Generic 400GBASE-XDR4 QSFP-DD PAM4 1310nm 2km DOM Optical Transceiver Module (SMF, 1310nm, 2km, MTP/MPO, DOM)


QDD-400G-XDR4 400G QSFP-DD optical module, namely QDD-4X100G-FR, or 400GBASE-DR4+, is designed to reach 2km distances over single-mode fiber (SMF). The 400 Gigabit Ethernet signal is carried over four parallel and independent Single Lambda 100G PAM4 lanes. 400GBASE-XDR4 uses MTP/MPO-12 connector, supporting breakout mode. It can be applied in the 4x100G breakout connectivity of QSFP-DD to QSFP28 100G-DR, 100G-FR, and 100G-LR.


QSFPTEK QDD-4X100G-FR 400GBASE-DR4+ module is compliant with QSFP-DD MSA, 100G Lambda MSA 400G-DR4+, CMIS 4.0, and IEEE 802.3bs and is mainly applied in 400G Ethernet, Data Center, and Cloud Networks.
