Upgraded MP2110A Sampling Oscilloscope PAM4 Evaluation Functions | Electronics Maker

Standards-Compliant Measurement of PAM4 Signals at Electrical I/F of 50 to 400G Optical Modules

July21, 2021 –Anritsu Corporation (President Hirokazu Hamada) is pleased to announce the release of its Signal Processing Software Option-098 adding upgraded functions for evaluating PAM4*1 differential electrical signals to the BERTWaveSampling Oscilloscope MP2110A.

This new option supports standards-compliant measurement of IEEE802.3 optical-module*2 electrical interfaces to facilitate faster communications at data centers and mobile networksby upgrading evaluation efficiency for 50 to 400G optical modules using PAM4 technology.

Development Background

Data centers are currently switching to PAM4 optical modules to cope with large increases in communications traffic on mobile networks.Additionally, in line with the need for easier configuration of flexible networks, PAM4 optical modules for communicationssupport many more communications speeds ranging from 50 to 800 Gbit/s than the conventionalNRZ*3 technology.

Optical modules are devices supporting long-distance communications by converting electrical signals of network equipment to optical signals. With conventional optical modules using NRZ technology, multivendor interconnectivity validation of the optical-interface side connections between equipment was regarded as important while close inspection of the interconnectivity of electrical interfaces was seen as unnecessary. However, with speed increases using PAM4 optical modules supporting different speeds, the various module types must also be supported at the equipment side. Furthermore,under the conventional system, network equipment and optical modules were procured from the same vendor, but the current trend to help cost-cutting is to procure equipment and modules from different vendors.

In these circumstances, interconnectivity must be assured not only between interfaces at the optical side but also at the electrical side.Assuring this interconnectivity requires strict evaluation based on the IEEE802.3PHY-layer standards.

To meet these upgraded interconnectivity requirements,while continuing to support PAM4 optical interface measurements, Anritsu has now added support for measurement of IEEE 802.3 PAM4 electrical interfaces to its popular MP2110A used by many makers as a sampling oscilloscope for manufacturing optical modules.

Product Outline

The BERTWave MP2110A is an all-in-one instrument combining a sampling oscilloscope for evaluating communication-signal waveforms and a BERT for measuring bit error rates.Various upgrade options are available for customizing the number of sampling-oscilloscope channels, etc., to configure a cost-effective test environment matching requirements. Fast, all-at-once and parallel measurement of four channels assures high production-line throughput.

Adding this newly released Option-098 adds new support for measurement of PAM4 electrical interfaces to the current support forthe various IEEE802.3PAM4 optical modules now on the market.Measurement using the IEEE 802.3 digital filter and equalizer is also supported.Moreover, the new Embedding/De-embedding function*4 facilitates calibration of the measurement environment, including cables, etc.Installing the built-in Clock Recovery Option-054 permits configuration of a trigger-signal-free measurement environment.
