InfiniBand/fibre optic cable BlueOptics 740-065630-BO 1 m QSFP28 Male/Male

The BlueOptics 740-065630-BO is a 1 m InfiniBand/fibre optic cable with QSFP28 male connectors on both ends. It is engineered to provide high-throughput, low-latency links for data center and enterprise networking environments where reliable, short-reach optical interconnects are required. The single-metre length reduces excess cable slack in dense racks and makes the cable suitable for top-of-rack or server-to-switch connections.

Advantages

This QSFP28 male-to-male fibre optic cable supports high data rates and is compatible with equipment that uses QSFP28 interfaces, enabling multi-lane 100Gbps and similar high-speed configurations. The fibre construction ensures electrical isolation and immunity to electromagnetic interference, while the compact 1 m length aids tidy cable management and minimizes signal loss associated with longer runs. Robust connector housings and precision-polished ferrules help maintain consistent optical performance and reduce insertion loss over time.

Suitable for

• Short-reach links between servers and top-of-rack switches
• InfiniBand interconnects in high-performance computing clusters
• High-density data centre patching and uplinks
• Switch-to-switch connections within a rack

Key specifications

• Length: 1 metre
• Connector type: QSFP28 male to QSFP28 male
• Media: fibre optic suitable for InfiniBand and high-speed Ethernet
• Typical application: short-reach, high-bandwidth interconnects
• Physical colour: blue jacket for easy identification

How to use

Inspect both QSFP28 connectors and the cable jacket for visible damage before installation. Align each male QSFP28 connector with the corresponding device receptacle and insert until the connector engages firmly; follow the device vendor's guidance on connector orientation and latch mechanisms. Ensure rack and patch panel routing keeps bend radii within the fibre manufacturer's recommended limits to prevent microbending losses. Verify link status and error counters from connected devices after installation to confirm optical link integrity.

Usage recommendations

For best results in data centre environments, use this 1 m QSFP28 fibre cable for short-distance connections within a single rack or adjacent racks. Avoid tight bends and compressive forces on the cable; label both ends for easier maintenance and follow standard electrostatic discharge (ESD) precautions when handling optical transceivers and connectors.
