BlueOptics Q28-AOC-7M-CN-BO Καλώδιο οπτικών ινών InfiniBand 7 m QSFP28

The BlueOptics Q28-AOC-7M-CN-BO InfiniBand fibre optic cable is a 7 metre active optical cable (AOC) with QSFP28 connectors on both ends and OM3 multimode fibre. Designed for short-range, high-speed interconnects in data centres and high-performance computing, this cable supports 100GBASE-SR4 Ethernet and provides converterized QSFP28 transceivers that transform electrical signals to optical and back for reliable 100 Gbit/s links between switches, servers and network appliances. The cable uses a 50 µm core diameter multimode fibre and a flame-retardant LSZH outer sheath to reduce smoke and halogen emission in case of fire.

Advantages

The active optical construction offers lower weight and greater flexibility compared with direct-attach twinax (DAC) solutions, together with a smaller bend radius and reduced cable diameter. QSFP28 transceiver modules are hot-pluggable and conform to SFF/MSA and IEEE conventions for interoperability. Each unit is factory-tested and supplied new, with components chosen from established manufacturers to support stable long-term operation and compliance with common industry safety and environmental norms.

Suitable for

• Short-range 100 Gbit/s connections within server racks or between adjacent racks
• High-performance computing cluster interconnects
• Top-of-rack or spine switch links requiring QSFP28 interfaces
• Environments where reduced weight and improved bend radius are needed

Key specifications

• Sheath: LSZH (low smoke, zero halogen), flame resistant
• Performance: designed for high-speed, short-reach transmission with small bend radius

How to use

Install the BlueOptics QSFP28 to QSFP28 AOC by inserting each QSFP28 connector into the corresponding QSFP28 port on the network devices until it latches. The integrated optical/electrical conversion is handled by the cable ends, so no additional transceivers are required. Verify link status through the host devices and ensure ports are configured for 100G operation as needed. To maintain signal integrity, avoid tight bends beyond the specified bend radius and route the cable inside racks or between adjacent racks for short-reach connections.

Recommendations

Handle the LSZH-sheathed AOC carefully during installation to avoid sharp bends and mechanical strain. Use cable management inside racks to prevent stress on connectors and maintain airflow. Confirm compatibility with device QSFP28 ports and verify that firmware or OS settings support 100GBASE-SR4 links.
