Καλώδιο InfiniBand/οπτικής ίνας BlueOptics Q28-AOC-7M-IB-BO 7m OM3

The BlueOptics Q28-AOC-7M-IB-BO is a 7 m Active Optical Cable (AOC) with QSFP28 to QSFP28 connectors and OM3 multimode fibre designed for InfiniBand and 100GBASE-SR4 Ethernet environments. It converts electrical signals to optical and back on the plug level, enabling reliable high-speed data transmission between devices within racks or between adjacent racks. The cable features a low-smoke, halogen-free (LSZH) sheath, a reduced bend radius and lower weight compared to direct attach twinax solutions, making it suitable for dense cabling runs in data centres and high-performance computing installations.

Advantages

The AOC provides high bandwidth for short-range high-speed links while remaining hot-pluggable and more flexible than equivalent DAC solutions. Integrated I/O and O/E converters in the QSFP28 plugs ensure signal integrity across the 7 m link. The OM3 multimode fibre and QSFP28 MSA-compliant connector design deliver consistent 100G performance, and the flame-retardant LSZH jacket reduces smoke and halogen release in the event of fire. Each cable is factory-new and tested to meet industry standards for functionality and build quality.

Suitable for

• Interconnects inside server racks or between adjacent racks
• 100GBASE-SR4 Ethernet links
• InfiniBand high-performance computing connections
• Data centre top-of-rack and aggregation layer cabling

Key specifications

• Cable length: 7 m
• Connector type: QSFP28 to QSFP28
• Fibre type: OM3 multimode
• Designed data rate: up to 100 Gbps (100GBASE-SR4 / QSFP28)
• Sheath: LSZH (low smoke, halogen-free)
• Active Optical Cable with integrated optical/electrical conversion
• Hot-pluggable design

How to use

Insert the QSFP28 connector into compatible QSFP28 ports on network switches, adapters or host devices, ensuring correct orientation and a secure latch. The cable is hot-pluggable, so it can be connected or disconnected while equipment is powered, following your hardware vendor’s guidelines. Route the cable with attention to its bend radius and avoid sharp bends or crushing; the OM3 multimode fibre and LSZH jacket tolerate typical rack routing but require reasonable handling to preserve optical performance. No external transceivers are required, as the electrical/optical conversion is integrated in the cable ends.

Recommendations

For optimal performance, use the BlueOptics Q28-AOC-7M-IB-BO for short-distance 100 Gbps links within a rack or between adjacent racks. Follow equipment manufacturer port compatibility lists and observe minimum bend radius and strain-relief practices. Store and install the cable in environments within the operating temperature and humidity ranges specified by your hardware vendor and avoid exposure to direct mechanical stress.
