Frank - I would appreciate your reaction to this press release from Nortel concerning its tunable laser for DWDM. It sounds exciting. I guess the technology will allow more channels.
Thank you,

Nortel (Northern Telecom) Develops the World's
First Tunable Wavelength-Locked High-Power
Laser for Broadband Systems

-Laser Offers Significant Cost Advantages for Dense Wavelength Division
Multiplexing-
OTTAWA, Sept. 11 /PRNewswire/ - Nortel (Northern Telecom) (NYSE: NT/TSE:
NTL) has developed the world's first wavelength-locked, high-power laser that can be
tuned to generate light at different wavelengths. This capability gives customers
significant design flexibility and cost savings in Dense Wavelength Division Multiplexing
(DWDM) fiber-optic deployment.
The tunable laser uses Nortel's unique wavelength-locking mechanism, which enables
the laser to adhere to the incredibly tight tolerances required by DWDM, over a wide
range of operating conditions and throughout a laser's projected product life. Combined
with the locking mechanism, the tunable laser allows operators to select and then
accurately lock to any of the standard DWDM wavelengths, or channels, used in the
industry.
DWDM, which allows multiple wavelengths to be carried on the same fiber, is a major
technology for increasing network capacity to support the explosive growth of Internet,
data, and multimedia traffic. The precise control afforded by Nortel's locking laser
ensures that narrowly spaced wavelengths in DWDM systems do not drift out of their
acceptable range and interfere with adjacent wavelengths.
The laser can be tuned over the traditional 1530-to-1560 nanometer bandwidth range
and up to 1600 nanometers in the extended wavelength band. The extended waveband
range supports up to 80 DWDM channels at 100-gigahertz channel spacing.
The development marks the first phase of a major Nortel thrust to provide
industry-leading wavelength-selectable and wavelength-tunable lasers for high-capacity
DWDM and optical transmission systems. The first opportunities to view this new
technology will be at the National Fiber Optic Engineers Conference being held in
Orlando, Florida September 14-15 and at the European Conference on Optical
Communication being held in Madrid, Spain September 22-24.
