doesn‘t have to be used this way. It also works as a pure converter.
It’s even ideal for temporary setups where you need to convert copper
twisted-pair interfaces to fiber media, and vice versa.

Rear-panel DIP switches enable you to configure the converter
And though it’s designed to work as a PoE PD, the PoE converter
devices to be powered by their data cables rather than by
separate power cords. The IEEE 802.3af PoE standard calls for
48 volts of AC power over any grade of UTP wire, including
Category 3, 5, 5e, and 6. The specification covers power
sourcing equipment (PSE) and powered devices (PDs). The
PSE puts power onto the UTP cable, and the PD picks it off.
of four twisted pairs of cable: two pairs for data transmission
and two “free” pairs that can be used for other purposes.
802.3af PoE uses either the spare pairs or the data pairs to
transmit power. It adds DC power to the wires using signal
transformers and picks off power at the far end the same way.
the spare pairs would seem to be counterintuitive, data and
power transmissions don’t interfere with each other because
they’re at opposite ends of the frequency spectrum.
Specifically, electricity has a low frequency of 60 Hz or less,
and data transmissions have frequencies that can range from
10 million to 100 million Hz.
available to any powered device to be 12.95 watts with a
voltage range of 36 VDC to 57 VDC. This is more than enough
to power typical PoE devices, such as wireless access points.
