ML4079E
8 Channel | 56 GBd PAM4 & NRZ | 800G BERT
The ML4079E is a full featured 800G BERT that can be configured as eight channels of 23-29 and 46-58 GBaud PAM4 or 23 – 29 and 46 – 58 Gbps NRZ. The transmitters support all standard test patterns mandated by IEEE and OIF such as PRBS13Q, SSPRQ, PRBS31Q, etc. Additionally, the user may program the TX to output a userdefined pattern.
The ML4079E supports real hardware FEC, with the following FEC modes:
400G line KP4
100G line KP1
100G line KR1
Once the FEC is enabled, the user will be able to see the post-FEC BER which indicates the bit error rate after enabling FEC and the amount of errored bits being corrected in real time. In addition, the ML4079E supports transmitter and receiver equalization to overcome signal integrity impairments due to channel losses or reflections. This capability can also be used to optimize link performance and thus minimize power consumption.
