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

The BlueOptics SFP28-DAC-3M-SP 3m Male/Male is a 3-meter direct attach copper (DAC) cable engineered for low-latency, high-bandwidth connections between compatible SFP28 ports. Designed for short-reach interconnects in data centers and high-performance networking environments, this cable uses fixed male SFP28 connectors on both ends to provide a stable physical link for 25 Gbps Ethernet and other SFP28-compatible applications. The cable is supplied in black and has a lightweight construction suitable for dense rack deployments.

Advantages

The BlueOptics SFP28 DAC cable offers a simple, passive interconnect solution that eliminates the need for separate transceivers and fiber patching for short distances. Its fixed male-to-male SFP28 terminations reduce latency and provide consistent electrical performance. The 3 m length balances reach and manageability for common rack-to-rack or shelf-to-shelf connections, while the compact cable diameter supports tidy cable routing in constrained environments.

Suitable for

• Short-reach interconnects between switches, routers and servers with SFP28 ports
• Top-of-rack to aggregation switch connections in data centers
• High-performance computing clusters requiring low-latency links
• Test lab setups and equipment interconnections where 25 Gbps links are needed

Key specifications

• Connector type: SFP28 male on both ends
• Length: 3 meters
• Throughput support: up to 25 Gbps per lane (SFP28)
• Cable type: direct attach copper (DAC), passive
• Colour: black
• Weight: approximately 0.08 kg

How to use

Insert each SFP28 male connector firmly into the corresponding SFP28 port on your networking equipment until the latch engages. Ensure both devices support passive SFP28 DAC connections and that firmware or compatibility settings allow direct attach copper modules. Route the cable to avoid sharp bends and stress points; maintain recommended bend radius to preserve signal integrity. For disconnection, depress the latch and pull the connector straight out to avoid damaging the port.

Recommendations

Use this 3 m DAC cable for short-distance links within racks or between adjacent racks. Avoid prolonged exposure to temperatures or mechanical stress outside manufacturer guidance, and verify device compatibility if vendor compatibility lists are required by your environment.
