BlueOptics CBL-0490L InfiniBand/fibre optic cable 1 m QSFP Male/Male

The BlueOptics CBL-0490L InfiniBand/fibre optic cable 1 m QSFP Male/Male is a short, high-performance connection cable designed for dense networking environments. It supports InfiniBand and fiber optic links using QSFP form-factor connectors on both ends, delivering a compact 1 metre span intended for rack-to-rack, switch-to-switch or server-to-switch interconnects where low latency and high throughput are required.

Advantages

This 1 m QSFP Male/Male cable provides reliable high-speed data transfer with minimal signal loss across a short distance. Its QSFP connectors ensure compatibility with modern InfiniBand and QSFP-capable transceivers and ports, while the single-metre length reduces cable clutter and improves airflow in racks. The cable is lightweight and suitable for high-density cabling scenarios, offering stable optical performance for data centre and enterprise networking applications.

Suitable for

• Short-distance connections between switches, servers and storage in racks
• InfiniBand fabric links in high-performance computing (HPC) clusters
• High-density data centre cabling where QSFP ports are available
• Replacing or extending existing QSFP-to-QSFP optical links

Key specifications

• Cable type: Fibre optic / InfiniBand-compatible optical cable
• Connector type: QSFP male to QSFP male
• Length: 1 m
• Application: Short-reach high-speed links for data centre and networking equipment
• Physical: Compact design for high-density installations

How to use

Install the BlueOptics CBL-0490L by aligning QSFP connectors with the corresponding QSFP ports on your devices and gently inserting until the connectors engage. Ensure devices are powered off or ports are configured for hot-plugging according to manufacturer guidelines before connecting. After physical installation, verify link status and configure network interfaces or InfiniBand fabrics as required by your networking hardware and software.

Recommendations

For best performance, use this 1 m QSFP cable in short-reach links within the same rack or adjacent racks. Avoid tight bends and excessive pulling; maintain manufacturer-recommended bend radius. Match connector types and port capabilities (QSFP speed and protocol support) to ensure compatibility and expected throughput.
