Optical to Electrical Converters
Features:• 400 nm to 1700 nm wavelengths• Battery or External AC Operation• Bandwidth to 20 GHz• Compact Size
The TIA-525, 527 and 952 series have BNC outputs fordirect connection to your oscilloscope or digitizer. TheTIA-1200, 2000 and 3000 use a type K SMA female
output connector. The TIA525 offers a free space option. Patch cords and adapters can be supplied to matewith various fiber optic connectors. The TIA-525 and 527
have dual power capability, battery and external universal power supply.
