## Summary description

The MaxLink 25G SFP28 DAC cable is a passive direct attach copper cable designed for high-speed data transmission. With a length of 1 meter, it supports 25G Ethernet standards and features DDM (Digital Diagnostic Monitoring) for enhanced performance monitoring. Ideal for data centers and networking applications, this cable offers reliable connectivity and low latency.

## Long description

The MaxLink ML-DAC28+1 SFP28 DAC Passive 1m Black is a 1-metre passive direct attach copper cable compatible with SFP28 ports and designed for 25G Ethernet links. This MaxLink 25G SFP28 DAC cable provides low-latency, short-reach connectivity for switch-to-switch, switch-to-server and server-to-server interconnects in data center and enterprise networking environments. The cable incorporates Digital Diagnostic Monitoring (DDM) to report real-time operating parameters and supports industry-standard SFP28 form-factor electrical interfaces.
Advantages
The passive SFP28 DAC design delivers a low-cost, energy-efficient alternative to active optical modules for short-distance connections while maintaining 25G performance. Built with robust copper conductors and standardized SFP28 connectors, this cable offers stable signal integrity and low insertion loss. Integrated DDM enables monitoring of parameters such as temperature and voltage, which simplifies troubleshooting and network management. The 1 m length and compact, black jacket make routing and rack cabling straightforward in dense equipment layouts.
Suitable for
25 Gigabit Ethernet switch-to-switch links in data centers
Server to top-of-rack or leaf switch connections
High-density rack interconnects and short-reach aggregation links
Environments requiring DDM monitoring for diagnostics
Key specifications
Form factor: SFP28 direct attach copper (DAC) passive
Data rate: 25 Gbps per channel (25G Ethernet)
Length: 1 metre
Connector type: SFP28 electrical connectors on both ends
Monitoring: Digital Diagnostic Monitoring (DDM) support
Cable jacket: black, flexible copper assembly suitable for short-reach
Typical use: short-reach intra-rack and adjacent-rack connections
How to use
Install the MaxLink SFP28 DAC by inserting each SFP28 connector into the corresponding SFP28 slot until it clicks into place. Ensure both network ports are powered down or support hot-plug insertion according to the switch or server vendor guidelines. Verify that the connected devices are configured for 25G Ethernet operation and allow the link to initialize; DDM values can be checked through the device management interface for operational parameters. To disconnect, release the retention mechanism on each connector and withdraw the cable carefully to avoid stressing the ports.
Usage recommendations
Use this passive SFP28 DAC for short-distance, high-throughput links within racks or between adjacent racks. Avoid routing the cable near high-power or high-interference sources, and maintain bend radii recommended by equipment manufacturers to preserve signal integrity. For longer distances or cross-datacenter links, consider optical transceivers and fiber cabling instead of passive copper DACs.
