wherein the power boost module is configured to add a DC boost power signal to a second DC power signal received at the power input port of the power boost module;
• a first splice enclosure having a power input port, a power tap port, and a power output port;
• a second splice enclosure having a power input port, a power tap port, and a power output port;
• a first composite power-data cable configured to transmit the first DC power signal from the power port of the power sourcing equipment device to the power input port of the first splice enclosure;
• a second composite power-data cable configured to transmit the second DC power signal from the power output port of the first splice enclosure to the power input port of the power boost module;
• and
• a third composite power-data cable configured to transmit a third DC power signal from the power output port of the power boost module to the power input port of the second splice enclosure,
• wherein the third DC power signal from the power output port of the power boost module comprises the DC boost power signal added to the second DC power signal that was received at the power input port of the power boost module.
