CBO QSFP28 470-ABYE-BL BlueOptics 0.5m 100Gbit/s male-to-male copper cable

The CBO QSFP28 470-ABYE-BL BlueOptics 0.5m 100Gbit/s male-to-male copper cable is a direct-attach copper (DAC) assembly with QSFP28 connectors engineered for short-reach, high-speed interconnects. At 0.5 m length and supporting a 100 Gbit/s data rate, this male-to-male cable connects compatible QSFP28 ports on switches, routers and servers without the need for separate optical transceivers, making it suitable for dense rack and data center top-of-rack connections.

Advantages

This BlueOptics QSFP28 copper cable delivers low-latency, high-throughput connectivity with reduced power consumption compared with optical solutions that require active transceivers. Its fixed 0.5 m length minimizes signal loss for short-range links and simplifies cable management in crowded racks. The male-to-male QSFP28 connectors provide a plug-and-play connection for equipment supporting QSFP28 ports, offering cost-effective and reliable performance for high-density environments.

Suitable for

• Direct interconnection of QSFP28 ports on network switches and routers
• Server-to-switch connections in rack and data center deployments
• Short-reach 100G aggregation links and top-of-rack uplinks
• High-density environments where compact, low-power cabling is required

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Length: 0.5 m
• Nominal data rate: 100 Gbit/s
• Cable type: passive direct-attach copper (DAC)
• Typical use: short-reach, rack-level interconnects

How to use

Ensure both devices have compatible QSFP28 ports and are powered down or set to a state that allows hot-plugging according to the equipment manufacturer’s guidelines. Align the QSFP28 connectors with the ports and insert until the latch engages; verify link status through the host device indicators or management interface. When removing, release the connector latch before pulling to avoid connector or port damage. No additional transceivers, modules or configuration should be required beyond confirming link settings on the connected devices.

Recommendations

Use this 0.5 m DAC cable for short, direct links inside racks or between adjacent racks. Avoid sharp bends or kinks, maintain recommended bend radius, and keep the cable free from mechanical strain. Verify compatibility lists from network equipment manufacturers to ensure full interoperability with QSFP28 ports.
