AOC CBO QFX-QSFP-AOC-5M 5m Active Optical Cable (QSFP+ to QSFP+)

AOC CBO QFX-QSFP-AOC-5M 5m Active Optical Cable (QSFP+ to QSFP+) is a pre-terminated, factory-tested short-reach optical link that connects QSFP+ ports over a 5-metre distance. Designed for data center topologies, this active optical cable converts electrical QSFP+ signaling to optical transmission within the cable assembly to deliver high-bandwidth, low-latency connectivity between switches, servers and storage devices. The compact QSFP+ connectors and flexible sheath make it suitable for dense rack environments where reliable high-speed links are required.

Advantages

The cable eliminates the need for separate transceivers and patch cords, simplifying installation and cable management while reducing electromagnetic interference. Active optical technology provides better signal integrity over five metres compared with equivalent copper direct-attach options, enabling stable 40Gbps-class connections with reduced power consumption and heat generation in confined spaces. Factory termination and testing ensure consistent performance and interoperability with compatible QSFP+ ports.

Suitable for

• Top-of-rack and spine switch interconnects in data centers
• Server-to-switch high-speed links and server stacking
• Storage network connections and SAN aggregation
• Short-reach links inside racks and between adjacent racks

Key specifications

• Connector type: QSFP+ to QSFP+
• Length: 5 metres
• Physical form: pre-terminated active optical cable (AOC)
• Supported data rate: designed for 40Gbps-class QSFP+ links
• Signal medium: optical fiber with active transceiver electronics in the cable
• Typical use environment: data center racks and telecom equipment cabinets

How to use

Install the AOC by inserting each QSFP+ connector into the corresponding QSFP-compatible port on network switches, servers, or storage appliances until the latch engages. No separate transceivers or fiber termination are required. Verify link status using the host device LEDs or management interface and confirm negotiated speed and lane configuration. Route the cable to avoid sharp bends and maintain manufacturer-recommended minimum bend radius to preserve optical performance.

Usage recommendations

Use this 5m active optical cable in short-reach scenarios inside racks or between adjacent racks where QSFP+ ports are available. Avoid excessive bending, pulling, or exposure to liquids and ensure compatibility with the equipment vendor's supported cable types for optimal interoperability.
