PoE stands for Power over Ethernet
PoC stands for Power over Cable
PoH stands for Power over HDBaseT

Power-over-Ethernet is an electrical industry standard which allows electrical power to be transmitted simultaneously with data signals over Cat5e/6/7 cable.
PoE is standardised to adhere to specific voltage ranges between 37 and 57 volts. This ensures that any PoE device connected to a system receives a compatible power supply.

PoC (or Power-over-Cable) works to similar principles (supplying simultaneous power and data signals over Cat cable) but is non-standardised and is applied to proprietary systems.
Therefore, the voltage supply can be set to meet the needs of a specific product/system (which may be lower or higher than voltage range of PoE).
