BlueOptics Q28-AOC-15M-PT-BO InfiniBand Fibre Optic Cable 15m QSFP28 Male

The BlueOptics Q28-AOC-15M-PT-BO InfiniBand fibre optic cable 15m QSFP28 male is a 15-metre active optical cable designed for high-speed, short- to medium-reach connections in data centre and high-performance computing environments. The cable integrates QSFP28 male connectors on both ends, supporting InfiniBand transport and enabling multi-lane 100Gbps-class links where devices accept QSFP28 interfaces. Its fibre-optic construction reduces electromagnetic interference and power dissipation compared with equivalent copper interconnects while keeping connector compatibility with QSFP28 ports.

Advantages

This active optical cable provides high aggregate bandwidth and low-latency transmission suitable for demanding server-to-switch and switch-to-switch links. The optical medium ensures galvanic isolation and lower signal attenuation over the 15 m length. Using QSFP28 male terminations facilitates direct connection to a range of network and compute equipment without additional transceivers. The cable’s form factor simplifies rack cabling and helps maintain predictable signal integrity for InfiniBand deployments.

Suitable for

• Server-to-switch connections in data centres requiring high throughput
• Switch-to-switch aggregation links in leaf-spine topologies
• High-performance computing clusters using InfiniBand interconnects
• Short- to medium-reach fibre runs within server rooms and equipment racks

Key specifications

• Length: 15 metres
• Connector type: QSFP28 male on both ends
• Interface standard: InfiniBand-compatible optical link
• Transmission medium: active optical fibre
• Typical use case: high-bandwidth, low-latency interconnects for data centre equipment

How to use

Ensure both endpoints support QSFP28 connections and that InfiniBand or compatible QSFP28 interfaces are enabled on connected devices. Route the cable within the rack avoiding sharp bends; maintain the manufacturer’s minimum bend radius for optical fibre to prevent attenuation. Insert each QSFP28 male connector into the corresponding port until it seats securely. Verify link status and performance via device management interfaces and monitor for errors during initial operation.

Recommendations

Handle the cable by the connector housings, avoid excessive bending or pulling, and use appropriate cable management to reduce strain. For critical links, monitor link health and keep spare cables for rapid replacement where uptime is essential.
