Extend Your 100G Connectivity with Confidence
The Cisco QSFP-100G-CU5M is a factory-sealed 5-meter passive DAC Twinax cable designed to deliver 100GBASE-CR4 performance between QSFP28 ports. Ideal for switch-to-switch or switch-to-server links across adjacent racks, this high-quality copper cable delivers ultra-low latency with minimal power consumption.
As part of Cisco’s official 100G DAC portfolio, the CU5M ensures full compatibility, exceptional signal integrity, and long-term reliability in dense rack environments.
Choosing the Right DAC Cable Length
- 1M & 2M: Best for direct Top-of-Rack switch-to-server links or within the same rack.
