Description:
The OPF342 family fiber opc transmiers are high performance devices packaged for data communicaon links. This
transmier is an 850nm GaAlAs LED and is specifically designed to efficiently launch opcal power into fibers ranging in size
from 50/125µm up to 200/300µm diameter fiber. Mulple power ranges with upper and lower limits are offered which
allows the designer to select a device best suited for the applicaon.
This product’s combinaon of features including high speed and efficient coupled power makes it an ideal transmier for
integraon into all types of data communicaons equipment.
The mechanical design of this packaged is intended for PC Board or panel mounng. It is shipped with a lock washer, jam
nut, 2 #2-56 screws, and a protecve dust cap.
