## Summary description

The BlueOptics Q28-AOC-50M-CI-BO is a 50m InfiniBand fibre optic cable featuring QSFP28 male connectors. It is designed for high-speed data transmission and is ideal for data centers and high-performance computing environments. The cable ensures reliable connectivity and minimal signal loss, making it suitable for demanding applications.

## Long description

The BlueOptics Q28-AOC-50M-CI-BO InfiniBand fibre optic cable 50m QSFP28 Male is a 50-metre active optical cable designed for high-speed InfiniBand connections. It provides a single-cable solution with QSFP28 male interfaces for server-to-switch or switch-to-switch links in environments requiring low latency and high throughput. The cable supports reliable long-reach connectivity with reduced electromagnetic interference compared to copper alternatives and is intended for use in data centers and high-performance computing clusters.
Advantages
This InfiniBand fibre optic cable offers high bandwidth capacity and consistent signal integrity over long distances. As an active optical cable, it delivers lower power consumption per bit and better thermal behavior than many passive copper assemblies. The QSFP28 male connector format enables compatibility with common 100 Gigabit and InfiniBand QSFP28 ports, while the 50 m length allows flexible rack-to-rack or row-to-row routing without additional transceivers. The optical design reduces crosstalk and susceptibility to electromagnetic interference, contributing to stable operation in densely cabled installations.
Suitable for
 High-performance computing clusters requiring low-latency interconnects
 Data center uplinks between servers, switches and storage nodes
 Network fabrics using InfiniBand or QSFP28-compatible ports
 Rack-to-rack or row-to-row cabling where a 50 m reach is needed
Key specifications
 Cable type: Active optical cable (AOC)
 Connector type: QSFP28 male on both ends
 Length: 50 metres
 Supported interface: InfiniBand and QSFP28-compatible high-speed links
 Signal medium: Optical fibre with integrated transceivers
 EMI immunity: Higher resistance to electromagnetic interference than copper
How to use
Install the BlueOptics QSFP28 male connectors into QSFP28 ports on compatible switches, servers or adapters. Ensure devices are powered down or support hot-plugging per manufacturer guidance before insertion or removal. Route the 50 m cable to avoid sharp bends and excessive tension, maintaining the manufacturer’s minimum bend radius and securing the cable to prevent strain on connectors. Verify link negotiation and status indicators on connected equipment to confirm a successful connection and proper speed/duplex settings where applicable.
Usage recommendations
Use the cable in temperature- and dust-controlled data center environments; avoid exposure to liquids, compressive loads or tight cable bundles that can impair airflow. For optimal performance, pair the AOC with compatible QSFP28 ports and ensure firmware and driver support for InfiniBand or 100GbE operation as required by your network equipment.
