SFP28 DAC Cable BlueOptics SFP28-DAC-5M-RW 5m Male/Male

The BlueOptics SFP28-DAC-5M-RW is a 5-meter SFP28 Direct Attach Copper (DAC) cable with male SFP28 connectors on both ends, designed for reliable high-speed data links in short-reach environments. Intended for use with 25GbE and compatible SFP28 ports, the cable provides a low-latency, power-efficient physical connection for networking equipment in racks, top-of-rack switches and server interconnects.

Advantages

This SFP28 DAC cable offers predictable performance for short-distance connections with minimal signal loss and low latency. The direct-attach copper construction eliminates the need for transceivers, reducing power consumption and overall system cost. With a 5 m length and standardized SFP28 male interfaces on both ends, the cable is straightforward to install and maintain in dense cabling environments.

Suitable for

• Short-reach links between switches and servers within racks
• Top-of-rack to aggregation switch connections in data centres
• High-density network deployments requiring 25GbE connectivity
• Environments where low latency and reduced power draw are important

Key specifications

• Cable length: 5 m
• Connector type: SFP28 male to SFP28 male
• Intended data rate: compatible with 25 Gigabit Ethernet (SFP28)
• Construction: direct attach copper (DAC)
• Colour: Black
• Weight: approximately 0.08 kg

How to use

Ensure both network devices support SFP28 direct-attach copper connections and are powered down or in a safe state before installation if required by your maintenance procedures. Align the SFP28 male connector with the SFP28 port and insert until the latch engages; repeat for the other end. After installation, verify link status on connected equipment and confirm the expected data rate and link integrity via switch or server management interfaces.

Recommendations

Use the cable for short, intra-rack or adjacent-rack connections up to 5 meters. Avoid tight bends and excessive pulling force; maintain manufacturer-recommended bend radius for copper cables. Keep connectors free of dust and contaminants and verify compatibility with vendor equipment to ensure proper link negotiation and performance.
