Description:

The OPF372 family fiber optic transmitters are high performance devices packaged for data communication links. This

transmitter is an 850nm GaAlAs LED and is specifically designed to efficiently launch optical power into fibers ranging in size

from 50/125µm up to 200/300µm diameter fiber. Multiple power ranges with upper and lower limits are offered which

allows the designer to select a device best suited for the application.

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.

The mechanical design of this packaged is intended for PC Board or panel mounting. It is shipped with a lock washer, jam

nut, 2 #2-56 screws, and a protective dust cap.
