Description
The AddOn Q400G-4Q56G-AOC9M-AO is a high-performance 400GBase active optical cable designed for data center, cloud, and high-bandwidth networking environments. This MSA-compliant QSFP-DD to 4xQSFP56 breakout AOC operates over multi-mode fiber (MMF) with a maximum reach of 9 meters, delivering reliable 400Gbps connectivity. Engineered with PAM4 modulation and DSP-free CDR technology, it provides low-latency, high-efficiency data transmission with multi-data rate support up to 56.15 Gb/s per lane. Featuring low power consumption (7.6W on the 400G end and 2.3W on the 100G ends) and a single 3.3V power supply, this cable is ideal for high-density switch-to-server interconnects, NICs, and storage devices. Fully hot-pluggable, RoHS-compliant, CMIS 4.0 compatible, and TAA certified, it ensures seamless interoperability, scalability, and long-term reliability in next-generation networks.
