[AusNOG] 10GBase-T SFP modules?

[Skeeve Stevens]

Lincoln,

I know you live in vendor world, but most of us live in the real world.  I
work in a lot of networks, SP's, Enterprise... old and new.. and I almost
NEVER come across equipment with 10GBase-T ports in them.  I don't even
recall the last 10GBase-T port I saw - and this is on a LOT of kit.

This very much sounds like the property people saying 'The market is going
to increase and values increasing!' just to justify and push up their own
sales.

I know Arista has 10GBase-T, in fast the first 48 port 10GBase-T switch I
ever saw was an Arista.  Don't misunderstand me... I think 10GBase-T is
awesome and I recommend people consider it as a TOR over SFP+ anytime they
have a number of ports to justify it... but few do due to the lack of
portability of 10GBase-T - meaning you need those ports wherever kit is
moved to, very few people are seriously considering it as a choice to
deploy.

With cost, I am not talking about the SME crap... it is a hell of a lot
cheaper to deploy 10GBase-T switches - the switches are a bit more
expensive, but once you factor in SFP+ modules into a switch, the opticals
are much more expensive.

I also meant to the vendor who replied about the 10GBase-T <-->SFP+ module
possibility... and that making that, which would be consumed in VERY low
numbers (my opinion) that the business case would be hard - for anything -
made where the numbers shipping would be low.

Re switch availability... I live in a world of enterprise grade, and also
mainstream vendors.  Juniper has 1 switch (that I know), Cisco has a few
line-cards and mostly higher-end Nexus models (2k - which are Fabric
extenders, 5596T) and 6500 line-cards... the 4900 has some modules, but
there is nothing (I think) in the Catalyst 3000 and below series.. in fact,
even full 10G SFP+ is still rare at this level of switching.

Cisco and Juniper both still have no all 10Gb (SFP+) switches in the low
end (EX2200, EX3200, C29xx, C3xxx) ranges, much less 10GBase-T.
