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

The BlueOptics Q28-AOC-15M-FR-BO InfiniBand fibre optic cable 15m QSFP28 Male is a 15-metre active optical cable engineered for high-throughput, low-latency connections in dense networking environments. With QSFP28 connectors on both ends, this cable supports InfiniBand links and high-speed Ethernet interconnects where a compact, flexible and electrically silent optical link is required. It is intended for short to mid-range connections inside racks and between adjacent racks in data centres and high-performance computing clusters.

Advantages

This fibre optic cable delivers high bandwidth and low latency performance typical of QSFP28 interfaces while eliminating the need for separate transceivers. The active optical construction provides better signal integrity and reduced electromagnetic interference compared with copper alternatives. Its 15 m length offers flexibility for rack-to-rack cabling without sacrificing performance, and the compact QSFP28 form factor allows dense port deployment in switches and servers.

Suitable for

• Interconnects between servers and switches in data centres
• High-performance computing (HPC) cluster links
• Storage area network (SAN) and NVMe-over-Fabrics backbones
• Low-latency trading and research network segments

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Cable type: Active optical cable (AOC)
• Length: 15 metres
• Interface: InfiniBand-compatible, supports high-speed serial lanes
• Performance: Designed for low latency, high-bandwidth data transfer
• Operating environment: Suitable for rack and data centre use

How to use

Install the QSFP28 connectors into compatible QSFP28 ports on your switches, servers or host adapters. Ensure ports are powered down or follow hot-plug guidelines from your hardware vendor when inserting or removing the cable to avoid link negotiation issues. Use the 15 m length to route between adjacent racks or equipment rows, keeping bend radii within manufacturer recommendations and avoiding sharp kinks. Verify link status and negotiated speed in your host or switch management interface after installation.

Recommendations

Handle the cable by the connector housings when inserting or removing. Maintain recommended bend radius and avoid crushing or tight staples. Use this AOC in environments where electrical isolation or low EMI is needed and pair it with devices that support QSFP28 interfaces for full performance.
