SFP28 DAC Cable BlueOptics SFP28-DAC-3M-F5 3m Male/Male

The BlueOptics SFP28-DAC-3M-F5 is a 3 m SFP28 DAC cable designed to provide a direct, low-latency connection between SFP28 ports. With male SFP28 connectors on both ends and an overall cable length of 3 m, this cable is intended for short-reach, high-speed links such as switch-to-switch or switch-to-server connections in rack and data centre environments. The cable is compact and lightweight while offering the electrical performance expected for 25GbE and other SFP28-compatible applications.

Advantages

This SFP28 DAC cable offers a fixed-length, plug-and-play solution that eliminates the need for separate transceivers. Its direct-attach design reduces power consumption compared with active optical modules and simplifies installation in dense rack configurations. The male-to-male SFP28 connectors ensure physical compatibility with standard SFP28 ports, while the 3 m length provides flexibility for short interconnects without excess cable slack.

Suitable for

• Short-reach 25GbE connections between switches
• Direct links from switches to servers with SFP28 ports
• Patch connections inside network racks and cabinets
• High-density top-of-rack deployments requiring compact cabling

Key specifications

• Cable length: 3 m
• Connector type (each end): SFP28 male
• Intended interface: SFP28 (25GbE compatible)
• Product colour: Black
• Weight: 0.08 kg

How to use

Insert each male SFP28 connector into the corresponding SFP28 port on your network devices until the connector latches. Ensure devices are powered and that firmware or port settings support the SFP28 link speed required. For initial setup, verify link status LEDs and check device interfaces for the negotiated speed and duplex. Disconnect by depressing the connector latch and gently pulling the module from the port.

Recommendations

Use the cable for short-distance, high-speed interconnects inside racks or between adjacent racks. Avoid sharp bends and maintain minimum bend radius specified by your equipment manufacturer. For optimal performance, keep cable length appropriate for the link and use SFP28-compatible ports; do not exceed the intended short-reach application environment.
