InfiniBand/fibre optic cable SFP+ BlueOptics EX-SFP-10GE-DAC-3M-BL 3m Male/Male

The BlueOptics EX-SFP-10GE-DAC-3M-BL is a 3‑meter Direct Attach Cable (DAC) with SFP+ male-to-male connectors designed for short-range high-speed connections in data centre racks and adjacent rack rows. This passive twinax copper cable supports 10GBase-CR electrical signalling and is MSA-compliant, enabling plug-and-play links between switches, routers, storage systems and other network devices that accept SFP+ DAC modules. The cable is specified for InfiniBand, Fibre Channel, Ethernet and FCoE applications up to 10 Gbit/s over a 3 m distance.

Advantages

The cable provides a cost-effective and energy-efficient connection option for short-distance links, with low latency and very low power consumption characteristic of passive DACs. It is manufactured to MSA standards using high-quality components to ensure reliable electrical performance and long operational life. Compatibility testing is performed to ensure proper function in supported hardware platforms, and the standardized SFP+ form factor ensures straightforward installation and replacement.

Key specifications

How to use

Insert each SFP+ connector into the corresponding SFP+ port on the networking devices until the latch clicks. Ensure both endpoints support passive DAC operation and the same transmission protocol (for example, 10GBase‑CR for Ethernet). Verify link status through the device management interface and confirm the negotiated speed is 10 Gbit/s. Handle the cable by the connectors and avoid sharp bends; maintain the minimum bend radius recommended for twinax copper cables to preserve signal integrity.

Recommendations

Use this 3 m passive SFP+ DAC for short-distance rack connections where low latency and low power consumption are priorities. Confirm vendor compatibility for passive DACs on your target hardware and test a sample in your environment if required before large-scale deployment.
