Linear Technology Corporation introduces the LTC4265, an 802.3af/802.3at compliant Power over Ethernet (PoE) interface controller for high-power Powered Device (PD) applications needing up to 25.5W.
I plan on deploying 6 Ruckus R850 AP and need a switch to power them. In order to get full power the R850 needs either DC power or a PoH/uPoE switch. The Full power consumes 31W max. If I get a Cisco ...
Power over Ethernet (PoE) is a widely used term that refers to any technology enabling an Ethernet device to receive and send power over the same cable as data. Below I’ve highlighted key information ...
Power over Ethernet (PoE) is not rocket science, but it’s not plug-and-play magic either. This short primer walks through the basics with a few practical nudges for those curious to try it out. It’s a ...
Christopher Gobok answers a reader question about PSE and PD IC's. Can they handle higher loads than the current IEEE 802.3 at PoE Spec? Christopher Gobok is a product marketing engineer for mixed ...
