Mitsubishi Electric Offers Ultra-High-Power, DFB Laser Diode for 40-Gbps Networks.Business Editors/High-Tech Writers SUNNYVALE, Calif.--(BUSINESS WIRE)--Aug. 27, 2002 60-Milliwatt Output Sustained Over Wide Temperature Range The Electronic Device Group of Mitsubishi Electric & Electronics USA, Inc., today introduced the ML9XX37 single-mode distributed feedback (DFB DFB acronym for dark, firm, dry meat. Called also dark cutting beef. ) laser diode, a powerful continuous-wave light source for next-generation, 40 gigabit per second (Gbps) fiber optic networks. The ML9XX37 boasts a leading-edge power output of at least 60 milliwatts (mW) throughout a temperature range of 0 to 50 degrees Celsius. The device also reduces network system costs by providing temperature-controlled wavelength tuning and by extending transmissions to beyond 100 km, when coupled with a 10-Gbps external modulator. "The ML9XX37 offers customers exceptional output power for next-generation 40-Gbps networks," said Daniel Chen, assistant vice president of high-frequency products for Mitsubishi Electric & Electronics USA, Inc., "but its ability to transmit over exceptionally long distances makes it a cost-effective solution for the current generation of 10-Gbps networks." The ML9XX37 covers five channels within the C band (1530-1565 nm) for external modulation in DWDM (Dense WDM) The term given to wavelength division multiplexing (WDM) when significantly more channels were being added. Since WDM is increasingly more "dense" all the time, both terms are used synonymously. See WDM. DWDM - wavelength division multiplexing (1) applications, with 0.8-nm wavelength ITU(2)-grid spacing between channels. The device's temperature-controlled wavelength tuning can reduce module backup costs by as much as 80 percent for five-channel systems, because customers can tune one backup module for any of the five channels, thereby eliminating the need for customers to keep five non-tunable backup modules -- one for each channel. The laser diode's 100-km reach, when coupled with a 10-Gbps external modulator, can save significant system costs for extremely long-reach fiber-optic applications because fewer laser diodes are necessary to place in tandem for the entire length of the network. The ML9XX37 DFB laser diode's extremely narrow line width of less than 1 MHz contributes to its long-distance transmission capability as well as making it an excellent choice for DWDM applications. The device's 40-decibel (typical) side mode suppression ratio (SMSR SMSR Side-Mode Suppression Ratio (lasers) SMSR Sociedad Mexicana de Seguridad Radiológica (Mexican Radiation Safety Society) SMSR Single-Mode Suppression Ratio (fiber optics) ) minimizes pulse signal degradation. Packaging, Availability, and Pricing The ML9XX37 continuous-wave DFB laser diode is supplied with a carrier for easy handling and to enable chip-on-carrier production. Samples are available in September 2002, with volume production scheduled for January 2003. Pricing is $305 each in sample quantities.
