400G QSFP-DD FR4 LC 2km CWDM4 Module



400G BASE QSFP-DD Transceiver Module

       In the current 400G optical transceiver modules, 8 channels of 53Gbps PAM4 (400G-SR8, FR8, LR8) or 4 channels of 106Gbps PAM4 (400G-DR4, FR4, LR4) are mainly used on the optical port side to achieve 400G

signal transmission, and they are used on the electrical port side.  8 channels of 53Gbps PAM4 electrical signals, using OSFP or QSFP-DD package form.  Both OSFP and QSFP-DD packages can provide 8 electrical signal interfaces.  

       In comparison, the QSFP-DD package size is smaller (similar to the QSFP28 package of the traditional 100G optical module), which is more suitable for data center applications; the OSFP package size is slightly larger, because it can provide more power consumption, so it is more suitable for telecommunications  application.
