HFE4020-313/XXX Fiber Optic LED FEATURES • Power out designed for drive currents between 10 and 100 mA • Wave solderable • Optimized for linear optical output with drive currents between 10 mA and 100 mA • High speed 85 MHz • Mounting options SMA single hole ST single hole SMA PCB ST PCB SMA 4 hole DESCRIPTION The HFE4020-313/XXX is a high radiance GaAlAs 850 nanometer LED optimized for coupling into small fiber core diameters at a forward current of 10 to 100 mA. The patented "Caprock" LED chip combines high power coupling with wide bandwidth. The peak wavelength is matched for use with Honeywell silicon fiber optic detectors and receivers. When the HFE4020-313/XXX is used at elevated temperatures, thermal resistance must be taken into consideration. APPLICATION The HFE4020-313/XXX is a high radiance LED packaged in a fiber optic connector that aligns the optical axis of the base component to the axis of the optical fiber. Data rates can vary from DC to above 85 MHz depending upon component application. The LED converts electrical current into optical power that can be used in fiber optic communications. As the current varies typically from 10 to 100 mA , the light intensity increases proportionally. The HFE4020-313/XXX LED is designed to give high fiber coupled power high radiance into a standard fiber optic cable . In order to enhance the light being sent into a fiber optic cable, a mm diameter glass microlens is placed over the "Caprock" junction. The microlens collimates the light, increasing the intensity directed toward a fiber optic cable. This creates a "SWEET SPOT" of power, allowing greater power to be launched into standard fiber optic cables. Honeywell reserves the right to make changes in order to improve design and supply the best products possible.
