The patented "Caprock"TM LED chip combines high power coupling with wide bandwidth. The peak wavelength is matched for use with Honeywell silicon fiber optic detectors and receivers. The mechanical construction uses a small hole ST fiber connector / housing, designed for easy bulk-head mounting. OUTLINE DIMENSIONS in inches APPLICATION The HFE4050-01X/BAA HFE4050-01X/BAA is a high radiance LED packaged in an ST single hole mounting housing. 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 HFE4050-01X/BAA HFE4050-01X/BAA LED provides the maximum amount of radiance for the amount of forward current in the industry. A 0.25 mm diameter glass microlens over the "Caprock"TM junction collimates the light, increasing the intensity. Thus, greater power is directed toward standard fiber optic cables.

Actual coupled power values may vary due to alignment procedures and/or receptacle and fiber tolerances. 3. HFE4050-01X/BAA HFE4050-01X/BAA must be heat sinked for continuous I¸ > 100 mA operation for maximum reliability (i.e. mounted in a metal connector with thermally conductive epoxy). ABSOLUTE MAXIMUM RATINGS (25¡C Free-Air Temperature unless otherwise noted) Storage temperature -65 to + 150¡C Case operating temperature -55 to + 125¡C Lead solder temperature 260¡C , 10 s Continuous forward current (heat sinked) 100 mA Reverse voltage 1 V @ 10 µA Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods of time may affect reliability.

FIBER INTERFACE Honeywell LEDs are designed to interface with multimode fiber with sizes ranging from 50/125 to 200/230 microns. Honeywell performs final tests using 50/125 micron core fiber. All multimode fiber optic cables between 50/125 and 200/230 should operate with similar excellent performance. See table for typical powers. TYPICAL COUPLED POWER (µW/dBm) @ I¸=100 mA Dia.
