Fiber Optic Transmitter OPF370 Series OPF370 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 The OPF370 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 50/125m up to 200/300m 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 products 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 I = 100mA, 25C F Fiber Size Type N.A.
