Fiber Optic Transmitter OPF345 Series OPF345 Series • • • • • • Low Cost 850 nm LED technology Electrically isolated plastic cap package High thermal stability High optical coupling efficiency to multimode fiber Industrial temperature range 75 MHz Bandwidth The OPF345 series fiber optic transmitters are high performance devices packaged for data communication links. This transmitter is an 850 nm GaAlAs LED and is specifically designed to efficiently launch optical power into fibers ranging in size from 50/125µm up to 200/300µm diameter fiber. Multiple power ranges with upper and lower limits are offered which allows the designer to select a device best suited for the application. This product’s combination of features including high speed and efficient coupled power makes it an ideal transmitter for integration into all types of data communications equipment.
