We have recently build a garage on the front of our section and as part of this I intend to put all my networking equipment in a cupboard out there. I have installed a 28in recessed cabinet for the ONT and i intend to put in rack mounted stuff into a cupboard next to it connected to the cabinet. The intent was/is to make it future proof for 10GBE in the future.

 

I installed conduit under the garage slab which comes out under the house and i ran 5x cat6a f/utp cables under there, 4 which are connected to wall jacks, and the 5th is a spare. Ive connected them all using shielded cat6a female keystone jacks.

 

 

 

I borrowed a Fluke DTX-1800 cable tester and used the DTX-PLA002 cat6a modules to test the cables.

 

Could the wonderful people on this forum please have a quick look at the attached results and confirm they look ok, and maybe explain the downfalls/consequences of the *pass result on the NEXT test on the BED LH result sheet.

All those results look ok. What is it about NEXT (Near End X-Talk) that concerns you?

 

Anyhow, here are a couple of links that may help with interpreting them.

@GarryP Thanks for the response

 

 

 

on the Bed LH the NEXT is 0.8dB so its getting close to the limit of the standard, im juist wondering if this is likely to degrade over time and what would happen should it go below the limit? would it potentially end up not giving 10Gbe speeds?

Since RL and ACR values are good, one marginal frequency at that cable length is not worth worrying about.

 

Let us know how much throughput you get with the 10Gb equipment connected.
