Description:
Power over Ethernet (POE) applications enable standard Ethernet cables to carry both data and power to remote devices, greatly simplifying the networked system. POE reduces the number of cables needed to connect networked devices and enables systems to access locations where power is not readily available. Applications such as industrial control, video monitoring, and remote sensing are just a few of the many examples that can take advantage of the POE specification. Because POE shares the cable with the standard Ethernet protocol, it requires a higher DC voltage (57V) to traverse the >100m cable length and still provide power to the device.
