## Summary description

CBO DAC cable BN-QS-QS-CBL-05M is a 5-meter QSFP direct-attach copper (DAC) cable for short-range high-speed connections between QSFP ports. It provides a cost-effective, low-latency link for switches, routers and servers that support QSFP interfaces. Intended for data center rack-to-rack or intra-rack connectivity where a fixed-length copper cable is suitable.

## Long description

BlueOptics DAC cable BN-QS-QS-CBL-05M is a 5-metre QSFP direct-attach copper (DAC) cable designed for short-range, high-speed links between QSFP ports. The fixed-length copper assembly provides a low-latency physical connection suitable for data centre rack-to-rack or intra-rack connectivity. This cable is intended for use where a cost-effective, power-efficient alternative to active optical modules is required and where devices provide QSFP ports that accept direct-attach copper interconnects.
Advantages
The DAC cable offers low latency and stable electrical performance over its 5 m length, eliminating the need for transceivers and reducing both power consumption and component count in a rack. A fixed, factory-terminated QSFP-to-QSFP copper assembly simplifies installation and reduces points of failure compared with discrete module and fibre assemblies. Compatibility with standard QSFP interfaces ensures plug-and-play operation in equipment that supports QSFP direct-attach copper cables.
Suitable for
Short-range links between switches and top-of-rack or end-of-row switches
Server-to-switch connections within the same rack or adjacent racks
High-density data centre patching where low power and low cost are priorities
Environments requiring low-latency electrical connections for storage and compute clusters
Key specifications
Cable type: QSFP direct-attach copper (DAC)
Length: 5 metres
Connector format: QSFP-to-QSFP fixed assembly
Application: Short-range, high-speed interconnects in data centres
Performance: Low-latency electrical link suitable for high-throughput environments
Form factor: Fixed, factory-terminated copper cable for plug-and-play use
How to use
Insert each QSFP connector into the corresponding QSFP port on the devices to be linked, ensuring that the retainers click into place. No additional drivers or power sources are required beyond the host devices. Observe standard ESD precautions when handling the cable and avoid tight bends or kinks in the cable run; maintain the manufacturer’s minimum bend radius to preserve signal integrity. For optimal results, verify that connected devices support QSFP direct-attach copper cables and configure link settings on the switches or servers as required by the host equipment.
Usage recommendations
Use this 5 m DAC cable for short, fixed-length connections within racks or between adjacent racks. Avoid running the cable near strong electromagnetic sources, and replace the cable if connector damage or intermittent link issues are observed. For longer distances or where optical isolation is required, consider using active optical modules or fibre-optic assemblies instead.
