HFE4080-32X-XBA High Speed Fiber Optic VCSEL FEATURES • Industry standard ST¨-LP fiber connector • Designed for drive currents between 5 and 15 mA • Optimized for low dependence of electrical properties over temperature • High speed > 1 Ghz 02 October 1997 DESCRIPTION The HFE4080-32X-XBA is a high-performance 850 nm VCSEL Vertical Cavity Surface-Emitting Laser intended for high-speed data communications. It combines many of the desirable features of an LED with the desirable features of a laser diode operating in a single longitudinal mode, but with multiple transverse modes reducing coherence and consequent modal noise in multimode fiber applications. APPLICATION The HFE4080-32X-XBA is a high radiance VCSEL packaged on a TO-46 header with a metal can. Data rates can vary from DC to above 2 GB/s depending upon component application. The VCSEL is designed to convert electrical current into optical power that can be used in fiber optic communications and other applications. As the current varies above threshold, the light intensity increases proportionally. The component produces a circularly symmetric, narrow divergence beam. The stability of operating characteristics with temperature potentially allows operation without continuous photodiode feedback control, simplifying drive circuits considerably. The HFE4080-32X-XBA is designed to be used with inexpensive silicon or gallium arsenide detectors, but excellent performance can also be achieved with some indium gallium arsenide detectors. The low drive current requirement of the HFE4080-32XXBA makes direct drive from PECL or ECL logic gates feasible and eases driver design.
