## Summary description

The BlueOptics Q28-AOC-3M-AO-BO is a 3-meter InfiniBand/fibre optic cable featuring QSFP28 connectors. It is designed for high-speed data transmission between devices, ensuring reliable performance and minimal latency. This cable is ideal for data centers and high-performance computing environments, providing a robust solution for connecting network equipment.

## Long description

The BlueOptics Q28-AOC-3M-AO-BO InfiniBand/fibre optic cable 3m QSFP28 Male/Male is a 3-metre active optical cable designed for high-speed, low-latency connections between QSFP28 ports. Intended for use in data centre and high-performance computing environments, this cable provides a compact, energy-efficient alternative to copper cables while maintaining signal integrity over a short to medium reach. Its QSFP28 male connectors are compatible with QSFP28 interfaces and support the data throughput expected in 100 Gigabit-class links and InfiniBand HDR/EDR-compatible systems.
Advantages
The cable delivers high bandwidth with reduced electromagnetic interference and lower heat generation compared with equivalent copper assemblies. As an active optical cable, it integrates transceivers and optical fibres in a single assembly, simplifying installation and reducing the number of separate modules required. Its 3-metre length balances reach and signal performance for rack-to-rack or top-of-rack connections, and QSFP28 connectivity enables dense port deployment in modern network switches and servers.
Suitable for
Rack-to-rack connections in data centres
Top-of-rack to switch links
High-performance computing clusters using InfiniBand or 100GbE interfaces
Short- to medium-reach links where low latency is required
Key specifications
Connector type: QSFP28 Male to QSFP28 Male
Length: 3 metres
Cable type: Active optical cable (AOC)
Supported interfaces: InfiniBand and 100 Gigabit Ethernet-class QSFP28
Typical use: Short- to medium-reach high-speed data links
How to use
Ensure both devices have compatible QSFP28 ports and are powered down or in a safe state for hot-plugging according to the equipment manufacturer’s guidelines. Align the QSFP28 male connector with the port and insert firmly until the latch engages. After connection, verify link status on the connected devices and confirm negotiated link speed and lane configuration. For removal, release the connector latch and pull straight out to avoid stress on the port and cable.
Usage recommendations
Route the cable with gentle bends, avoiding tight radii and crushing. Maintain proper ventilation around active components, and follow equipment vendor guidance for hot-plug procedures and supported cable types. For critical links, verify compatibility with switch or server documentation and test link performance after installation.
