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.

N4391C

N4391C Optical Modulation Analyzer

Starting from

The N4391C optical modulation analyzer consists of a UXR real-time oscilloscope and a calibrated coherent optical receiver. Featuring full bandwidth upgradability, you can keep pace with your roadmap in the evolution of symbol rate classes for transceivers for 800 Gb/s, 1.2 Tb/s to 1.6 Tb/s used in the DCI (Data Center Interconnect). A new O-band solution enables coherent signal and device testing in the emerging 1.3 µm wavelength band for intra-datacenter interconnect use.
