QSFP-4SFP25G-CU1M — QSFP28 100 Gbps

The Cisco QSFP-4SFP25G-CU1M is the shortest QSFP28-to-4xSFP28 breakout DAC cable in the product line, distributing 100 Gbps across four SFP28 ports at 25 Gbps each over just 1 metre of pre-terminated copper. Entirely passive with no embedded active components, it operates from 0 to 70 °C.

This 1 m length is optimal for top-of-rack deployments where the 100G switch and 25G servers are placed virtually side by side, reducing cable volume to a minimum in very dense racks. It is the most compact reference in the Cisco QSFP28 100G breakout series. Genuine Cisco hardware, manufacturer warranty.
