Fibre Optic LAN Components VCSEL + BMPD HFE4083-322/XBA FEATURES • High speed low cost VCSEL. • Industry standard ST-LP fibre connector. • Designed for drive currents between 5 and 15mA Optimised for low temperature dependence The HFE4083-322/XBA is a high-performance 850nm VCSEL vertical cavity surface emitting laser packaged for high speed communications. This product combines all the performance advantages of the VCSEL with a custom designed power monitor diode. The power monitor diode can be used with appropriate feedback control circuitry to set a maximum power level for each VCSEL, simplifying design for high data rate communication and eye safety. 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 fibre applications. APPLICATION The HFE4083-322/XBA is a high radiance VCSEL packaged in an ST PCB mounting housing. The ST optical port enables efficient and convenient coupling of the optical power into a fibre network. The component produces a circularly symmetric, narrow divergence beam. The HFE4083-322/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 of the HFE4083-322/XBA makes direct drive from PECL or ECL logic gates feasible and eases driver design.
