| MF431 Datacom, Telecom, General Purpose LED MF431 ST Applications * FDDI * ATM-SDH/SONET 155Mbps * Intra-Office Telecommunications * General Purpose Description This LED is designed for Datacom, Telecom and General Purpose Applications. It has a long wavelength LED for links up to 10 km at 125Mbps. It meets standards for FDDI (ANSI X3T9.5) and ATM155Mbps. The device is optimized for 62.5/125m fiber and actively aligned in an ST(R) receptacle. The MF432 PIN Photodiode is recommended as Receiver for this LED. Features ST Assembly * 1320nm Surface-Emitting LED * 125MHz Bandwidth * Designed for 62.5/125m Fiber * Aligned in ST(R) Receptacle * MTTF >1,000,000 hours Ordering Information PART # RECEPTACLE MF431 ST ST -40C to +85C MF431 Functional Diagram FIBER ANODE CASE DETECTOR CATHODE BOTTOM VIEW MF431 LED 13324.11 1997-04-01 10 Datacom, Telecom, General Purpose LED MF431 Absolute Maximum Ratings* Parameter Storage Temperature Operating Temperature (Fig 4) Electrical Power Dissipation (Fig 4) Continuous Forward Current (f10kHz) Peak Forward Current (duty cycle 50%, f1MHz) Reverse Voltage Soldering Temperature (Note 1) Symbol Tstg Top Ptot IF IFRM VR Tsld Min. -40 -40 Max. +85 +85 160 80 130 0.5 260 Units C C mW mA mA V C *Exceeding these values may cause permanent damage.
