## Long description

The BlueOptics Q28-AOC-3M-NK-BO InfiniBand fibre optic cable 3m QSFP28 Male/Male is a 3-meter active optical cable engineered for high-speed, low-latency connections in data centres and high-performance computing clusters. It features QSFP28 male connectors on both ends and supports the bandwidth and signalling required for InfiniBand interconnects, providing a compact, plug-and-play alternative to discrete transceivers and separate fibre patch cords.
Advantages
This QSFP28 active optical cable offers high data throughput with reduced electromagnetic interference and low power consumption compared with equivalent copper solutions. The fixed-length 3 m design simplifies rack planning and cable management while preserving signal integrity over short to medium distances. QSFP28 male-to-male terminations enable straightforward installation into compatible QSFP28 ports without additional transceiver modules.
Suitable for
Connecting switches, routers and host adapters in data centres
High-performance computing (HPC) cluster interconnects
Server-to-switch or switch-to-switch links in rack environments
Environments requiring low-latency, high-bandwidth links
Key specifications
Connector type: QSFP28 male to QSFP28 male
Length: 3 metres
Cable type: Active optical cable (AOC)
Supported interface: InfiniBand-compatible signalling and bandwidth
Typical application: Data centre and HPC interconnects
Physical form factor: Compact QSFP28 assembly for direct port connection
How to use
Ensure both devices have compatible QSFP28 ports and that firmware or driver requirements for InfiniBand links are met. Insert each QSFP28 connector firmly into the corresponding port until the latch engages. Cable routing should avoid tight bends and sharp edges; observe the manufacturer’s minimum bend radius for optical cables. For link configuration, follow system-specific procedures to enable and verify InfiniBand connectivity and check link status indicators on connected devices after installation.
Usage recommendations
Install the cable in cooled, dust-controlled racks and secure it to prevent strain on connectors. Use the 3 m length to maintain tidy cable runs within the rack or between adjacent racks; avoid excessive bending or kinking. For compatibility questions, consult device documentation for supported QSFP28 AOC links and verify that firmware and driver levels are current.
