MCP1660-W01AE30 Cable DAC Copper Direct Attach Mellanox 400GbE QSFP-DD 1.5m

The Mellanox MCP1660-W01AE30 is a high-speed 400GbE Direct Attach Copper (DAC) cable designed for data center switching and server connectivity. This QSFP-DD to QSFP-DD passive copper cable delivers reliable, low-latency links for top-of-rack, spine-leaf, and end-of-row architectures across Asia, Europe, Africa, and North America. With a 1.5 m length and 30 AWG wire gauge, it is ideal for short-reach connections inside racks or between adjacent racks, helping distributors, small and medium integrators, and end users build dense, cost-effective 400G infrastructure.

The MCP1660-W01AE30 uses QSFP-DD male connectors on both ends, ensuring seamless integration with NVIDIA Networking (Mellanox) 400GbE switches and high-performance servers. As a passive copper cable assembly, it does not require additional power or complex configuration, which simplifies deployment and reduces failure points in high-traffic environments. For integrators, this helps speed up installation, while resellers can offer a robust, easy-to-stock option for standard 400GbE data center builds.

Operating at 400 Gb/s, the MCP1660-W01AE30 supports data center interconnect and high-speed switch-to-switch and switch-to-server links where throughput and latency are critical. The 1.5 m length keeps signal paths short, helping maintain signal integrity while avoiding unnecessary cable slack. Its passive copper design also supports lower latency compared with optical transceivers, which is important for time-sensitive workloads such as financial trading, real-time analytics, and research computing.

Across global regions, many mid-size enterprises and cloud providers look for straightforward 400GbE connectivity without added complexity. The Mellanox MCP1660-W01AE30 fits these needs with predictable performance, standardized QSFP-DD interfaces, and a robust construction suitable for high-density racks. Distributors can confidently position this cable as a dependable accessory for NVIDIA Networking 400G platforms, while end customers benefit from stable bandwidth for virtualization clusters, storage networks, and AI-ready server farms, all with a simple plug-and-play experience.
