## Summary description

CBO QTAPCABLE-0.5M is a 0.5 m QSFP direct attach copper (DAC) cable for short-range high-speed connections between network devices with QSFP ports. Designed for reliable, low-latency links in switches, routers and servers, it offers a fixed-length passive copper connection ideal for rack-to-rack or intra-rack installations, reducing transceiver cost and power consumption.

## Long description

CBO QTAPCABLE-0.5M is a 0.5 m QSFP direct attach copper (DAC) cable designed for short-range high-speed interconnects between network devices equipped with QSFP ports. The fixed-length passive copper assembly provides a low-latency, energy-efficient connection for rack-to-rack or intra-rack links, enabling cost-effective connectivity without the need for separate optical transceivers. The cable is intended for use in environments where reliable, high-throughput connections are required between switches, routers and servers.
Advantages
The QSFP direct attach copper design delivers low latency and stable signal integrity over short distances, with reduced power consumption compared to active optical solutions. A 0.5 m fixed length simplifies cable management in densely populated racks and minimizes signal attenuation typical of longer copper links. Passive copper construction eliminates the need for separate transceiver modules, helping to lower total equipment cost while maintaining high data throughput and reliable connections.
Suitable for
 Short-range 40G/100G (or compatible QSFP speeds) connections between switches in the same rack
 Direct server-to-switch links in data center racks
 High-density network deployments requiring compact cable routing
 Environments where reduced power consumption and cost per link are priorities
Key specifications
 Connector type: QSFP to QSFP direct attach copper
 Length: 0.5 m (fixed)
 Cable type: Passive copper assembly
 Application: Short-reach high-speed interconnects for switches, routers and servers
 Latency: Low-latency physical link suitable for high-throughput traffic
 Power: Passive operation with no additional power draw for transceivers
How to use
Insert each QSFP connector into the corresponding QSFP port on the network devices until the connector latches. Ensure both ports are compatible with QSFP direct attach copper cables and that devices are powered off or restarted according to the vendor's hot-plug guidance if required. After physical insertion, verify link status in the device management interface and confirm negotiated speed and operation. Use appropriate bend radius practices and secure the cable to avoid mechanical strain on ports.
Usage recommendations
For optimal performance, use the cable for short intra-rack or adjacent-rack connections and avoid routing through tight bends or cable bundles that exceed recommended bend radius. Verify device compatibility with QSFP passive DAC assemblies and consult switch or server documentation for any firmware or configuration requirements related to direct attach copper links.
