BlueOptics QFX-SFP-DAC-3MA InfiniBand/fibre optic cable 3 m SFP+ Black

The BlueOptics QFX-SFP-DAC-3MA is a 3 m InfiniBand / fibre optic cable with SFP+ male connectors designed for high-speed data transmission between networking devices. Its 3-metre length and SFP+ interface make it suitable for short to medium range connections in rack-mounted systems, server-to-switch links and other structured networking environments where low-latency, high-throughput links are required.

Advantages

This cable provides a direct SFP+ connection that supports high data rates with reduced latency compared to longer copper or passive connections. The 3 m length balances reach and manageability in data centre racks and networking cabinets. The cable's construction and connector design aim to ensure stable signal integrity and reliable mechanical fit with SFP+ ports.

Suitable for

• Server-to-switch connections in data centres
• Inter-switch links in rack environments
• High-throughput, low-latency connections for storage and compute clusters
• Short-distance links inside networking cabinets or between adjacent racks

Key specifications

• Connector type: SFP+ male connectors at both ends
• Length: 3 metres
• Media: InfiniBand / fibre optic compatible design for high-speed links
• Color: Black housing and cable sheath
• Application: Designed for short to medium range high-bandwidth network connections

How to use

Ensure both devices have compatible SFP+ ports and that the network equipment supports the cable's interface. Power off the ports or follow hot-plug procedures recommended by the device manufacturer, then insert each SFP+ connector firmly into the corresponding port until it latches. Route the cable to avoid sharp bends and mechanical stress, and verify the link status on connected devices after insertion. If necessary, consult device logs and management interfaces to confirm proper negotiation and link speed.

Recommendations

For optimal performance, use the cable within standard rack-bundle practices: avoid tight bends, keep a minimum bend radius as specified by the equipment vendor, and secure the cable to reduce strain. Regularly check connector cleanliness and port compatibility when replacing or adding links.
