## Summary description

The BlueOptics Q28-AOC-50M-QL-BO is a 50-meter InfiniBand fibre optic cable featuring QSFP28 connectors on both ends. It provides high-speed data transfer and is ideal for data centers and high-performance computing environments. The male/male configuration ensures compatibility with various devices, making it a reliable choice for connecting servers and switches.

## Long description

The BlueOptics Q28-AOC-50M-QL-BO InfiniBand fibre optic cable 50m QSFP28 Male/Male is an active optical cable designed for high-speed interconnects in data centres and high-performance computing environments. At 50 metres in length, this QSFP28-to-QSFP28 AOC supports low-latency, high-bandwidth links between servers, switches and storage systems where copper cabling is impractical or distance exceeds the limits of passive copper assemblies.
Advantages
This InfiniBand fibre optic cable delivers high data throughput and electrical isolation while maintaining low power draw thanks to integrated optics. The QSFP28 male-to-male configuration ensures direct compatibility with QSFP28 ports used in modern 100GbE and InfiniBand HDR environments. Active optical design removes the need for transceivers in each port and maintains signal integrity over longer distances compared with equivalent copper solutions.
Suitable for
 Rack-to-rack and row-to-row interconnects in data centres
 High-performance computing clusters and server farms
 Switch-to-switch uplinks and spine-leaf network fabrics
 Connections between storage arrays and compute nodes
Key specifications
 Cable type: Active Optical Cable (AOC)
 Connector type: QSFP28 male to QSFP28 male
 Length: 50 metres
 Supported protocols: InfiniBand and compatible 100Gb/s QSFP28 interfaces
 Latency: low-latency design suitable for HPC and low-jitter networks
 Power: integrated optical transceivers with low power consumption
 Build: fibre-optic construction for extended reach and electrical isolation
How to use
Install the cable by aligning and inserting each QSFP28 male connector into the corresponding QSFP28 port on devices, ensuring the latch engages securely. Route the cable to avoid tight bends and kinks; follow the minimum bend radius recommended by your rack and cabling guidelines. Once connected, verify link status on both endpoints and configure interface settings on network equipment if required. For best results, use in compatible InfiniBand or 100GbE-capable ports and check device firmware or driver support for active optical cable detection.
Usage recommendations
Handle the cable by the connector housings and avoid pulling on the fibre jacket. Maintain a gentle bend radius during installation, keep connectors clean and protected when not in use, and store spare cables in a dry, dust-free environment. Confirm compatibility with your equipment and firmware to ensure optimal performance in data centre and HPC applications.
