Description
The AddOn Q400G-4Q56G-AOC8M-AO is a high-performance 400GBase active optical cable designed to deliver reliable, high-speed data transmission for next-generation data center and enterprise networks. This MSA-compliant QSFP-DD to 4xQSFP56 PAM4 AOC operates over multi-mode fiber (MMF) with a maximum reach of 8 meters at a wavelength of 850nm, making it ideal for high-density switching, server interconnects, and NIC adapter applications. Featuring low-latency DSP-free CDR, PAM4 modulation, and support for data rates up to 56.15 Gb/s per lane, this active optical cable ensures optimal signal integrity and network performance. It offers low power consumption (7.6W on the 400G end, 2.3W on the 100G ends), hot-pluggable functionality, and LSZH-rated cable construction. Fully TAA compliant and rigorously tested for compatibility and reliability, this cable is backed by AddOn’s limited lifetime warranty — ensuring seamless integration and long-term network scalability.
