## Summary description

The BlueOptics SFP28-DAC-3M-CN is a 3-meter SFP28 DAC cable with male connectors on both ends. It is designed for high-speed data transmission in data centers and networking environments, ensuring reliable connectivity and performance.

## Long description

The BlueOptics SFP28-DAC-3M-CN is a 3-meter direct attach copper (DAC) cable with SFP28 male connectors on both ends, intended for short-reach 25GbE links in data centers and networking racks. Designed for use with SFP28 ports, this passive cable provides a cost-effective, low-latency connection option for switches, routers and network interface cards where a fixed, reliable copper link is required.
Advantages
This SFP28 DAC cable delivers consistent 25 Gigabit Ethernet performance over a 3 m copper assembly, offering low power consumption compared with active optical solutions. The integrated SFP28 male terminations simplify installation by plugging directly into compatible ports without the need for separate transceivers. Its passive construction reduces heat generation and often lowers total system cost for short-reach interconnects.
Suitable for
 Inter-switch connections in data centre racks
 Server to top-of-rack switch uplinks
 High-density network deployments requiring short fixed-length links
 25 Gigabit Ethernet lab and test environments
Key specifications
 Connector type: SFP28 male on both ends
 Cable length: 3 m
 Supported data rate: up to 25 Gbps per lane (25GbE)
 Media type: direct attach copper (DAC)
 Typical power: passive copper design (low power consumption)

How to use
Ensure both devices have compatible SFP28 ports and that firmware or driver support exists for DAC modules. With equipment powered down or per your organisation’s hot-plug policy, align the SFP28 connectors and insert each end into the corresponding ports until the latch engages. Verify link status via the network device management interface or indicator LEDs and configure link settings on connected devices as required for 25GbE operation.
Usage recommendations
For reliable operation, avoid sharp bends in the cable and maintain the 3 m routing free of tight bundles near hot equipment. Confirm compatibility lists for your switch or server vendor when planning large deployments and keep firmware updated to ensure optimal link negotiation and performance.
