InfiniBand/fibre optic cable BlueOptics CBL-0456L-BL 2 m SFP+ Male/Male

The BlueOptics CBL-0456L-BL is a 2 m InfiniBand/fibre optic cable with SFP+ male-to-male connectors designed for high-speed short-range links. It is suitable for use in racks and between adjacent racks where low-latency, reliable 10 Gbps-class connections are required. The cable implements SFP+ connectivity and a twinax-style direct attach construction appropriate for Ethernet, Fibre Channel over Ethernet (FCoE) and InfiniBand applications up to 10 Gbit/s over a 2 m distance.

Advantages

This 2 m SFP+ cable provides a compact, low-latency connection with passive twinax characteristics and low power consumption. Manufactured to industry MSA guidelines and assembled using high-quality components, it is compatible with major networking platforms that support SFP+ direct attach cables. The cable’s construction and component selection aim to ensure consistent signal integrity for short-range interconnects and a long service life under normal data center operating conditions.

Suitable for

• Interconnects between servers, switches and storage in rack and adjacent-rack environments
• 10GBase-CR Ethernet links and short-range SFP+ direct attach connections
• FCoE and InfiniBand links up to 10 Gbit/s over 2 m distance

Key specifications

• Connector type: SFP+ male to SFP+ male
• Length: 2 metres
• Applicable data rates: up to 10 Gbit/s
• Cable type: passive direct attach / twinax-style construction
• Wire gauge: 30 AWG
• Typical applications: Ethernet, FCoE, Fibre Channel, InfiniBand (short-range)

How to use

Install the cable by inserting each SFP+ connector into the SFP+ port of the corresponding devices until the latch engages. Ensure both ends are seated fully and supported by the equipment’s retention mechanisms. Use the cable for short intra-rack or adjacent-rack connections where the hardware explicitly supports passive SFP+ direct attach twinax cables. Verify link status and speed in the host or switch management interface after connection.

Recommendations

For reliable operation, route the cable to avoid tight bends and maintain the manufacturer’s minimum bend radius. Confirm hardware compatibility with passive SFP+ twinax cables in device documentation before deployment. For high-availability installations, consider testing a sample link and monitoring temperature and link stability under typical load conditions.
