Description
The AddOn Q400G-4Q56G-AOC5M-AO is a high-performance 400GBase active optical cable designed for data center interconnects, high-bandwidth networking, and 400G Ethernet applications. This MSA and TAA compliant QSFP-DD to 4xQSFP56 PAM4 cable operates over multi-mode fiber (MMF) with a maximum reach of 5 meters and supports multi-data rates up to 56.15 Gb/s per lane. Engineered with low-latency DSP-free CDR technology and PAM4 modulation, it ensures superior signal integrity, reduced power consumption, and optimal performance for switches, servers, storage systems, and NIC adapters. Each unit is programmed, uniquely serialized, and rigorously tested for data traffic and application compliance. The cable is hot-pluggable, LSZH-rated, RoHS compliant, and built to meet IEEE 802.3cm standards — all backed by AddOn’s limited lifetime warranty.
