Systems and methods for high capacity power delivery to remote nodes

A power sourcing and management system for a power distributing fiber access network, the system comprising:

• a power sourcing equipment device comprising:
• at least one data port configured to couple to a telecommunications network;
• at least one power supply unit configured to couple to a local power supply;
• at least one hybrid power-data port configured to be coupled, via a hybrid power-data cable, to at least one remote distribution node comprising at least one internal port configured to control power flow between buses within the at least one remote distribution node;
• a power management system, wherein the power management system is configured (a) to manage power delivered to one or more remote powered devices by controlling the at least one remote distribution node via the at least one hybrid power-data port and (b) to manage power delivery to the one or more remote powered devices by selectively switching enablement of the at least one internal port;
• and
• wherein the at least one hybrid power-data port is configured to deliver power at a first voltage level to the at least one remote distribution node over at least one pair of electrical conductors of the hybrid power-data cable;
• wherein the at least one remote distribution node is configured to deliver power, at a second voltage level different than the first voltage level, to one or more remote powered devices.
