InfiniBand/fibre optic cable BlueOptics 330-3966-BL 3 m SFP+ Male/Male

The BlueOptics 330-3966-BL is a 3 m InfiniBand/fibre optic cable with SFP+ male connectors on both ends. Designed for short-distance, high-speed interconnects, this cable supports 10G data rates and is suitable for linking switches, servers and storage within racks and between adjacent racks. The cable implements a Direct Attach style connection and is intended for environments where low latency, low power consumption and reliable physical connectivity are required.

Advantages

The cable provides a straightforward, passive SFP+ to SFP+ connection that supports Ethernet, FCoE, Fibre Channel and InfiniBand protocols up to 10 Gbit/s over a 3 m reach. Its twinax construction with 30 AWG conductors and MSA-compliant SFP+ terminations ensures interoperability with hardware that supports standard SFP+ direct attach cables. The passive design keeps power draw low and reduces potential points of failure compared with active solutions, while quality components and testing help provide consistent compatibility and extended service life.

Suitable for

• Interconnecting network switches and top-of-rack devices within data center racks
• Linking servers to storage or network interface cards supporting SFP+
• Short-distance high-speed links in server rooms and telecommunications closets
• Environments requiring low-latency, low-power direct attach connections

Key specifications

• Length: 3 meters
• Connector type: SFP+ male to SFP+ male
• Supported data rate: up to 10 Gbit/s
• Cable type: passive twinax (copper) suitable for 10GBase-CR
• Conductor gauge: 30 AWG
• Compatibility: MSA-compliant SFP+ interfaces supporting 10GBase-CR, Ethernet, FCoE, Fibre Channel and InfiniBand

How to use

Ensure both devices have SFP+ ports that support passive direct attach copper (DAC) cables and that the required protocols and link speeds are enabled in device firmware or software. Insert each SFP+ connector into the corresponding SFP+ slot until it latches, then verify link negotiation and speed in the device management interface. For cross-rack connections, route the cable to avoid sharp bends and mechanical strain; the 3 m length is intended for short interconnects and rack-to-rack adjacency.

Recommendations

Use the cable for short-distance, rack-level connections where passive SFP+ DACs are supported. Avoid installation in pathways exposed to tight bends or compression, and verify vendor documentation for third-party compatibility with specific switch, router or storage models before deployment.
