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 50/125µm or 62.5/125µm 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.
