CBO InfiniBand Active Optical kabel QSFP-AOC-5M-MR-BO 5 m

The CBO InfiniBand Active Optical Cable QSFP-AOC-5M-MR-BO 5 m is an active optical link designed for high-speed QSFP-to-QSFP connections over a fixed 5 metre distance. It provides optical transmission without separate transceiver modules, enabling direct board-to-board and rack-to-rack connections with low latency and galvanic isolation. The cable is intended for use in data centres, high-performance computing clusters and switch-to-switch interconnects where signal integrity and sustained throughput are important.

Advantages

This active optical cable delivers high-bandwidth optical connectivity while eliminating the need for discrete transceivers, reducing component count and simplifying installation. Optical transmission over the 5 m span provides electrical isolation and lowers susceptibility to electromagnetic interference, which helps maintain signal integrity in dense rack environments. The fixed-length design ensures predictable link characteristics and supports low-latency InfiniBand connections typical for HPC and storage fabrics.

Suitable for

• Data centre rack-to-rack interconnects
• High-performance computing (HPC) clusters and node interconnects
• Switch-to-switch links in fabric networks
• Server and storage appliance connections requiring low latency and electrical isolation

Key specifications

• Connector type: QSFP form-factor on both ends suitable for QSFP ports
• Length: 5 metres fixed optical cable
• Cable type: Active optical cable (AOC) for optical signal transmission
• Application: InfiniBand and high-speed fabric interconnects
• Performance characteristics: designed for low latency and high throughput over short datacentre spans
• Electrical properties: provides galvanic isolation between connected devices

How to use

Install the cable by inserting each QSFP connector into the corresponding QSFP port on the network devices, ensuring the retention latch engages. No separate transceiver modules are required; the active optical elements are integrated into the cable assembly. Verify link status and appropriate port configuration on each device after connection. For hot-plug capable equipment, the cable can be connected or removed while devices are powered, subject to the host hardware guidelines.

Recommendations

Route the cable with minimal bending and avoid sharp kinks; maintain the manufacturer’s recommended bend radius to preserve optical performance. Keep connectors and port interfaces free of dust and contamination; use dust caps when ports are not in use. Confirm compatibility of QSFP port settings on switches and host adapters for InfiniBand operation and ensure adequate airflow around connected equipment to prevent thermal issues.
