AOC CBO QSFP-H40G-AOC30M-AL 30m active optical cable (QSFP+ to QSFP+, 30 m)

AOC QSFP-H40G-AOC30M-AL is a 30 meter active optical cable engineered for QSFP+ to QSFP+ connections that support 40 Gbps link speeds. This factory-terminated AOC replaces longer copper runs with a lightweight, low-latency optical assembly that provides immunity to electromagnetic interference and stable signal integrity over extended distances. The cable is intended for high-density environments where reliable, high-throughput interconnects are required between servers, switches and other QSFP+-equipped networking devices.

Advantages

The active optical construction delivers consistent 40 Gbps performance with lower power and weight compared with equivalent copper cables, while also minimizing insertion loss and latency. Factory termination ensures standardized optical alignment and reduces installation time. Optical transmission offers immunity to EMI and crosstalk, making the cable suitable for environments with high electrical noise. The 30 m length extends reach beyond typical copper direct-attach limits while maintaining the plug-and-play convenience of QSFP+ connections.

Suitable for

• Data center switch-to-switch interconnects
• High-speed server-to-switch links
• Patch and spine links in leaf-spine topologies
• Equipment racks where EMI immunity and reduced weight are required

Key specifications

• Connector type: QSFP+ to QSFP+
• Length: 30 meters
• Data rate: 40 Gbps aggregate
• Cable type: Active optical cable (AOC)
• Optical properties: factory-terminated multimode optical assembly designed for low insertion loss
• Environmental tolerance: immunity to electromagnetic interference
• Typical use: short‑reach data center interconnects

How to use

Install the AOC by inserting each QSFP+ connector into the corresponding QSFP+ port on network devices until the latch engages. Ensure that devices are powered down or that hot-plugging is supported and recommended by the device vendor before insertion or removal. Route the cable to avoid sharp bends and mechanical stress; maintain the manufacturer’s minimum bend radius and avoid tight cable ties. Verify link status on both ends after installation and check device LEDs or management interfaces to confirm a 40 Gbps link is negotiated.

Recommendations

For reliable operation, handle the cable by the connector housings and protect the ends from contamination when not in use. Avoid routing with power cords or sources of heavy electromagnetic noise when possible, even though the optical link is immune to EMI. Confirm QSFP+ compatibility with your hardware vendor and update device firmware if required to ensure full support for active optical assemblies.
