## Summary description

The BlueOptics CBL-QSFP-40GE-3M-BO is a 3-meter InfiniBand/fibre optic cable with QSFP connectors. It features male-to-male connectivity, ensuring reliable data transmission for high-speed networking applications.

## Long description

The BlueOptics CBL-QSFP-40GE-3M-BO InfiniBand/fibre optic cable is a 3‑meter active optical cable (AOC) with QSFP to QSFP male connectors. Designed to meet MSA QSFP form‑factor requirements, this BlueOptics cable supports multi‑mode fibre transmission with integrated transmitter and receiver modules at each end. It is intended for high‑speed short‑reach interconnects and is compatible with systems that accept the Dell CBL-QSFP-40GE-3M 40GBASE‑SR4 AOC standard.
Advantages
The cable provides a compact, plug‑and‑play solution for 40G high‑speed links over short distances, reducing the need for separate transceiver modules and patch cords. Integrated optics and QSFP connectors simplify installation and help maintain consistent signal integrity across the full 3 m length. Compatibility with major platforms that support the referenced 40GBASE‑SR4 AOC ensures predictable performance in Ethernet, Fibre Channel over Ethernet or SDH/SONET environments.
Suitable for
 40G short‑reach server-to-switch or switch-to-switch connections within racks or between adjacent racks
 High‑density data centre interconnects where QSFP form‑factor is required
 Environments using Ethernet, Fibre Channel over Ethernet or SDH/SONET at up to 40 Gbps
Key specifications
 Cable type: Active Optical Cable (AOC) with QSFP connectors
 Length: 3 meters
 Connector ends: QSFP male to QSFP male (QSFP to QSFP)
 Rated data rate: up to 40 Gbps (40GBASE‑SR4 compatible)
 Fibre type: multi‑mode fibre with integrated Tx/Rx optics
 Form factor: QSFP MSA compliant
How to use
Insert each QSFP connector into the QSFP ports of the network devices until the connector latches. Ensure devices are powered off or follow hot‑swap guidelines from the device manufacturer if connecting while powered. The cable is plug‑and‑play when used with hardware that supports the compatible 40GBASE‑SR4 AOC; the integrated transceivers handle optical signalling and link negotiation according to the connected devices' capabilities. Confirm link status in device management interfaces after installation.
Usage recommendations
Use this 3 m BlueOptics AOC for short‑reach, high‑density 40G links inside racks or between adjacent racks. Avoid tight bends and excessive pulling force; maintain minimum bend radius for the cable to preserve optical performance. Verify device compatibility with the 40GBASE‑SR4 AOC profile before deployment and perform basic link tests after installation.
