InfiniBand/fibre optic cable BlueOptics 81Y8296-BL 3 m SFP+ Male/Male

The BlueOptics 81Y8296-BL is a 3 m InfiniBand / fibre optic direct attach cable with SFP+ male-to-male connectors designed for short-range, high-speed links in racks and between adjacent racks. It supports electrical 10GBase-CR transmission over a passive twinax copper assembly with 30 AWG conductors, MSA-compliant connectors and compatibility with hardware platforms that accept SFP+ DACs. The cable is intended for 10 Gbit/s Ethernet, FCoE, Fibre Channel and InfiniBand applications over a 3 meter distance and is produced using quality components to ensure reliable signal transmission and long service life.

Advantages

The cable offers a compact, low-latency connection with passive operation and low power consumption, making it suitable for dense rack deployments and short interconnect runs. MSA-compliant SFP+ connectors ensure interoperability with a wide range of switches, routers and storage systems that support SFP+ direct attach cables. Built from selected components and tested for compatibility, the assembly provides predictable performance and an extended lifetime compared to lower-quality alternatives.

Suitable for

• Short-range 10 Gbit/s connections between servers and switches within racks
• Inter-rack links across adjacent racks in data centres
• Fibre Channel and FCoE connections where SFP+ DACs are supported
• InfiniBand and high-speed networking equipment with SFP+ ports

Key specifications

• Length: 3 meters
• Connector type: SFP+ male to SFP+ male (MSA-compliant)
• Transmission type: Passive twinax copper (10GBase-CR compatible)
• Conductor gauge: 30 AWG
• Data rate: up to 10 Gbit/s
• Supported protocols: Ethernet, FCoE, Fibre Channel, InfiniBand

How to use

Insert each SFP+ connector into the corresponding SFP+ port on the devices to be linked, ensuring connectors are fully seated and any retention latches engage. Use the cable for short-distance connections (up to 3 m) between SFP+ ports on switches, routers, servers or storage systems that support passive DACs. Verify that the target hardware and firmware allow passive SFP+ direct attach cables; in some environments a specific vendor whitelist or software setting may be required.

Usage recommendations

Route the cable to avoid tight bends and mechanical strain; maintain bend radius recommended by the hardware vendor to preserve signal integrity. Keep cable runs short and free of electromagnetic interference sources for optimal performance. For redundant or critical links, consider testing compatibility in your specific hardware configuration before large-scale deployment.
