Working on a project to run ethernet from the main house to granny flat via a buried conduit. Would prefer to not have to learn to terminate cable just for this, and figured could use keystone wall plates at each end. However, I can't figure out where best to buy the cable --- I suspect it should be external rated (as will be in conduit outside) and would need somewhere around 60-80m in length which doesn't seem readily available online. Is there a service that cuts the required length for you and terminates it? Also is cat6 strictly better than cat5e, or is it harder to work with?

Where are you based, I'd happily terminate for you if not to far out of my way.

Any electrical wholesaler will have outdoor rated cable. If it's in conduit there is no real need for outdoor cable (all it adds is UV rating) however if cable is exposed anywhere then this is important. My preference is always for gel filled for longer runs.

 

I would highly doubt you'd find anywhere that sells a cable that length online and preterminated as there would be no point. I'm sure if you asked at a wholesalers though that they'd be able to do it for you.

 

Just also be aware if the granny flat is on a different phase then technically Ethernet between the two properties could theoretically cause issues.

Cheers, have emailed a couple of local electrical wholesalers. It is two different phases...what sort of theoretical issues would there be?

Ground potential can be different if they're on different phases. This has the potential to cause damage to connected equipment.

 

I'm not saying you shouldn't to it (lots of people do) but merely pointing out what most people would be unaware of.

Except my local Cory's (Taranaki Street in Wellington). Blank stares when I asked for it.

I have a wheel of ~305M (which I have no idea how much I have left of, but should be at least half of it left) Cat6 UTP that I could help with if interested. If you have it conduited, should be fine.

 

I don't do hooking/dropping into the walls (I've done enough of this to not want to ever do this again), but can terminate to keystones if you have them and need someone to help punch it in.

 

 

Take note of @sbiddle's warning though, I've done it myself without issues, but good to know.

I've got a box of cat5e tough cable, which is outdoor rated but not gel filled. Happy to come to an arrangement to sell you the length you need and terminate it for you - I'm in Wellington.

All greater Wellington branches have cat6 gel in stock at J A Russell. Crimp gear is dirt cheap. Cat5e of the same would be available overnight.

What determines if they are on different phases? If they have individual mains meters?

I can't help with termination but I do have gel-filled CAT6A FTP cable available if you need it.

 

I strongly suggest you don't try and terminate it into plugs. Just use a socket and a patch lead at each end.

FTP cable is no good unless you're going to go have proper bonding and earthed equipment at both ends. It has the ability to introduce issues if not correctly earthed. Yes it can offer some increased noise immunity even if not correctly shielded, but an outdoor run is unlikely to expose the cable to EMF/RF sources that would cause issues.

 

If this situation where there is potential for different phases and ground potential STP cable is definitely not what anybody should be using - nor should anybody be recommending it due to the massive potential risks.

Can I suggest you really should use fibre for this ? You can get a custom fibre patch lead made by http://fs.com pretty cheaply and basic switches with SFP cages are also real cheap. You are a lot less likely to have things go badly wrong due to earthing differences that way and the cost will be not much different.
