## Summary description

The BlueOptics Q28-AOC-3M-SO-BO is a 3-meter InfiniBand/fibre optic cable featuring QSFP28 connectors. It offers high-speed data transfer and reliable connectivity for data centers and high-performance computing environments.

## Long description

The BlueOptics Q28-AOC-3M-SO-BO InfiniBand/fibre optic cable 3m QSFP28 Male/Male is a 3‑metre active optical cable designed for high-density, high-throughput network environments. It connects QSFP28 ports on switches, servers and adapters to deliver low-latency, high-bandwidth links suitable for 100 Gigabit Ethernet and InfiniBand HDR environments. The cable assembly combines QSFP28 male connectors on both ends with an optical active link to minimize electrical interference and support reliable data transmission over a 3 m span.
Advantages
This QSFP28 active optical cable provides high data rates and low power consumption compared with equivalent copper assemblies. Its optical design reduces susceptibility to electromagnetic interference and crosstalk, while the fixed 3 m length simplifies cable management in racks and enclosures. The cable supports long-term stable performance for continuous data centre operations and is compatible with equipment that accepts QSFP28 form-factor modules.
Suitable for
Interconnecting QSFP28 ports in data centre switches and routers
Linking high-performance computing nodes in InfiniBand clusters
Direct server-to-switch connections requiring 100 Gbit/s or equivalent throughput
Short-range optical links within server racks and network cabinets
Key specifications
Cable type: Active Optical Cable (AOC)
Connector type: QSFP28 male to QSFP28 male
Length: 3 metres
Supported protocols: 100 Gigabit Ethernet, InfiniBand (HDR/EDR rates depending on system compatibility)
Transmission medium: Multi-channel optical fibre within AOC assembly
Typical latency: Low, suitable for low-latency network requirements
Operating environment: Data centre and server room use
How to use
Install the cable by aligning each QSFP28 male connector with the corresponding QSFP28 port until the connector latches or seats securely; do not force the plug. Verify that connected devices recognise the link and negotiate the expected speed and link parameters. Route the 3 m cable to avoid tight bends and excessive tension; maintain the minimum bend radius specified by the device manufacturer. For hot-pluggable systems, insert or remove the cable with the host and peer devices powered on only if the equipment supports hot-swap operations.
Usage recommendations
Handle connectors by their housing and keep connector ends protected from dust. Avoid kinking the cable and maintain proper rack management to prevent strain. Confirm compatibility with your switch or adapter vendor for supported link modes and firmware interoperability before deployment.
