The specs for crosstalk would seem to differ. When I talk about
improvements, I mean in terms of electrical signal integrity.
...
I think the jury is still out on that one. It would be nice to see fiber to
the desktop, but I don't see many companies adopting that. It would seem
that as long as copper can achieve the same throughput, many people aren't
going to switch. I agree that we should and will offer a fiber version of
our product, but nonetheless, if our aim in the copper version is to
provide the highest performance and reliability, I believe that Cat6 is the
best way to do this, or at least to avoid being potentially hampered by
connector performance.
Yes, I know. We are looking to offer a 10GB version as well.
My point is, if they've gone to the trouble to create and ratify a Cat6
standard, all the Cat6 certified cable, patch panels, etc. in the world in
your network aren't going to mean anything if the basic card sitting in
your server or workstation has a Cat5 or Cat5e jack. At that point the end-
to-end rating of the network is Cat5/5e. Is it not best to support Cat6?
Then, you know that your card won't be the limiting factor in a customer's
network. I agree that not all or indeed many customer networks will be end-
to-end Cat6, but why be the one to break those that are?
Absolutely I did know that. Technically, it's using 125Mhz signalling on
the GMII interface, using all 4 pairs of the cable interface. But that
doesn't mean that a cleaner connection wouldn't result in a potentially
more error-free transmission. It only stands to reason, the less noise and
crosstalk you have on the lines, the better your signal, the fewer errors.
You sound like you're the victim of marketing hype.
We have plans for going to VoIP, which will use phone sets between the
wall and the PC. For these to have 911 reliability, they will have to
have power supplied thru the Cat5 from the switch. Ssince this uses
one pair, there will be only three pairs left, meaning that none of
the cat5s with phones will support GbE.
We're installing new Crisco switches all over the place, but none of
them will support GbE, even tho all the Dells we're getting have a GbE
NIC. We don't see GbE to the desktop for another five years.
And the way I see it is that if we were to make GbE available to the
desktop, we would just have the same problem we had back in the days
when 10Mb was all that was available: the putzes out in the student
labs would clog up the network with some ghost or backup. So with
higher speed to the desktop, it's just creating another opportunity
for the putzes to clog up the backbone again.
