Teledyne LeCroy and Coherent Solutions showcase 64QAM 56GBaud test platform

Teledyne LeCroy and Coherent Solutions have demonstrated their ability to offer a test and measurements solution in coherent generation and detection of single carrier 64QAM signals. The demonstration took place at OFC 2017 in Los Angeles, CA, USA.

The platform incorporates the Coherent Solutions’ IQTransmitter with 40GHz of bandwidth and format independent, autobias controller (ABC). Teledyne LeCroy’s 65GHz LabMaster 10-65Zi-A high-bandwidth real-time oscilloscope combines with the 70GHz IQS70 coherent optical receiver and Optical-LinQ integrated OMA software to characterize the modulated optical signal.

Coherent Solutions’ IQTransmitter offers 40GHz of RF bandwidth and incorporates it’s 2nd generation modulator Automatic Bias Control (ABC) circuitry, which provides pattern-independent bias control for the investigation of higher-order modulation formats such as 64QAM.

The 40GHz IQTransmitter provides a stable, coherently modulated optical signal for component and system characterization. The automatic bias control is also available in a separate benchtop instrument, the IQABC, which can be use with Lithium Niobate, Indium Phosphide and silicon modulators.

The 70GHz bandwidth IQS70 Coherent Optical Receiver integrates seamlessly with the LabMaster 10Zi-A oscilloscope and OpticalLinQ software, delivering a complete optical modulation analysis package.
