InfiniBand/fibre optic cable BlueOptics 74752-1208-BL 2 m SFP+ Male/Male

The BlueOptics 74752-1208-BL is a 2 m InfiniBand/fibre optic direct attach cable with SFP+ male-to-male connectors designed for short-range, high-speed interconnects in racks and adjacent racks. It supports 10G transmission and is suitable for Ethernet, Fibre Channel over Ethernet (FCoE) and InfiniBand environments where SFP+ ports are used. The cable is intended for reliable electrical/twinax connections over a 2 m distance and follows MSA-compliant SFP+ form-factor requirements for straightforward plug-and-play integration with compatible hardware.

Advantages

This 2 m SFP+ male/male direct attach cable provides low-latency, low-power connectivity for short-distance links in data centres and networking racks. As a passive twinax solution, it does not require additional power for signal conversion, offering reduced energy consumption per link. The cable is manufactured to industry MSA standards and uses proven components for consistent signal integrity, long service life and broad cross-vendor compatibility with switches, routers and storage systems that support SFP+ DAC connections.

Suitable for

• Linking switches and servers within a single rack or between adjacent racks
• High-speed 10G Ethernet and FCoE short-reach connections
• InfiniBand and storage networking where SFP+ interfaces are present

Key specifications

• Cable length: 2 metres
• Connector type: SFP+ male to SFP+ male
• Transmission rate: up to 10 Gbit/s
• Cable type: passive twinax (direct attach copper)
• Wire gauge: 30 AWG
• Form factor: MSA-compliant SFP+ DAC

How to use

Ensure both network devices have SFP+ ports that support passive DAC twinax cables. Power off devices or follow hot-plug guidelines from the hardware vendor, then insert each SFP+ connector into the corresponding port until it latches. Verify link status via the device management interface and configure network settings as required for Ethernet, FCoE or InfiniBand. For safe removal, follow the vendor’s instructions to avoid port or connector damage.

Usage recommendations

Use this 2 m passive SFP+ DAC for short-range connections only; for longer distances, choose active optical cables or fibre solutions. Avoid sharp bends and excessive tension on the cable, maintain bend radius per manufacturer guidance, and keep connectors clean to preserve signal quality. Confirm compatibility with your specific hardware platform before deployment.
