Features - - - - - - Small Form Factor surface mount package MT-RJ Receptacle Low cost 850 nm LED design Link distance up to 300m at 125Mbps Fully plies with the 100BASE-SX Fast Ethernet Standard (TIA-785) Single +5V power supply Technical Data Description Optek’s OPF5020 is a 125Mbps SFF transceiver for use in data munications applications. It utilizes a MT-RJ dual fiber receptacle which features a small size and intuitive latch.. ing mechanism design which allows for higher density implementations and easier end-user installation. The transmitter is an 850 nm Ga Al As 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. 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. bining the OPF5020 with mercially available LED driver and post amplifier circuits results in a physical layer medium dependent (PMD) sub-layer for munication between nodes of a fiber network. Optek Application Bulletin 217 presents an example PMD design with typical receiver sensitivity of - 30d Bm at a BER of 2.5 x 10-10, operating full duplex with either a 223-1 or worst case FDDI data pattern. The OPF5020 has been fully tested in accordance with Bellcore 468. See Application Bulletin 219 for full details.
