Cabo SFP28 DAC BlueOptics SFP28-DAC-0.5M-MT 0,5 m macho/macho

The BlueOptics SFP28-DAC-0.5M-MT is a 0.5 m SFP28 direct attach copper (DAC) cable with male SFP28 connectors at both ends. Designed for short-reach, high-speed links, this 0.5m cable provides a low-latency physical connection between compatible networking devices such as switches, routers and server NICs. The cable’s construction and SFP28 terminations make it suitable for use in dense rack environments and short interconnects inside data centres and server rooms.

Advantages

This SFP28 DAC cable offers native SFP28 interface compatibility for 25Gbps links and low power consumption compared with optical transceivers. The 0.5 m length reduces clutter and signal loss on short runs while maintaining predictable electrical performance. With robust male-to-male SFP28 terminations and a compact, flexible assembly, the cable enables reliable physical connections in constrained spaces.

Suitable for

• Short-distance 25Gbps connections between switches and servers
• Top-of-rack and inter-rack patching in data centres
• Direct attach links for server NICs and storage controllers
• High-density rack installations where short, fixed-length cabling is required

Key specifications

• Cable length: 0.5 m
• Connector type: SFP28 to SFP28 (male/male)
• Data rate: designed for 25 Gbps class links (SFP28)
• Cable type: direct attach copper (DAC)
• Colour: Black

How to use

Power down or follow equipment hot-swap procedures as recommended by device manufacturers before installing the SFP28 DAC cable. Align each SFP28 connector with the corresponding port and insert firmly until the latch engages. Verify link status LEDs on connected devices or check the network management interface to confirm the link has been established. For removal, release the connector latch and pull straight out to avoid damaging the port.

Recommendations

Use this 0.5 m BlueOptics SFP28 DAC cable for short, direct connections inside racks and between adjacent units. Avoid sharp bends and excessive strain on the cable; maintain the manufacturer’s minimum bend radius. Store and operate within the temperature and humidity ranges specified by your network equipment vendor, and verify compatibility with your devices’ SFP28 ports before deployment.
