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

The BlueOptics SFP28-DAC-5M-BL is a 5-meter SFP28 direct attach copper (DAC) cable with SFP28 male connectors on both ends. Designed for short-reach, high-speed connections, this passive twinax cable supports 25G data rates and is intended for rack-to-rack or intra-rack links in data centers and high-performance computing environments. The cable is manufactured to industry MSA guidelines and is offered in a blue housing with black and silver elements, weighing approximately 0.13 kg.

Advantages

This direct attach cable provides a cost-effective physical link for short-distance 25G interconnects with low latency and low power consumption compared to active optical alternatives. As a passive twinax solution, it requires no external power or transceivers, simplifying installation and reducing potential points of failure. The 5 m length is suitable for connections across adjacent racks or within the same rack, offering predictable electrical performance for supported network equipment.

Suitable for

• Short-reach 25G Ethernet connections between switches
• Server-to-switch links in data centers
• Storage system interconnects supporting 25G protocols
• High-performance computing clusters requiring low-latency links

How to use

Install the SFP28-DAC-5M-BL by inserting each SFP28 connector into the corresponding SFP28 port on your network devices until the latch engages. Ensure both devices officially support passive SFP28 DAC connections and the intended 25G protocol (for example 25GBase-CR). Route the cable to avoid tight bends and mechanical strain; maintain the specified bend radius for twinax copper to preserve signal integrity. No additional configuration is required at the physical layer beyond verifying link status in device management interfaces.

Recommendations

Verify compatibility with the switch, router or storage vendor before deployment, and test the link in your environment to confirm expected throughput and stability. For optimal longevity, avoid repeated extreme flexing and keep the cable free from sharp edges or crushing forces.
