InfiniBand/fibre optic cable BlueOptics 45W3039-IB-BL 5 m SFP+ SFP+ DAC Male/Male

The BlueOptics 45W3039-IB-BL is a 5 m InfiniBand / fibre optic Direct Attach Cable (DAC) with SFP+ connectors on both ends in a male-to-male configuration. Designed for short-range, high-speed links in racks and between adjacent racks, this passive 10GBase-CR twinax copper cable supports up to 10 Gbit/s data rates and is MSA-compliant. It is suitable for connecting switches, routers, storage systems and other network hardware that accept SFP+ DAC connections.

Advantages

This 5 m SFP+ to SFP+ DAC provides low latency and low power consumption typical of passive twinax copper designs. Built to MSA standards with high-quality components and 24 AWG cable construction, it offers reliable electrical signal transmission for short distances while maintaining compatibility with major hardware platforms. The cable is intended to deliver a cost-effective, energy-efficient alternative for high-speed rack-level interconnects.

Suitable for

• Rack-to-rack or intra-rack high-speed links in data centers
• 10G Ethernet, FCoE, Fibre Channel and InfiniBand applications up to 10 Gbit/s
• Direct connections between SFP+ ports on switches, routers and storage arrays

Key specifications

• Length: 5 m
• Connector type: SFP+ to SFP+ (male/male)
• Transmission type: passive twinax copper (DAC)
• Supported data rate: up to 10 Gbit/s
• Cable gauge: 24 AWG
• Compliance: MSA-compliant

How to use

Power down or follow hot-swap procedures recommended by your hardware vendor before inserting or removing SFP+ DACs. Align each SFP+ connector with the corresponding port and insert until it seats securely. Verify the host devices recognize the link and check link/activity LEDs or management interfaces to confirm connectivity. Use this cable for short-distance electrical connections inside racks or between adjacent racks where passive SFP+ DACs are supported.

Recommendations

Use the BlueOptics 45W3039-IB-BL in environments where short, high-speed electrical links are required and where devices explicitly support passive SFP+ DAC cables. Avoid routing the cable near high-interference sources, ensure proper strain relief at connections, and follow vendor guidelines for operating temperature and handling to maximize service life.
