BlueOptics Q28-AOC-3M-CP-BO InfiniBand/optický kabel 3 m QSFP28 samec/samec

The BlueOptics Q28-AOC-3M-CP-BO InfiniBand/fibre optic cable 3m QSFP28 Male/Male is a 3-meter active optical cable designed for high-speed data transmission in data centers and high-performance computing environments. With QSFP28 connectors on both ends, this cable supports high-bandwidth links while providing a compact, low-latency physical connection between compatible networking devices. Its plug-and-play male-to-male configuration simplifies integration with switches, servers and network adapters that accept QSFP28 interfaces.

Advantages

This 3 m active optical cable offers the benefits of optical signalling — reduced electromagnetic interference and stable signal integrity over short to medium distances — while maintaining the mechanical convenience of direct-attach cabling. The QSFP28 interfaces deliver compatibility with 100 Gigabit-class InfiniBand and Ethernet implementations where QSFP28 ports are supported. The cable’s flexible construction and fixed length reduce installation complexity and help maintain predictable link performance.

Suitable for

• Interconnecting QSFP28-equipped switches and routers in data center racks
• Direct links between servers and network adapters with QSFP28 ports
• High-performance computing clusters requiring low-latency, high-bandwidth links
• Short-reach backbone connections inside equipment cabinets and rack rows

Key specifications

• Cable type: Active optical cable (AOC)
• Connector type: QSFP28 male to QSFP28 male
• Length: 3 meters
• Supported link class: InfiniBand and high-speed Ethernet (QSFP28/100G-class)
• Signal medium: Fibre optic (optical transceivers integrated in the cable assembly)
• Typical applications: Data center interconnects, server-to-switch links, HPC fabrics

How to use

Ensure both devices have compatible QSFP28 ports and are powered down or in a hot-pluggable state according to the equipment vendor’s instructions. Align the QSFP28 plugs with the port guides and insert each end until it seats firmly; secure latching mechanisms if present. After installation, verify link status through the connected devices’ management interfaces and confirm that negotiated speed and lane configuration match your network requirements. For removal, disengage any retention features and pull straight out along the connector axis to avoid stressing the cable.

Recommendations

Handle the cable by the connector housings and avoid tight bends; follow the manufacturer’s minimum bend radius guidelines. Use this 3 m AOC for intra-rack and short inter-rack connections where QSFP28 interfaces are supported. Check device compatibility and firmware/OS release notes to ensure proper link negotiation and feature support.
