Anyone interested in IP Telephony or remote video cameras that draw power over an Ethernet cable has to be interested in some cheap 802.3af PoE (Power Over Ethernet) gear. Well I found just the thing ...

In order to make Ethernet switching devices and wireless access points more pervasive, carriers and equipment managers need a more efficient scheme for powering these systems. Answering the call, the ...

Today's PoE applications require more than 15W of power, the maximum power limit mandated for PSE by the IEEE 802.3af specification. Specifically, the IEEE 802.3af specification mandates that a PSE ...

Not sure this should go into Other Hardware or here. I have a Cisco AIR-PWRINJ-3 power-over-ethernet injector lying around, but don't have a compatible Cisco device to use with. Apparently it's ...

The LTC4257 -48V, power-over-Ethernet interface controller includes all the elements needed to connect a powered device to an IEEE 802.3af powered network. These include a precision 25k signature ...

I wanted to save a few bucks, by going for this 802.af-compliant TP-link gbit POE splitter. However, some of these reviews sound alarm bells on how even standard compliance isn't enough to make sure ...

The proposed IEEE 802.3af standard for supplying power over Ethernet cabling will ease deployment of IP telephones and wireless access points, and reduce the cost of powering the devices. The proposed ...

The 802.3af standard may increase interoperability with new products, but organizations with nonstandard power supply equipment may want to check for backward compatibility before buying the new ...

Implementing PoE is made interesting by the fact that not every Ethernet device wants power; if you start dumping power onto any device that’s connected, you’re going to break things. The IEEE 802.3af ...

Power over Ethernet (PoE) has become the colloquial term used to describe any technology that allows an Ethernet device to transmit and receive data, as well as receive power over the same cabling.

PoE, a technology Cisco pioneered in 2000, allows the delivery of DC power over the same copper wire as Ethernet, and enables customers to integrate a host of new powered network-attached devices to ...

Coupled with an external power-over-Ethernet (PoE) isolation transformer, the PTB48540 module from Texas Instruments delivers up to 10 W at 3.3, 5, or 12 V. This plug ...
