InfiniBand/fibre optic cable BlueOptics 02310QPR-BL 5 m SFP+

The BlueOptics 02310QPR-BL 5 m InfiniBand/fibre optic cable with SFP+ connectors on both ends is designed for short-reach, high-speed connections in racks and adjacent rack rows. It supports 10G-class protocols including Ethernet, FCoE and InfiniBand, and is intended for linking switches, routers, storage arrays and servers where low latency and reliable throughput are required. The cable implements an SFP+ to SFP+ connection and follows common MSA-compliant electrical/twinax characteristics for passive direct-attach applications over a 5 meter distance.

Advantages

This 5 m SFP+ cable provides a cost-effective, low-power and low-latency connection suitable for high-density data center environments. Constructed with high-quality components and designed to meet MSA specifications, it offers reliable interoperability with major hardware platforms that support the corresponding 10GBase-CR direct-attach interface. Passive construction eliminates active electronics in the cable, reducing power consumption and failure points while keeping installation simple.

Suitable for

• Interconnecting switches within a rack or between adjacent racks
• Server-to-switch and storage-to-switch 10G links
• Fibre Channel over Ethernet (FCoE) and InfiniBand short-reach connections
• High-density rack deployments requiring SFP+ direct-attach cabling

Key specifications

• Connector type: SFP+ to SFP+
• Cable length: 5 meters
• Supported data rates: up to 10 Gbit/s
• Transmission medium: passive twinax / short-reach electrical link characteristics for 10GBase-CR
• Conductor gauge: 24 AWG equivalent construction for twinax cable
• Compliance: MSA-aligned SFP+ electrical interface

How to use

Ensure both devices have SFP+ ports that support passive direct-attach 10GBase-CR twinax connections. With devices powered down or following hot-swap guidelines from the hardware vendor, insert each SFP+ connector into the corresponding port until it latches. Verify the link status in the device management interface and confirm negotiated speed and protocol (10G Ethernet, FCoE or InfiniBand) are active. If any compatibility settings are required by the host or switch firmware, apply them according to the manufacturer’s documentation.

Recommendations

Use this passive SFP+ cable for short, high-bandwidth connections in data centers and avoid routing where the cable may be bent beyond manufacturer bend-radius recommendations. For reliable long-term operation, pair the cable with devices that explicitly support 10GBase-CR or passive SFP+ twinax DAC links and follow equipment firmware compatibility notes.
