## Summary description

The BlueOptics X6559-R6-BL is a 5 m InfiniBand/fibre optic cable featuring QSFP connectors on both ends. It is designed for high-speed data transmission, ensuring reliable connectivity in data centers and networking environments. The male/male configuration allows for easy integration with compatible devices, making it ideal for connecting switches, servers, and storage systems.

## Long description

The BlueOptics X6559-R6-BL InfiniBand/fibre optic cable is a 5 m QSFP male-to-male connection designed for high-speed links in data centers and rack environments. It provides a direct connection between compatible QSFP ports on switches, servers and storage systems and supports short-reach 40GBase interconnects using a passive direct-attach twinax copper topology. The cable is intended for environments that require low latency and reliable electrical transmission over a 5 metre distance.
Advantages
This 5 m QSFP to QSFP cable offers a simple plug-and-play connection with QSFP male connectors at both ends and is suitable for short-distance, high-throughput links. Its passive twinax construction results in low power consumption and minimal additional latency compared to active transceiver solutions. The cable conforms to common MSA-compliant 40GBase-CR4 direct attach cable designs, enabling interoperability with hardware platforms that support such interfaces. Robust component selection and testing procedures are reported to deliver consistent electrical performance for rack-to-rack and intra-rack connections.
Suitable for
Connecting QSFP ports on switches and routers within and between adjacent racks
Direct links between servers and storage systems with QSFP interfaces
Short-reach 40G data centre interconnects and top-of-rack aggregation
Key specifications
Cable length: 5 metres
Connector type: QSFP male to QSFP male
Transmission type: passive direct attach (twinax copper) suitable for 40GBase-CR4 and InfiniBand electrical signaling
Wire gauge reference: 30 AWG twinax conductors
Applications supported: Ethernet, FCoE, Fibre Channel, InfiniBand up to 40 Gbit/s over 5 m
How to use
Insert each QSFP male connector into the corresponding QSFP port on the devices to be linked, ensuring the connectors are fully seated and any retention latches are engaged. Verify that both devices support passive 40G direct-attach twinax cables and that firmware or port settings permit the 40GBase-CR4 or equivalent electrical mode. Once connected, check link status indicators on each device to confirm the physical layer is active and negotiate the expected data rate and protocol.
Usage recommendations
Use the cable for short-distance connections (up to 5 m) inside racks or between adjacent racks; avoid sharp bends and excessive pulling during installation. Confirm device compatibility with QSFP passive DAC cables and ensure airflow and cable routing do not obstruct cooling in rack environments.
