BlueOptics MC2210128-003-BL InfiniBand fibre optic cable 3 m QSFP

The BlueOptics MC2210128-003-BL InfiniBand fibre optic cable 3 m QSFP is a 3-meter high-speed connectivity solution with QSFP-to-QSFP connectors designed for short-range links in data centers and rack environments. It supports InfiniBand and other 40 Gbps-class applications and is intended for direct connections between compatible switches, routers, storage systems and host adapters. The cable uses a twinax / Direct Attach approach suitable for low-latency, high-throughput interconnects where a short fixed-length connection is required.

Advantages

This 3 m QSFP cable provides a compact and reliable link with low power consumption and low latency suitable for dense rack installations. The product is manufactured to MSA-compliant mechanical and electrical specifications to ensure interoperability with major hardware platforms that support QSFP direct attach connections. Using high-quality components and tested assemblies, the cable is intended to offer stable performance and long operational lifetime for professional networking environments.

Suitable for

• Short-range high-speed links between rack-mounted switches and routers
• Direct connections to storage systems and host adapters supporting QSFP
• High-density top-of-rack and adjacent-rack interconnects in data centers
• InfiniBand, Ethernet and Fibre Channel applications up to 40 Gbps on 3 m distance

Key specifications

• Length: 3 meters
• Connector type: QSFP to QSFP (male/male)
• Supported protocols: InfiniBand, Ethernet, Fibre Channel (up to 40 Gbps)
• Cable type: Direct attach twinax (passive DAC) suitable for short distances
• Compliance: MSA-compatible QSFP electrical and mechanical interface
• Typical power consumption: low (passive design)

How to use

Connect each QSFP plug into the corresponding QSFP port on compatible devices, ensuring correct orientation and a secure seating. Use the 3 m length for connections inside a rack or between adjacent racks where fixed short-range links are required. Verify that the hardware and firmware on both ends support passive QSFP direct-attach twinax connections and the intended protocol (InfiniBand, Ethernet or Fibre Channel) before placing the cable into permanent operation. Handle the cable by its connector housings to avoid stressing the conductor assemblies.

Usage recommendations

For reliable operation, confirm device compatibility and supported link modes in the equipment documentation. Avoid excessive bending near the connectors and maintain proper cable routing to prevent mechanical strain. In high-availability environments, consider testing a sample link before wide deployment and keep spare cables available for quick replacement.
