## Summary description

The BlueOptics QFX-QSFP-DAC-5M-BL is a 5-meter InfiniBand/fibre optic cable with QSFP connectors. Designed for high-speed data transfer, it features male/male connectors for easy connectivity. Ideal for data centers and networking applications, this cable ensures reliable performance and low latency.

## Long description

The BlueOptics QFX-QSFP-DAC-5M-BL is a 5 metre direct attach cable (DAC) with QSFP-to-QSFP male connectors designed for short-reach high-speed data links. It is a passive 40GBase-CR4 twinax copper type using 30 AWG conductors and follows MSA-compliant QSFP interfaces. The cable supports Ethernet, FCoE, Fibre Channel and InfiniBand applications up to 40 Gbit/s across a 5 m distance and is intended for use in rack and adjacent-rack interconnects in data centre environments.
Advantages
The cable offers low latency and low power consumption typical of passive DAC solutions and provides a cost-effective option for short-distance 40 Gbit/s connections. Manufactured using components from established connectivity suppliers and tested for compatibility with major hardware platforms, the design emphasises reliability and long service life for continuous operation in networking and storage installations.
Suitable for
 40 Gbit/s switch-to-switch connections in racks
 Router and switch uplinks across adjacent racks
 High-speed connections between storage systems and servers
 InfiniBand links and other low-latency cluster interconnects
Key specifications
 Cable type: passive twinax copper (Direct Attach Cable)
 Connector type: QSFP (QSFP-to-QSFP), male/male
 Length: 5 metres
 Data rate: up to 40 Gbit/s (40GBase-CR4)
 Conductor size: 30 AWG
 Standards: MSA-compliant QSFP interface
 Supported protocols: Ethernet, FCoE, Fibre Channel, InfiniBand (up to 40 Gbit/s)
How to use
Install by inserting each QSFP male connector into the QSFP port of the networking devices to be linked, ensuring a secure mating until the connector latch engages. Use this cable for short-distance, high-bandwidth links inside racks or between adjacent racks where both endpoints support passive QSFP DACs. No external power or additional modules are required for passive operation; compatibility with the device firmware and QSFP port settings should be confirmed prior to deployment.
Usage recommendations
For reliable operation, route the cable to avoid sharp bends and mechanical strain; maintain a minimum bend radius recommended for twinax cable construction. Verify that connected hardware officially supports passive QSFP DACs and the 40GBase-CR4 interface. For critical deployments, use tested samples to confirm compatibility with the target switches, routers or storage systems.
