## Summary description

The BlueOptics QFX-SFP-DAC-3MA is a 3 m InfiniBand/fibre optic cable with SFP+ connectors. It features male connectors and is designed for high-speed data transmission. Ideal for connecting devices in data centers or networking environments.

## Long description

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.
Usage 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.
