Network Cable MaxLink ML-DAC28+2 SFP28 DAC Passive 2m Black

The MaxLink ML-DAC28+2 SFP28 DAC Passive 2m Black is a passive direct attach copper cable designed for 25G Ethernet interconnects. At 2 meters length it delivers a stable physical connection between SFP28 ports on switches, servers and NICs, offering low latency and minimal power overhead. The cable includes Digital Diagnostic Monitoring (DDM) support to report link status and operating parameters to connected equipment, enabling straightforward performance checks in rack environments.

Advantages

This MaxLink SFP28 DAC cable provides a compact and cost-effective solution for short-reach 25G links. Its passive design reduces power consumption compared with active optical transceivers, while the copper assembly maintains predictable latency and thermal behavior. Built for plug-and-play operation, it offers reliable electrical performance and DDM visibility without requiring additional configuration.

Suitable for

• 25G server-to-switch or switch-to-switch connections in data centers
• High-performance computing clusters and storage arrays requiring short-reach links
• Top-of-rack and middle-of-row cabling within rack deployments
• Environments prioritizing low latency and reduced power consumption

Key specifications

• Data rate: 25 Gigabit Ethernet
• Connector type: SFP28 direct attach copper
• Length: 2 meters
• Type: Passive DAC (direct attach copper)
• Monitoring: Digital Diagnostic Monitoring (DDM) support
• Color: Black

How to use

Install the cable by inserting the SFP28 connectors into compatible SFP28 ports on network equipment until they latch securely. Verify that connected devices recognize the link and report status through management interfaces or DDM readings. For reliable operation, route the cable within the rack to avoid sharp bends and mechanical stress; ensure both ends are fully seated before applying persistent traffic loads.

Usage recommendations

For optimal performance, use this 2m passive DAC for short intra-rack or adjacent-rack links where 25G bandwidth is required. Avoid exceeding the recommended bend radius, keep the cable away from heat sources, and ensure port compatibility with SFP28 passive DAC modules. Regularly monitor DDM values via your switch or server management tools to detect any degradation in link performance.
