## Summary description

Passive DAC cable CBO QSFP-4SFP+ 1 m provides a direct-attach connection from one QSFP port to four SFP+ ports. Designed for short-reach interconnects in data centers and server racks, it offers a compact, low-latency solution without optics or additional power. Suitable for switch-to-switch or switch-to-server links where 1 m length and passive QSFP-to-SFP+ breakout are required.

## Long description

Passive DAC cable CBO QSFP-4SFP+ 1 m is a direct-attach copper assembly that breaks out one QSFP port to four independent SFP+ ports over a 1 metre fixed length. It is intended for short-reach interconnects in data centres and server racks where a compact, low-latency, and cost-effective copper connection is required. The cable operates without transceivers or separate power and provides a stable electrical interface between QSFP-enabled switches or modules and SFP+-based devices.
Advantages
This QSFP-to-4×SFP+ passive DAC offers reduced latency and deterministic performance compared with fibre solutions that require optical transceivers. The one-metre length minimises clutter in high-density rack environments and simplifies cable management for top-of-rack and end-of-row deployments. As a passive direct-attach solution it eliminates the need for separate optics, lowering both initial hardware cost and ongoing spare-part complexity while providing reliable, low-power interconnects for short-distance links.
Suitable for
 Switch-to-switch interconnects inside racks
 Switch-to-server connections where QSFP breakout is required
 High-density top-of-rack deployments
 Short-reach links in data centre aggregation and spine-leaf topologies
Key specifications
 Connector type: QSFP (one end) to 4 × SFP+ (other end)
 Length: 1 metre fixed
 Media: Passive copper direct-attach assembly
 Use case: Short-reach electrical breakout for 10 G/40 G class ports
 Form factor: Breakout cable with integrated connectors, compact profile for high-density racks
How to use
Install the QSFP end into the QSFP port of the source switch or transceiver slot and plug the four SFP+ connectors into the destination SFP+ ports. Ensure both ends are fully seated and the host devices are powered off or follow live-insertion guidelines of the equipment manufacturer if supported. Verify link lights and device port status in the switch or server management interface after insertion. No additional configuration is required by the cable itself; port configuration should match the intended link speed and breakout mode as supported by the networking hardware.
Usage recommendations
Use this passive DAC for short-distance connections within the same rack or adjacent racks; avoid runs beyond the specified 1 m length. Confirm that your network equipment supports passive QSFP-to-SFP+ breakout and that firmware settings allow the intended port breakout mode. Keep the cable free from sharp bends and secure it to avoid strain on the connectors.
