## Summary description

Passive direct-attach breakout cable BlueOptics QSFP-4SFP10G-CU5M provides a 40GBASE-CR4 QSFP-to-4×SFP+ connection over a 5‑meter copper assembly. The cable splits a single QSFP port into four 10 Gbps SFP+ links for server, switch or storage interconnects in data centers, top-of-rack deployments, and aggregation use cases. Passive copper design requires no external power or transceivers.

## Long description

Passive Direct Attach Breakout Cable BlueOptics QSFP-4SFP10G-CU5M 40GBASE-CR4 5 m (blue) is a copper assembly that delivers a 40GBASE-CR4 QSFP-to-4×SFP+ connection across a 5‑meter link. Designed for direct, short-reach connectivity in data center environments, this passive breakout cable splits a single 40 Gbps QSFP port into four independent 10 Gbps SFP+ channels without requiring external power or active transceivers. The cable's compact construction and color-coded jacket simplify identification and routing in rack and tray installations.
Advantages
This passive breakout cable provides a cost-effective and low-latency method to connect QSFP ports to multiple SFP+ devices. Because it is a passive copper assembly, it requires no additional power or optical modules, reducing component count and heat output. The 5 m length balances reach and manageability for top-of-rack and short aggregation connections, while the standardized QSFP-to-SFP+ pinout ensures compatibility with equipment supporting 40GBASE-CR4 to 4×10G breakout configurations.
Suitable for
 Short-reach interconnects between servers, switches and storage in data centers
 Top-of-rack deployments where a QSFP port is split into four 10 Gbps links
 Aggregation and leaf-spine architectures requiring multiple 10 Gbps links
 Patch panels and cable management runs within the same rack or adjacent racks
Key specifications
 Form factor: QSFP to 4 × SFP+
 Standard: 40GBASE-CR4 breakout to 4 × 10GBASE-CR
 Cable type: Passive copper direct attach
 Length: 5 meters
 Color: Blue jacket for easy identification
 Data rate: 40 Gbps aggregated (4 × 10 Gbps channels)
 Connector interfaces: QSFP at one end, four SFP+ plugs at the other
How to use
Insert the QSFP end into a compatible 40 Gbps QSFP port on a switch or network device and plug each SFP+ connector into the corresponding 10 Gbps SFP+ ports on target servers, switches or storage units. Ensure devices support passive copper breakout operation and that port configurations (including lane mapping and speed settings) are set according to vendor guidance. Route the cable to avoid excessive bending and secure it with cable management to maintain airflow and prevent strain on connectors.
Usage recommendations
Verify compatibility with switch firmware and port breakout capabilities before deployment. Use this passive cable for short-reach connections up to 5 m; for longer runs, consider active copper or optical transceivers. Maintain proper bend radius, avoid cable ties that compress the jacket, and label both ends for easier maintenance and troubleshooting.
