sion-critical applications remain up and running. For instance, you can
connect a converter to power sourcing equipment (PSE) for PoE while
also using AC adapter power, DC terminal block power, and USB bus
power. Then, if any one of these power sources fails, the other sources
will continue to supply power to the converter seamlessly.
Technically speaking
In all, there are four different ways to power the converter: with its

time to provide maximum redundancy and ensure that your mis-

media converter’s job is to bridge the gap between these

networks. Another popular application is to use a pair of media
converters to extend the reach of a copper-based network with
fiber optic cable. This is an easy way to extend your network
without adding to your repeater count.

media converters, which translate signals from multimode to
single-mode fiber optic signals. This way, you can seamlessly
