WHY CHOOSE THIS PRODUCT?

• MCA4J80-N004 is a strong procurement choice when a 4-meter copper reach is required for 800Gb/s NDR InfiniBand connectivity. Its twin-port 2x400Gb/s architecture, OSFP interfaces, low latency, and 1.5W-per-end power profile make it well suited to dense AI and HPC fabrics while avoiding the higher complexity of optical connectivity where copper is appropriate.
