18 September 1997 HFE4218 HFE4218 High Power Fiber Optic LED for Ethernet Applications FEATURES · Industry standard ST¨ fiber connector · 850 nm GaAIAs LED · Designed to meet IEEE Ethernet standard 802.3 FOIRL 10Base-FB/FL specification · High reliability construction · Popular Fiber DIP package · Wave solderable · Non-conductive plastic ST¨ barrel FIBER201 FIBER201.TIF DESCRIPTION The HFE4218 HFE4218 series is a GaAlAs 850 nanometer LED designed to meet IEEE Ethernet 802.3 specifications. The LED component is electrically isolated from the connector. The mechanical construction uses a high reliability ST¨ Fiber-Dip fiber optic connector/housing designed for easy mounting on printed circuit boards without the need for additional hardware. This connector accepts a wide variety of fiber sizes (50/125 micron through 100/140 micron) and is designed to meet the Ethernet 802.3 specification utilizing a 62.5/125 micron diameter fiber cable. The LED is designed to be driven with a 50% duty cycle at 100 mA (-311)/60 mA (-312) peak forward current for the electrical input signal.

HFE4218 HFE4218 is tested using a 10 meter length of 62.5/125 µm dia. fiber cable. Actual coupled power values may vary due to mechanical alignment tolerances/procedures. ABSOLUTE MAXIMUM RATINGS (25¡C Free-Air Temperature unless otherwise noted) Storage temperature -55 to +85¡C Case operating temperature -40 to +85¡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.
