SUGAR LAND, Texas--(BUSINESS WIRE)--Oct. 14, 2002

In order to serve the needs of the burgeoning market for wideband fiber optic repeaters for the wireless communications industry, Applied Optoelectronics Inc. (AOI) today announced a new line of 1550-nm analog lasers.

AOI has developed a series of lasers optimized for this stringent application, which requires low intermodulation distortion and low RIN noise. These high-performance lasers were designed for a range of applications with modulation speeds up to 2.7 GHz and are ideal for intermediate reach and long-reach applications.

The 1550-nm family will be available in a variety of configurations. Both singlemode (DFB) and multimode (FP) devices, as well as cooled and uncooled modules, are available. The DFB-1550-C5-2-A2 series and the FP-1550-C5-2-A2 series are, respectively, single- and multimode lasers for CDMA applications, while the DFB-1550-C5-2-A4 series and FP-1550-C5-2-A4 series are optimized for the high frequency demands of WCDMA and PCS systems. This combination augments AOI's current line of 1310-nm analog lasers for wireless applications and gives the company a wide range of lasers to meet the needs of wireless equipment manufacturers.

"The popularity of wireless communications and the move towards third generation systems has spurred the demand for high performance analog lasers as carriers adopt antenna remoting strategies to improve capacity and coverage. AOI's new line of analog lasers were designed to meet the stringent demands of wireless systems, particularly WCDMA," said Stefan Murry, AOI's marketing director.

"The surging higher frequency wireless 3G applications have placed a stringent performance requirement on our analog lasers. We have developed a series of lasers for these specific applications of up to 2.7 GHz with very low distortions," said Wen-Yen Hwang, AOI's vice president of Engineering.

All of these lasers are available directly from AOI and are fully tested to ensure complete compliance with all RF and optical specifications prior to shipment. They are designed to be pin-compatible with industry-standard modules.
