Fiber Optic LAN Components High Speed VCSEL 1.25Gbps HFE408x-322 FEATURES • Designed for drive currents between 5 and 15 mA • Optimized for low dependence of electrical properties over temperature • High speed GHz • Two different laser/ photodiode polarities • Attenuating coating also available • Packaged with a photodetector LASER RADIATION AVOID EXPOSURE TO BEAM CLASS 3B LASER PRODUCT The HFE408x-322 is a high-performance 850 nm VCSEL Vertical Cavity Surface-Emitting Laser packaged for high-speed data communications. This product combines all the performance advantages of the VCSEL with a custom designed power monitor diode, and is designed for ease of use by the module designer and manufacturer. 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. The HFE408x-322 is a high radiance VCSEL 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 HFE408x-322 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 makes direct drive from PECL Positive Emitter Coupled Logic or EML Emitter Coupled Logic gates possible and eases driver design. The HFE408x-322 is designed to interface with 50/125 and µm multimode fiber. They product circularly symmetric, non-astigmatic, narrow divergence beams that, with appropriate lensing, fiber couple all of the emitter power.
