InfiniBand/fibre optic cable BlueOptics MA-CBL-40G-1M 1m QSFP Male

The BlueOptics MA-CBL-40G-1M is a 1 meter InfiniBand/fibre optic cable with QSFP male connectors on both ends. Engineered for high-speed data transmission, this cable supports short-range connections within racks and between adjacent network equipment, providing reliable throughput for data centers, server rooms and high-performance computing environments. The single-meter length reduces excess cabling and helps maintain tidy cable management in dense installations.

Advantages

This QSFP-to-QSFP fibre optic cable delivers low-latency, high-bandwidth links suitable for 40 Gbps class connections. The fixed 1 m length minimizes signal loss over short distances and simplifies installation. Male QSFP connectors provide secure mechanical fit and straightforward plug-and-play use. The cable construction is designed to meet common environmental and operational demands found in professional networking environments.

Suitable for

• Short-reach connections between switches, routers and network interface cards in rack environments
• High-performance computing clusters and InfiniBand fabric links
• Data center top-of-rack and server-to-switch cabling
• Laboratory testing setups and equipment interconnects requiring 40 G class links

Key specifications

• Cable type: InfiniBand / fibre optic assembly with QSFP connectors
• Connector gender: QSFP male to QSFP male
• Length: 1 meter
• Supported data rate: designed for 40 G class links
• Typical use: short-range, rack-to-rack or server-to-switch interconnects
• Construction: factory-terminated assembly for plug-and-play installation

How to use

Install the cable by aligning and inserting each QSFP male connector into the corresponding QSFP port on your network devices until the connector latches. Ensure both devices are powered down or follow hot-swap guidelines provided by your hardware vendor if connecting live. Verify link status through device LEDs or management interfaces to confirm an active 40 G link. Route the cable to avoid tight bends and mechanical stress; maintain recommended bend radius to preserve signal integrity.

Recommendations

For optimal performance, use this 1 m QSFP cable for short-distance connections within racks or adjacent rack units. Avoid routing the cable near strong electromagnetic sources and do not exceed recommended bend radius. Check device compatibility for QSFP interfaces and supported speeds before installation, and consult network equipment documentation for hot-plug procedures.
