Fiber Optic LAN Components High Speed VCSEL 2.5Gbps HFE4090-321 FEATURES • Designed for drive currents between 5 and 15 mA • Optimized for low dependence of electrical properties over temperature www.DataSheet4U.com • High speed ≥1 GHz The HFE4090-321 is a high-performance 850 nm VCSEL (Vertical Cavity Surface-Emitting Laser) packaged for high-speed data communications. LASER RADIATION AVOID EXPOSURE TO BEAM CLASS 3B LASER PRODUCT The HFE4090-321 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 HFE4090-321 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 HFE4090-321 is designed to interface with 50/125 and 62.5/125 µm multimode fiber. It produces 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 electro-optical characteristics table. 3. Slope efficiency is defined as ∆Po/∆IF. 4. Rise and fall times are sensitive to drive electronics. Beam divergence is defined as the total included angle between the 1/e2 intensity points.

This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operations section for extended periods of time may affect reliability. TYPICAL PERFORMANCE CURVES www.DataSheet4U.com Emitted Power vs. Current: Power varies approximately linearly with current above threshold. 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.
