[IW] Cisco Launches 60 Watt Ethernet Power - Page 3

post #21 of 29
This could definitely be great for charging laptops/home docking.
Apple said they were trying to combine Intel's Thunderbolt and the power connector/ethernet into a single connection for laptops eventually.

This is funny because just yesterday I dug my old ethernet switch out of my closet and I was frustrated because I can't find the power supply for it. I was thinking that this little switch uses so little power you could probably power it with a ethernet cable...

What kind of voltage does this run at, and how many wires?

Actually this seems pretty good. You will need all kinds of hubs to connect it all together, but it would make for a clean and simple office or classroom, just a couple of cables per pc.

The other thing it could do is power lights over computer controlled lighting without linking the bulb directly to the mains, but its a bit pointless. However an Ethernet powered desk lamp could be useful if you have a pc with multiple Ethernet ports and you only use one.

Edit: Wow, Power over Ethernet only came just out and I've already found pointless uses for it. Its like the eureka moment when the usb cup holder was invented.

That's what I don't like about this. USB can use anything from 28 guage wire to 20 gauge wire depending on the cable length or the power requirements from USB powered device.

Ethernet is 22 or 24 gauge usually. If you used even 2 pairs to power the device that's 30 watts over each set of 22 gauge wire.
Even if they used 12 volts at 5 amps to supply 60 watts to a monitor or TV. To get 12 volt at 50 feet you'd have to supply 14 volts. And you burn up 10 watts in the wire to get a 60 watt panel running. If they are talking about 6 volts then they would need to supply 10 volt for 50 feet. The power droop is soooo dramatic that the device would have to have hugely range power supply to correct. Which is even more power loss. By the time this is over you are going to turn 60 watt panels into 80 watt panels.

Off-topic, but that seems to be what Apple has done with their Apple Thunderbolt Display.

It's a good thing they got IPv6 going for us now. Well, mostly.
