Description
Absolute Maximum Ratings (TA = 25° C unless otherwise noted)
The OPF693 series fiber optic transmitters are high performance 850nm LED packaged for data communication
links. Two power ranges are offered which allows the
designer to select a device best suited for the application.
Storage Temperature
This product’s combination of features including high
speed and efficient coupled power makes it an ideal
transmitter for integration into all types of data communications equipment.
