BlueOptics SFP28 to SFP28 Direct Attach Cable 25GBASE-CR, 1 m, AWG30 (compatible with Infortrend 9370CM25GCAB3-0030)

BlueOptics SFP28 to SFP28 Direct Attach Cable 25GBASE-CR, 1 m, AWG30 is a passive copper twinax assembly designed to provide a point-to-point 25 Gigabit Ethernet connection between two SFP28 ports. The 1-metre length and AWG30 conductor gauge make this cable suitable for short-distance interconnects inside racks or between adjacent racks, delivering low-latency and low-power connectivity for servers, switches and storage systems. The cable supports the 25GBASE-CR electrical specification and is intended for environments that require a simple, reliable copper link for 25 GbE links.

Advantages

This direct attach SFP28 copper cable offers a low-latency connection with minimal power consumption compared with active optical alternatives. Its fixed 1 m length and AWG30 construction ensure predictable signal performance for short-reach links and reduce the need for additional transceivers and fiber patching. The SFP28 to SFP28 form factor provides plug-and-play compatibility with equipment that accepts passive SFP28 DACs, simplifying installation and reducing materials and space requirements in dense rack deployments.

Suitable for

• Short-distance 25 GbE links between servers and Top-of-Rack or Leaf switches
• Intra-rack connections in data center cabinets
• Interconnects between adjacent racks where 1 m cable length is appropriate
• Storage systems and SAN fabrics using SFP28 ports

Key specifications

• Interface: SFP28 to SFP28 (passive direct attach)
• Data rate: 25 Gigabit Ethernet (25GBASE-CR)
• Length: 1 metre
• Conductor gauge: AWG30 twinax
• Cable type: Passive twinax copper DAC
• Typical use: Short-reach, rack or adjacent-rack interconnects

How to use

Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on your devices until the latch engages. Confirm both ends are seated and secured; no additional configuration is required on most switches, servers or storage devices that support passive DACs. Verify link status through device LEDs or management interfaces and ensure network settings match the 25 GbE link speed. For best results, avoid sharp bends and maintain recommended bend radius to preserve signal integrity.

Usage recommendations

Use this 1 m passive SFP28 DAC for short, direct server-to-switch and switch-to-switch connections where a low-cost, low-power 25 GbE solution is needed. Ensure device compatibility with passive SFP28 copper assemblies and route the cable to prevent mechanical stress; replace the cable if the connector latches or conductors show visible damage.
