Agilent Technologies Inc. (NYSE: A) today announced it has demonstrated the world’s fastest 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. In addition to the 63 GHz, enabled by RealEdge technology, the 90000 Q-Series oscilloscopes feature the highest effective number of bits (ENOB) at more than 5.5 at 33 GHz and the lowest interscope skew of less than 0.5 ps (standard deviation).
“State-of-the-art research requires state-of-the-art measurement,” said Jay Alexander, vice president and general manager of Agilent’s Oscilloscope Products Division. “The 90000 Q-Series oscilloscope delivers the most accurate measurements in the industry, and Agilent is proud to have played a key role in the groundbreaking research results at Alcatel-Lucent.”Agilent presented a paper at the IEEE Photonics Society Annual Meeting last fall, jointly with Alcatel-Lucent, that illustrates the breakthrough interface technology. The paper explains how teams from Agilent and Alcatel-Lucent set up and configured the world’s fastest interface rates and transmitted the signals over long-haul distances at high spectral efficiency. The collaborative experiment between Agilent and Alcatel-Lucent took place throughout 2012 and culminated in the paper: “1-Tb/s Dual-Carrier 80-GBaud PDM-16QAM WDM Transmission at 5.2 b/s/Hz over 3200 km.” 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.
