http://www.lightreading.com/document.asp?doc_id=42956&site=lightreading http://grouper.ieee.org/groups/802/3/10GBCX4/ Regarding the first URL, I am curious how many networks will be interested in using a 15 metre 10GbE solution. Even for intra-MMR xconns, it seems like the cable length limit will very quickly become an obstacle. I guess it depends what price point copper 10Gb solutions enter the market at, compared to their optical counterparts.

Until the distances become reasonable, it will probably be a connection of opportunity. Instead of nxGE you can use 1x10GE for an MMR x-connect. The question is will people be converting 10GE copper to fiber to bridge the distances and then back? There are no highly dense 10GE platforms that I can think of right now, much less cost effective ones. DJ

I usually tell vendors that they need to hit the price point GE was in 2000, which we're not even near at this time. Although, 80km capable Xenpaks and STM64/OC192 WAN PHY Xenpaks will be available Q1-2004 so there is still hope that during 2004 we'll see 10GE become quite useful and at least more price effective than SDH/SONET. Question is when we'll be able to get 10km Xenpaks below $1000 and when we'll be able to get 8 port cards for major platforms with at least 40 gig full duplex bandwidth per slot at less than $10k per card, that's when 10GbE will really start to take off. The price point for GE over Copper is really silly now with the SOHO el cheapo gig switches are closing in on $10 per port, so lets hope the uplinks will start to catch up. -- Mikael Abrahamsson email: swmike@swm.pp.se
While there are some smitherings about 10GigE, there are technical reasons and market reasons it is not really ready for prime yet, that is not to say it's not going to happen, it is just not going happen now. -Henry Mikael Abrahamsson <swmike@swm.pp.se> wrote: On Wed, 5 Nov 2003, Deepak Jain wrote:

10GigE fiber will be the better choice in the long run.... -Henry Deepak Jain <deepak@ai.net> wrote:
