Re: Cheap switch with a couple 100G
An acceptable alternative would be a cheap muxponder to take say 2x40 + 2x10 and stuff it into a 100G.

Re: Cheap switch with a couple 100G
The MX204 can split each 100G port into 4x10G. Why not 4x25G ? This would give you 16x 25G which seems quite reasonable.

FS has reasonable pricing on their amplification systems for DWDM. The problem in the states is the dark fiber consolidation, so it's difficult to find someone that'll sell it to you.

Re: Cheap switch with a couple 100G
Used Cisco Nexus 93180YC (oh, I guess New, sorry, it was on eBay, so I assumed used) is about $6,500, though I've heard they go down to $4k from time to time. So then maybe that's the problem... not enough used 100G gear out there yet to make it affordable... leaving 40G as the biggest cost-effective option. Most people I know don't buy that kind of gear new, only used. It costs too much, otherwise. >From what I've gathered from active DWDM platform vendors, it doesn't matter >what you throw at it (up to the latest and greatest), they just eat it up >(assuming you have the right line cards).

A low end 100G switch is tomahawk 32x100 or tomawhawk 2 or T3 which are all basically 128x25Gb/s asics (or Qumran/Jericho) which’s is effectively more than one asic and is priced accordingly. So a mix of 1Gb/s copper ports backed by fast silicon is not immediately forthcoming at a low price. 32x100 switches are available at order of $200 a port which seems like pretty good deal to me but you’re amortizing the silicon across all the ports. > > I ask this because the transport companies seem to have given up on 40G. > > > - > Mike Hammett > Intelligent Computing Solutions > http://www.ics-il.com > > Midwest-IX > http://www.midwest-ix.com >

Re: Cheap switch with a couple 100G
The argument should be 50G is cheaper than 40G. Because serdes is 25G typically, you get 25, 50, 100 without gearboxes and retimers, so less pincount, less thermal, higher density, lower cost. But BOM impact to pricing isn't high anyhow, unless we're talking about massive port counts. If box DOES support 10GE and 40GE then the cost benefit is not there, so you need to be targeting quite specific use case, use-case large scale DCs are targeting.
