BlueOptics QSFP28-100G-CU1M InfiniBand/fibre optic cable 1 m Black

The BlueOptics QSFP28-100G-CU1M InfiniBand/fibre optic cable 1 m Black is a 1-metre direct-attach cable with male QSFP28 connectors on both ends, engineered for short-reach, high-speed interconnects. It supports 100G data rates over InfiniBand and similar high-bandwidth networking environments, providing a compact and low-latency physical link suitable for rack-to-rack, switch-to-server and switch-to-switch connections in data centers and enterprise networks.

Advantages

This cable delivers consistent 100 gigabit performance with low power consumption and minimal signal loss at short distances. Its QSFP28 form-factor ensures compatibility with equipment that accepts QSFP28 ports, while the fixed copper/fibre construction offers a reliable, maintenance-free connection without the need for separate transceivers. The 1 m length helps reduce cable clutter in dense rack installations and enables predictable latency for latency-sensitive applications.

Suitable for

• High-density data centre top-of-rack and spine connections
• Server-to-switch and switch-to-switch 100G links
• InfiniBand clusters and high-performance computing interconnects
• Short-reach links where low latency and consistent throughput are required

Key specifications

• Connector type: male QSFP28 on both ends
• Nominal data rate: 100 Gbit/s
• Cable length: 1 metre
• Cable colour: black
• Intended use: short-reach direct-attach for high-speed networking

How to use

Install the cable by aligning each QSFP28 plug with the corresponding QSFP28 port on your network equipment and insert until the latch engages. Ensure both connected devices are powered and configured to support a 100G link. Avoid excessive bending or tension on the cable; maintain gentle routing within the rack to prevent strain on connectors. When unplugging, depress the latch mechanism and pull straight out to avoid damaging the plug or port.

Recommendations

Verify compatibility of your switches, servers and adapters with QSFP28 direct-attach cables and confirm firmware or driver settings for 100G operation. For runs longer than 1 metre, consider alternate QSFP28 cable types or active optical assemblies. Store and route the cable to prevent sharp bends and keep it away from heat sources and heavy equipment.
