They are compliant with the QSFP-DD MSA and with IEEE 802.3cn 200GBASE-ER4 specification. Digital diagnostics functions are available via the I2C interface as specified by CMIS V4.0. These modules can convert 8 channels of 25Gbps (NRZ) electrical input data to 4 channels of 50Gbps (PAM4) optical signal, and also can convert 4 channels of 50Gbps (PAM4) optical signal to 8 channels of 25Gbps (NRZ) electrical output data. And these modules incorporate FIBERSTAMP Technologies proven circuit and EML technology to provide reliable long life, high performance, and consistent service.
