NVIDIA Mellanox MCP1600-E003E26 100Gb/s QSFP28 DAC Cable 3m

• InfiniBand EDR fabric interconnects: Provides up to 100Gb/s passive copper connectivity for supported EDR infrastructure, helping HPC and data-center teams establish high-bandwidth links without optical cabling. 
• HPC cluster networking: Connects supported high-performance computing nodes and fabric infrastructure over short distances, supporting bandwidth-intensive workloads where efficient interconnects are important.
• AI and accelerated computing infrastructure: Provides a high-speed physical interconnect option for supported NVIDIA/Mellanox environments where accelerator and compute infrastructure requires high-throughput fabric connectivity.
• Data-center rack connectivity: The 3m length supports short-reach connections within dense equipment layouts while avoiding unnecessary excess cable length.
• Switch-to-adapter connections: Suitable for supported QSFP28 InfiniBand EDR connections between network adapters and switching infrastructure.
• High-density fabric deployments: The QSFP28 form factor provides four copper pairs operating at up to 25Gb/s per pair, delivering aggregate connectivity of up to 100Gb/s. 
• Power-conscious interconnect designs: Passive construction and a specified maximum power consumption of 0.1W make it appropriate where minimizing cable-related power draw is part of infrastructure planning. 
• Short-distance optical replacement: NVIDIA/Mellanox positions the MCP1600 family as a cost-effective alternative to fiber optics for InfiniBand 100Gb/s EDR applications, making it relevant where passive copper reach is sufficient. 

• Up to 100Gb/s data rate - Supports high-bandwidth InfiniBand EDR connectivity for demanding HPC and data-center workloads. 
• QSFP28 form factor - Provides a standardized high-density connector format for supported 100Gb/s fabric equipment, simplifying deployment in compatible infrastructure. 
• Four 25Gb/s copper pairs - Uses four high-speed copper pairs, each operating at up to 25Gb/s, to deliver aggregate bandwidth of up to 100Gb/s. 
• Passive direct-attach copper design - Eliminates active signal-processing electronics in the cable, making it a practical short-reach alternative to optical connectivity where the platform and distance support passive DAC operation. 
• 3-meter length - Provides a longer short-reach option than 0.5m, 1m, 1.5m, and 2m family variants, giving data-center teams more flexibility for rack-level equipment placement. 
• 26AWG construction - Uses the heavier-gauge cable specification associated with the 2.5m–5m MCP1600 family variants, supporting the defined mechanical design for longer passive-copper lengths. 
• 9.4 ± 0.4mm cable diameter - Gives cabling teams a defined physical dimension for rack routing, cable-management planning, and clearance assessment. 
• Defined bend-radius requirements - The 26AWG models specify a 47mm single-bend radius and 94mm repetitive/assembly bend radius, helping installers plan routing without exceeding the documented mechanical limits. 
• Low power consumption - Maximum specified power consumption is 0.1W, supporting power-conscious high-density infrastructure designs. 
• Hot-pluggable - Supports operational deployment and replacement workflows on compatible systems without requiring a permanent cable installation.
