AES X246 proposal for standards is out from the SC-02-05 working group.
This give the working group an opportunity to comment on a pattern describing Pair order and caveats of using QTP.
Not letting anything out of the bag because the manufacturers are mixed around.
Something magical about the Quad choice. QTP-4-Everyone
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
Someone at NAB asked a great question:
“How does QTP hook up to Studio Hub?”
The answer is “perfectly” with a few Q-mandments broken….
Such a great question demanded it’s own forum
