PBT8812/PBT4412/PBT8812B
112Gbps/ch Bit Error Ratio Tester
Nexustest 112Gbps/Ch Bit Error Ratio Tester PBT8812/PBT4412/PBT8812B is a high-performance bit error ratio tester (BERT) applied to high-speed serial signal error rate test, which can be used for physical layer characterization and consistency test. It covers emerging 200/400/800GbE and CEI-112G standards by virtue of support for 4-level pulse amplitude modulation (PAM4) signals with up to 57 Gbaud symbol rate (equivalent to 112Gbit/s), as well as non-return-to-zero (NRZ) signals.
