200GBASE-FR4 500m QSFP56 Optical Transceiver FTCC1122E2PCL CWDM EML Optical Module Original

On 200G QSFP-DD PAM4 is enabled by DSP (digital signal processor) that acts like a gear box to convert 8 electrical signal channels to 4 optical signal channels. Electrical signal interface can be 25 Gbps NRZ or 50 Gbps PAM4 and after passing through DSP Transceiver Optical signal is 25Gbps PAM4 and 50 Gbps PAM4 respectively. Thus, 200G QSFP-DD transceivers can have 8 x 25 Gbps or 4 x 50 Gbps optical channels. The number of optical channels is shown at the end of Industry Name and is different per module type. For example, 400GBASE-SR8 has 8x 50 Gbps PAM4 optical transmission channels.
