Anritsu error detection module boosts evaluation of 400 GbE/800 GbE devices and transceivers
A new error detection module expands analysis capability in Anritsu’s signal quality analyser-R MP1900A series bit error rate testers by supporting real-time measurement of forward error symbols.
The 116 Gbit per second PAM4 MU196040B error detection module, aimed at helping design engineers to evaluate next-generation 400 GbE and 800 GbE high-speed devices and transceivers, features best-in-class input-sensitivity performance, as well as the real-time capability to detect forward error correction symbol errors based on the 400 GbE forward error correction standard. In addition to conventional bit error rate measurement, the MP1900A also supports jitter tolerance measurements for assessing error correction capability using forward error correction, as required by transmissions using high-speed PAM4 signals.
Engineers can monitor changes in bit errors and forward error correction symbol errors with changes in input amplitude and jitter conditions in real-time with the MP1900A. The aim is to quickly and reproducibly evaluate when symbol error counts exceed the correction ability of forward error correction. Since the new forward error correction analysis function is compatible with conventional jitter tolerance automatic measurement software, the MP1900A bit error rate tester supports one-button jitter tolerance measurements based on whether error correction using forward error correction is possible.
Evaluation of devices and transceivers supporting PAM4 requires jitter tolerance and sensitivity evaluations based on conventional bit error and error-free measurements, as well as measurement of error correction using forward error correction. Anritsu states that the MP1900A, with the new PAM4 ED module, meets these testing parameters.
The signal quality analyser-R MP1900A series consists of multichannel bit error rate measuring instruments. The modular bit error rate testers can inspect and verify next-generation network interfaces, such as 400 GbE and 800 GbE, as well as high-speed bus interfaces, such as PCI Express 4.0/5.0/6.0, USB3.2, USB4, and Thunderbolt.
In addition to more accurate bit error rate measurements, the MP1900A helps shorten development times for high-speed devices and transceivers.
