Cisco QDD-400G-DR4-S Compatible 400GbE QSFP-DD DR4 1310nm 500m FEC SMF Optical Transceiver Moudle (PAM4, MTP/MPO, DDM, Commercial Temp)

Cisco QDD-400G-DR4-S transceiver is a single-mode, four-channel (DR4), QSFP-DD optical transceiver module designed for 400 Gigabit Ethernet (GbE) links on up to 500m of single mode fiber. NADDOD offers Cisco QDD-400G-DR4-S Compatible 400G QSFP-DD DR4 Optical module, which adopts a 1310nm EML transmitter type and PAM4 pulse amplitude modulation mode, by converting 8 input channels of 50Gb/s PAM4 electrical data to 4 channels of 100Gb/s PAM4 optical signals, using a nominal wavelength of 1310 nm, MTP/MPO-12 connector for 400Gb/s optical transmission. It is compliant with the QSFP-DD MSA, IEEE 802.3bs and 400GBASE-DR4. It is widely used in high-performance computing (HPC) networks, data centers, 400G Ethernet interconnect, enterprise core, and distribution layers, and service provider applications.
