Cavo DAC SFP28 CBO SC272701Q0.5M30 0,5 m maschio-maschio 25 Gbit/s

The SFP28 DAC cable CBO SC272701Q0.5M30 0.5 m Male-to-Male 25 Gbit/s is a direct-attach copper solution for short-reach 25 Gigabit connections. This fixed-length assembly connects SFP28 ports on switches, routers and network adapters, delivering low-latency, low-power high-speed transmission for data centre topologies such as rack-to-rack links and server uplinks. The male-to-male SFP28 form factor provides a compact, plug-and-play connection without the need for separate transceivers.

Advantages

This DAC cable offers native 25 Gbit/s performance with minimal signal processing, resulting in lower latency compared with optical transceivers. Its fixed 0.5 m length reduces clutter in dense rack environments while maintaining consistent signal integrity. Power consumption is reduced because the assembly eliminates the need for powered optical modules, and the robust SFP28 connectors ensure reliable mechanical mating for frequent hot-plug operations.

Suitable for

• Short-reach links between adjacent switches and top-of-rack devices
• Server-to-switch uplinks in data centres and server rooms
• High-density rack environments requiring low-latency connections

Key specifications

• Interface: SFP28 Male-to-Male
• Data rate: 25 Gbit/s
• Length: 0.5 m
• Medium: Direct-attach copper assembly
• Typical use: Short-reach, rack-to-rack and server uplink connections

How to use

Insert each SFP28 connector into the corresponding SFP28 port on your network devices until the latch engages. Ensure devices are powered according to vendor guidelines and confirm port negotiation at 25 Gbit/s through your switch or adapter management interface. For best results, install the cable when devices are accessible to avoid strain on connectors and maintain proper cable routing to prevent bend stress.

Recommendations

Use this 0.5 m DAC cable for short-distance interconnects within the same rack or adjacent racks. Avoid sharp bends and maintain proper airflow around equipment. Verify compatibility with your switch or adapter firmware and vendor support matrices before deployment to ensure link up at 25 Gbit/s.
