BlueLAN 400G QSFP-DD Cable de cobre de conexión directa, 2m, 26 AWG, Twinax pasivo, Azul, compatible con Mellanox MCP1660-W01AE30

High-density data centers demand reliable, low-latency links that won't break the budget. The BlueLAN MCP1660-W01AE30-BL QSFP-DD Direct Attach Copper (DAC) cable delivers 400 Gigabit Ethernet over a short 2-meter reach, eliminating the need for expensive optical transceivers in top-of-rack and adjacent-rack deployments. Engineered as a drop-in replacement for NVIDIA Mellanox MCP1660-W01AE30, this passive twinax assembly provides plug-and-play compatibility with QSFP-DD ports, ensuring seamless integration into existing InfiniBand and Ethernet fabrics.

Who is it for

Network architects, data center operators, and HPC cluster administrators who need to connect QSFP-DD switches, NICs, and storage nodes within the same rack or adjacent racks. It is ideal for spine-leaf architectures, high-performance computing clusters, and enterprise core networks where 400G density and low power consumption are critical. If you are deploying NVIDIA Mellanox Spectrum switches or ConnectX adapters, this cable is a cost-effective alternative to optical modules for short links.

Tips

For optimal performance, ensure both connected devices support QSFP-DD ports and 400G speeds. This DAC cable is best suited for short distances up to 2 meters; for longer runs, consider active optical cables or optical transceivers. The blue jacket aids in cable management and identification in dense environments.
