Fiber Optic LAN Components HFE438x-521 SC Connectorized High Speed VCSEL 1.25Gbps 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 • Packaged with a photodetector LASER RADIATION AVOID EXPOSURE TO BEAM CLASS 3B LASER PRODUCT The HFE438x-521 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. The power monitor diode can be used with appropriate feedback control circuitry to set a maximum power level for each VCSEL. In addition, built-in power attenuation reduces the effective slope efficiency. These combined features simplify design for high data rate communication and eye safety. Packaged in a fiber receptacle sleeve, this high radiance 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 HFE438x-521 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 HFE438x-521 is a prealigned and focused fiber optic transmitter designed to interface with 50/125 and µm multimode fiber.
