PAM4 error detector sets new lead for error rate tests
Operating at 116 Gbits per second, a PAM4 error detector (ED) module supports 116 Gbits per second bit error rate tests. The module for the Anritsu Signal Quality Analyzer-R MP1900A series is claimed to be the only instrument to achieve error-free measurement of PAM4 signals at 116Gbits per second with industry-best operation bit rates and high Rx sensitivity. Combined with Anritsu’s MP1900A series PAM4 pattern generator, the new module supports high-accuracy BER measurements of PAM4 signals, claims the company.
Data centres supporting rapid transmission of large volumes of traffic are switching to the 400GbE*3 communications standard using the 53.125-Gbaud PAM4 x four- lane method and are also investigating a future switch to 800GbE*4 using eight lanes. Next-generation 5G mobile communications and cloud services are also expected to increase data communications traffic.
To ensure evaluation of the genuine performance of the measured product, Anritsu has developed this ED with built-in clock recovery and equaliser to implement a PAM4 BER measuring instrument.
The Signal Quality Analyzer-R MP1900A is a bit error rate tester for communications speeds of 400G and faster, supporting high-speed signal generation and signal performance analysis.
The PAM4 ED MU196040B module has high-bandwidth and high-input-sensitivity Rx circuit to support error-free measurement of 100Gbits per second PAM4 input signals even at a low input amplitude of 36mV (typical). The built-in clock-recovery and equaliser functions support highly reproducible jitter and ISI stress tests of transceiver input circuits using an easily configured equipment set-up.
