DAC cable CBO QSFP28 100G CAB-Q-Q-100G-1.5 1.5 m blue

Direct Attach Copper (DAC) cable CBO QSFP28 100G CAB-Q-Q-100G-1.5 1.5 m blue is a 1.5 metre passive twin-ax cable designed to deliver 100 Gigabit Ethernet connectivity over short distances. Engineered for within-rack and adjacent-rack connections, this QSFP28 cable provides a low-latency, low-power physical link suitable for high-density switch-to-switch and server-to-switch interconnects in data center and enterprise environments.

Advantages

This DAC QSFP28 cable offers a compact and cost-effective alternative to active optical modules for short-reach links, eliminating the need for separate transceivers. Passive construction reduces power consumption and simplifies installation while maintaining reliable 100G throughput. The cable’s QSFP28 connectors support high-density port layouts and enable straightforward hot-plug deployment without additional configuration.

Suitable for

• Within-rack switch-to-switch connections
• Server-to-switch links in short-reach topologies
• Adjacent-rack high-speed interconnects
• High-density data center patching and aggregation

Key specifications

• Connector type: QSFP28 to QSFP28
• Data rate: 100 Gbps
• Cable length: 1.5 metres
• Cable type: Passive twin-ax copper
• Color: Blue
• Application: Short-reach, within-rack and adjacent-rack interconnects

How to use

Insert each QSFP28 connector firmly into the corresponding port on the network devices until the latch engages. Verify link status through the devices’ management interfaces or LED indicators. For best performance, route the cable to avoid sharp bends and mechanical strain; maintain bend radius consistent with typical twin-ax copper specifications. No additional configuration or transceivers are required when replacing or installing this passive DAC cable in supported ports.

Recommendations

Choose this 1.5 m QSFP28 DAC cable for short-distance 100G links inside racks or between adjacent racks. Ensure compatible QSFP28 ports and check device documentation for any vendor compatibility notes. Avoid routing near high-power electrical sources and secure both ends to prevent accidental disconnection.
