Cabo DAC SFP28 BlueOptics SFP28-DAC-3M-VA 3 m macho/macho

The BlueOptics SFP28-DAC-3M-VA is a 3-meter SFP28 Direct Attach Copper (DAC) cable with male-to-male terminations designed for short-reach, high-speed interconnects. It supports SFP28 interfaces used in modern 25GbE switches, servers and network adapters, providing a cost-effective and low-latency physical connection for rack-to-rack and chassis-to-chassis links in data center and enterprise networks.

Advantages

This direct-attach copper cable delivers low electrical latency and stable signal integrity for 25 Gigabit Ethernet links, with a fixed-length design that simplifies cabling in dense rack environments. The integrated male SFP28 connectors eliminate the need for separate transceivers, reducing power consumption and total link cost. The 3 m length balances flexibility and performance for typical intra-rack and short inter-rack deployments.

Suitable for

• 25GbE server-to-switch connections
• Switch-to-switch links within the same rack or adjacent racks
• High-performance computing clusters requiring short, low-latency links
• Data center top-of-rack and aggregation layer cabling

Key specifications

• Connector type: SFP28 male to SFP28 male
• Cable type: Direct Attach Copper (DAC)
• Length: 3 meters
• Supported data rate: 25 Gigabit Ethernet
• Typical use: short-reach, low-latency interconnects
• Compatibility: SFP28 ports on switches, NICs and routers that accept passive DAC

How to use

Insert each SFP28 connector into the corresponding SFP28 port on your networking devices until the connector latches. Ensure both devices are powered and configured for 25GbE operation. Verify link status through device LEDs or management interfaces and confirm negotiated speed and duplex settings. For best performance, avoid sharp bends and excessive strain on the cable and keep the cable routing clear of sources of electromagnetic interference.

Recommendations

Use this 3 m SFP28 DAC cable for short-distance, high-bandwidth connections where passive copper is supported by your equipment. Check device compatibility lists before deployment and maintain manufacturer-recommended bend radius and environmental limits to preserve signal quality and connector life.
