ERM3040 Series NRZ/PAM4 BERT is a high-end BER for multi-channel PAM4 and NRZ applications in ERM series BER products. It is an ultra-small fully integrated high-performance BER, which can ensure maximum signal integrity while saving space, and is mainly suitable for current 100G/400G TOSA/ROSA component R&D and production testing as well as batch testing of optical modules.
