SFP28 DAC Cable BlueOptics SFP28-DAC-5M-VA 5m Male/Male

The BlueOptics SFP28-DAC-5M-VA is a 5-metre SFP28 direct attach copper (DAC) cable with male SFP28 connectors on both ends. Designed for 25 Gigabit Ethernet and compatible high-speed interconnects, this cable provides a direct, low-latency connection between switches, network interface cards, and storage controllers. Its fixed length and copper construction make it a cost-effective solution for short-reach links in data centres and high-performance computing racks.

Advantages

This SFP28 DAC cable delivers predictable performance with minimal signal loss over its 5-metre span and supports high bandwidth required for 25GbE and certain InfiniBand setups. The male-to-male SFP28 terminations ensure plug-and-play compatibility with standard SFP28 ports, eliminating the need for transceivers and reducing power consumption compared with optical links. The robust copper construction and moulded connectors provide mechanical stability for rack-mounted equipment and frequent reconfigurations.

Suitable for

• Short-reach server-to-switch and switch-to-switch connections within racks or adjacent racks
• High-performance computing clusters and storage area networks requiring low latency
• 25 Gigabit Ethernet links and compatible InfiniBand interconnects
• Environments where cost-effective, low-power direct attach solutions are preferred

Key specifications

• Connector type: Male SFP28 on both ends
• Cable type: Direct attach copper (DAC)
• Length: 5 metres
• Supported data rate: 25 Gbit/s per lane (suitable for 25GbE)
• Typical use: Short-reach interconnects in data centres and server racks

How to use

Install the cable by inserting each SFP28 male connector into the corresponding SFP28 port until the latch engages. Ensure that both network devices are powered down or that hot-swap support is enabled and follow your equipment vendor’s instructions for installing SFP28 DAC cables. After connection, verify link status via switch or host management interfaces and confirm negotiated data rate and link health.

Usage recommendations

Use this 5m SFP28 DAC cable for short-distance links inside the same rack or between adjacent racks to maintain low latency and reduce power usage. Avoid sharp bends and excessive cable strain; keep the cable within the recommended bend radius and secure it to prevent mechanical stress on the connectors. Check compatibility with your network equipment to ensure proper recognition and full performance.
