Fiber Optic LAN Components High Speed VCSEL 2.5Gbps FEATURES • Designed for drive currents between 5 and 15 mA • Optimized for low dependence of electrical properties over temperature • High speed ≥1 GHz • Two different laser/ photodiode polarities • Attenuating coating also available • Packaged with a photodetector LASER RADIATION AVOID EXPOSURE TO BEAM CLASS 3B LASER PRODUCT HFE409x-322 The HFE409x-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 HFE409x-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 HFE409x-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 HFE409x-322 is designed to interface with 50/125 and 62.5/125 µm multimode fiber. They product circularly symmetric, non-astigmatic, narrow divergence beams that, with appropriate lensing, fiber couple all of the emitter power.

Operating power is set by the peak operating current IPEAK=IBIAS+IMODULATION. 2. Operation at temperatures outside the specified range may result in the threshold current exceeding the maximums defined in the electrooptical characteristics table. 3. Slope efficiency is defined as ∆Po/∆IF at a total power output of 1.8 mW. 4. Rise and fall times are sensitive to drive electronics 5. Beam divergence is defined as the total included angle between the 1/e2 intensity points. Beam divergence varies between 15deg and 30deg depending upon operating conditions. 30deg is expected to be worst case divergence. It is recommended that the optics be design for an NA of 0.3 6. To safeguard the VCSEL from current spike damage, short the VCSEL anode and cathode to each other during photodiode BVR verification testing. Additionally to safeguard the PIN photodiode, limit the photodiode reverse voltage in accordance with the absolute maximum rating. TYPICAL PERFORMANCE CURVES Typica l I O P , P O P Threshold Current vs. Temperature: Threshold current varies parabolically with temperature; thus it can be nearly constant for a limited temperature range.

NOTICE The inherent design of this component causes it to be sensitive to electrostatic discharge (ESD). To prevent ESDinduced damage and/or degradation to equipment, take normal ESD precautions when handling this product. Emission Intensity DANGER FW HM of e nve lope typica lly < 0.5 nm The VCSEL is a class IIIb laser and should be treated as a potential eye hazard. Due to the size of the component, the applicable warning logotype, aperture label, and certification/ identification label cannot be placed on the component itself. These labels can be found on the individual envelope in which the VCSEL unit is packaged, or attached to the shipping package.
