Optical switches are great, but not that big a deal. A lot of people are getting them confused with optical routers, which may be impossible to invent.

Could you (or anybody) explain the difference to me? I thought that a switch was a specialized version of a router (or maybe it was the other way around).....

TIA...

JDS Uniphase Moves Into MEMS

JDS Uniphase Corp. jdsunph today announced an agreement to buy Cronos
Integrated Microsystems Inc.http://www.memsrus.com, a startup making optical switching fabric,
for $750-million in stock.

The deal gives JDS a strong capability in fabricating MEMS (micro-electro-mechanical systems),
arrays of tiny tilting mirrors for the cores of all-optical switches. Cronos is one of the few
independent outfits to design and manufacture bespoke MEMS devices for clients - vendors
making switch subsystems or whole switches. Other outfits manufacturing MEMs devices are
typically major vendors making them for their own subsystems, according to JDS Uniphase.

Cronos says it has about 20 existing customers, but declines to name them. One is suspected to
be Xros Inc. xros.com, a startup which recently launched the first optical
cross-connect to beat the 1,000 port barrier. Nortel Networks nortelnetworks.com is
now in the process of acquiring Xros for $3.25 billion in stock (see Nortel Buys A Monster
Cross-Connect and Nortel Spells Out Its Cross-Connect Strategy ).

The price that JDS is paying for Cronos works out at $11 million per member of staff - about the
going rate for optical networking startups at present, and a bargain compared to to the $36 million
per person Nortel is paying for Xros.

JDS's move is "significant" according Nikos Theodosopoulos, managing director of equity
research at Warburg Dillon Read, an investment bank. "Optical switching is the missing link in all
optical networks," he notes.

It's worth pointing out that MEMS is only one of several technologies being considered for use in
all-optical switches. Each one has its strengths and weaknesses (see The Optical Future ). JDS
says that it expects to offer most of them to its customers in the long run. It already makes
mechanical and thermo-optical switches and says that it also plans to offer liquid crystal
switching as well as MEMS components.

Right now, Corning Inc. corning.com is reckoned to have a lead in liquid crystal
technology. Startups in this field include Chorum Technologies Inc chorum.com and
Spectraswitch, Inc. spectraswitch.com
