## Long description

The BlueOptics 720202-B21-BL QSFP InfiniBand 5m Black is a 5-meter direct attach cable designed for short-range, high-speed connections in racks and between adjacent racks. Featuring QSFP to QSFP connectors and a passive twinax construction, this cable supports 40GBase-CR4 electrical transmission and is suitable for Ethernet, FCoE, Fibre Channel and InfiniBand applications up to 40 Gbit/s over a 5 m distance. The cable is finished in black and supplied in a male-to-male QSFP configuration for straightforward integration with compatible network hardware.
Advantages
This 5 m direct attach cable provides a cost-effective and energy-efficient way to establish 40 Gbit/s links for short distances in data center and rack environments. Its passive twinax design keeps power consumption and latency low while offering a simple, robust connection with industry-standard QSFP interfaces. The cable is built to industry MSA guidelines and uses high-quality components to deliver dependable performance and extended service life in supported hardware platforms.
Suitable for
Connecting switches and routers within the same rack or adjacent racks
High-speed server-to-switch links in data centers
Storage system interconnects requiring up to 40 Gbit/s
Short-range InfiniBand and Fibre Channel connections
Key specifications
Cable length: 5 m
Connector type: QSFP to QSFP (male-to-male)
Supported protocols: Ethernet, FCoE, Fibre Channel, InfiniBand (up to 40 Gbit/s)
Cable type: passive twinax copper (Direct Attach Cable)
Colour: Black
Typical use case: short-range rack and adjacent-rack links
Power consumption (typical for passive twinax): very low
How to use
Install the cable by inserting each QSFP plug firmly into the QSFP port of the connected devices, ensuring that the ports are compatible with passive 40GBase-CR4 direct attach cables. Route the cable along rack channels or cable managers to avoid sharp bends and mechanical stress. Verify link status on connected devices and confirm negotiated speed and protocol support in the host hardware. Passive twinax cables do not require external power or transceiver modules; compatibility depends on the devices’ support for passive DACs.
Usage recommendations
For reliable operation, use the cable within its intended 5 m distance, avoid tight bending radii, and install it in compatible QSFP ports that explicitly support passive 40GBase-CR4 twinax direct attach cables. Check device documentation for passive DAC support and confirmed protocol compatibility before deployment.
