Anritsu Corporation have announced that visitors to ECOC 2018 (24-26 September, Rome) will be able to visit Stand #408 to see a demonstration of the new 64 Gbaud PAM4 Pulse Pattern Generator (PPG) installed on the Signal Quality Analyzer-R MP1900A series. The 64 Gbaud PAM4 PPG is a quality-evaluation test solution for measuring the bit error rate of the highest-level signals targeted for use by next-generation, high-speed 400/800GbE communications.
The MP1900A series is a high-performance Bit Error Rate Tester (BERT) that accurately measures communications equipment, next-generation high-speed electronic and optical devices, including those for M2M and IoT applications, and optical transceivers used in high-end servers.
The 53.125-Gbaud high-speed PAM4 transmission method under discussion to implement 400GbE implies several challenges: short pulse width per bit to 18.8 ps, one-third level transition amplitudes compared to NRZ signals, more complex detection which require much longer time and higher electrical potential accuracy.
Achieving device and module bit error rate testing with high accuracy and good reproducibility under these conditions requires an excellent reference signal source, and a measuring instrument with excellent high frequency and wideband performance, low noise and superior input sensitivity.
The demonstration will show how the Pulse Pattern Generator (PPG) can output NRZ and PAM4 signals at up to 64 Gbaud with the required high frequency and low-noise performance while achieving high speed Tr/Tf times (20 to 80%) of 8.5 ps (typical) and low intrinsic jitter of 170 fs (typical), reaching the highest-class performance of 64 Gbaud band PAM4 testers.
The 64 Gbaud PAM4 PPG will be key for evaluating DUT actual performance as well as in troubleshooting degraded performance due to the transmission path and hard-to-resolve problems such as inadequate performance margins, all helping to improve development and testing measurement efficiency.
The compact wideband-operation 64 Gbaud module installs easily in one slot of the MP1900A main unit while incorporating 4-level independent control Emphasis, PAM4 Code/Gray Code, symbol pattern editing, and other functions required for measuring PAM4 signals. This bit error rate test system with easy-to-use, all-in-one functions greatly simplifies measurement system configuration and parameter setting to help cut PAM4 device test times.
