InfiniBand/fibre optic cable BlueOptics SP-CABLE-FS-QSFP+1-BL 1 m QSFP Male/Male

The BlueOptics SP-CABLE-FS-QSFP+1-BL is a 1 m InfiniBand/fibre optic direct attach cable with QSFP male-to-male connectors. Designed for short-reach, high-speed links in data centres and rack environments, this QSFP-to-QSFP cable supports up to 40 Gbit/s transmission and is suitable for Ethernet, FCoE, Fibre Channel and InfiniBand applications where a passive direct attach twinax or equivalent solution is required. The cable offers a compact connection for adjacent rack units and top-of-rack deployments while maintaining mechanical compatibility with QSFP ports.

Advantages

This 1 m QSFP male/male cable provides a fixed, low-latency connection with simple plug-and-play installation and no external power requirement. The cable’s passive design reduces power consumption and potential points of failure compared with active transceiver solutions. Manufactured to Multi-Source Agreement (MSA) physical specifications and using high-quality components, it delivers stable performance for short-distance, high-bandwidth links and long operating life.

Suitable for

• High-speed links between switches and routers in adjacent rack units
• Top-of-rack to aggregation switch connections in data centres
• Direct server-to-switch or switch-to-switch connections at 40 Gbit/s
• Environments running Ethernet, FCoE, Fibre Channel or InfiniBand protocols

Key specifications

• Cable length: 1 metre
• Connector type: QSFP male to QSFP male
• Maximum data rate: up to 40 Gbit/s
• Application: short-reach direct attach twinax/fibre optic link for rack environments
• Design: passive direct attach (low power, low latency)
• Compliance: designed to MSA mechanical and electrical interface specifications

How to use

Insert each QSFP connector into the corresponding QSFP port on your hardware until the connector latches. Ensure devices are powered and software/firmware support passive DAC or QSFP direct attach connections for the chosen protocol. Verify link status and configured speed in the device management interface. For secure operation, avoid sharp bends and excessive tension on the cable and ensure connectors are free from dust before insertion.

Recommendations

Use this 1 m QSFP male/male cable for short-distance connections inside racks or between adjacent racks. Confirm device compatibility with passive direct attach QSFP connections and follow vendor guidelines for firmware and interface configuration. Store and handle the cable to avoid kinks and protect connector ends when not in use.
