SFP28 DAC-kabel BlueOptics SFP28-DAC-2M-SO 2m stekker/stekker

The BlueOptics SFP28-DAC-2M-SO 2m Male/Male is a 2‑metre SFP28 direct attach copper (DAC) cable designed for short‑reach, high‑speed connections between compatible network devices. With male SFP28 connectors on both ends, this cable provides a low‑latency, low‑power physical link suitable for 25 Gigabit Ethernet ports and similar high‑performance interfaces in data centres and server rooms.

Advantages

This SFP28 DAC cable offers a compact, cost‑effective solution for short-distance interconnects. Its fixed copper construction delivers stable signal integrity without the need for transceivers, reducing power consumption and overall system cost. The male/male connectors ensure direct compatibility with SFP28 ports, and the 2 m length balances reach and cable management in rack environments.

Suitable for

• Interconnecting 25 GbE switches and servers within the same rack or adjacent racks
• High‑performance computing clusters requiring low latency links
• Top‑of‑rack to aggregation switch connections in data centres
• Testbench and lab environments for network equipment validation

Key specifications

• Connector type: SFP28 male on both ends
• Length: 2 metres
• Media: direct attach copper (DAC)
• Supported link speed: 25 Gigabit Ethernet (SFP28)
• Latency: low, suitable for latency‑sensitive applications
• Power: lower power consumption compared with optical transceiver plus fiber solutions

How to use

Insert each SFP28 male connector into an available SFP28 port on the devices to be linked, ensuring the latch engages and the connector seats fully. Verify link status on both devices and configure network interfaces as required by your equipment. For best results, route the cable to avoid tight bends and excessive tension; the fixed copper cable requires gentle handling to preserve signal integrity.

Recommendations

Use this 2 m SFP28 DAC cable for short‑reach rack connections where a reliable, low‑latency 25 GbE link is required. Keep the cable within recommended bend radius, avoid running parallel to high‑power electrical lines, and verify compatibility with device firmware or vendor compatibility lists when strict interoperability is needed.
