BlueOptics ET6402-AOC-3M-BO InfiniBand Fibre Optic Cable 3m QSFP Male/Male

The BlueOptics ET6402-AOC-3M-BO InfiniBand Fibre Optic Cable 3m QSFP Male/Male is a 3‑meter active optical cable (AOC) with QSFP male connectors on both ends, designed for high-speed data transmission in data centre and networking environments. The cable integrates a transmitter and receiver on each end and uses multimode fibre to support protocols such as Ethernet and Fibre Channel over Ethernet at data rates up to 40 Gbit/s over the 3 m link. It is built to the QSFP/MSA form factor for compatibility with hardware that supports QSFP AOC connections.

Advantages

The integrated optical transceivers at both ends reduce the need for separate SFP/QSFP modules and simplify cabling while maintaining consistent optical signal conversion. The multimode fibre construction and AOC design provide low-latency, high-throughput links suitable for short-reach interconnects inside racks or between adjacent racks. Compliance with QSFP form-factor interoperability guidelines improves compatibility with supported network switches, routers and storage devices.

Suitable for

• Short-reach high-speed links within racks and between adjacent racks
• 40 Gbit/s Ethernet and Fibre Channel over Ethernet interconnects
• High-performance computing clusters and server-to-switch connections
• Data centre uplinks and switch-to-switch connections where QSFP AOC is supported

Key specifications

• Length: 3 metres
• Connector type: QSFP (male) on both ends
• Type: Active Optical Cable (AOC) with integrated transmitter and receiver
• Fibre type: Multimode fibre
• Supported data rate: up to 40 Gbit/s over the 3 m link
• Form factor: QSFP (compliant with QSFP/MSA interoperability)

How to use

Ensure both devices to be connected support QSFP AOC connections and the target protocol (for example 40 Gbit/s Ethernet or Fibre Channel over Ethernet). Power down or follow hot‑swap guidelines for your hardware as required by the vendor, align the QSFP connectors with the ports and insert the cable until the connector latch engages. Verify link status on connected devices and check hardware diagnostics to confirm that the AOC is recognized and operating at the expected data rate.

Usage recommendations

Use the cable for short-distance interconnects inside racks or between adjacent racks. Avoid excessive bending near the connector ends, maintain recommended minimum bend radii for multimode AOCs, and keep the optical interfaces clean and protected when not connected. Confirm compatibility with your switch, router or storage platform before deployment.
