Cabo de fibra ótica InfiniBand BlueOptics Q28-AOC-3M-CN-BO 3m QSFP28 macho/macho

The BlueOptics Q28-AOC-3M-CN-BO InfiniBand fibre optic cable 3m QSFP28 Male/Male is a 3-metre active optical cable designed for high-speed, short-reach connections in data center and high-performance computing environments. With QSFP28 male connectors on both ends, this cable supports InfiniBand protocols and is intended to deliver reliable, low-latency data transmission between switches, servers and storage systems where high bandwidth and signal integrity are required.

Advantages

This QSFP28 active optical cable provides high bandwidth over a compact form factor while maintaining low power consumption and minimal signal degradation over the specified 3 m length. The plug-and-play male-to-male QSFP28 interfaces enable straightforward installation without additional transceivers. The optical construction reduces electromagnetic interference and supports stable, low-latency links suitable for clustered computing and storage networks.

Suitable for

• Connecting QSFP28 ports between switches and routers in data centers
• Direct connections between servers in high-performance computing clusters
• Linking storage arrays and host adapters requiring InfiniBand connectivity
• Short-reach interconnects within rack or between adjacent racks

Key specifications

• Cable type: Active optical cable (AOC)
• Connector type: QSFP28 male to QSFP28 male
• Length: 3 metres
• Supported interface: InfiniBand (QSFP28 form factor)
• Use case: Short-reach, high-bandwidth links
• Signal characteristics: Low latency, optical transmission to reduce EMI

How to use

Ensure both devices have compatible QSFP28 ports configured for InfiniBand operation. With devices powered down or in a hot-plug supported state, align the QSFP28 connector keying and insert each end into the respective ports until the retention mechanism engages. After connection, verify link status on the devices and confirm proper data transmission through management interfaces. For removal, disengage the retention latch and pull the connector straight out to avoid stressing the cable assemblies.

Recommendations

Use this 3 m QSFP28 AOC for short-distance links inside racks or between adjacent racks to maintain optimal signal quality. Avoid sharp bends beyond the cable minimum bend radius and keep the optical connectors free of dust; use protective caps when not connected. Confirm firmware and port configuration compatibility for InfiniBand to ensure stable operation.
