France Telecom to Test LMGR Switch

NORCROSS, Ga. -- Light Management Group Inc. (NASD-OTC/BB: LMGR), developer of new applications in optical and light technologies, today announced that it has signed a letter of intent with France Telecom (NYSE: FTE) to test Light Management Group’s acousto-optic switch. France Telecom is one of the world’s largest telecommunications companies, with a network of approximately 34.1 million telephone lines, including 3.6 million ISDN channels connected to homes and businesses.

Light Management Group’s unique technology employs sound waves to manipulate light waves, thus yielding several advantages over other all-optical technologies. LMG’s acousto-optic switch operates at a speed of less than 5 microseconds, representing a 1,000-fold advantage over today’s Micro Electrical Mechanical Systems (MEMS) technology. Light Management Group’s switch, which can transform optical signals from one input channel to over 1,000 output channels, contains no moving parts and has performed over one trillion cycles entirely free of maintenance.

The agreement with France Telecom helps demonstrate Light Management Group’s commitment to its strategy of showcasing its technologies to companies of the highest integrity; the pact will reflect the manner in which LMG’s technology can be tailored to meet the needs of its potential partners and customers throughout the world. "We look forward with great anticipation to the validation of our technologies through the scientific findings that will be derived from this testing with France Telecom," said Barrington L. Simon, Chairman and CEO of Light Management Group Inc.

re: France Telecom to Test LMGR Switch a fairly written article. Where are the subtle negative comments that we have grown so accustomed to in LightReading articles about LMG?

Too bad they didn't mention that FT is the second potential customer that is testing LMG's switch.

re: France Telecom to Test LMGR Switch Don,

LMG's 8x64 switch operates with a switching time of 90 ns (nanoseconds). Take a look at these scans of the brochures they were handing out at OFC2001:

Also, note the inclusion of the address of their new Atlanta office on the brochures. Who is paying the bills?

Thanks to visitor46 of the RB board for scanning these in.

re: France Telecom to Test LMGR Switch Don,

You don't believe me? Read the brochure!

re: France Telecom to Test LMGR Switch Greg, I believe you, it's the brochures and LMGR I question. If those figures are in nanoseconds I will have to say they are typos. And while those brochure postings are great the print is fuzzy and it is hard for me to tell if it is "ns" or "us" with the front tail on the 'u' as the indicator for 'micro', called the Greek letter mu. I'm sure the intent is for it to be 'micro', I've never heard anything close to nano!

Microsecond is a millionth of a second.

Nanosecond is a billionth of a second, or a thousandth of a microsecond.

So 90 ms = .09 ns

As to belief, I'll believe whatever turns out to be the truth. I hope we find it. You may have, but I remain in doubt.

re: France Telecom to Test LMGR Switch According to the article, the time bandwidth product for the device is 64. So if the time aperture was 90 nanoseconds...the bandwidth would have to be about 500-700 Mhz. This is quite achievable in many AO materials, and given the other specs, it is likely GaP longitudinal mode...reasonably power efficient. The problem with AO switches is the higher order output limits the overall optical efficiency, and the fact it is a bulk optical process means it is transient technology. There is also not real IP barrier....Crystal Technology made devices like this 20 years ago, and up to 64 channels to boot...
