Cabo AOC 40G BlueOptics 40G-AOC-QSFP3M-BO 3m QSFP macho-macho

The BlueOptics 40G-AOC-QSFP3M-BO is a 3-meter active optical cable with QSFP male connectors on both ends, designed for high-speed data transmission in short-reach environments. This cable supports 40 Gigabit Ethernet links over a single QSFP interface and is intended for direct connectivity between compatible switches, servers, and network appliances. Its plug-and-play design eliminates the need for additional transceivers while maintaining low latency and stable bandwidth for dense networking setups.

Advantages

The active optical construction reduces electromagnetic interference and signal loss across the 3 m span while keeping power consumption low compared with some electrical alternatives. Dual QSFP male connectors provide a compact, standardized interface that simplifies cabling in racks and patch panels. The cable’s lightweight assembly and factory-terminated connectors ensure consistent optical performance and simplified installation without field termination.

Suitable for

• Interconnecting QSFP-enabled switches and routers within racks and between adjacent racks
• High-performance computing clusters and server-to-switch links
• Data centre aggregation and spine-leaf topologies requiring 40 Gbps links

Key specifications

• Length: 3 m
• Connector type: QSFP male to QSFP male
• Data rate: 40 Gbps
• Cable type: Active optical cable (AOC)
• Typical use: Short-reach, intra-rack and adjacent-rack connectivity
• Colour: Aqua and silver
• Weight: 0.07 kg

How to use

Power down devices only if required by your hardware vendor, then insert each QSFP male connector into the corresponding QSFP slot until it clicks into place. Ensure that both ends are fully seated and that port LEDs indicate an active link. Configure the network devices according to your switch or server documentation to enable the 40 Gbps interface. For removal, press the connector release mechanism and withdraw the cable straight out to avoid damaging ports.

Recommendations

Store and route the 3 m cable with gentle bends only, respecting the manufacturer’s minimum bend radius. Avoid tight kinks, excessive pulling force, and exposure to liquids or high temperatures. Use this active optical cable in environments with compatible QSFP ports and follow equipment vendor guidelines for firmware and port configuration to ensure interoperability.
