Cypress Trades 10-Gig for Access

Cypress Semiconductor Corp. (NYSE: CY) has shifted its research and development to focus on access networks, delaying some of the plans for its next generation of framers.

"We've shifted our R&D away from 10-Gig to develop a next-generation product for the access space," says Gahan Richardson, senior product marketing manager.

Of course, nearly every chip vendor and OEM is knitting an access strategy out of yesterday's frayed metro plan. But Cypress seems a bit more pessimistic than most, predicting that its 10-Gbit/s business won't hit good volumes until 2006 or 2007.

Better known as a provider of static random-access memory (SRAM) chips, Cypress has put heavy emphasis on communications chips in recent years. It's paid particular attention to features, such as virtual concatenation, that allow Sonet networks to carry Ethernet traffic more efficiently (see Making Sonet Ethernet-Friendly and Cypress Samples GFP Framer Chip).

Cypress's 10-Gbit/s efforts aren't dead, but they are slowing down. For example, the company's OC192 framers probably won't get virtual concatenation added until the second half of 2004, Richardson says (see Cypress Intros OC-192 Framer).

"It's not way out, but it won't allow me to get any design wins now," he notes.

Cypress's gloomy view of the 10-Gbit/s market doesn't seem to be shared by respondents to Light Reading's current Research Poll on 10-Gbit/s Ethernet developments. Take the poll yourself by clicking on this link.

re: Cypress Trades 10-Gig for Access When the damn breaks on 10GbE it'll come hot-n-heavy. This will be where Ehternet finally starts making a real dent in the metro market.

My reasons are farily straightforward:

1) SONET Framing for the MAN. Essential.

2) The first time an Ethernet rate matches a SONET rate. This is important for various reasons, one of which being DWDM transponders.

3) 10 gig on a fiber or a wavelength will be so much bandwidth that many customers can dump their traffic into this "data sewer" without really worrying about QoS issues. This will give equipment vendors a few more years to straighten out the QoS issues for Ethernet.

10GbE Ethernet demand will be a step function, but don't ask me when the switch gets turned on. Possibly as early as late 2004 to mid 2005, but of course we'll need the prices to come down a bit beforehand.

re: Cypress Trades 10-Gig for Access Previously Cypress has traded RPR for SONET/SDH. The company keeps trading someting or the other. It is not clear what kind of access chip is Cypress planning? When it will be out? What are its features and price in quantities?

re: Cypress Trades 10-Gig for Access Thats quite a good predictation. But what about metro ethernet VS EOS, who will win. I hope it will be all ethernet.
