| Fiber Optic Transmitter OPF670 Series Features: * * * * * Low cost 850 nm LED technology Low cost TO package with electrically isolated plastic cap High thermal stability High optical coupling efficiency to multimode fiber Industrial temperature range Description: The OPF670 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 50/125m or 62.5/125m diameter multimode fiber. Three power ranges are offered, which allows the designer to select a device best suited for the application. The OPF670 is offered a low cost TO package with a plastic lens cap. The device is designed to be active aligned into a connector receptacle. Applications: * * * * Industrial Ethernet equipment Copper-to-fiber media conversion Intra-system fiber optic links Video surveillance systems OPF670-1 OPF670-2 OPF670-3 Part Number Ordering Information LED Peak Wavelength 850nm 850nm 850nm PT50 (dBm) Min -17.5 -16.0 -14.5 Tr, Tf (ns) Typ / Max 8.0/10.0 8.0/10.0 8.0/10.0 Pin Function 1 2 3 Anode Cathode Not Connected RoHS OPTEK reserves the right to make changes at any time in order to improve design and to supply the best product possible.
