Power over Ethernet (PoE) is a revolutionary technique that provides both power and data in one Ethernet cable. PoE equipment eliminates the need to run power to remote network devices, which allows for greater flexibility and is ideal for remote locations where traditional power sources are not available. PoE can save time and money and is becoming more frequently used in wired and wireless connectivity applications with network devices such as wireless access points, switches and IP cameras.
Our white paper takes a deeper look at PoE, its history and how it is used in today’s telecommunications networks. Topics covered include:
History of PoE
- How the IEEE was called upon to create the 802.3af standard to help the growth of the PoE market
- Power Sourcing Equipment (PSE)
- Powered Devices (PD)
PoE Details and Variations
- Mode A vs. Mode B
- Mode A: Combining power via Phantom Powering
- Mode B: Power over Ethernet spare pairs
