When a single protected client service (of any rate) on an N-node ring requires 10*2*N 10G transponders, I would *expect* Infinera to be in the lead as far as 10G transponders shipped!! (10 per module, 2 directions , N nodes, OEO on all 10 10G signals at every node, in both directions). The more interesting stats are on 10G *in use for client traffic* and whether Infinera can satisfy the customer applications at reasonable cost and still make a profit (let alone amortize the ~300M in venture money already sunk in InP fabs etc). Surprised this comment wasn't already made with respect to this "news". Perhaps the world does not understand the Infinera architecture and constraints?

]]> Comment on Startup to Intro Lower Cost Alternative to ROADMs by: WDMBlog » Is the Market Ready for Edge-ROADMs http://www.wdmblog.com/startup-to-intro-lower-cost-alternative-to-roadms/#comment-581 Wed, 19 Jul 2006 17:52:20 +0000 http://www.wdmblog.com/startup-to-intro-lower-cost-alternative-to-roadms/#comment-581 [...] This Telephony article debates whether carriers are ready for edge-ROADMs. The first of this product breed was recently introduced by startup Nistica. The concensus from people interviewed in the article is that, aside from niche applications, there is no need yet to deploy edge-ROAMS; the argument being that the costs are still high and the particular requirements of edge networks do not match up with the remote reconfigurability advantages of ROADMs. Filed under: ROADMs Comments: [...] […] This Telephony article debates whether carriers are ready for edge-ROADMs. The first of this product breed was recently introduced by startup Nistica.

Reasons for the retreat include low carrier prices for capacity, regulatory hurdles, and realignment of investment priorities.

They had equipment from every conceivable startup during the 1999-2001 bubble... not sure if it was bought by MFN (bankrupt, acquired by abovenet) and is still in use or if Abovenet bought it on the cheap and put it to work. There were boxes from 3 startups that were already out of business. The 5200 is an 'old' Nortel platform, my bet is they are getting some good deals on newand used equipment. Interesting, scrappy little company. I wish them well! It’s funny, I was lucky enough to get a tour of a major Data Center in SFO, and I saw the Abovenet equipment.
