RE: Anybody using GBICs?
To be more clear, I'm specifically referring to Gigabit Ethernet Converters and not SFPs for POS or SONET. So, to reprhase, where in your network topology, are you using Gigabit Ethernet, specifically GE interfaces using GBICS? Are you using GE primarily for customer connections, server connections, peering points etc. ? Thanks to all who have already replied privately. -Lance-

but I need to know how many of you are using GBICs in your networks? If you are using them, where do they fit into your topology?
Anyone who runs a provider network pretty much? heh..
We use them on all core routers and colo switch uplinks..

I think you already got your answer... Most people using GigE, are using GBIC's. I don't think I've ever seen SONET gear with replaceable interfaces...
Are you using GE primarily for customer connections, server connections, peering points etc. ?
I think anyone who's willing to pay for, or can justify GigE, is going to get a GigE connection.
I'm just curious as to what kind of question it is... apologies if I sound rude to you.. but... What difference does this question make from following: "I am doing a research about GigE connectivity. How many people use Gigabit PCI NIC's in their servers, and where in your systems division do you use them the most??" GigE is gives you.. 1 gigabit of connectivity. So.. anything that requires more than 100baseTX bandwidth, and with shorter distance, anyone would use GE whether its customer, peering, backbone, workstation, or even home computer, whatever works. Ethernet is all about Al Cheapo port cost at fast speeds ;-) -Hc -- Haesu C. TowardEX Technologies, Inc.

Lance; Having been on both sides of the fence, I know that it is hard for router development engineers, especially at legacy vendors, to know what is really going on in the market. But for ISPs operators, the audience of this group, your question comes across as a "duh" moment. Everyone I know is using GBICs on 95% of new purchases. We are a regional provider in a relatively rural rural region (Maine and New Hampshire). Even in this rural market 95% our purchases next year will be GBICs running GE. However, most of those GBICs will have some involvement with Wave Division Multiplexing to get multi-GE rates. 10GE is just not needed right now by us, but I suspect people in more populated regions are using it. POS, Sonet and ATM are dead except for small players and some legacy providers. I am sure this is still significant niche. Hope this helps. regards, fletcher

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
