Four-channel scope delivers BER test for 100G/400G optical modules

A four-channel (4ch) sampling oscilloscope option for the BERTWave MP2110A has been announced by Anritsu, enabling integration of multi-channel oscilloscope and BERT (Bit Error Rate Tester) in an-all-in-one unit. Backbone networks and data centres increasingly use 100G Ethernet to meet anticipated traffic demand for services such as 5G and are considering implementing 400G Ethernet.

The functionality of the optical modules used in these networks includes NRZ/PAM4 signaling, multiple channels, and different wavelengths, which previously required expensive high-performance test systems. The pressure to reduce pricing requires more cost-effective test solutions that retain flexibility to support future technologies.

The new 4ch oscilloscope option halves the unit cost per channel, while maintaining the same performance, enabling manufacturers to remain price-competitive.

With genuine multichannel support in hardware as well as software, the new oscilloscope option enables high-efficiency measurement, not only of multichannel modules, but also of multiple single channel modules for high-usability evaluation environments.

The 4ch option offers a high-performance, economical, all-in-one instrument configuration for combined 1/2/4 channel oscilloscope and BERT, making it the ideal, flexible and cost effective test solution for both development and manufacturing applications.
