Fitel Technologies Premiers High-output, 40mW Continuous Wave DFB Laser Diode.Business Editors/High-Tech Writers CLINTON, N.J.--(BUSINESS WIRE)--Oct. 17, 2001 Fitel Technologies, Inc., a leading supplier of 14xx and 980nm pump lasers for the optical communications Optical communications The transmission of speech, data, video, and other information by means of the visible and the infrared portion of the electromagnetic spectrum. market, and its parent company, The Furukawa Electric Co., Ltd., today announced the availability of a high output, 40mW continuous wave (CW) distributed feedback (DFB DFB acronym for dark, firm, dry meat. Called also dark cutting beef. ) laser for long distance signal transmission in dense wavelength division multiplexing See WDM. (D-WDM) systems. The 40mW module is currently the highest power CW DFB made commercially available in the market. The modules are in full production and are available immediately for delivery in the ITU-T See ITU. ITU-T - International Telecommunications Union grid. Fitel and Furukawa provide a full suite of technologies to support signal transmission, including directly modulated and continuous wave DFB lasers that are essential components in WDM (1) (Wavelength Division Multiplexing) A technology that uses multiple lasers and transmits several wavelengths of light (lambdas) simultaneously over a single optical fiber. systems. "Fitel and Furukawa have leveraged their capabilities in pump laser technology in order to develop these high-power DFB modules," explained John Rogers, CEO (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. of Fitel Technologies. "We're directly addressing the growing D-WDM Signaling market with a product that has the proven integrity of our flagship products." Typical output power for Distributed Feedback Lasers used in signal transmission currently vary between 10mW - 20mW. The growing need to maintain signal integrity while compensating for the optical loss inherent during multiplexing & demultiplexing has driven demand for higher power DFB modules. Fitel's 40mW CW DFB helps to maintain signal strength when the module is combined with a Lithium Niobate modulator Modulator Any device or circuit by means of which a desired signal is impressed upon a higher-frequency periodic wave known as a carrier. The process is called modulation. The modulator may vary the amplitude, frequency, or phase of the carrier. and wavelength division multiplexer. The resulting signal exhibits an extremely low chirping chirp n.

The module's low driving current (under 200mA, typical) and high spectral purity - or side-mode suppression ration (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 40dB provide both a cost effective and reliable method of signal transmission in high capacity systems. The modules are available in a full ITU-T wavelength lineup - from 1500nm to 1625nm - in order to support large channel counts and the growing reliance on L and S-band for signal transmission. "By further developing our DFB product line, we're able to support all aspects of WDM systems, from signaling, to amplification to routing," explained Gerry Bezems, VP of Sales and Marketing. "The fact that these products are developed using our core competencies is a testament to our customers that the quality and reliability synonymous with the Fitel name has been built in to these products from the onset." Fitel Technologies and Furukawa have a strong history and expertise in developing and manufacturing laser diode modules, and currently hold nearly 70% of the total market share for 14xx pump lasers. Furukawa has maintained its position as top manufacturer of 14xx pump lasers by leveraging the production capacity at its facility in Chiba, Japan, something it will continue with its new suite of signaling products. Fitel Technologies, Inc., is a wholly owned company that develops and markets a wide variety of fiber optic and optoelectronics solutions by The Furukawa Electric Company, Ltd., of Japan. Fitel is headquartered in Clinton, NJ. For more information on Fitel Technologies, Inc., visit the company's website at www.fiteltech.com. |
