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

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
