## Summary description

Direct Attach Copper (DAC) cable CBO BN-QS-QS-CBL-05M-IB is a 0.5 metre QSFP-to-QSFP interconnect designed for short-range high-speed links between compatible QSFP ports. The passive copper assembly provides low-latency, energy-efficient connectivity for switches, routers and servers in data centres and telecom racks. Suitable for 40/56/100Gbps class QSFP interfaces where supported by equipment.

## Long description

CBO DAC Cable BN-QS-QS-CBL-05M-IB 0.5m QSFP to QSFP Direct Attach Copper is a 0.5 metre passive copper interconnect designed to link compatible QSFP ports for short-range, high-speed connections. The assembly supports typical QSFP class data rates and is intended for use where direct attach copper reduces latency and power consumption compared with optical transceivers. It is suitable for installation inside server racks and telecom cabinets to connect switches, routers and high-performance network adapters.
Advantages
The direct attach copper construction provides a low-latency physical layer connection with reduced power draw compared with optical modules that require transceivers. The 0.5 m length minimises signal degradation for short-reach links while preserving high throughput. Its QSFP-to-QSFP form factor ensures mechanical compatibility with devices that implement QSFP ports and simplifies rack-level cabling. The passive design eliminates the need for external power or configuration at the cable level.
Suitable for
 Short-range interconnects between QSFP-enabled switches and routers
 Direct connections between servers and network adapters in the same rack
 High-density patching in data centre top-of-rack or middle-of-row configurations
 Temporary or permanent links where cost-effective, low-latency copper is preferred
Key specifications
 Connector type: QSFP to QSFP
 Cable type: Direct attach copper (passive)
 Length: 0.5 metre
 Supported link classes: QSFP class high-speed interfaces (e.g., 40/56/100 Gbps where equipment supports DAC)
 Latency: minimal propagation delay characteristic of copper direct attach links
 Typical use environment: data centre racks and telecom cabinets
How to use
Install the cable by firmly inserting each QSFP connector into the corresponding QSFP port on the devices to be connected. Ensure equipment is powered down or that hot-plug procedures recommended by the device manufacturer are followed when available. Verify that both endpoints support passive DAC connections and match the required QSFP data rate. After connection, monitor link status indicators on the network equipment to confirm successful link establishment.
Usage recommendations
 Use this 0.5 m DAC for short, rack-level connections to minimise latency and power use. Avoid sharp bends and excessive tensile stress on the cable; maintain the manufacturer’s minimum bend radius. Confirm equipment compatibility with passive QSFP-to-QSFP copper assemblies and ensure firmware and port settings on switches or servers match the intended link speed and mode.
