Cabo de fibra ótica InfiniBand SFP+ BlueOptics UACC-DAC-SFP10-3M-BL 3 m

The BlueOptics UACC-DAC-SFP10-3M-BL is a 3-meter Direct Attach Cable (DAC) with SFP+ connectors designed for short-distance 10G connections in racks and adjacent rack rows. This 10GBase-CR compatible twinax copper cable (30 AWG) supports Ethernet, Fibre Channel over Ethernet (FCoE) and InfiniBand applications up to 10 Gbit/s and is intended for use with hardware platforms that accept SFP+ direct attach solutions. The cable is manufactured to standard MSA dimensions and constructed with quality components for reliable signal transmission and long operational life.

Advantages

The cable offers a cost-effective, low-power passive DAC solution with low latency and straightforward installation. Its passive twinax design requires no external power or active modules and reduces potential points of failure. Built with industry-standard components and tested for compatibility with common vendor platforms, the cable provides stable 10 Gbit/s links for short-reach interconnects within racks and between adjacent racks.

Suitable for

• 10G connections between switches and servers within the same rack or adjacent racks
• High-speed links for storage arrays and SAN interconnects using Fibre Channel or FCoE
• InfiniBand and other low-latency data center links that support SFP+ DACs
• Environments where a low-power, low-latency copper direct attach solution is required

Key specifications

• Connector type: SFP+ to SFP+
• Cable type: Passive twinax copper (DAC), 30 AWG
• Rated data rate: up to 10 Gbit/s
• Length: 3 meters
• Supported protocols: Ethernet, FCoE, Fibre Channel, InfiniBand (where SFP+ DACs are supported)
• Compliance: MSA-compliant mechanical dimensions and electrical signaling for SFP+

How to use

Insert each SFP+ connector into the SFP+ port of the devices you intend to link, ensuring the latch engages. Verify that both connected devices support passive 10GBase-CR DACs and that the appropriate port settings are enabled in the hardware or switch firmware. After physical connection, check link status and negotiated speed in the device management interface to confirm a 10 Gbit/s link. Remove the cable by releasing the connector latch and gently pulling straight out to avoid damaging the port.

Recommendations

Use this 3 m passive SFP+ DAC for short-distance interconnects inside racks or between adjacent racks. Avoid routing the cable near sources of strong electromagnetic interference and maintain bend radii recommended for twinax cables. Ensure connected hardware supports passive DAC operation; otherwise use active optical or active DAC alternatives. For critical installations, test a sample cable with your specific hardware and firmware configuration before large-scale deployment.
