DAC Cable BlueOptics DAC10G-2M-BL 2m SFP+ Male/Male

The BlueOptics DAC10G-2M-BL is a 2 m Direct Attach Copper (DAC) cable with SFP+ male connectors at both ends, designed for short-range, high-speed connections in rack and adjacent-rack environments. It supports 10G data rates over a twinax copper medium and is intended for linking switches, servers and storage hardware that accept passive SFP+ DAC links. The cable combines a compact form factor and low latency for straightforward connectivity in data center and enterprise network topologies.

Advantages

This 2 m SFP+ to SFP+ DAC offers a low-power, low-latency physical connection for 10GBase-CR and related protocols over short distances. As a passive twinax solution, it requires no external power or transceiver modules, simplifying installation and reducing operational power draw. The cable's construction and connector design provide reliable electrical signal transfer for common Ethernet, FCoE and compatible storage or clustering applications within the supported distance.

Suitable for

• Connecting SFP+ ports on switches and routers within racks or between adjacent racks
• Direct server-to-switch or server-to-storage links in data centres
• High-throughput short-reach links for Ethernet, FCoE or similar 10G protocols

Key specifications

• Cable length: 2 m
• Connector type: SFP+ (male) on both ends
• Supported data rate: up to 10 Gbps
• Cable type: passive twinax / Direct Attach Copper
• Weight: 0.08 kg
• Colour: black and silver

How to use

Power off or follow hot-swap procedures required by your equipment, then insert each SFP+ connector into the corresponding SFP+ port until it latches. Verify link status on connected devices and confirm the port settings match the intended 10GBase-CR or compatible protocol. If devices require specific configuration (for example link speed, auto-negotiation or port mode), adjust settings in the switch, server or storage firmware/OS accordingly. For removal, release the latch and pull the connector straight out to avoid straining the port.

Recommendations

Use this passive DAC cable for short, fixed connections where a direct copper link is supported by the hardware. Avoid routing the cable near high-heat sources or sharp edges, and maintain reasonable bend radii to preserve signal integrity. Verify device compatibility with SFP+ passive twinax cables and consult switch or server documentation when deploying in mixed-vendor environments.
