Description
The AddOn Q400G-4Q56G-AOC30M-AO is a high-performance 400GBase active optical cable (AOC) featuring a QSFP-DD to 4xQSFP56 PAM4 breakout configuration. Designed for next-generation data center and cloud networking environments, this AOC delivers reliable 400Gbps connectivity over multi-mode fiber (MMF) with a maximum reach of 30 meters. It supports PAM4 modulation and multi-data rates up to 56.15 Gb/s per lane, ensuring optimal signal integrity and high-speed data transfer.
With low power consumption (7.6 W on the 400G end, 2.3 W on the 100G end), hot-pluggable design, and low-latency DSP-free CDR, it is ideal for use in switches, servers, NICs, and storage applications. This cable is MSA and CMIS 4.0 compliant, RoHS and TAA certified, and built with an LSZH-rated jacket for enhanced safety and performance. Every unit is programmed, serialized, and rigorously tested to ensure 100% compatibility and reliability in demanding enterprise and cloud infrastructure environments.
