InfiniBand optický kabel BlueOptics SFPP-DAC-3M-NA-BL SFP+ SFP+ DAC 3m samec/samec

The BlueOptics SFPP-DAC-3M-NA-BL InfiniBand fibre optic cable SFP+ SFP+ DAC 3m Male/Male is a 3-metre direct attach cable designed for short-distance high-speed links in racks and between adjacent racks. It features SFP+ connectors on both ends and supports 10 Gbit/s data transmission for Ethernet, FCoE, Fibre Channel and InfiniBand protocols where passive DAC twinax copper connections are supported by the host devices. The cable is MSA-compliant and intended for use with switches, routers, storage systems and servers that accept SFP+ direct attach connections.

Advantages

This 3 m SFP+ to SFP+ cable offers low latency and low power consumption typical of passive DAC solutions and a straightforward plug-and-play connection without active transceiver components. MSA compliance ensures mechanical and electrical interoperability with a wide range of hardware platforms. The passive twinax construction provides a cost-effective option for short-range links while using high-quality components to improve durability and long service life.

Suitable for

• Connecting top-of-rack switches to adjacent switches or servers
• Interconnecting storage arrays and host adapters within the same rack
• Short-distance links in data center patching and network aggregation
• Environments requiring 10 Gbit/s bandwidth over short copper twinax cable runs

Key specifications

• Connector type: SFP+ (male) on both ends
• Cable length: 3 metres
• Data rate support: up to 10 Gbit/s
• Transmission medium: passive twinax (direct attach cable)
• Compliance: SFP+ MSA electrical and mechanical specifications
• Typical power consumption: near-zero for passive operation
• Suitable for Ethernet, FCoE, Fibre Channel and InfiniBand protocols

How to use

Install the BlueOptics SFPP-DAC-3M-NA-BL by inserting each SFP+ connector into the SFP+ port of the devices to be linked until the latch engages. Ensure both devices support passive SFP+ DAC cables and that the ports are configured for the intended protocol and speed. No separate power or transceiver modules are required. Verify link status via device LEDs or management interfaces and test throughput with standard network diagnostics after installation.

Recommendations

Use this 3 m passive DAC cable for short, intra-rack or adjacent-rack connections where 10 Gbit/s links are required. Avoid bending the cable beyond manufacturer bend-radius limits, keep connections free of strain, and ensure both connected devices explicitly support passive SFP+ twinax DACs to guarantee compatibility and reliable operation.
