Finisar Delivers World's First Narrowly Tunable Long-Reach CML(TM) Butterfly Transmitters for Metro, Regional, and Long-Haul DWDM Optical Networks
New 10 Gbps Transmitters Offer Long Reach up to 300 km and High Output Power of 4-7 dBm With a 4 to 8 Channel Tuning Range

SUNNYVALE, CA--(Marketwire - August 22, 2007) - Continuing to lead the drive for innovation
in the high-end telecom market, Finisar Corporation (NASDAQ : FNSR ) today
announced the completion of Telcordia GR-468 qualification and general
availability of its 10 Gbps DM80 and DM200 narrowly tunable CMLTM Butterfly
Transmitters for DWDM 300-pin transponders and telecom line card
applications. Leveraging the directly modulated Chirp Managed Laser (CML)
technology recently acquired by Finisar, the DM80 and DM200 are the world's
first narrowly tunable 10 Gbps transmitters to offer long reach and high
output power in a 13 pin butterfly package.
Transmission distance and optical output power are important performance
parameters of DWDM optical transmitters. For applications requiring the
longest reach, the DM200 transmits with an output power of 0 to 3 dBm and
can transmit at 10Gbps over distances of 300 km without requiring costly
optical dispersion compensation. For applications requiring high output
power, the DM80 can transmit distances up to 120 km with an output power of
4-7 dBm.
Narrow tunability is an important differentiator for OEMs developing
transponders for DWDM networks. A 40-channel DWDM link using
single-wavelength transmitters, for example, requires that OEMs keep an
inventory of 40 different lasers. In addition to increased purchasing and
inventory management complexity, large numbers of individualized lasers
require a longer lead time to replace when inventories run low, forcing
OEMs to maintain large component reserves. Fully tunable transmitters, on
the other hand, simplify inventory logistics but command the highest price
since it requires the combination of an expensive fully tunable laser
source and an external modulator. Narrowly tunable transmitters offer the
best of inventory simplification and lower cost. Both the DM80 and DM200
transmitters offer narrow tunability at either 4-channel, 100 GHz DWDM
spacing or 8-channel, 50 GHz DWDM spacing across both C-band and L-band,
thus reducing the supply chain complexity by a factor of 4x or 8x compared
to non-tunable sources.
"The production release of the narrowly tunable versions of both DM80 and
DM200 shows Finisar's commitment to building on its recent CML technology
acquisition," says Dr. Frank Fan, director of marketing at Finisar. "As
the only company to offer 10 Gbps long-reach narrow tunability in a
standard butterfly box format, Finisar is uniquely positioned to serve the
specific needs of the high-end telecom market."
Shipping now, DM80 and DM200 narrowly tunable CML butterfly transmitters
are available in production volumes in both 4- and 8-channel spacing at
base frequencies ranging from 186,700 GHz to 196,100 GHz. For more
