RJ-41?

[John O]

Someone threw this connector number at me, and I thought it was a typo.
RJ-41 is a real connector, possibly used for comms and other low-speed
stuff, but my web search has hit a wall. Does anyone know what RJ-41 is, and
how it compares to RJ-45?

Thanks!!!

Thanks, I saw that, but what the heck does it mean? With the RJ-45
description is so far off the mark from how it would be described today, I'm
not trusting, or understanding, the -41 description. RJ-45S? what is that?

My RJ-41 search results seem to point at low-speed telcom, older stuff, but
how does it compare? Argh... :-) For instance, can a RJ-41 be Cat-5
certified? Cat-6?

A lot of sites seem to get these all mixed up, and I just can't stand the
ambiguity. It's killing me. LOL

In my experience rj -41 is 3 pair Telco usually home wiring.

Can RJ-41 be CAT 5 certified? The only way to know is to test it. Me thinks
your wasting your time.

CAT-6 your pulling our leg right. THERE IS NO CAT-6. There will be a CAT-6A
when the standard is approved.

It is not mixed up they are purposely vague.

Try BlackBox.com and do some reading there or better acquire one of their
catalogs. Lots of good information.

I'm becoming convinced it is an antique telco term. Used for "fixed loss
loop data circuits", whatever in the heck those are. No need to explain...I
don't need to know. :-) Plus, blackbox doesn't even list RJ-41. Good enough
for me.

I'm curious about this idea, I've heard it a couple times. From Blackbox...

Category 6.
The next level in the cabling hierarchy is Category 6
(ANSI/TIA/EIA-568-B.2-1), which was ratified by the TIA/EIA in June 2002.
CAT6 provides higher performance than CAT5e and features more stringent
specifications for crosstalk and system noise.

The quality of the data transmission depends upon the performance of the
components of the channel. So to transmit according to CAT6 specs, jacks,
patch cables, patch panels, cross-connects, and cabling must all meet CAT6
standards. (The channel basically includes everything from the wallplate to
the wiring closet.) The CAT6 components are tested individually, and they
are also tested together for performance. In addition, the standard calls
for generic system performance so that CAT6 components from any vendor can
be used in the channel....[etc.]

I can buy the parts, my Tektronix tester can certify them, so what am I
missing?
