OPF694-2 Features:  Low Cost 850 nm LED technology  High thermal stability  High optical coupling efficiency to multimode fiber  Metal ST* style receptacle  Industrial temperature range Description: The OPF694-2 fiber optic transmitter is a high performance device packaged for data communication links. This transmitter is an 850 nm GaAlAs LED and is specifically designed to efficiently launch optical power into either 50/125µm or 62.5/125µm 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. Applications:  Industrial Ethernet equipment  Copper-to-fiber media conversion  Intra-system fiber optic links Typical Coupled Power I = 100mA, 25°C F Fiber Size Type N.A.
