Cavo SFP28 DAC BlueOptics SFP28-DAC-5M-SW 5 m connettore maschio/maschio

The BlueOptics SFP28-DAC-5M-SW is a 5-meter SFP28 Direct Attach Copper (DAC) cable with male connectors on both ends, engineered for high-speed 25Gbps interconnects in data center and enterprise networks. This passive copper assembly provides a compact, low-latency physical link for short-reach connections between switches, routers, and servers. With a durable outer jacket and standardized SFP28 form-factor, the cable is intended for straightforward installation in equipment that supports SFP28 DAC interfaces.

Advantages

This SFP28 DAC cable offers low latency and stable signal integrity for 25Gbps links while avoiding the need for separate transceivers and fiber patching for short distances. Its fixed 5 m length simplifies cabling planning and reduces clutter in rack environments. The male-to-male connectors ensure compatibility with SFP28 ports, and the copper construction provides power-efficient transmission compared with active optical solutions for equivalent short-reach connections.

Suitable for

• Short-reach connections between switches inside racks and across adjacent racks
• Connecting top-of-rack (ToR) switches to aggregation switches
• Direct server-to-switch high-speed links for storage and compute nodes

Key specifications

• Data rate: 25 Gbps (SFP28 compatible)
• Cable type: Direct Attach Copper (DAC), passive
• Length: 5 m
• Connector type: SFP28 male to SFP28 male
• Outer colour: Black
• Weight: 0.08 kg

How to use

Ensure both network devices support SFP28 DAC connections and are powered down or follow hot-swap guidelines from the equipment vendor. Align each male SFP28 plug with the corresponding SFP28 port and insert until the latch engages. After connection, verify link status via device LEDs or network management interfaces. For removal, disengage the latch and pull the connector straight out to avoid stressing the port.

Recommendations

Use this 5 m passive SFP28 DAC cable for short-distance 25Gbps links inside racks or between adjacent racks. Avoid tight bends or kinks in the cable, maintain proper cable management to reduce strain on ports, and operate within the ambient temperature range specified by your network equipment. If deploying across longer distances or needing optical isolation, consider optical transceivers and fiber instead.
