DAC-kabel CBO QSFP28-DAC-5M 5 m — QSFP28 directe aansluiting koperkabel, 5 meter lengte, compatibel met Coriant

CBO QSFP28-DAC-5M is a 5-meter direct-attach copper (DAC) cable designed for QSFP28 ports and compatible with Coriant equipment. It delivers a short-reach, low-latency physical link for 100GbE and other QSFP28 applications, suitable for interconnects inside racks or between adjacent racks in high-density data center environments. The cable is intended for scenarios where a reliable, low-cost copper connection is preferred over optical transceivers for distances up to five meters.

Advantages

The QSFP28-DAC-5M provides a low-latency, energy-efficient connection that reduces cost and complexity compared with transceiver-plus-fibre solutions for short distances. Its 5 m length supports flexible rack-to-rack and within-rack cabling while maintaining signal integrity for 100GbE links. Compatibility with Coriant QSFP28 ports ensures plug-and-play installation in supported systems and minimizes configuration overhead.

Suitable for

• Rack-to-rack 100GbE connections in data centres
• Within-rack high-density switch-to-switch or switch-to-server interconnects
• Short-reach QSFP28 links where low latency and cost-effectiveness are required
• Environments that prefer copper direct-attach cabling over optical transceivers for up to 5 m

Key specifications

• Connector type: QSFP28 direct-attach copper
• Length: 5 metres
• Application: 100 Gigabit Ethernet and other QSFP28-compliant links
• Reach: short-reach copper suitable for up to 5 m
• Latency: low-latency physical interconnect for high-performance switching
• Form factor: passive/active DAC depending on host compatibility

How to use

Install the QSFP28-DAC-5M by inserting each QSFP28 plug into the corresponding QSFP28 ports on network switches, routers or servers, ensuring the connectors are aligned and fully seated. Verify port compatibility with the host equipment and confirm link status through the device management interface. For proper handling, avoid sharp bends and excessive mechanical stress on the cable; route the cable following standard data centre cable-management practices to prevent kinks and to maintain airflow.

Recommendations

Use this direct-attach copper cable for short-distance 100GbE connections where cost, power consumption and latency are priorities. Confirm that the network equipment firmware and port compatibility match the cable type (passive or active DAC) before deployment, and maintain cable bend radius and environmental conditions consistent with standard data centre guidelines.
