Anritsu released an FEC symbol capture function and Bathtub test capability for its 116-Gbit/s PAM4 Error Detector (ED) MU196040B, offering more functionality for developers of 400-GbE and 800-GbE devices. Installed in Anritsu’s flagship Signal Quality Analyzer-R MP1900A series, these functions can be downloaded from the MP1900A website.
PAM4 used in 400 GbE can be affected by noise and transmission path losses, making it difficult to achieve the previous level of error-free transmissions and requiring use of forward error correction (FEC) to address generated errors and maintain transmission quality. Consequently, there is an increasing need for quantitative measurement of jitter-related signal quality, such as jitter tolerance measurement for evaluating the performance of high-speed devices and transceivers for 400-GbE. To meet this need and support 400G network evolution, Anritsu added two features to its MP1900A - the FEC symbol capture function to evaluate FEC-based network elements, and the PAM4 Bathtub test capability.
The expanded MP1900A ED function determines if the errors can be corrected by FEC, and starts capturing data streams only when the burst errors exceed the FEC uncorrectable threshold. From the captured data, a user can discover what kind of data steam caused the uncorrectable burst errors. The scalable and modular MP1900A running embedded Windows 10 also functions as a bit-error rate tester (BERT) for various high-speed interfaces, including PCI Express Gen5 and USB4, using a full line of modules and application software.
