Cavo SFP28 DAC BlueOptics SFP28-DAC-0.5M-UQ 0,5 m connettore-connettore

The BlueOptics SFP28-DAC-0.5M-UQ is a 0.5 meter direct attach copper (DAC) cable with SFP28 male connectors on both ends, engineered for 25 Gigabit Ethernet links. Its short length and fixed copper construction reduce power consumption compared with active optical alternatives while delivering low latency and high signal integrity between compatible switches, routers and servers in data center and enterprise rack environments.

Advantages

This SFP28 DAC cable provides a compact, low-cost physical connection for high-speed 25GbE links. The passive copper design offers stable electrical performance over short distances, minimal insertion loss and negligible extra latency. The dual SFP28 male interfaces ensure broad interoperability with devices that accept SFP28 direct attach modules, and the compact 0.5 m length helps maintain tidy cable runs inside racks.

Suitable for

• Short-reach connections between top-of-rack switches and servers
• Inter-switch links within the same rack or adjacent racks
• Direct server-to-switch connections in data centers
• High-density rack installations requiring low-latency links

Key specifications

• Length: 0.5 meter
• Connector type: SFP28 male to SFP28 male
• Data rate: Designed for 25 Gigabit Ethernet
• Cable type: Direct attach copper (passive DAC)
• Weight: 0.08 kg
• Color: Black outer jacket

How to use

Ensure both devices support SFP28 direct attach copper modules before installation. Power down equipment if recommended by the device manufacturer, align the SFP28 connectors with the host ports and insert until the latch engages. Verify link status through the host interfaces and network management tools. For removal, release the connector latch and pull the module straight out to avoid stressing the cable ends or device ports.

Recommendations

Use this 0.5 m DAC cable for short-distance, high-throughput links inside racks or between adjacent racks. Avoid sharp bending at the connector boot, maintain recommended bend radius for copper twinax cables, and avoid routing near sources of strong EMI. Verify compatibility with your networking equipment's supported transceiver and cable types before deployment.
