TDECQ Part 1: Making Accurate and Repeatable Compliance Measurements

TDECQ Part 1: Making Accurate and Repeatable Compliance Measurements

TDECQ is the acronym used to describe “transmitter dispersion and eye closure quaternary”. This is a power penalty metric that describes how much extra power is required from a transmitter, relative to an ideal transmitter, to compensate for both non-ideal transmitter waveforms and the impact of chromatic dispersion. It is similar to the transmitter dispersion penalty (TDP) metric used in NRZ optical communications standards. It was developed in the IEEE 802.3bs standard and improved in the IEEE 802.3cd standard. It is a convenient way to specify the performance of a PAM4 transmitter, as it aggregates many transmitter attributes into a single metric, and the metric directly indicates the impact a transmitter’s imperfections will have on overall system-level performance.

Transmitter Test For Next-Gen Multimode Datacom Transceivers

Transmitter Test For Next-Gen Multimode Datacom Transceivers

The evolution of Capex and power consumption for networking is of significant concern to data center operators. Next-generation multimode pluggable modules are addressing this very critical issue. Keysight’s expert Dr. Hadrien Louchet first discusses how key performance metrics such as bit error rate, frame loss ratio can be measured with the A400GE-QDD multiport tester. He then focuses on a critical step of optical module validation, the optical transmitter test, and shows how Keysight combines the N1077B Multimode Optical/Electrical Clock Recovery and the N1092x Series of DCA-M sampling Oscilloscope to carry out accurate measurements on multimode design with a very low margin. As interoperability is and remains a must, accurate validation and conformance test solutions are necessary prior to the large-scale deployment of this low footprint technology.
