PoE

See: Power over Ethernet (PoE)

The Power over Ethernet technology (PoE) allows the transfer of data and power to network devices via one single standard Ethernet cable.

Spectral Transmission

Different optical materials transmit the many wavelengths of light with differing efficiencies, and all wavelengths are reflected or absorbed in varying amounts.
