Cavo DAC QSFP28 BlueOptics QSFP28-DAC-1M-IT 1m connettore/connettore

The BlueOptics QSFP28-DAC-1M-IT is a 1-meter passive direct attach copper (DAC) cable with QSFP28 male connectors on both ends, designed for 100 Gigabit Ethernet interconnects in data center and high-performance networking environments. This compact cable provides a low-latency, short-reach solution for connecting switches, servers, and network interface cards where cost-effective, high-throughput links are required.

Advantages

The cable delivers reliable high-speed data transmission with minimal power consumption due to its passive design. Its QSFP28 form factor supports 100 Gbps links while maintaining protocol compatibility with QSFP28 ports, enabling straightforward plug-and-play deployment. At 1 meter length the cable reduces signal attenuation and provides robust mechanical stability for rack-mounted equipment. The blue jacket allows quick visual identification within cable bundles.

Suitable for

• Short-reach connections between top-of-rack switches and adjacent aggregation switches
• Direct links between servers and network interface cards supporting QSFP28
• High-density data center deployments requiring compact, low-latency interconnects
• Test environments and lab setups for 100 Gigabit Ethernet

How to use

Insert each QSFP28 connector into the corresponding QSFP28 port on networking equipment until the latch engages. Ensure both devices are powered and compatible with passive DAC connections for 100 Gbps operation. For best performance, avoid sharp bends and excessive strain on the cable; maintain the specified minimum bend radius and route the cable to prevent interference from heavy electrical sources. Confirm link status through the equipment’s management interface after installation.

Recommendations

Use this passive QSFP28 DAC cable for short-distance, high-throughput links inside racks or between adjacent racks. Avoid using beyond intended short-reach distances and do not expose the cable to high temperatures or solvents. Periodically inspect connectors for dust or debris and clean with appropriate fiber-optic-safe tools if needed to maintain reliable connections.
