The patented "Caprock"™ LED chip bines 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 ponent to the axis of the optical fiber. Data rates can vary from DC to above 85 MHz depending upon ponent application. The LED converts electrical current into optical power that can be used in fiber optic munications. As the current varies (typically from 10 to 100 m A), 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 0.30 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. ..
