BlueOptics Q28-AOC-7M-IT-BO InfiniBand fibre optic cable 7m QSFP28 Aqua

The BlueOptics Q28-AOC-7M-IT-BO InfiniBand fibre optic cable is a 7 m QSFP28-to-QSFP28 Active Optical Cable (AOC) designed for short-distance, high-speed connections inside and between server racks. It uses OM3 multimode fibre with a 50 µm core diameter and supports 100GBASE-SR4 Ethernet and InfiniBand high-throughput links. The cable features hot-pluggable QSFP28 transceiver-style connectors with integrated electrical-to-optical and optical-to-electrical conversion and an LSZH (low smoke zero halogen) flame-resistant sheath for safer installation in data center environments.

Advantages

Compared with passive twinax Direct Attach solutions, this Active Optical Cable offers reduced weight, greater flexibility, and a smaller bend radius while maintaining high data-rate performance. The QSFP28 connectors conform to common MSA, SFF and IEEE specifications, ensuring interoperability with compatible ports. Each unit is factory new and tested for quality and functionality; components from established manufacturers are used and production follows applicable industry standards for safety and electromagnetic compatibility.

Suitable for

• Short-reach 100 Gbps connections within a rack or between adjacent racks
• InfiniBand and 100GBASE-SR4 Ethernet high-performance networking
• Data center server-to-switch or switch-to-switch links requiring QSFP28 ports
• Environments where low smoke and halogen-free cabling is required

Key specifications

• Length: 7 metres
• Connector type: QSFP28 to QSFP28 (active optical)
• Fibre type: OM3 multimode
• Core diameter: 50 µm
• Supported standard: 100GBASE-SR4 Ethernet / InfiniBand compatible
• Sheath material: LSZH (low smoke zero halogen), flame resistant
• Hot-pluggable transceiver-style connectors with integrated O/E and E/O conversion

How to use

Insert each QSFP28 connector into compatible QSFP28 ports on network equipment until the connector latches. The integrated transceiver modules handle signal conversion automatically; no separate optics or configuration is required on the cable itself. Route the cable avoiding tight bends and secure it along rack infrastructure using appropriate cable management to maintain the recommended bend radius. Before deployment, verify link status on connected devices and confirm expected link speeds and lane configuration in the host hardware.

Usage recommendations

Use this 7 m BlueOptics QSFP28 AOC for short-range high-bandwidth interconnects inside racks or between adjacent racks. Prefer OM3-rated patching paths and maintain proper bend radius. Avoid exposure to sharp edges and excessive torsion; store and handle the cable according to vendor guidance. For compliance and interoperability, pair the cable with QSFP28-capable equipment that supports 100GBASE-SR4 or compatible InfiniBand standards.
