AOC Cable BlueOptics AOC-Q-Q-40G-3M-CT-BO 3m QSFP Male/Male

The BlueOptics AOC-Q-Q-40G-3M-CT-BO is a 3 m Active Optical Cable (AOC) with QSFP male connectors on both ends designed for 40G high-speed links. Built for multimode fiber applications, this AOC integrates transmitters and receivers in each QSFP module and conforms to 40GBASE-SR4 electrical and optical signalling. The cable provides a low-latency, low-power connection suitable for high-density rack environments, data center switches, routers and storage systems that accept QSFP 40G optics.

Advantages

The BlueOptics AOC-Q-Q-40G-3M-CT-BO offers plug-and-play installation with hot-pluggable QSFP connectors and eliminates the need for separate transceivers and external fiber patch cords. Its integrated optical transceivers reduce signal loss and ensure consistent 40G throughput over the 3 m reach. The compact, factory-terminated design helps maintain predictable channel performance and simplifies cabling in high-density network racks.

Suitable for

• Data centre switch-to-switch connections within the same rack or adjacent racks
• High-performance computing clusters requiring 40G links
• Interconnects between routers, storage arrays and blade servers
• Low-latency, short-reach Ethernet or Fibre Channel links up to 3 m

Key specifications

• Length: 3 meters
• Connector type: QSFP male to QSFP male
• Data rate: up to 40 Gbps (40GBASE-SR4 compatible)
• Fiber type: multimode fiber with integrated optical transceivers
• Application: short-reach server, switch and storage interconnects
• Form factor: active optical cable (factory-terminated AOC)

How to use

Install the BlueOptics AOC-Q-Q-40G-3M-CT-BO by inserting each QSFP connector into the corresponding QSFP port on your network devices until the connector latches. No additional SFP/QSFP transceivers or fiber patch cords are required. Verify that both endpoints support 40GBASE-SR4 signalling and that device firmware permits the use of third-party AOC modules if applicable. After connection, check link status on the devices and confirm 40 Gbps operation through device diagnostics or management interfaces.

Recommendations

Use this 3 m AOC for short-reach, high-bandwidth interconnects inside racks or between adjacent racks. Avoid sharp bends and mechanical strain on the cable and QSFP connectors; follow vendor-recommended bend radius and handling procedures. If device compatibility restrictions exist, test the cable in a controlled environment before large-scale deployment.
