Makes Possible Up to 20-Gbps Transmission Speeds for Long-Reach CWDM Communications in Metropolitan Area Networks

SUNNYVALE, Calif. — June 20, 2002 — The Electronic Device Group of Mitsubishi Electric & Electronics USA, Inc., today announced that it has expanded its cost-effective uncooled ML9XX19 distributed feedback (DFB) laser diode into a family that covers eight wavelengths in the 1470- to 1610-nm range. The expanded capability makes it possible for customers to multiplex several of the 2.5-gigabit per second (Gbps) devices together to achieve data transmission rates as high as 20 Gbps in long-reach CWDM^[1] communications. As a result, customers can cost-effectively achieve significantly higher performance for Internet and data communications in metropolitan area networks connected with ADSL^[2] and FTTH^[3].

"Mitsubishi Electric has made the ML9XX19 DFB laser diode even more flexible for customers who want a less expensive way to achieve high transmission speeds for long-reach CWDM communications in metropolitan area networks," said Daniel Chen, assistant vice president of high-frequency products for Mitsubishi Electric & Electronics USA, Inc.

The ML9XX19 DFB laser diode family offers these new capabilities with the same features as the 1550-nm single-wavelength version, including its quarter-wavelength phase-shifted grating technology, wide operating temperature range (0-70 degrees Celsius), and a compact size resulting from its uncooled design.

Packaging and Availability
The upgraded ML9XX19 DFB laser diode family is available in standard 5.6-mm and 3.8-mm TO-CAN packages.

Samples of the upgraded ML9XX19 family members covering the 1510-nm, 1530-nm, 1550-nm, and 1570-nm wavelengths will be available in July 2002. Samples of the family members covering the 1470-nm, 1490-nm, 1590-nm, and 1610-nm wavelengths will be available in September 2002. Volume production of the upgraded ML9XX19 family is scheduled for December 2002.
