BlueOptics Q28-AOC-7M-SS-BO καλώδιο οπτικών ινών InfiniBand 7 m QSFP28

The BlueOptics Q28-AOC-7M-SS-BO InfiniBand fibre optic cable is a 7-metre QSFP28 to QSFP28 active optical cable (AOC) designed for short-reach, high-speed connections in data centres and high-performance computing environments. Built with OM3 multimode fibre (50 µm core) and LSZH flame-resistant sheathing, this AOC supports 100GBASE-SR4 Ethernet applications and provides a lightweight, flexible alternative to direct attach twinax solutions. Each cable integrates electrical-to-optical and optical-to-electrical conversion within the QSFP28 transceiver housings and is manufactured to SFF/MSA and IEEE specifications.

Advantages

The BlueOptics QSFP28 AOC delivers high throughput with low latency over short distances while remaining hot-pluggable and lighter than equivalent DAC assemblies. The OM3 multimode fibre and built-in transceiver converters reduce signal loss and simplify connectivity between rack-mounted devices. The LSZH jacket reduces halogen emission and smoke in case of fire, supporting safer installations in enclosed spaces. Each unit is factory-new and tested for compliance with industry standards such as CE and RoHS.

Suitable for

• 100GBASE-SR4 Ethernet links inside single racks or between adjacent racks
• InfiniBand high-performance computing interconnects
• Connections between QSFP28 ports on switches, routers, servers, and NICs
• Data centre top-of-rack and short aggregation cabling

Key specifications

• Cable type: Active Optical Cable (AOC), QSFP28 to QSFP28
• Length: 7 metres
• Fibre type: OM3 multimode
• Core diameter: 50 µm
• Application: 100GBASE-SR4 Ethernet / InfiniBand short-reach
• Sheath: LSZH (low smoke, zero halogen) flame-resistant jacket
• Hot-pluggable transceiver housings with embedded electrical–optical conversion
• Compliant with SFF/MSA and relevant IEEE interface specifications

How to use

Plug the QSFP28 connector into compatible QSFP28 ports on network switches, servers or host adapters, ensuring correct orientation and secure latch engagement. The active optical cable requires no separate transceivers or fibre termination; the conversion electronics are integrated in the QSFP28 housings. For initial deployment, verify link status indicators on connected equipment and confirm link speed and lane configuration in device management interfaces.

Recommendations

Route and secure the AOC to avoid sharp bends and excessive tensile stress; adhere to the manufacturer's minimum bend radius for multimode optical cables. Use LSZH-sheathed cables in enclosed or public spaces where low smoke and halogen-free properties are required. Prior to installation, inspect connectors for contamination and, if needed, clean with appropriate fibre-cleaning tools to maintain signal integrity.
