PoE VDSL2 modem?

My master socket is in the hallway, there is no power socket nearby. I intend to run an extension to where I will put the modem. This got me thinking, rather then extending the BT line to the modem what a PoE modem and then just ethernet to the router. This would keep the 'BT' side of things shorter, with less bends in the cable etc (extension will need to do a few 90degs and end up being approx 6m long).

Do these exist, or are there any that kind be powered if I split the power line out from a PoE cable?

edit:

Actually, there looks to be passive PoE things LinITX do that will just allow me to inject connect the VDSL modem PSU to the ethernet cable and just use that for PoE.

I have never heard of a VDSL modem that can be powered by PoE.

Do be careful with basic PoE injectors as you could quite easily shove power up an ethernet cable and cause damage to your equipment.

Extending your phone line by 6m with high quality cable won't make a noticeable difference to your sync rate. So just do that.

As above. PoE routers are definitely something, but modems I'm not so sure of

What's the the thinest wire I can get away with for extending the phone, and not risking sync?

Use solid core Cat5e or CW1308.

Punch it down to the unfiltered terminals on the master socket and connect the other end to a faceplate (Ethernet or RJ11).

Whichever you use you only need to connect one pair (blue/blue white by convention).

Thinner than a network cable would have been. CW1308 is the BT spec, a 3 pair cable is about 5mm.

I've powered my hg612 with one of those tp link injectors and extractors with no issues. In the end I used the poe kit for something else and ran cat5e to allow me to move the modem 20m

Thanks all. I'll look into CW1308, it doesn't *need* to be cat5e as far as I can tell and I'd rather the cable be thinner and easier to route.

Any brands of cable to get / avoid?

Make sure it's copper and not CCA (copper clad aluminium), otherwise it's all the same. Cat5e isn't really that thick though, so I'd be tempted to just run that.

Why though, what would running the cat5e instead of CW1308 do for me?

They'll both work fine. Use whatever you can get hold of most easily. I'd use Cat5e but that's just because I've usually got some kicking around spare.

One advantage of Cat5e is that you could easily revert to your original PoE plan if you decide to.
