## Summary description

The Cisco QSFP-4SFP25G-CU3M is a 3-meter InfiniBand/fibre optic cable featuring a QSFP connector on one end and four SFP25G connectors on the other.

Its durable construction ensures reliable performance, while the black design provides a professional look. Perfect for enhancing network efficiency and reducing latency in high-demand environments.

## Long description

The Cisco QSFP-4SFP25G-CU3M is a 3 m copper direct-attach breakout cable that terminates in one QSFP connector and four SFP25G connectors. Designed for very short links inside racks and between adjacent racks, the cable provides a cost-effective wired connection option for Cisco switches and servers supporting 100G QSFP and 25G SFP ports. The cable is intended for high-density environments where consolidating a 100G port into four 25G links reduces cabling complexity and cost.
Advantages
This passive breakout cable offers a simple and reliable method to split a 100G QSFP port into four independent 25G SFP links without active electronics, lowering power consumption and complexity. Available in a 3 m length, it supports short-reach connections within and between racks, is compatible with Cisco QSFP and SFP25G ports, and provides a compact and durable black construction for professional installations.
Suitable for
Connecting a 100G QSFP port to four 25G SFP ports within the same rack
Linking adjacent racks or short data center runs (very short links)
High-density switch-to-server or switch-to-switch breakout connections
Environments where passive low-power cabling is required
