AOC CBO 100G QSFP28 active optical cable, 20 m

The AOC CBO 100G QSFP28 active optical cable, 20 m is a factory-terminated fiber solution with QSFP28 connectors engineered for 100 Gigabit Ethernet links. The cable provides a fixed 20‑metre optical connection between QSFP28 ports on switches, routers, servers and other network appliances. As an active optical cable (AOC), it integrates optical transceivers and a lightweight fiber assembly to deliver high data rates with low latency and minimal electromagnetic interference, while eliminating the need for separate transceivers and patch cords.

Advantages

This 20 m AOC supports native 100G signals with QSFP28 compatibility, offering a plug-and-play connection that simplifies installation and reduces rack congestion. The integrated design lowers power consumption compared with some discrete transceiver plus patch-cord combinations and reduces signal loss over the fixed short-reach distance. The optical link is immune to EMI and provides consistent performance in electrically noisy environments.

Suitable for

• Short-reach aggregation links between data centre switches
• Interconnects between servers and top-of-rack or spine switches
• High-speed links for network appliances and storage systems
• Environments where low latency and reduced EMI are required

Key specifications

• Connector type: QSFP28 to QSFP28
• Nominal data rate: 100 Gbps
• Cable type: active optical cable (AOC) with integrated transceivers
• Fixed length: 20 metres
• Application: short-reach 100G interconnects in data centres and enterprise networks
• Latency: low, suitable for latency-sensitive traffic
• EMI performance: immune to electromagnetic interference

How to use

Install the cable by inserting each QSFP28 connector into corresponding QSFP28 ports on compatible devices. Ensure links are powered and interface settings match the expected 100G configuration on both ends; many devices will auto-negotiate when a compatible cable is used. Route the cable within the rack to avoid sharp bends and maintain the minimum bend radius specified by the manufacturer. No separate transceivers or patch cords are required; the assembly is factory-terminated and ready for immediate use.

Usage recommendations

For reliable operation, verify compatibility with the host equipment's QSFP28 port and firmware policies, avoid exceeding the specified bend radius, and maintain cleanliness of connector housings during installation. Use the cable for direct 100G short-reach connections up to 20 m within data centre or lab environments.
