## Summary description

The BlueOptics SFP28-DAC-3M-CO is a 3-meter SFP28 DAC cable designed for high-speed data transmission. It features male connectors on both ends, ensuring compatibility with SFP28 ports. Ideal for connecting switches and servers in data centers, it offers reliable performance and durability.

## Long description

The BlueOptics SFP28-DAC-3M-CO is a 3-meter direct attach copper (DAC) cable with SFP28 male connectors on both ends, designed for short-reach, high-speed 25Gbps links between network equipment. Its twin-terminated SFP28 form factor makes it suitable for direct connections between switches, routers and servers that support SFP28 ports. The cable combines a compact physical profile with straightforward compatibility to provide a simple, low-latency interconnect for top-of-rack and adjacent-rack installations.
Advantages
This SFP28 DAC cable delivers a fixed, low-latency copper connection without the need for separate transceivers, reducing component count and power consumption. The 3 m length provides flexibility for rack-to-rack or within-rack runs while avoiding excess slack. With a ruggedized assembly and male SFP28 terminations at each end, the cable offers a reliable physical interface designed for repeated insertion and removal in data center environments.
Suitable for
Short-reach 25Gbps links between switches and servers
Top-of-rack and adjacent-rack interconnects in data centers
High-density network deployments requiring low power and low latency
Key specifications

How to use
Install the BlueOptics SFP28-DAC-3M-CO by inserting each SFP28 male connector into the corresponding SFP28 port on your networking devices until the latch engages. Ensure both devices support 25Gbps SFP28 DAC links and that ports are powered down or follow hot-plug guidelines of the equipment manufacturer if applicable. Verify link status through device management interfaces and monitor for proper speed and duplex settings. To remove, release the connector latch and pull the connector straight out to avoid bending the cable.
Usage recommendations
For reliable operation, use this cable in temperature-controlled rack environments and avoid tight bends near the connector ends. Keep cable runs within the specified 3 m distance and ensure compatibility with your switch or server SFP28 ports. If transceiver firmware or vendor locking is present on your devices, confirm interoperability before deployment.
