The need for 8p8c to 8p8c connectivity is of the utmost importance.
Second to is the “field breakouts”. The colour plays a huge part.
I’ve been noticing more and more breakout tails entering the market, so it needs addressing. We cannot use the 25 pair or TIA colour codes to determine the channels.
For the field, I would expect a simple visual inspection to influence deployment decisions. Looking at the solid colours to determine the channel order. Below is an image that has been the result of many conversations. An observation I’d like to present: If you look at RJ45 connectors the solid colours are visible. The order of the solid colour should dictate the channel order. Pair three in both cases is split around pair 2. Pins of multiples of 2 are considered “Hot”. QTP-B is based on the TIA-B wiring scheme.
This is where a lot of QTP development started. How to terminate this twisted 3M ribbon cable to an RJ45 Jack. Since it would not fit and CAT cable is everywhere…
QTP-A and QTP-B
Avoid testing with non T-568A cables.
It can save you a few hours of trouble shooting and frustration!
We’re Excited to announce we’ll be at NAB2105 at the Ward-Beck Systems Booth C2541!!
A user pointed out to me that the pairs Go from 1-4 in the order of SUN, SKY, GRASS and EARTH
It was too good of an observation to not share!
