InfiniBand/fibre optic cable BlueOptics OS6860-CBL-100-BL 1 m QSFP Male/Male

The BlueOptics OS6860-CBL-100-BL is a 1 m InfiniBand/fibre optic cable with QSFP connectors on both ends in a male/male configuration. Designed for short-reach high-speed links, this cable supports up to 40 Gbps data rates over direct-attach twinax connections and is suitable for rack-to-rack or in-rack connections in data centres and network equipment that support QSFP to QSFP interconnects.

Advantages

This 1 m QSFP male-to-male cable provides a compact, low-latency connection for high-density network environments. Its passive twinax construction offers low power consumption and a straightforward physical connection without active electronics, which reduces complexity and failure points. The cable’s 30 AWG conductor size and QSFP interfaces make it compatible with equipment that accepts standard QSFP direct-attach cables and designed transmission protocols.

Suitable for

• Short-distance high-speed links between switches and routers within racks
• Connections between servers and storage systems supporting QSFP interfaces
• InfiniBand, Ethernet and Fibre Channel applications up to 40 Gbps where QSFP direct-attach is supported

Key specifications

• Length: 1 metre
• Connector type: QSFP male to QSFP male
• Topology: Direct attach twinax (passive)
• Maximum data rate: up to 40 Gbps (per supported application/port)
• Conductor gauge: 30 AWG
• Colour: Blue

How to use

Confirm that both devices support QSFP direct-attach twinax cables and the intended protocol (InfiniBand, Ethernet, Fibre Channel). Align each QSFP connector with the corresponding port and insert until the latch engages. Avoid forcing the connector; when removing, release the latch before pulling the cable straight out. Route the cable to minimise sharp bends and mechanical strain, keeping bend radius within manufacturer recommendations.

Recommendations

Use this cable for short, high-throughput links in racks or between adjacent racks where passive QSFP twinax is supported. Test compatibility with your specific hardware and firmware to ensure full 40 Gbps operation; keep the cable free from tight bends and mechanical stress to maintain signal integrity and lifetime.
