DS, I wholeheartedly agree with you. I read as much as I can about this area and do not feel anyone is very close. The best regular discussion board about optical technologies that I have found is here.(lots of smart posters within the industry) boards.fool.com I got burned once-bought a small stake in (STFZ)Nanovation at 17 in the early spring-watched in run to about 40 now back at 8. I have held onto the 200 shares-but confine any buying now to royalty and primates. Mostly QCOM and NTAP Back to work Trip

... the ability to change the path of the optical network configuration, re-allocating bandwidth. This is not the same as packet "switching"... Nice post. For the past six months I've seen, both here and on TMF, the difficulty people are having understand this idea. Since this discernment of functionality is one of the fundamental concepts necessary to have even a modest understanding of the Next Gen optical network, it seems to me to be worth the effort to continue to try and explain it in terms everyone can comprehend. Eric J. and you have taken a good stab at it yet I still feel that people are not "getting" it. We need to continue to think about this education problem because this switcher/router concept is a fundamental enabler to any real understanding of how to evaluate these equipment markets. --FL

No one has come up with the basic science required to analyze the data being transmitted as a light signal without first converting that light signal to an electrical signal. Until that basic science is developed, there will not be any pure optical switch. DISRUPTIVE TECHNOLOGY !! Now that you brought it up, you need to follow up on it. I am sure there are VC's in the Bay Area just dying to fund this project.

DownSouth Same point on optical switches/optical routers is made in series of articles in lightreading--using as the straw man LU's claims that its LambdaRouter was the first all optical router. lightreading.com

DS, <<A pipelining approach is practical approach today," says Blumenthal. "You tap off a small portion of the optical signal with a splitter, convert that into electronic form in a side chain, separate the header and discard the rest of the message, read the header, and then use that information to send a control signal to an optical switch. The optical signal goes right on through, and since the header by itself represents a low bit rate, the electronic portion of the switch can keep up with the optics." And indeed this same approach is suggested in numerous research papers published in various scientific journals going back to the early nineties.>> For the rest of the article go here... americasnetwork.com Greg
