CBO DAC-kabel QSFP 0,5 m – Dell-compatibel (470-13550) BlueLAN

CBO Cable DAC QSFP 0.5 m — Dell compatible (470-13550) BlueLAN is a 0.5-metre Direct Attach Copper (DAC) cable designed for short-reach, high-bandwidth connections between QSFP ports in switches, servers and storage systems. The passive copper assembly delivers a straightforward plug-and-play connection for Dell-compatible infrastructure, offering low latency and consistent signal integrity across rack-to-rack or within-rack links in data centre environments.

Advantages

The DAC QSFP cable provides a cost-effective alternative to optical transceivers for short-distance links, with reduced power consumption because it is passive and does not require additional transceiver modules. Its half-metre length minimises signal attenuation while keeping cable management tidy in dense rack deployments. Compatibility with standard QSFP interfaces ensures simple installation and immediate operation without extra configuration.

Suitable for

• Short-reach connections between QSFP ports in top-of-rack and end-of-row switches
• Server-to-switch and switch-to-storage interconnects within the same rack
• High-bandwidth, low-latency links in data centre and enterprise network environments

Key specifications

• Connector type: QSFP to QSFP compatible with Dell QSFP ports
• Length: 0.5 metre
• Cable type: Passive copper direct attach
• Typical application: Short-range, high-speed link for data centre equipment
• Physical form factor: Fixed twin-axial assembly with moulded connectors

How to use

Insert each QSFP connector into the corresponding QSFP port on the network devices until the latch engages. Ensure both devices are powered and support the QSFP passive DAC connection type. No additional configuration or external power is required; the link should be recognised by the network devices and bring up the interface according to their standard port management procedures. Route the cable to avoid tight bends and secure it to maintain proper airflow and cable organisation within the rack.

Recommendations

Use this 0.5 m passive DAC for short, direct connections where low latency and minimal power draw are priorities. Avoid using the cable beyond recommended bend radii or in environments with excessive vibration or electromagnetic interference. For longer distances or environments requiring optical isolation, consider optical transceivers and fibre cabling instead.
