## Summary description

The BlueOptics 7Z57A03546-BO is a 3 m InfiniBand/fibre optic cable featuring QSFP28 connectors. It provides high-speed data transfer with male connectors on both ends, ideal for data centers and high-performance computing environments.

## Long description

The BlueOptics 7Z57A03546-BO is a 3 m InfiniBand/fibre optic active optical cable (AOC) with QSFP28 male connectors on both ends designed for high-speed data transfer in data centers and high-performance computing environments. It conforms to MSA QSFP28 physical interface standards and supports parallel multimode optical transmission for short-reach 100G applications such as 100GBASE-SR4. The cable integrates transceivers at each end to transmit and receive optical signals over multi-mode fiber, offering a pre-assembled, plug-and-play link that avoids patching and reduces connector cleaning and attenuation issues.
Advantages
This 3 m BlueOptics QSFP28 AOC provides a direct 100G-capable optical connection with low latency and immunity to electromagnetic interference, making it suitable for dense networking environments. The cable is manufactured to industry MSA standards and uses tested optical components to ensure interoperability with platforms that support the equivalent Lenovo 7Z57A03546 100G AOC. Integrated digital diagnostics (DDM/DOM, SFF-8472 compatible) enable remote monitoring of key operating parameters such as supply voltage, laser bias current, transmit and receive optical power, and temperature to simplify maintenance and troubleshooting.
Suitable for
100G switch-to-switch connections in data centers
High-performance computing clusters requiring InfiniBand or 100G Ethernet
Storage area network links and high-throughput storage systems
Short-reach rack-to-rack or chassis-to-chassis optical interconnects
Key specifications
Connector type: QSFP28 male to QSFP28 male
Cable type: Active Optical Cable (AOC) using multimode fiber
Nominal length: 3 metres
Supported protocols: 100GBASE-SR4, compatible with 100G Ethernet and Fibre Channel over Ethernet
Digital diagnostics: DDM/DOM support (MSA SFF-8472)
Designed immunity: not susceptible to electromagnetic interference (optical transmission)
How to use
Insert each QSFP28 connector into the corresponding QSFP28 port on the devices to be connected, following the device vendor instructions for handling and insertion. Ensure both host devices support the use of QSFP28 AOCs and, if required, enable or verify DDM/DOM support in the host to access diagnostic information. Handle the cable by the connector housings, avoid tight bends that exceed manufacturer bend-radius recommendations, and keep connector ends protected from dust until installation to maintain optimal signal quality.
Usage recommendations
Verify compatibility with the hardware platform prior to deployment, confirm that the target devices support QSFP28 AOCs and required 100G protocols, and use the DDM/DOM diagnostic data for remote monitoring and preventive maintenance to maximize link availability.
