Cabo DAC SFP28 BlueOptics SFP28-DAC-2M-UQ 2 m macho/macho

The BlueOptics SFP28-DAC-2M-UQ is a 2-meter SFP28 Direct Attach Copper (DAC) cable with male SFP28 connectors on both ends, designed for reliable short-reach, high-speed data links. Intended for use in data centers and network closets, this cable supports direct connections between SFP28 ports on switches, routers and servers where low latency and predictable performance are required.

Advantages

This passive DAC cable offers a cost-efficient alternative to optical transceivers for short distances, reducing power consumption and eliminating the need for separate transceivers and patch cords. The fixed 2 m length simplifies cable management in rack environments and helps maintain signal integrity over the specified short reach. The SFP28 form factor ensures compatibility with equipment that accepts SFP28 Direct Attach Copper modules.

Suitable for

• Direct server-to-switch connections within racks and between adjacent racks
• High-speed 25GbE links in data center topologies
• Short-distance interconnects in network closets and aggregation points

Key specifications

• Cable length: 2 m
• Connector type: SFP28 to SFP28, male/male
• Cable medium: Direct attach copper (DAC)
• Intended use: Short-reach, high-speed data transmission
• Colour: Black

How to use

Insert each SFP28 connector into the corresponding SFP28 port on the networking devices until the connector latches. Ensure both devices are powered and configured for compatible link settings (for example, 25GbE) before enabling traffic. For best results, route the cable to avoid sharp bends and mechanical stress and verify the link status through the device management interface after installation.

Recommendations

Use this 2 m SFP28 DAC for short, fixed connections inside racks or between immediately adjacent racks. Avoid exceeding the recommended bend radius and maintain a tidy cable layout to preserve signal quality. If longer runs or optical isolation are required, consider using optical transceivers and fiber cabling instead.
