re: Nortel Buys: Reaping the Whirlwind? to note that Nortel listed the Xros/Optera PX as being 65% complete in its 2000 10-K and in its Q1, Q2, and Q3 2001 10-Q's.

re: Nortel Buys: Reaping the Whirlwind? "MEMS a fad?

what do u guys think?"

Not a fad IMHO, but for now the promise of all optical switching requiring the number of ports that a 3D MEMS is supposed to offer is quite a ways off.

2D MEMS are available now, and being used in small port count applications. When the rest of the GǣglueGǥ needed to build a true OOO switch becomes real, then maybe some demand for large port count devices will start to materialize. GǣGlueGǥ for building OOOGs include some sort of wavelength conversion process, along with some sort of low cost distributed amplification to overcome switching losses.

what do u guys think?

i'm a mems person myself.
though i don't think much of it,
i PARTIALLY agree to the quote.

re: Nortel Buys: Reaping the Whirlwind?
What is the difference, where are 2D best suited, and 3D?

Thx

re: Nortel Buys: Reaping the Whirlwind? MEMS has been used for a variety of applications during the past 30 years but despite a few relatively successful commercial applications (pressure sensors, accelerometers) it never found a killer ap. Its use in optical switching had that promise but, indeed, it was just a fad because when the smoke cleared those that bought into the hype couldn't really figure out how these mirrors were going to increase earnings. Now everybody has a MEMS switch because, well, . . . all the other guys had one and no one wanted to be left out. Very unfortunate for the MEMS industry.

Despite all that MEMS technology really isn't a fad nor is it dead albeit perhaps a tad humbled. MEMS continues to be a player in a wide range of industries and there are even companies out there doing MEMS for telecom components - although not so many any more for optical switching.

re: Nortel Buys: Reaping the Whirlwind?
i know there's been plenty of so called market forecasts for those mems products.
but most of them seem to end up as some fancy forecasts, just good enough to be used in deluding most everyone if necessary.
can someone suggest any trust worthy and detailed information on the optical switch market.

re: Nortel Buys: Reaping the Whirlwind? Hey Mems fans:

Check out startup Network Photonics; though I don't know much about MEMS, it seems they have a promising solution to most MEMS problems with their new optical switch. Seems to remove all the complexity of previous MEMS designs, and improve on reliability. If it works, could be killer.

re: Nortel Buys: Reaping the Whirlwind? Excuse my ignorance, but is it possible to do wavelength conversion optically, without some sort of OEO conversion? If so, can anyone describe the technology?

Thanks,

DD
