High-Speed 100Gbps QSFP DAC Cable , Low Latency & Plug-And-Play –
Cisco Cables And Accessories
The Cisco QSFP-100G-CU3M= is a high-performance 100Gbps Direct
Attach Copper (DAC) cable designed for ultra-fast, low-latency
connections in data centers, enterprise networks, and
high-performance computing (HPC) environments. This passive
twinaxial cable offers a cost-effective, plug-and-play solution for
short-reach 100G Ethernet, eliminating the need for additional
transceivers or power consumption.
Key Features & Benefits
✔ 100Gbps High-Speed Data Transfer – Supports 100G-SR4, 100G-CWDM4,
and other 100G standards for seamless high-bandwidth networking.
✔ Ultra-Low Latency – Copper-based DAC ensures faster signal
transmission compared to optical solutions, ideal for
latency-sensitive applications like AI/ML, financial trading, and
cloud computing.
✔ Plug-and-Play Deployment – No external power or signal
conditioning required; simply connect between compatible Cisco
switches and servers.
✔ 3-Meter Reach – Optimized for short-distance connections within
racks or adjacent cabinets (e.g., switch-to-server, TOR
interconnects).
✔ Cost-Efficient – More affordable than QSFP-100G optical modules +
fiber, reducing overall infrastructure costs.
✔ Cisco Certified & Reliable – Fully compatible with Cisco Nexus
9000/3000 series and other Cisco switches, ensuring stable
performance.
