The QSFP DD LR8 400G is a high-performance 400Gbps QSFP-DD optical transceiver designed for long-range communication over single-mode fiber (SMF) up to 10 kilometers. Utilizing an 8-lane MUX/DEMUX architecture, the module converts 8 channels of 50Gbps (PAM4) electrical input into optical signals and multiplexes them into a single 400Gbps optical output. On the receiver side, the process is reversed to deliver 8 channels of 50Gbps (PAM4) electrical output. This module is compliant with IEEE 802.3bs (400GBASE-LR8), QSFP-DD MSA and CMIS4.0 specifications, making it suitable for Ethernet, data center interconnect, enterprise, and InfiniBand networking applications.
The module features dual LC connectors, operates with a single +3.3V power supply, and supports a temperature range from 0°C to 70°C. With a maximum power consumption of 14.5W, it ensures efficient operation for high-speed optical networks. Its precise optical characteristics include a lane wavelength range from 1272.55nm to 1310.19nm, high extinction ratios, and reliable sensitivity. Designed for scalability and robust performance, the CT-400G-QDD-LR8 meets the stringent requirements of modern optical communication networks while being fully RoHS compliant.
