## Summary description

The BlueOptics Q28-AOC-50M-CN-BO is a 50m InfiniBand fibre optic cable featuring QSFP28 connectors. It provides high-speed data transmission and is ideal for data centers and high-performance computing environments.

## Long description

The BlueOptics Q28-AOC-50M-CN-BO InfiniBand fibre optic cable 50m QSFP28 Male/Male is a 50-metre active optical cable designed for high-speed interconnects. It uses QSFP28 form-factor connectors on both ends to support InfiniBand and Ethernet-compatible links at high data rates. The cable is intended for direct attachment between switches, servers and storage devices in data centres and high-performance computing clusters where low latency and reliable throughput are required.
Advantages
This QSFP28 AOC delivers high aggregate bandwidth over a single assembly while avoiding electrical signal degradation typical of long copper links. At 50 metres, the cable offers flexibility in equipment placement and rack layout without the need for transceivers and separate fibre patching. The integrated optical design reduces power consumption and heat compared with active electrical cables, and the standardized QSFP28 connectors ensure compatibility with equipment that supports InfiniBand and corresponding high-speed Ethernet interfaces.
Suitable for
Interconnecting QSFP28-capable switches and directors in data centres
Direct server-to-switch or server-to-storage links in HPC environments
Low-latency fabric connections for cluster computing and AI workloads
Cable runs where 50 m reach is required without intermediate transceivers
Key specifications
Cable type: Active optical cable (AOC)
Connector type: QSFP28 male to QSFP28 male
Length: 50 metres
Supported interfaces: InfiniBand and high-speed Ethernet-compatible QSFP28 links
Data rate: Designed for 100 Gbps-class QSFP28 links (aggregate multi-lane speeds)
Construction: Integrated optical transceivers with ruggedized jacket for data centre use
Latency: Low optical latency suitable for HPC and low-latency fabrics
How to use
Install the BlueOptics QSFP28 AOC by aligning each QSFP28 male connector with the compatible QSFP28 port on your switch, server or storage device and gently insert until the latch engages. No separate transceivers or patch fibres are required; the integrated transceiver modules are pre-terminated. When removing, release the connector latch and extract straight out to avoid stressing the cable. Ensure ports at both ends are powered and configured to support the intended link speed and protocol (InfiniBand or compatible Ethernet) according to your equipment documentation.
Usage recommendations
Route the cable to avoid tight bends and sharp edges; observe the minimum bend radius specified by the manufacturer. Use cable management trays or ties to secure runs and maintain airflow in the rack. Verify firmware and port settings on connected devices to ensure link negotiation at expected speeds. For long-term reliability, keep connectors covered when not in use and inspect the cable for damage before installation.
