Anritsu Signal Quality Analyzer MP1900A with support for 400GbE transceiver 8-channel FEC tests

Click2Contact

Anritsu is now supporting FEC tests of 400GbE and next-generation 800GbE QSFP-DD and OSFP transceivers by adding PAM4 PPG 8-channel synchronous/FEC pattern-generation functions to the company’s Signal Quality Analyzer MP1900A series.

FEC is being adopted at data centres using PAM4 to implement faster and larger-capacity 400GbE, etc, communications with assured quality. In addition, there is also active development of four and eight multilanes as well as PAM4 technologies. As a result, transmission quality tests for QSFP-DD, OSFP, etc, optical modules urgently need techniques to confirm the degree of error correction using multilane FEC patterns with added jitter and ISI stress. Moreover, such measurements require a signal source for accurate control of the eight synchronised channels and the phase and patterns between channels.

The Signal Quality Analyzer MP1900A series Pulse Pattern Generator all-in-one BERT supports both generation of 400GbE PAM4-signal multichannel FEC patterns and jitter tolerance measurements. As well as supporting 1- and 4-channel patterns, 8-channel pattern synchronisation and FEC pattern generation functions have been added to this high-speed PAM4 BERT, supporting 8-lane transceivers for 400GbE communications.
