SUNNYVALE, Calif. -- The Electronic Device Group of Mitsubishi Electric & Electronics USA, Inc., introduced a new 10 gigabit-per-second (Gbps) electro-absorption (EA) modulated distributed feedback (DFB) laser diode capable of DWDM(1) transmissions up to 50 km. The new ML9XX31 laser diode enables designers to use the maximum number of wavelengths available in the C Band, so that several devices can be multiplexed together to achieve data transmission rates potentially as high as 460 Gbps. As a result, the new device is an ideal light source for high-volume Internet and data communications in metropolitan area networks. "Metropolitan area network expansion drives the market right now," said Daniel Chen, assistant vice president of high-frequency products for Mitsubishi Electric & Electronics USA, Inc. "This new laser diode delivers the high performance levels demanded for intermediate-reach DWDM transmissions over these networks. While performance is always paramount, cost is also an issue. By integrating the EA modulator with the laser diode, we have produced a smaller, more power-efficient light source capable of up to 50 km transmissions at a lower cost than lithium-niobate alternatives."Mitsubishi Electric & Electronics USA Inc.
