40Gbps QSFP+ DAC Cable , Plug-And-Play & Low Latency - Cisco Cables And Accessories

The Cisco QSFP-H40G-CU3M= is a high-performance 40Gbps QSFP+ Direct Attach Copper (DAC) cable, designed for short-distance, high-speed connectivity in data centers, enterprise networks, and high-performance computing environments. This plug-and-play solution eliminates the need for additional transceivers, reducing complexity and cost while delivering ultra-low latency for critical applications.

Key Features & Benefits

✔ 40Gbps High-Speed Data Transfer – Supports 40 Gigabit Ethernet, InfiniBand, and other high-bandwidth protocols.
✔ Plug-and-Play Operation – No external power or configuration required; simply connect to QSFP+ ports for instant deployment.
✔ Low Latency & High Reliability – Passive copper design ensures minimal signal delay and stable performance.
✔ Cost-Effective Solution – More affordable than optical transceivers for short-reach connections (up to 3m).
✔ Cisco Certified & Compatible – Guaranteed interoperability with Cisco switches, routers, and servers (e.g., Nexus 9000, UCS).
✔ Durable & Flexible – High-quality shielded copper cable with bend-resistant design for easy cable management.

Technical Specifications

Ideal Use Cases

• Data Center Interconnects (switch-to-switch, switch-to-server)

• High-Frequency Trading (HFT) & low-latency applications

• Cloud Computing & Virtualization environments

• Storage Area Networks (SAN) & High-Performance Computing (HPC)

For longer distances, consider Cisco QSFP+ optical transceivers (e.g., QSFP-40G-SR4) with fiber cables.
