Optical to Electrical Converter by Keysight Technologies

Note: Your Quotation Request will be directed to Keysight Technologies.

The N7005A from Keysight Technologies is an Optical to Electrical Converter that operates from 1250 to 1600 nm. It features a high-sensitivity DC-coupled photodetector module which is designed for direct optical-to-electrical conversion of the signals into an infiniium real-time oscilloscope. The converter can handle linear input power from 4 to 8 mW with a conversion gain from 72 to 85 V/W. It uses measured S-parameter data for an optimized correction filter, which is then used to flatten the frequency response for a more accurate measurement.

The N7005A is interfaced with single-mode 9/125 µm optical fiber at the input and a 1.85 mm female connector at the output and is used as a fully-integrated optical front-end solution for infiniium real-time oscilloscopes.
