: I don't agree with that. What you have to remember is that "CAT5" is a
: MINIMUM standard. The cheapest CAT5 jack will meet the standard. What
: makes a jack better or worse is how much it exceeds the standard.
What you did NOT say is that out of a thousand jacks that come off the
asembly line, many, as in a statistical curve, will exceed the specs by an
acceptable margin, while a few may come close to the minimum, and very few
may even not make minimum specs. So the quality of a jack doesn't depend
on just the make or maker of the jack, but the individual jack itself.
So the m*of this story is to _never_ buy a jack made on a Monday. ;-)
: quality jack will give the link some headroom that may be needed to
: offset a less than perfect termination, or poor quality cable, or cheap
: patch cords, etc. However, a jack that justs meets the standards, along
: with a less than perfect termination, or poor quality cable, or cheap
: patch cords will lead to a link that won't pass the minimum standards.
And there are other concerns besides electrical specs. We have a GDC
modem that is used for our whole voicemail system. One of our software
people stuck an RJ-11 plug into the RJ-45 jack, and it bent the pins on
the ends down so much that they would not make contact with the RJ-45
plug. TO compound matters, the pins got bent more when we tried to
straighten them. So the cheap metal that was used for the pins was not as
strong or springy as the phosphor bronze pins used in better quality
The m*of this story is to keep the software people away from the
