Anritsu’s BERTWave MP2110A Sampling Oscilloscope shortens test times and cuts production costs for 100/200/400G optical modules and devices

Data traffic is growing exponentially due to the spread of flat-rate video streaming and other cloud services. Coping with this growth requires the deployment of transmission-equipment interfaces exceeding speeds of 100 Gbit/s, and 200/400 GbE interfaces have already started appearing. Moreover, this 200/400 GbE transmission format uses PAM4 technology, instead of the older NRZ technology. Although currently manufactured optical modules, such as CFP8, etc., use 26-Gbaud PAM4 optical signals, future mass-produced QSFP-DD and OSFP modules will use 53-Gbaud PAM4 optical signals.

Responding to this, Anritsu has announced the start of new firmware downloads available for the BERTWave MP2110A Sampling Oscilloscope. The new firmware will increase its PAM4 analysis function from 26 Gbaud to 53 Gbaud targeting production and inspection of optical modules. As well as featuring both high-sensitivity and high-speed measurements, with this release the MP2110A will now support the development and production-line inspection of next-generation QSFP-DD optical transceivers expected to be deployed in data centers, according to the company.

The BERTWave MP2110A is an all-in-one measuring instrument with built-in multi-channel Bit Error Rate Tester (BERT) and Sampling Oscilloscope, supporting BER measurements, Eye Mask tests, Eye pattern analyses, high sampling speed of 250 kSample/s and low-noise (3.4 μW) high-sensitivity O/E interface.

The BERT and Sampling Oscilloscope are required instruments for evaluating optical modules used by optical communications systems.

As well as NRZ technology, the MP2110A also supports PAM4 signal measurements including TDECQ, which enable all-in-one quality evaluations of optical modules at speeds from 25 to 400 G.

In addition, the MP2110A, thanks to its high-speed measurement and PAM4 analysis, will play a key role in improving optical module production-line productivity, said the firm.

Moreover, adding 53 Gbaud support for quality evaluation of next-generation optical modules claims to cut capital equipment renewal costs.

53Gbaud analysis function comes with PAM4 signal analysis software option MP2110A-095.
