NADDOD 400G breakout InfiniBand NDR direct attached copper cables(DAC) have an 8-channel twin-port OSFP end using a finned top form factor for use in Quantum-2 and Spectrum-4 switch cages. It provides connectivity between system units with an OSFP 400Gb/s connector on one side and two separate QSFP56 200Gb/s connectors on the other. NADDOD breakout DAC can provide lower latency in short-distance transmission, and it is suitable for a variety of application scenarios such as data centers, high-performance computing, and storage networks, especially in environments that require rapid deployment and flexible configuration.
