QSFP-DD 400G Duplex 1310nm 2km FR4 LC
This 400G QSFP-DD transceiver is designed for 400GBASE-FR4 Ethernet, data center, and switch/router interconnect applications. It supports data rates up to 106.25 Gbps per channel (PAM4 modulation), providing an aggregate bandwidth of 425 Gbps across four lanes. The module features a duplex LC optical interface, operates over single-mode fiber with a maximum link length of 2 km, and utilizes CWDM4 EML transmitters with PIN receivers for high-performance optical communication.
Fully QSFP-DD MSA and CMIS compliant, the transceiver supports 400G-FR4 technical specifications, consumes less than 10 W of power, and operates within a temperature range of 0 °C to +70 °C. It is hot-pluggable and RoHS compliant, making it ideal for high-capacity, energy-efficient network infrastructures in modern data centers and backbone systems.
