Description
The AddOn Q400G-4Q56G-AOC3M-AO is a high-performance 400GBase active optical cable designed to deliver reliable, low-latency connectivity between QSFP-DD and 4xQSFP56 ports in next-generation data center and enterprise networks. Operating over multi-mode fiber (MMF) with a maximum reach of 3 meters, this cable uses PAM4 modulation to achieve data rates up to 56.15 Gb/s per lane, ensuring high-bandwidth, high-density interconnects for switches, servers, storage, and network interface cards.
Built to meet MSA and IEEE 802.3cm standards, it supports CMIS 4.0 and features DSP-free CDR technology for minimal latency and optimal signal integrity. The cable is hot-pluggable, LSZH-rated, RoHS compliant, and TAA compliant — making it ideal for government and enterprise environments requiring Trade Agreements Act compliance. Each unit is uniquely serialized, rigorously tested for data traffic and application performance, and backed by AddOn’s limited lifetime warranty.
