InfiniBand/fibre optic cable BlueOptics X6595-R6-BL 3 m QSFP Male/Male

The BlueOptics X6595-R6-BL is a 3 m InfiniBand/fibre optic direct attach cable with QSFP male-to-male connectors designed for high-speed interconnects in data centers and networking racks. It supports 40G data rates over a 3-meter link, compatible with hardware platforms that accept 40GBase-CR4 or QSFP to QSFP direct attach cables. The cable is specified as a passive 40G twinax copper type with 30 AWG conductors and MSA-compliant QSFP interfaces, intended for short-range electrical signal transmission between switches, routers, storage systems and other compatible devices.

Advantages

The BlueOptics X6595-R6-BL provides reliable 40G connectivity with low latency and low power consumption typical of passive direct attach cables. Built to industry MSA standards, it uses high-quality components for robust electrical performance and long operational life. Its 3 m length is suitable for connections within racks or between adjacent racks, offering a cost-effective alternative to active optical transceivers for short-distance links.

Suitable for

• 40G QSFP to QSFP connections within rack or to adjacent rack devices
• High-bandwidth switch-to-switch and switch-to-storage links
• InfiniBand, Ethernet, FCoE and Fibre Channel applications up to 40 Gbps over 3 m
• Data center top-of-rack and aggregation layer cabling where passive DACs are supported

Key specifications

• Cable type: passive twinax copper direct attach
• Connector type: QSFP male to QSFP male
• Length: 3 meters
• Data rate: up to 40 Gbps (40GBase-CR4 compatible)
• Wire gauge: 30 AWG
• Standards: MSA-compliant QSFP interface
• Typical applications: Ethernet, InfiniBand, FCoE, Fibre Channel (short-reach)

How to use

Ensure both devices support passive QSFP twinax direct attach cables and the intended 40G protocol. Insert each QSFP connector firmly into the QSFP port on the respective devices until the latch engages. Verify link status on connected devices and configure network interfaces according to your hardware vendor guidelines. For removal, release the connector latch and pull the connector straight out to avoid stress on the cable or ports.

Recommendations

Use this cable for short-distance, high-bandwidth links inside racks or between adjacent racks. Avoid sharp bends and do not exceed the recommended bend radius. Keep the cable away from heat sources and route it to prevent mechanical strain on connectors. Confirm device compatibility with passive DACs and 40GBase-CR4 operation before deployment.
