Description
The AddOn Q400G-4Q56G-AOC7M-AO is a high-performance, MSA- and TAA-compliant 400GBase active optical cable (AOC) featuring a QSFP-DD to 4xQSFP56 PAM4 interface. Operating over multi-mode fiber with a maximum reach of 7 meters, this cable delivers low-latency, DSP-free data transmission with PAM4 modulation and supports data rates up to 56.15 Gb/s per lane. Designed for modern high-speed data center environments, it is fully hot-pluggable, CMIS 3.0 compliant, and built with LSZH-rated materials for improved safety. This cable is rigorously tested for interoperability, uniquely serialized, and backed by AddOn’s limited lifetime warranty — ensuring reliable connectivity for 400G Ethernet, switches, servers, storage systems, and NIC adapters.
