I am sure this is still significant niche. > The only reason someone isn't going to use a GBIC on a new GE purchase is because the vendor is requiring that we use SFPs or another pluggable standard to get what we are trying to accomplish. Cisco's 3750 is a good example of a formerly GBIC purchase that is now a 4xSFP purchase. I can't think of any reason why you'd install equipment (new or used) today that uplinks at less than n x GE unless you have a large legacy investment or user base. If you question was a GBIC vs 1000BaseT question, that is a slightly different animal. Where ~100% of our networking purchases probably contained a GBIC somewhere last year, probably 5-10% of those this year are mostly 1000BaseT where copper is usable instead of fiber. This makes server -> network connectivity easier and less expensive. Hope this helps, Deepak Jain AiNET
