Agilent Technologies Inc. announced it has demonstrated fast complex-modulation optical interface rates. A joint team from Alcatel-Lucent Bell Labs and Agilent conducted experiments using Infiniium 90000 Q-Series oscilloscopes to transmit data over long-haul distances at a record interface rate.

The experiments relied on advanced detection systems and data analysis from Alcatel-Lucent Bell Labs and on the unmatched measurement performance of Agilent’s Infiniium 90000 Q-Series oscilloscopes to achieve PDM 16 QAM 1.28-terabit dual-carrier optical signaling.

The joint team synchronized two 63-GHz 90000 Q-Series oscilloscopes and used them as 4X analog-to-digital converters running at 160 GSa/s. The bandwidth combined with the measurement accuracy of the scopes enabled the experiments’ success.

The Agilent Infiniium 90000 Q-Series oscilloscopes, featuring 63 GHz of real-time bandwidth, were introduced in April 2012. The Infiniium 90000 Q-Series scopes feature the industry’s lowest noise floor, the highest probing bandwidth, and a comprehensive set of measurement-specific software applications.
