Extralink SFP28 DAC kabel SFP28 25Gbps 3m samec/samec

Extralink SFP28 DAC is a direct attach copper cable designed for short-range high-speed connections. This SFP28 cable supports 25Gbps data transfer and comes in a 3m length, offering a reliable and low-latency connection between compatible network devices with SFP28 ports.

Advantages

The Extralink SFP28 DAC provides a cost-effective and power-efficient link for server-to-switch and switch-to-switch connections. Its fixed copper assembly eliminates the need for optical transceivers and fibre cabling, simplifying installations and reducing component count. The cable’s 3m length suits typical rack-to-rack or chassis-to-chassis deployments while maintaining 25Gbps performance and low latency.

Key specifications

• Interface: SFP28 (both ends)
• Data rate: 25 Gbps
• Length: 3 m
• Cable type: Direct Attach Copper (DAC)
• Typical applications: Short-range connections between devices with SFP28 ports

How to use

Ensure both devices have compatible SFP28 ports and support 25Gbps DAC modules. With equipment powered off or following hot-plug guidance from the vendor, insert each SFP28 connector into the corresponding port until it latches. Verify link status in device management interfaces and configure link speed or negotiation settings if required.

Recommendations

Use the Extralink SFP28 DAC for short-distance interconnects within racks or between adjacent racks. Avoid routing the cable where excessive bending, compression, or electromagnetic interference may occur. Confirm compatibility with chassis and port firmware if interoperability issues arise.
