## Summary description

The BlueOptics 720205-B21-BO is a 7 m InfiniBand/fibre optic cable featuring QSFP connectors. It is designed for high-speed data transmission and reliable connectivity in data centers and networking environments.

## Long description

The BlueOptics 720205-B21-BO is a 7 m InfiniBand/fibre optic active optical cable (AOC) with QSFP to QSFP connectors designed for high-speed data transmission in data centers and professional networking environments. It supports 40GBASE-SR4 class applications over multi-mode fiber and integrates optical transmitter and receiver modules on each end to transfer optical signals according to the transmission protocol.
Advantages
The cable provides a pre-assembled QSFP-to-QSFP link that eliminates the need for separate transceivers and patching, reducing insertion loss and simplifying installation. Built to MSA-aligned mechanical and electrical specifications, the BlueOptics 7 m AOC is intended to deliver consistent 40 Gbit/s connectivity and supports digital diagnostic monitoring (DDM/DOM) for real-time reporting of parameters such as supply voltage, laser bias current, output power, input power and temperature when the host platform supports these functions.
Suitable for
High-speed switch-to-switch and switch-to-server connections within data centers
Storage system interconnects requiring 40 Gbit/s links
Short-reach multi-mode fiber links up to 7 meters in rack and cabinet environments
Key specifications
Cable length: 7 meters
Connector type: QSFP to QSFP
Supported data rate: up to 40 Gbit/s (40GBASE-SR4 class applications)
Media: multi-mode fiber (active optical cable with integrated Tx/Rx)
Digital diagnostics: DDM/DOM support for monitoring optical and electrical parameters (host support required)
How to use
Ensure both devices have QSFP ports that support 40G connectivity and, if required, DDM/DOM functionality. Align the QSFP connectors with the host port and insert each end firmly until the latch engages. Power on the connected devices and verify link status via the host system management interfaces. Use the host diagnostics or network management tools to read DDM/DOM values for live monitoring if supported by the hardware.
Usage recommendations
Install the cable in a clean environment and avoid tight bends; follow the manufacturer’s minimum bend radius for fiber cabling. Verify compatibility with the target QSFP ports according to the host vendor’s documentation before deployment. Where possible, use the cable in short intra-rack or adjacent-rack runs to achieve optimal 40G performance and minimal latency.
