InfiniBand/fibre optic cable BlueOptics MA-CBL-40G-3M 3m QSFP Male

The BlueOptics MA-CBL-40G-3M 3m QSFP Male is a 3-meter InfiniBand/fibre optic cable engineered for high-speed data transmission between network equipment that supports QSFP interfaces. Designed for use in data centers and high-performance computing environments, this cable provides a reliable physical link for multi-gigabit traffic while maintaining signal integrity over a short to medium distance.

Advantages

This QSFP-to-QSFP cable offers low latency and high bandwidth suitable for 40 Gigabit interconnects. Its factory-terminated connectors ensure consistent electrical and optical performance, and the 3 m length provides a balance between reach and reduced signal loss for rack-to-rack or within-rack connections. The cable's build supports compatibility with devices that accept QSFP form-factor modules and is intended to deliver stable connections under continuous operation.

Suitable for

• Server-to-switch connections in data centers
• High-performance computing clusters
• Switch-to-switch stacking and aggregation
• Short to medium distance trunking within racks or between adjacent racks

Key specifications

• Length: 3 meters
• Interface: QSFP male connectors on both ends
• Supported data rate: 40 Gigabit-class links
• Cable type: InfiniBand / fibre optic compliant for high-speed transmission
• Typical use environment: Data center and HPC installations

How to use

Connect the QSFP connector on one end of the cable to the corresponding QSFP port on the source device and insert the other QSFP connector into the target device port. Ensure ports are powered down or follow your equipment vendor's hot-plug guidelines when inserting or removing QSFP cables. Verify link status and configuration in network management or on the device console to confirm the 40 Gigabit link is negotiated correctly.

Recommendations

Install the cable with gentle bends only, avoiding tight radii that can damage the fibre. Keep connectors capped when not in use to prevent contamination. For best performance, use this cable for connections within racks or between adjacent racks where a 3 m length is appropriate and ensure compatibility with your QSFP-capable equipment.
