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 trans- mitter 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 de- signer 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 inte- gration into all types of data communications equipment. Applications ♦ Industrial Ethernet equipment ♦ Copper-to-fiber media conversion ♦ Intra-system fiber optic links ♦ Video surveillance systems Typical Coupled Power IF = 100mA, 25°C Fiber Size Type N.A.
