NVIDIA/Mellanox MCA7J65-N005 Compatible 5m (16ft) 800G Twin-port OSFP Finned Top to 2x400Gb/s QSFP112 Flat Top Breakout Active Copper Cable
NADDOD O2Q112-800G-AC5 is an 800Gb/s Twin-port OSFP (Octal Small Form-factor Pluggable) Finned Top to 2x 400Gb/s QSFP112 (Quad Small Form-factor Pluggable 112G) Flat Top Active Copper Copper (ACC) dual breakout (aka splitter) cable for Ethernet networking. The switch end OSFP has a finned top for additional cooling and the QSFP112 adapter end is flat topped and uses riding heat sinks on the OSFP cage. The ACC contains eight high-speed electrical copper pairs, each operating at data rates of up to 100Gb/s using 100G-PAM4 modulation. The “active” term refers to the passive copper cable with an equalizer integrated circuit to extend the length to 4 and 5-meters.
In a 128-node AI cluster, the hybrid interconnection solution (single-mode optical modules + DAC) saves over 20% in deployment costs and ~21.6% in total power consumption vs. an multi-mode optical modules solution. It eases cooling pressure of switches, cuts data center power costs, and DAC’s near-zero power optimizes PUE—building green, sustainable computing infrastructure while meeting interconnection needs.
