Descripon:
The OPF350A ber opc transmier is a high performance device packaged for data communicaon links. This transmier
is an 850 nm GaAlAs LED and is specically designed to eciently launch opcal power into bers ranging in size from
50/125µm up to 200/300µm diameter ber. Mulple power ranges with upper and lower limits are oered which allows
the designer to select a device best suited for the applicaon.
This product’s combinaon of features including high speed and ecient coupled power makes it an ideal transmier for
integraon into all types of data communicaons equipment.
Applicaons:
• Power generaon communicaon
• Industrial Ethernet equipment
• Copper-to-ber media conversion
• Intra-system ber opc links
• Video surveillance systems
Features:
• 850 nm LED technology
• TO-18 plasc clear-cap package
• Electrically isolated plasc cap package
• High thermal stability
• High opcal coupling eciency to mulmode ber
• Industrial temperature range

Notes:
1. Maximum of 5 seconds with soldering iron. Duraon can be extended to 10 seconds when ow soldering. RMA ux is
recommended.
2. De-rate linearly at 1.0mA /°C above 25°C .
3. The component must be acvely aligned into the mang ber cable assembly to achieve opmal performance.
4. No Pre-bias.
5. All Optek ber opc LED products are subjected to 100% burn-in as part of its quality control process. The burn-in con-
dions are 96 hours at 100mA drive current and 25°C ambient temperature.
