Accelerating TDECQ analysis with parallel data acquisition
Testing the production performance of 800G optical transceivers requires measuring essential specifications and validating them with compliance standards. Manufacturing test programs make pass / fail decisions based on as few measurements as possible to keep throughput high. Transmitter dispersion and eye closure quaternary (TDECQ) aggregates many transmitter attributes into a single metric, which determines transmitter system performance and identifies imperfections.
Testing optical transceivers' performance requires an optical oscilloscope. Production testing focuses on efficiently acquiring and analyzing TDECQ measurements and determining whether the module passes or fails conformance specifications. High accuracy and throughput are essential to keeping manufacturing costs low, so parallel acquisition and analysis help reduce test time. High-bandwidth oscilloscopes with extremely low jitter and noise are necessary for measuring high-speed, low-margin 112 Gb/s and 224 Gb/s lane PAM4 signals.
800G optical transceiver manufacturing test solution
High-throughput optical transceiver performance testing during production requires efficiently acquiring and analyzing TDECQ measurements with optical oscilloscopes. The Keysight 800G optical transceiver manufacturing test solution uses high-bandwidth, low-noise DCA-M sampling oscilloscopes and Keysight FlexOTO software to run data acquisition and TDECQ analysis in parallel. Parallel processing optimizes instrument utilization to eliminate idle time and double throughput while enabling developers to establish pass / fail criteria for manufacturing quality control.
