InfiniBand/glasvezelkabel SFP+ BlueOptics UACC-DAC-SFP10-2M-BL 2 m

The BlueOptics UACC-DAC-SFP10-2M-BL is a 2 meter SFP+ direct attach cable (DAC) designed for short-reach, high-speed connections in data centers and network racks. It features SFP+ connectors on both ends and supports 10G data rates for Ethernet, FCoE, Fibre Channel and InfiniBand applications where passive twinax copper cabling is appropriate. The cable is intended for linking switches, routers and storage hardware across adjacent rack positions and short inter-rack distances.

Advantages

This 2m SFP+ DAC offers a low-latency, low-power wired connection without active electronics in the cable itself, enabling reduced complexity and a lower failure rate compared with active transceiver solutions. Manufactured to MSA-compatible dimensions and using high-quality components for conductors and connector housings, it provides reliable 10G connectivity in supported hardware platforms while maintaining a cost-effective total cost of ownership for short-distance links.

Suitable for

• 10G connections between switches within the same rack or adjacent racks
• Direct server-to-switch or storage-to-switch links over short distances
• Fibre Channel, FCoE and InfiniBand links that accept SFP+ passive DACs
• High-density rack installations where low power and low latency are required

Key specifications

• Connector type: SFP+ to SFP+
• Length: 2 meters
• Data rate support: up to 10 Gbit/s
• Cable type: passive twinax copper (30 AWG conductors)
• MSA-compliant form factor for SFP+ interfaces
• Typical applications: Ethernet, FCoE, Fibre Channel, InfiniBand (short reach)

How to use

Insert each SFP+ connector into the corresponding SFP+ port on network devices until the latch engages. Ensure both connected devices officially support passive SFP+ DACs for correct operation. Route the cable along rack channels or cable management paths to avoid sharp bends; maintain minimum bend radius and avoid tensile stress on the connectors. No external power or configuration is required for the cable itself, but verify link settings and transceiver compatibility on connected hardware if a link is not negotiable.

Recommendations

Use this 2m passive SFP+ DAC for short-distance, high-throughput links where low latency and low power consumption are priorities. Confirm device compatibility with passive DACs and follow rack cable management practices to preserve connector integrity and ensure long-term reliability.
