This passage is taken from the second link in my post to Reid:Message 15037987 BETTER FIBER-OPTIC SWITCHES MEMS populated with mirrors may be destined for an even more important role. One of more than 60 MEMS startups in the U.S., Optical Micro-Machines in San Diego has figured out a better answer to the fiendishly delicate problem of switching fiber-optic signals. The 14-employee company, backed by prominent venture capital firms that include Sevin Rosen Venture Partners, predicts that the MEMS devices it is developing will help telephone companies keep up with the explosion in Internet traffic. The so-called "bulk optics" mechanical switches currently used by the telecom industry have a lot of shortcomings. Using what looks like a speedometer needle, they move a fiber strand along an arc, coming to rest where it aligns with one of several other strands. Switches that can shunt signals from four incoming strands simultaneously among four outgoing ones--called four-by-four matrix switches--cost about $20,000 each. They are easy to ruin if dropped. Working with prospective telecom customers, OMM has developed smaller, more rugged MEMS switches that will cost half as much initially, and less later on, to do the same job. Customers will test prototypes later this year. The first model to go into volume production will probably be a four-by-four matrix switch with 16 tiny pop-up mirrors that can reroute signals bounced off them at a 90-degree angle. They pop up in different patterns to shunt four incoming signals as desired. Edit: This company has grown from the 14 people noted here in May to 300 today.
