Fiber Optic Transmitter OPF694 Series OPF694 Series * * * * * Low Cost 850 nm LED technology High thermal stability High optical coupling efficiency to multimode fiber Metal ST* style receptacle Industrial temperature range The OPF694 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 either 50/125m or 62.5/125m diameter multimode fiber. Two 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. Applications Industrial Ethernet equipment Copper-to-fiber media conversion Intra-system fiber optic links Video surveillance systems Typical Coupled Power IF = 100mA, 25C Fiber Size Type N.A.
