Mellanox MCA4J80-N005 400G QSFP-DD to 2x200G DAC Cable 5m

The Mellanox MCA4J80-N005 is a high-speed direct-attach cable (DAC) engineered for demanding data center and high-performance computing environments. This 5-meter passive copper cable delivers reliable connectivity between next-generation InfiniBand NDR infrastructure and legacy 200G endpoints, making it an ideal bridging solution for gradual network modernization.

Technical Specifications

• Connector Configuration: Single QSFP-DD (400G) to dual 200G ports
• Cable Length: 5 meters
• Technology: Passive copper DAC – no power consumption, minimal latency
• Data Rate: 400Gb/s aggregated throughput
• Protocol Support: Compatible with InfiniBand NDR 400G and Ethernet 400G standards

Key Benefits

As a passive solution, the MCA4J80-N005 eliminates the heat generation and power overhead associated with active optical or electronic devices. The 5-meter reach accommodates mid-range inter-cabinet and intra-row connectivity typical of modular data center architectures. The bifurcated design allows you to connect a single high-speed 400G source to two independent 200G endpoints, optimizing bandwidth utilization across heterogeneous infrastructure.

Mellanox DAC cables are engineered to stringent signal integrity standards, ensuring error-free transmission over copper at enterprise line rates. This makes the MCA4J80-N005 suitable for cluster interconnects, storage area networks, and hybrid compute fabrics where uptime and predictable performance are non-negotiable.

Part number MCA4J80-N005 simplifies procurement and integration into existing Mellanox-based deployments.
