Low Cost 850 nm LED technology
Electrically isolated plastic cap package
High thermal stability
High optical coupling efficiency to multimode fiber
Industrial temperature range
The OPF370 series fiber optic transmitters are high performance devices packaged for data communication links. This transmitter is an 850 nm 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.

Notes:
1. Maximum of 5 seconds with soldering iron. Duration can be extended to 10 seconds when flow soldering. RMA flux is recommended.
2. De-rate linearly at 1.0mA /°C above 25°C .
3. The component must be actively aligned into the mating fiber cable assembly to achieve optimal performance.
4. No Pre-bias.
5. All Optek fiber optic LED products are subjected to 100% burn-in as part of its quality control process. The burn-in conditions are 96
hours at 100mA drive current and 25°C ambient temperature.
