850nm Fast Ethernet Transceiver in 1 x 7 SMD Package Technical Data OPF5020 Features • • • • • • Small Form Factor surface mount package MT-RJ Receptacle Low cost 850 nm LED design Link distance up to 300m at 125Mbps Fully complies with the 100BASE-SX Fast Ethernet Standard (TIA-785) Single +5V power supply Description Absolute Maximum Ratings Storage Temperature Range Optek’s OPF5020 is a 125Mbps SFF transceiver for use in data communications applications. It utilizes a MT-RJ dual fiber receptacle which features a small size and intuitive latching mechanism design which allows for higher density implementations and easier end-user installation. Operating Temperature Range 260 °C for 10 Seconds Soldering Temperature (Vapor Phase Reflow) 235 °C for 30 Seconds Transmitter The receiver consists of a high speed PIN photodiode coupled to a low noise transimpedance amplifier. The receiver output is a low impedance analog source. The analog representation of the received optical input can be easily converted to PECL or TTL levels by external circuitry to be used in digital modes up to 125Mbps, NRZ. Supply Voltage Range The OPF5020 has been fully tested in accordance with Bellcore 468. See Application Bulletin 219 for full details. Optek Technology, Inc. 1215 West Crosby Road 0 to +70 °C Soldering Temperature (Soldering Iron) The transmitter is an 850 nm GaAlAs LED, configured for optimum transceiver performance when used in conjunction with a low-side driver. The coupling efficiency of the LED and optical system allows the device to be used at low current levels, reducing power consumption and increasing system reliability. Combining the OPF5020 with commercially available LED driver and post amplifier circuits results in a physical layer medium dependent (PMD) sub-layer for communication between nodes of a fiber network. Optek Application Bulletin 217 presents an example PMD design with typical receiver sensitivity of –30dBm at a BER of 2.5 x 10-10, operating full duplex with either a 223-1 or worst case FDDI data pattern. -40 to +85 °C Forward Input Current (DC) 100 mA Reverse Input Voltage 3.5 V Receiver -0.5 to 6V Output Current 25mA Notes: 1. All transmitters are subjected to 100% burn-in testing. Test conditions are 96 hours at 60 mA continuous current and 85°C ambient temperature. 2. This component is susceptible to damage from electrostatic discharge (ESD). Normal electronic component handling precautions should be observed during handling and assembly of this component to avoid damage or performance degradation. 3.
