Mitsubishi Electric's 2.5-Gbps Optoelectronic Product Suite Delivers Increased Data Transmission Speed, Reduced Power Consumption.Business Editors/High-Tech Writers Optical Fiber Communication Conference & Exhibit ANAHEIM, Calif.--(BUSINESS WIRE)--March 19, 2001 In an effort to meet the increasing demand for greater Internet speed and bandwidth, the Electronic Device Group of Mitsubishi Electric & Electronics America, Inc., has rolled out three new distributed feedback laser A type of diode laser that uses diffraction gratings rather than mirrors to create the resonance and oscillation in the cavity. It produces a finer range of wavelengths than a Fabry- Perot cavity. A distributed Bragg reflection laser is a similar technology that uses Bragg gratings. diode (DFB-LD) modules and a new DFB-LD discrete component that offer a 2.5-gigabit per second (Gbps) data transmission rate. The cooled FU-672PDF and FU-675PDF wavelength monitor modules feature unparalleled stability power benefits in long-haul and metropolitan area network (MAN) applications.

The uncooled ML7XX16 discrete component's technology offers a wide temperature range and a reduced error bit rate. The products are designed to meet International Telecommunications Union See ITU.

"By vastly enhancing the performance of this product suite through reducing power consumption, improving power output, and increasing integration, we have changed the competitive landscape for customers to ensure higher-quality module performance," said Daniel Chen, assistant vice president of high-frequency products for Mitsubishi Electric & Electronics USA, Inc. FU-672PDF and FU-675PDF Developed for the ITU standard C Band, the integrated FU-672PDF and FU-675PDF wavelength monitor 1550-nanometer (nm) DFB-LD modules operate in long-haul applications where high levels of stability for continuous wavelength (CW) operations are critical. The modules contain an integrated stabilizer that enables developers to lock the output wavelength to the ITU grid channel, thereby alleviating wavelength drift. This integration also allows for a smaller space requirement in dense wavelength division multiplexing See WDM. (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 ) systems because no external parts are required. These benefits make the modules a more cost-effective solution than modules that use external wavelength stabilizers. The FU-672PDF and FU-675PDF modules include a polarization maintaining optical fiber pigtail and use two photodiodes for the wavelength monitor and output monitor. They offer low-power consumption with a maximum optical output power of only 15 milliwatts (mW) for single-channel and 24 mW for dual-channel versions. Available in a butterfly package, the modules use a thermoelectric cooler that reduces temperature-induced changes in output power. Other features include a 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) ) of 40 decibels (dB), maximum power monitor current of 600 microamperes (uA), and a maximum wavelength monitor current of 200 uA (one-channel version) or 400 uA (two-channel version). The products also feature a wavelength discriminator dis·crim·i·na·tor n. 1. One that discriminates. 2. Electronics A device that converts a property of an input signal, such as frequency or phase, into an amplitude variation, depending on how the signal differs from a slope of 0.15 uA/GHz (typical), free spectrum range of 1600 GHz, polarization extinction ratio of 25 dB (typical), and an operating case temperature range of -20 to +70 degrees Celsius. In addition, the FU-672PDF module offers an internally matched input impedance of 25 ohms. Developers can use the 2.5-Gbps wavelength monitor DFB-LD modules as the CW source for applications that have 2.5-Gbps or 10-Gbps modulated optical outputs. Using the "CW source + 2.5-Gbps modulator" structure, the CW source is input into a 2.5-Gbps external modulator for a 2.5-Gbps modulated optical output. To obtain a 10-Gbps modulated optical output, the outputs of four of these structures can be multiplexed together, provided each of the four CW sources use a different wavelength. FU-645SDF The FU-645SDF is an uncooled, pulsed DFB-LD module in a mini dual in-line package See DIP. (hardware) Dual In-Line Package - (DIL, DIP) The most common type of package for small and medium scale integrated circuits, with up to about 48 pins. The pins hang vertically from the two long edges of the rectangular package, spaced at intervals of 0.1 inch. , which addresses the smaller module size and lower power-consumption requirements for high-speed, high-volume optical networks. The mini dual in-line package reduces size requirements by 75 percent, compared to the butterfly package. Additional features include a 25-mA maximum threshold current, 6-mW optical output power, a 1550-nm central wavelength, and a 45-dB side mode suppression ratio (typical). ML7XX16 Operating in a temperature range between -20 to +85 degrees Celsius, the ML7XX16 is an uncooled DFB-LD discrete component that has a resonance frequency of 11 GHz (typical) and an excellent side mode suppression ratio of 45 dB (typical). The ML7XX16 employs quarter-lambda phase-shifted grating to achieve stable single-mode operation, which results in a lower bit error rate throughout its wide temperature range. The device is available in a TO-CAN package. Availability and Pricing Samples of the FU-672PDF and FU-675PDF will be available in March 2001, with volume production scheduled for May 2001. Pricing for the two-channel version of either product is $2,526 each in sample quantities. Samples of the FU-645SDF are available now with volume production scheduled for March 2001. Pricing is $773 each in sample quantities. The ML7XX16 is currently in volume production. Pricing is $238 each in 100-unit quantities. About Mitsubishi Electric & Electronics USA, Inc.
