SFP28 DAC Cable BlueOptics SFP28-DAC-3M-SO 3m Male/Male

The BlueOptics SFP28-DAC-3M-SO is a 3-meter direct attach copper (DAC) cable with SFP28 male connectors on both ends, engineered for 25Gbps short-reach links between network equipment. Built for data center and enterprise rack environments, this SFP28 DAC cable supports low-latency, high-bandwidth connections between switches, servers and storage devices while maintaining signal integrity over a 3 m copper channel.

Advantages

This SFP28 DAC cable offers straightforward plug-and-play installation with no additional transceivers required, reducing power consumption compared with active optical links. The twinax copper construction provides stable performance for short-distance 25GbE links and minimizes latency and jitter. Its standardized SFP28 form factor ensures physical compatibility with SFP28 ports and helps preserve rack density and cable management simplicity.

Suitable for

• Connecting 25GbE switches and servers within racks or adjacent racks
• Top-of-rack to leaf switch uplinks in data centers
• High-throughput, low-latency links for storage arrays and compute clusters
• Short-reach interconnects in enterprise network closets

Key specifications

• Length: 3 meters
• Connector type: SFP28 male to SFP28 male
• Data rate: 25 Gbps (per link)
• Cable type: Twinax / direct attach copper (DAC)
• Color: Blue
• Typical use: Short-reach, high-speed interconnects

How to use

Insert each SFP28 connector into the corresponding SFP28 port on the network devices until the latch engages. Ensure ports are powered down or follow hot-swap guidelines of your hardware vendor if connecting live systems. After connection, verify link status in the device management interface and confirm negotiated speed and polarity. Route the cable to avoid sharp bends and maintain proper airflow within the rack.

Recommendations

Use this 3 m SFP28 DAC cable for short-distance, high-bandwidth links where low latency and reduced power consumption are priorities. Avoid exceeding the recommended bend radius, and keep the cable away from strong electromagnetic interference sources. For longer distances or flexible routing needs, consider active optical solutions.
