Issue with cat 6 connection

[Sb8389]

Hey guys
I installed a cat 6 ftp cable last week around 50metres. It goes from one cat6 faceplate to another. When I originally tested the connection it was fine with my network tester,we tested with a couple of cat 5e patch leads to check connectivity and was fine. Today the customer has brought a couple of cat 6 patch leads and re tested (getting no connection). I popped out tonight and tested the line with my tester and getting nothing, would you point towards it being a module issue as the tester would pick up open circuits so I know it’s not that.
From your experience what would you guess it could be.

Have to ask if you've confirmed the tester on a known good cable? Those Screwfix (Philex?) testers aren't super reliable. Either way you'll find out when you buzz the wires.

Was the cable pure copper or copper coated aluminium?

Was pure copper

I know they ain’t the best, but did check the patch cables I was using to check continuity and all ok, like you say bell them out and see where I am at with it.

Join all four pairs securely,at one end,and crack-on with your 28 continuity tests,at the other end...have a cup of tea,while you peruse the readings

Quite informative PEG, what 28 continuity tests would you carry out to ensure all is ok.

Check the patch leads to see if they are standard cables or crossover leads and check each cable separately whilst disconnected.

What tester are you using as I used to use a Fluke Link Runner for integrating cable runs and port locations.

Bit more advanced machine than the philex network tester from Screwfix pal haha I shall check the cables when I go back. Thanks for the advice

Also what make of faceplates/modules did you use as CAT6 can be a sod to punchdown/chrone in to the plates.

I had a similar problem,it worked,then weeks later failed.
I changed the data module,re connected,& ok....fingers crossed.
Don’t know about you,I kinda loose it a bit on these connections,not really knowing the in’s & out’s.

 

[Sb8389]

I’m back there Friday so will take in all the info I have from you guys and will pinpoint the issue hopefully

If using a chrome tool always punch down a couple of times CAT6 cable is thicker the telephone cable and can be a sod to get into the termination.

Hi,i would have carried the most basic of tests,using whatever AVI or resistance measuring device i had to hand,and would have an indication,before i had tea,whether or not it was O/C on one or all conductors.

Before i did the above,any multi-continuity or TDR type testing,i would do the following....make sure,i had the two ends of the same cable,EVEN if i fitted it initially...i would walk the route,giving every inch,a good,hard Paddington bear type stare,to look for clues.

I would be assuming the worst - and then discounting it.

....Maybe someone pulled a t&e,through one of your holes/conduits....maybe it was tight,and they pulled back and forth,and sawed through your cable,and now,one of the live conductors,is bridging or has severed,the CAT cable...

It is unlikely,but can happen,as i have seen it happen,so get stuck in,be thorough,be successful,maybe even be a hero....but sort it,invoice accordingly and then..........relax

I concur with the Paddington Bear 'particularly hard stare' approach mentioned by PEG.

should have used dog6 instead of cat6..... rougher, tougher, more atffectionate, and does not give you agonising hay fever. .
