Allen, TX – August 28, 2019 – Anritsu Corporation (President Hirokazu Hamada) is demonstrating its world-best PAM4 Error Detector (ED) supporting Bit Error Rate Tests at transmission rates up to 116 Gbit/s at the CIOE 2019 (China International Optoelectronic Exposition) held in Shenzhen, China, September 4-7, and the ECOC (European Conference on Optical Communications) Exhibition 2019 in Dublin, Ireland, September 23-25. With the world’s highest operation bit rate and Rx sensitivity, the new ED module for Anritsu’s popular Signal Quality Analyzer-R MP1900A Series PAM4 BERT supports high-accuracy BER measurement of PAM4 signals when combined with the previously released PAM4 Pattern Signal Generator.
Communications data traffic volumes are expected to grow with the spread of next-generation 5G mobile communications and cloud computing services. As a result, data centers supporting fast, large-capacity communications are examining speed increases to 400GbE using four 53.125-Gbaud PAM4 lanes, as well as future upgrades to 800GbE using eight PAM4 lanes.
Since the PAM4 method expresses 2 data bits with four amplitude levels, it has one-third the signal level difference of the NRZ method using two levels, requiring instruments for evaluating signal quality (integrity) to have much higher input sensitivity performance. Moreover, in addition to faster speeds, it is no longer possible to ignore the effect of losses from components, such as PC boards, cables, and connectors, in the transmission path on measured results. As a result, evaluating the true performance of the measurement target demands excellent fundamental performance such as sensitivity and frequency bandwidth, as well as solutions offering high-level integrated functions, including clock recovery and an equalizer, to compensate for the impact of loss.
Anritsu developed the ED with built-in clock recovery and equalizer functions to implement world-best high-sensitivity performance for PAM4 BER measurements. It allows manufacturers to conduct accurate BER evaluations of 400GbE communications equipment and devices.
MP1900A Series Outline
The Signal Quality Analyzer-R MP1900A Series PAM4 BERT is the market-leading Bit Error Rate Tester for communications speeds at 400G and above, and supports high-level signal generation and analysis. The demonstrated PAM4 ED module uses a unique InP semiconductor Rx circuit to achieve a sensitivity performance of 50 mV (typical) for a 58-baud PAM4 input. Additionally, the built-in clock recovery and equalizer functions, high sensitivity at upper operating frequency, and transmission path compensation support never-before-seen validation of BER measurement results. As a result, the true performance of optical transceiver modules and devices, as well as specification margins, can now be evaluated accurately.
