For coherent transmission test Keysight offers instruments for the generation and analysis of complex modulated optical signals. Multichannel arbitrary waveform generators are typically used to synthesize complex modulated signals.

Optical modulation analyzers provide detailed insights into the complex modulated optical signals at the physical layer to determine signal quality or evaluate components that are designed for IQ modulation and demodulation.

Keysight offers the widest range of optical modulation analysis and synthesis instruments for testing up to 1 Tb/s – for your current and future needs.

Coherent Optical Component Test Enables 1.2 Terabit Applications

Using Keysight’s state-of-the-art test equipment, NeoPhotonics successfully validated the performance of its 64 GBaud components, including its new 400ZR COSA, almost one year before the availability of DSP silicon for the transceivers. Without Keysight equipment, NeoPhotonics had no way of testing and assessing the performance of their components.
