Patch Cable Adapter
November 10th, 2010Question about Passive PoE (Power over ethernet) – WRT54G + Biquad dish & Question about AMPs?
Q: Hi,
Im planning on building a biquad dish along with a wrt54g router mounted outside and powered by Passive PoE.
Im wondering, with passive PoE, if i input 12V, will the device receive the full 12v over lets say 10 metres of RJ45 Cat5e Patch cable? Can i use RJ45 Cat5e patch cable without a problem? If not what type of ethernet network cable would you recommend?
Also, while im here, if the router requires 1AMP, if i install a 80mm fan which requires 0.09AMPs, do i need a power adapter/cable which will povide 1.09amps or will 1amp be fine?
O, about amps, what kind of amps can Passive PoE carry?
Thanks
-David
A: I don’t know where you live but in most places a WRT54 running outside will simply overheat if the outside temp goes over 80-85 degrees! They weren’t built for outdoor use at all. There are better ways to do this, really there are.
Use a real outdoor access point like a Ubiquiti bullet http://www.ubnt.com/?gclid=CNiK8M21m5wCFRghDQod5whNcA
and leave the router indoors! Simply connect the bullet to the POE injector and connect the other end of the injector to the router.
Here are the reasons why.
1. It will have at least twice the power of the wrt54 at minimum. Just check the radio specifications. (The HQ will have 12 times the output.)
2. It is built to be “outdoors”
3. It is designed to operate with POE (the WRT54 can but wasn’t designed for it.)
4. The radio is simply better for long range communications.
5. There won’t be any coax cable loss at all as none is needed.
6. They are very affordable and simply work.
As far as the current needed, if the WRT needs 1amp and the fan needs .09 (which would surprise me to be that low) then yes you need more than 1 amp at the injector! Usually a 2 amp injector would be fine but at 1 amp will overload. (You might get away with it but don’t count on it.)
The 10meter length of ethernet SHOULDN’T be an issue and yes standard ethernet is ok, cat 6 is recommended as the cable itself is slightly larger inside.
POE uses the unused pairs to supply power to the unit. So one pair of wires will be negative and another pair positive. (Network communications only uses 2 pair (four wires) in the ethernet cable so the other 2 pair are available for POE.)
