AddOn Q400G-4Q56G-AOC25M Compatible 400GBase-AOC QSFP-DD to 4xQSFP56 PAM4 Active Optical Cable (850nm, MMF, 25m, TAA, MSA)

The AddOn Q400G-4Q56G-AOC25M is a high-performance 400GBase Active Optical Cable (AOC) designed for next-generation data center interconnects. This MSA and TAA compliant cable features a QSFP-DD connector on one end and four QSFP56 connectors on the other, enabling seamless 400G to 4x100G breakouts over a 25-meter active multi-mode fiber link. Operating at an 850nm wavelength, it leverages PAM4 modulation and supports multi-data rates up to 56.15 Gb/s per lane, ensuring low-latency, high-bandwidth connectivity.
Engineered for reliability and performance, the cable consumes just 7.6W on the 400G end and 2.3W on the 100G end (with all CDRs enabled) while maintaining hot-pluggable functionality and CMIS 4.0 compliance. With its LSZH-rated jacket, low power consumption, and robust performance across 0°C to 70°C operating temperatures, this active optical cable is ideal for data center switches, servers, storage systems, and NIC interconnect applications. Every unit is uniquely serialized, rigorously tested for full interoperability, and backed by AddOn’s limited lifetime warranty.
