BlueOptics 40G-AOC-QSFP50M-BO InfiniBand fibre optic cable 50 m QSFP

The BlueOptics 40G-AOC-QSFP50M-BO InfiniBand fibre optic cable 50 m QSFP is an active optical cable engineered for high-speed short-reach links. With QSFP connectors on both ends and a 50 metre jacketed length, the cable supports multi-gigabit throughput suitable for dense networking setups. It is designed for low-latency environments and offers plug-and-play installation with compatible QSFP ports.

Advantages

This active optical cable delivers consistent 40 Gbit/s aggregate bandwidth while reducing electromagnetic interference compared with copper alternatives. The integrated transceivers and optical fibres provide lower power dissipation per port in many configurations and maintain signal integrity over the 50 m distance. The QSFP-to-QSFP form factor simplifies cabling in racks and switches, supporting compact routing and reduced connector count.

Suitable for

• Interconnecting switches and routers in data centre top-of-rack and spine-leaf architectures
• High-performance computing clusters and InfiniBand fabrics
• Storage area networks (SAN) and server-to-switch links requiring 40 Gbit/s
• Short-reach optical links where low latency and EMI immunity are required

Key specifications

• Interface: QSFP (QSFP+ / QSFP28 compatible port dimensions for QSFP form factor)
• Nominal data rate: 40 Gbit/s aggregate
• Cable type: Active optical cable with integrated transceivers
• Length: 50 metres
• Transmission medium: multimode optical fibre within an AOC assembly
• Latency: designed for low-latency interconnects in short-reach environments
• Operating environment: indoor rack and data centre use

How to use

Install the cable by inserting each QSFP connector into the corresponding QSFP port on your networking equipment until it seats securely. Ensure both devices are powered off or port negotiation follows the vendor guidelines if hot-plugging. Check compatibility with your switch, router or host adapter for supported link speeds and any vendor-specific requirements. Route the cable to avoid tight bends and mechanical stress; follow rack cable management best practices to maintain airflow and access.

Usage recommendations

Verify QSFP port support for 40 Gbit/s operation and any required firmware or driver updates before deployment. Use appropriate cable management accessories to prevent bend radius violations and avoid physical strain on connectors. For mission-critical environments, test links after installation and monitor error counters to confirm stable operation.
