OPF694-1 TT Electronics

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 50/125m or 62.5/125m diameter multimode fiber. Two power ranges with upper and lower limits are oeff red 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, 25C F Fiber Size Type N.A.
