BlueOptics 5CN56-BL InfiniBand fibre optic cable 5 m SFP+ Male Male

The BlueOptics 5CN56-BL InfiniBand fibre optic cable is a 5 m connection cable with SFP+ male-to-male connectors designed for short-range high-speed links in rack and data centre environments. It supports 10 Gigabit-class data transmission and is suitable for low-latency fabrics such as InfiniBand, Ethernet and related storage and networking protocols when used with compatible SFP+ ports. The cable is intended as a reliable interconnect for switches, servers and storage systems that accept SFP+ direct-attach or compatible transceiver-style connections.

Advantages

This SFP+ cable provides a fixed 5 m link length that simplifies rack cabling and avoids the need for separate transceivers and patch cords. As a direct-attach style solution it offers low power consumption and low latency compared with active optical transceivers, while maintaining the mechanical andElectrical connection standards expected of SFP+-compatible interconnects. The product is manufactured to industry interface guidelines to ensure predictable signal performance in supported hardware platforms.

Suitable for

• Short-distance server-to-switch and switch-to-switch connections inside racks
• High-performance computing clusters and InfiniBand fabrics
• Storage networks and converged Ethernet/FCoE uplinks supporting 10 G speeds
• Environments where low latency and low power consumption are important

Key specifications

• Cable type: SFP+ male to SFP+ male direct-attach style cable
• Length: 5 metres
• Supported link speed: up to 10 Gbit/s per link
• Application protocols: Ethernet, InfiniBand, FCoE and compatible storage/network protocols
• Construction: twinax/direct-attach passive design for short-range electrical transmission
• Connector format: SFP+ form-factor compatible plugs on both ends

How to use

Insert each SFP+ connector into the appropriate SFP+ port on the devices to be linked, ensuring the latch(s) engage and the connectors are fully seated. Verify that the network hardware supports passive direct-attach or SFP+ compatible cables and that the firmware/driver settings allow the selected link speed and protocol. After physical installation, check link status and interface configuration on both endpoints and perform any required network configuration such as VLAN, MTU and bonding setup.

Recommendations

Use the cable for short interconnects within the same rack or between adjacent racks, avoid routing through cable trays or areas that expose the cable to sharp bends; respect the minimum bend radius specified by the manufacturer. Ensure connected devices officially support SFP+ passive/direct-attach solutions to guarantee compatibility and stable operation.
