Question

Custom CAT6A cable not reaching 1000mpbs

Apr 17, 2018 9:24AM PDT

Hello! I purchased this CAT6A cable: https://www.amazon.co.uk/gp/product/B01M0VB4YD/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1 and did some network cables by myself in various lengths ranging from 1 metre up to 75 metres. I'm not testing these cables from my gigabit poe switch to the actual devices (ptz cameras) and on the switch itself, even though the devices are powered up and I can still a very clear feed, only the 100mbps led turns on - the 1000mbps led stays off.

I then tried the same test but using some CAT5e cable I have and the 1000mpbs turns on without any issues.

For the RJ45 terminators I used https://www.amazon.co.uk/gp/product/B01K9Z4K7Y/ref=oh_aui_detailpage_o02_s01?ie=UTF8&psc=1

In terms of testing, I only have a continuity tester and all cables done seem to have no problems with this.

I'm wondering what could possibly be the wrong thing I'm doing here. I highly doubt it's a cable issue so i'm throwing the blame either on my selection of connectors or the way i'm terminating these ends. Just in case, here's photos of this: https://imgur.com/a/Tte21

Any help would be greatly appreciated as i'm slowly running out of options. Thanks!

Since you would have to rip open the CAT6A cable

To compare construction and be an electronics/RF engineer to spot why it may not work, MY QUESTION is a simple one. Why not use what works?

I need to use custom
Apr 17, 2018 9:56AM PDT

I am testing the setup on a smallish scale but eventually, this cable needs to be passed into a trunking so it is not possible to use pre-fabricated cables as the RJ45 ends will definitely be damaged or they will simply not pass through the trunking system. That is why we had to opt for custom cabling.

Also, the CAT5e cable I used was only for testing purposes.

There is so much competition for low cost CAT cables that you may have received a bad lot.

You proved CAT5e worked so what stops you with cutting off the ends and using the known working cable?
