BlueOptics QSFP-4SFP25G-CU3M Compatible Cisco QSFP-4SFP25G-CU3M BlueLAN Passive 100GBASE-CR4 QSFP28 to 4x25GBASE-CR SFP28 Direct Attach Breakout Cable, 3m, AWG26

The BlueOptics QSFP-4SFP25G-CU3M is a high-performance passive direct attach breakout cable designed for 100 Gigabit Ethernet connectivity. It converts a single QSFP28 port into four independent 25 Gigabit SFP28 links, ideal for data center top-of-rack switching and high-density server connections. This cable is fully compatible with Cisco QSFP-4SFP25G-CU3M and offers a cost-effective, low-power solution for short-range interconnects up to 3 meters.

Advantages

This breakout cable simplifies cabling by replacing four separate cables with one, reducing clutter and improving airflow. It is passive, consuming less than 0.5W, and supports hot swapping for easy maintenance. The AWG26 twinax copper construction ensures reliable signal integrity with low latency.

Suitable for

• Data center top-of-rack (ToR) to server connections
