Cat6a Install project

CAT6 is fine up to about 30metres for 10gbit. Apparently it can manage 40m+ but I've never seen it in the real world.

Termination of Cat6 and Cat6a is tricky due to the rather extreme requirements - 2mm or 4mm maximum untwisted, something like that.

I think it's 3mm, or at least that's what I was taught when installing.

It's actually not that hard to punch down to 3mm or less, it's the bend radius and trying to stop plasters from tieing the cabling in bundles (out of the way), when on site that's the hard part.
 
When installing Cat6 and Cat6a, is there any way to tell if it is connected to that standard? for instance I'm sure you can bodge the wiring and still get 1 Gb/s out of Cat6a, but due to the shoddy work not get 10 Gb/s. Is there any way to check what a cable is capable of rather than just a yes/no from a cable tester to check the cable simply works?

When commissioning, you can test the maximum bandwidth of a cable with expensive testers (Fluke et al).

You can hire these if you don't want to buy them outright :)

Brand-rex will probably certify over 30mts on CAT6, we have mostly CAT5e and in places they have certified the cabling for 100meg at 135mts. They will only do this if it is a complete solution, ie patch leads, patch panels and cabling using their products, but it does go to show the headroom there is in the standards if good quality equipment is used...
 
Does it matter how much the cable bends behind the faceplate as one of my cables on the left will have to bend to fit behind the module?

Can't testify to the 1810g specifically, but any managed or "smart" gigabit switch will be plenty for your needs.
Personally I've got a 3com 2916 and a 3com 4924, both work superbly and were picked up for a quarter the price of an 1810g.
 
I've just installed a PS4000 SAN using two 1800 series 24ports. (I know, don't get me started...) Not the correct hardware for the job but at present with a single array on them the tests came back ok, and the system running on it goes live this morning so we'll see what happens. But they seem to be pretty robust with decent throughput.
At home I have one of the 8 port netgear smart switches, which I'd also vouch for aside the face that they are prone to overheating and crashing if not kept well ventilated.

re: cabling usually with CAT6 or 6a I stick to just two modules in a 2 gang back box, unless they're the full depth 4 cables gets a bit crowded and maintaining 1" radius gets tough.
