BlueOptics Q28-AOC-15M-CI-BO InfiniBand fibre optic cable 15m QSFP28 Male

The BlueOptics Q28-AOC-15M-CI-BO InfiniBand fibre optic cable 15m QSFP28 Male is a 15-metre active optical cable engineered for high-speed, low-latency links in data center and high-performance computing infrastructures. With QSFP28 male connectors on both ends, this cable supports wide-bandwidth transmission suitable for modern InfiniBand environments and provides a compact, flexible connection option for short to medium reach interconnects between switches, servers and storage systems.

Advantages

This QSFP28 InfiniBand cable combines the signal integrity of fibre optics with the convenience of a direct attach form factor, delivering high data rates with reduced electromagnetic interference. The 15 m length provides extended reach compared to direct-attach copper while maintaining lower power consumption and heat generation compared with comparable electrical solutions. The cable’s design supports simplified installation in dense rack environments and helps maintain predictable performance for latency-sensitive applications.

Suitable for

• High-performance computing clusters and InfiniBand fabrics
• Interconnects between top-of-rack and leaf/spine switches
• Server-to-server and server-to-storage links within data centers
• Low-latency applications such as database replication and HPC simulations

Key specifications

• Connector type: QSFP28 male on both ends
• Length: 15 metres
• Transmission medium: active fibre optic
• Intended protocol: InfiniBand (QSFP28 form factor)
• Use case: short- to medium-reach data center interconnects
• Physical characteristics: flexible cable assembly suitable for cable management in racks

How to use

Install the BlueOptics QSFP28 cable by aligning each QSFP28 male connector with the corresponding port on your switches, servers or storage devices and insert until it seats securely. Ensure ports are powered down or that hot-plug specifications of your equipment are observed according to manufacturer guidance. Route the cable to avoid sharp bends and maintain recommended bend radius; secure with cable ties or management hardware to prevent strain on the connectors. After installation, verify link status and throughput using device management tools and test appropriate fabric settings for InfiniBand operation.

Recommendations

For reliable long-term performance, avoid repeated unplugging cycles, keep connector end-faces clean and store unused cables in protective packaging. Confirm compatibility with device QSFP28 ports and firmware requirements before deployment and follow data center cabling best practices to preserve signal integrity and airflow.
