OM4000 Optical Modulation Analyzer

From the Leader in Optical Modulation Analysis System Performance

The OM4245 uses coherent detection to acquire fiber signals carrying up to 80 GBaud, then analyzes both modulation and source properties using the power of DSP. It presents a rich library of results and graphical plots. Dynamic MATLAB integration provides the ultimate in analysis system customization and extensibility.

The OM4245 Coherent Optical Modulation Analyzer provides the ultimate flexibility in your system configuration by being tightly integrated with the DP070000SX Series 70 GHz real-time oscilloscopes and the DSA8300 Series 70 GHz equivalent-time oscilloscope.

For higher baud rates, the OM70000 Optical Modulation Test System can provide over 100GBaud of testing capability with a 70GHz Optical Receiver.
