Cavo DAC CBO SFP28-DAC-2M 2 m — cavo in rame direct attach SFP28, compatibile con Mikrotik

CBO SFP28-DAC-2M is a 2-metre direct-attach copper (DAC) cable designed for SFP28 ports and compatible with Mikrotik networking equipment. It delivers a fixed 25Gb/s electrical connection for short-reach interconnects inside racks and between adjacent devices. The passive copper assembly eliminates the need for separate transceivers, offering a compact, low-latency link that is suitable where fiber optics are not required.

Advantages

The DAC cable provides a reliable 25Gb/s link with minimal latency and low power consumption compared with active modules and optical transceivers. Its fixed length and integrated connectors simplify rack cabling and reduce the number of components to manage. Being passive over a short 2 m span, it offers predictable performance and straightforward compatibility with compatible SFP28 ports on Mikrotik devices.

Suitable for

• Switch-to-switch connections in the same rack or adjacent racks
• Switch-to-server or switch-to-storage links inside data center cabinets
• Short-range uplinks where fiber transceivers are unnecessary
• High-density networking deployments requiring low-latency interconnects

Key specifications

• Interface: SFP28 electrical direct-attach copper
• Data rate: 25 Gb/s full-duplex
• Length: 2 metres
• Connector type: Integrated SFP28 connectors on both ends
• Cable type: Passive copper twinax assembly for short-range links
• Typical use: Short-reach rack and cabinet interconnects

How to use

Insert each integrated SFP28 connector into the SFP28 port of the devices you want to interconnect, ensuring the cable latches are engaged. Verify link status on both devices and configure network settings as required for a 25Gb/s interface. For best results, route the cable to avoid tight bends and excessive mechanical stress; the assembly is intended for short, direct connections within racks or between adjacent cabinets.

Recommendations

Use this DAC cable for short, fixed-length connections where 25Gb/s electrical links are supported by the equipment. Avoid sharp bends and do not exceed the recommended ambient temperature and mechanical stress limits. When replacing active optical modules or longer fiber links, confirm that the connected devices accept passive DAC assemblies and that firmware or vendor compatibility is met.
