Network Cable BlueOptics EB4K BlueLAN DAC SFP28 SC272701Q1M30 1m Blue

The BlueOptics EB4K BlueLAN DAC SFP28 SC272701Q1M30 1m Blue is a 1-meter direct attach copper cable engineered for high-speed SFP28 connections. Designed for short-reach interconnects in data centers and server racks, this cable provides a reliable physical link for 25 Gbps network ports. Its durable jacket and blue color aid in visual cable management while maintaining signal integrity for demanding, high-throughput environments.

Advantages

This direct attach cable supports SFP28 interfaces and is optimized for 25 Gbps data transmission, enabling low-latency, high-bandwidth links between switches, servers, and storage devices. The fixed 1 m length reduces clutter in dense rack environments and simplifies cable routing. Built with a robust outer jacket and stable connector terminations, it is intended to deliver consistent electrical performance and durability under standard data-center conditions.

Suitable for

• Short-reach connections between SFP28 ports in racks and cabinets
• Interconnects between 25 Gbps switches, servers, and storage nodes
• Cable management where color-coding is required for identification
• High-density installations requiring compact, fixed-length links

Key specifications

• Interface type: SFP28 direct attach copper (DAC)
• Nominal data rate: up to 25 Gbps per lane
• Length: 1 meter
• Connector style: SFP28 compatible plug-to-plug
• Cable color: blue for easy identification
• Application: short-reach, within-rack or adjacent-rack connectivity

How to use

Ensure both devices support SFP28 DAC modules before installation. Power down or follow hot-plug guidelines of your hardware vendor, then insert each connector into the corresponding SFP28 port until it clicks into place. Verify link status on the connected devices and confirm negotiated speeds and link integrity through management interfaces. Route the cable to avoid sharp bends and mechanical strain; the fixed 1 m length is intended for tidy, short-distance connections.

Usage recommendations

For reliable operation, use this cable for intra-rack or neighboring-rack links up to 1 m and avoid exceeding manufacturer-recommended bend radii. Keep connectors free of dust and debris and verify compatibility with switch and server SFP28 port specifications to prevent interoperability issues.
