Anritsu adds PAM4 FEC symbol error detection to Signal Quality Analyzer-R MP1900A
Anritsu says it has expanded the Forward Error Correction (FEC) analysis capability of its 116-Gbps PAM4 Error Detector (ED) MU196040B module for its Signal Quality Analyzer-R MP1900A series bit error rate testers (BERTs). The new ED module enables the MP1900A to support real-time measurement of FEC symbol errors, an industry first according to Anritsu. The company sees the capability upgrade as a particular benefit to design engineers working on 400 Gigabit Ethernet (GbE) and 800GbE devices and optical transceivers.
The PAM ED now provides what Anritsu asserts is best-in-class input-sensitivity performance as well as the ability to detect FEC symbol errors based on the 400GbE FEC standard in real time. In addition to conventional BER, the MP1900A also supports jitter tolerance measurements for assessing FEC error correction performance in high-speed PAM4 signals.
Thus, engineers can monitor changes in bit errors and FEC symbol errors with changes in input amplitude and jitter conditions in real-time, concludes Anritsu. The capability enables engineers to evaluate when symbol error counts exceed the correction ability of the FEC. The enhanced FEC analysis function is compatible with software for automatic conventional jitter tolerance measurement, the MP1900A BERT now supports one-button jitter tolerance measurements based on whether error correction using FEC is possible.
