Description
The AddOn Q400G-4Q56G-AOC4M-AO is a high-performance 400GBase active optical cable designed for ultra-high-speed interconnects in modern data centers. This MSA and TAA compliant QSFP-DD to 4xQSFP56 breakout AOC operates over multi-mode fiber with a maximum reach of 4 meters at 850nm. It features PAM4 modulation and low-latency DSP-free electronics-based CDR, supporting multi-data rates up to 56.15 Gb/s per lane. Engineered for reliability and efficiency, it delivers low power consumption (7.6W on the 400G end and 2.3W on each 100G end) and supports CMIS 4.0. Fully hot-pluggable and RoHS compliant, this LSZH-rated AOC is ideal for high-density switch, server, storage, and NIC interconnects in next-generation Ethernet deployments.
