## Summary description

The BlueOptics 7Z57A04256-BO is a 1 m InfiniBand/fibre optic cable featuring QSFP connectors on both ends. It is designed for high-speed data transmission and is suitable for connecting devices in data centers and high-performance computing environments. The cable is durable and provides reliable performance for demanding applications.

## Long description

The BlueOptics 7Z57A04256-BO is a 1 m InfiniBand / fibre optic active optical cable (AOC) with QSFP male connectors on both ends. Designed for high-speed links in data centers and high-performance computing environments, this QSFP-to-QSFP AOC follows MSA-compliant form factors and supports 40G data rates over multimode fibre for short-reach connections. The pre-assembled cable integrates optical transmitter and receiver modules on each end to deliver reliable signal transfer without the need for field termination or patching.
Advantages
The cable offers a compact, factory-terminated AOC solution that reduces installation time and avoids attenuation and connector contamination associated with separate patchcord assemblies. Built to be compatible with major hardware that supports the corresponding 40GBASE-SR4 QSFP AOC standard, this BlueOptics product is intended to provide stable 40 Gbit/s connectivity for Ethernet, Fibre Channel over Ethernet and similar high-speed protocols. Digital diagnostic monitoring (DDM/DOM) support enables remote measurement of key optical parameters when the host device provides that capability.
Suitable for
Interconnecting QSFP ports between switches, routers and storage systems in data centers
High-performance computing clusters requiring low-latency 40G links
Short-reach fibre runs inside racks and between adjacent racks
Key specifications
Connector type: QSFP male to QSFP male
Length: 1 metre
Data rate: up to 40 Gbit/s (40GBASE-SR4 applications)
Media: multimode fibre AOC (active optical cable with integrated transceivers)
Form factor: QSFP MSA-compliant
Digital Diagnostic Monitoring (DDM/DOM): supported when host hardware supports MSA SFF-8472 functions
How to use
Install the BlueOptics QSFP AOC by aligning and inserting each QSFP connector into the corresponding QSFP port on your devices until the latch engages. Use in equipment that officially supports QSFP 40G AOCs and verify device compatibility in the hardware documentation. If your host supports DDM/DOM, monitor supply voltage, laser bias current, transmit/receive power and temperature through the management interface to ensure link health. Handle the cable by the connector housings and avoid tight bends at the transition to the cable to preserve optical performance.
Usage recommendations
Ensure the connected hardware supports QSFP 40G AOC modules and the DDM/DOM feature if you need remote diagnostics. Maintain bend radius recommendations for multimode AOCs, keep connector latches free of debris, and route the cable to avoid mechanical stress or repeated sharp bends to preserve long-term performance.
