Fiber Optic Transmitter
OPF692, OPF693 Series
OPTEK reserves the right to make changes at any time in order to improve design and to supply the best product possible.
Applications
♦ Industrial Ethernet equipment
♦ Copper-to-fiber media conversion
♦ Intra-system fiber optic links
♦ Video surveillance systems
OPF692, OPF693 Series
• Low Cost 850 nm LED technology
• Popular ST® style receptacle
• Pre-tested with fiber to assure performance
• Component pre-mounted and ready to use
• 55MHz operation
The OPF692 and OPF693 fiber optic transmitters are high performance devices packaged for data communication links. The-
se transmitters are an 850nm GaAlAs LED and are 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 al-
lows the designer to select a device best suited for the application.
These products’ combination of features including high speed and efficient coupled power makes them ideal transmitters for
integration into all types of data communications equipment.
The mechanical design of these packages are intended for PC Board or panel mounting. They are shipped with a lock washer,
jam nut, 2 #2-56 screws, and a protective dust cap.
