Description
The AddOn Q400G-4Q56G-AOC15M-AO is a MSA and TAA compliant 400GBase-AOC QSFP-DD to 4xQSFP56 active optical cable designed for high-performance data center interconnects. Operating over multi-mode fiber (MMF) with a maximum reach of 15 meters, this cable supports PAM4 modulation and multi-data rates up to 56.15 Gb/s per lane, delivering exceptional throughput and low latency.
Engineered with DSP-free electronics-based CDR, the Q400G-4Q56G-AOC15M-AO offers low power consumption (7.6W on the 400G end and 2.3W on the 100G ends) and hot-pluggable connectivity, making it ideal for high-density applications such as switches, servers, storage systems, and NIC adapters. Compliant with IEEE 802.3cm and CMIS 3.0, this cable ensures seamless interoperability and reliability in demanding 400G Ethernet environments. Each unit is uniquely serialized, thoroughly tested for data traffic and application compatibility, and backed by AddOn’s limited lifetime warranty.
