Re: LU unveils OC-768 / 40Gbps Modulators.
What are the tradeoffs between DWDM and electronic digital rate increases? An old consideration sees a new argument. How will 40Gb drivers affect DWDM channel spacings? Economies?

LUCENT TECHNOLOGIES: Lucent announces
40-gigabit modular-highest speed-device
commercially available
September 29, 1999
NICE, FRANCE, M2 PRESSWIRE via
NewsEdge Corporation : Lucent
Technologies (NYSE: LU)
Microelectronics Group, the world
leader in communications
semiconductors, today announced that
it is producing in volume an
ultra-high-speed optical modulator that
systems designers can use as the basis
of next-generation fiber-optic
communications systems. The new
device, a lithium niobate electro-optic
modulator, operates at 40 gigabits
(billions of bits) per second (gbps)
which is the highest speed
commercially available in optoelectronic
devices. This is four times faster than
current-generation modulator products.
Modulators are key components for
high-speed optical transport systems.
They modulate laser output into
high-speed light pulses that transmit
voice, data and/or video signals over
fiber-optic cables.
"Lucent's new, 40-gbps lithium niobate
modulator offers systems designers a
giant step forward in meeting the
ever-increasing need to deliver more
speed and capacity in leading-edge
digital networks," said Kim Trapp,
marketing manager for Lucent's
Microelectronics Group. "We're able to
bring our customers reliable 40-gbps
performance, based on Bell Labs'
leadership in lithium niobate
technology."
The new 40-gpbs modulator is suitable
for dense wavelength-division
multiplexed systems used in high-speed
digital networks operating up to SONET
OC-768 and SDH STM-256 rates. The
device supports the wavelength range
of 1525-1565 nanometers and requires
a 6 volt power supply. The new
modulator provides the same excellent
long-term reliability and temperature
stability over the full operating range of
zero to 70 degrees Celsius as Lucent's
10-gbps modulator. The unit is
designed with an integrated
Mach-Zehnder configuration to convert
continuous laser light output into
pulses, which eliminates the need for
demanding, high-speed performance
from the laser and reduces its cost.
The modulator is built with a patented
titanium-diffusion process using z-cut
technology on a high-volume
manufacturing platform that will assure
system designers of adequate supplies
at affordable costs.
"This new product is based on
innovative technology from Bell Labs
which has for decades been a world
leader in lithium niobate technology,"
said Tom Koch, chief technology officer
of the optelectronics business of the
Microelectronics Group. "It took less
than two years for this new modulator
to move from the laboratory to the
manufacturing site."
Lucent is shipping the 40-gbps
modulator now, and has the capacity
to ship more than 100,000 10- and
40-gbps lithium niobate modulators
during the year 2000. Lucent will be
exhibiting the new 40-gbps modulator
at the 25th European Conference on
Optical Communication (ECOC' 99) in
Nice, France, from September 26
through 30. Lucent's lithium niobate
modulators, photodetectors and lasers
have been built into the majority of
optical transmission systems for
networks around the world. Lucent's
10-gpbs lithium niobate modulator won
the 1999 Corporate Technical
Achievement award, presented by the
American Ceramic Society.
