Fiber Optic Transmitter OPF672 , OPF673 Series Features: • • • • • Low cost 850 nm LED technology High thermal stability High optical coupling efficiency to multimode fiber Standard and low profile metal ST* style receptacles Industrial temperature range OPF672 OPF673 Description: The OPF672 and OPF673 series fiber optic transmitters are high performance devices packaged for data communication links. These transmitters are an 850 nm GaAlAs LED and are specifically designed to efficiently launch optical power into either 50/125µm or 62.5/125µm diameter multimode fiber. Three power ranges with upper and lower limits are offered, which allows the designer to select a device best suited for the application. The OPF672 is offered a standard profile, metal ST receptacle and the OPF673 is offered in a low profile version. These products combination of features including high speed and efficient coupled power makes it an ideal transmitter for integration into all types of data communications equipment.
