BlueOptics Q28-AOC-7M-QN-BO cavo in fibra ottica InfiniBand 7m OM3

The BlueOptics Q28-AOC-7M-QN-BO InfiniBand fibre optic cable 7m OM3 is an active optical cable (AOC) with QSFP28 connectors on both ends. Designed for short-reach, high-speed connections within or between adjacent server racks, this 7 metre OM3 variant supports 100GBASE-SR4 Ethernet and InfiniBand links. The cable includes built-in electrical-to-optical and optical-to-electrical conversion modules in the QSFP28 housings and is sheathed in flame-resistant LSZH material to limit smoke and halogen emissions.

Advantages

This BlueOptics QSFP28 to QSFP28 AOC provides reduced weight and increased flexibility compared with comparable direct-attach twinax solutions. The integrated transceivers comply with common MSA, SFF and IEEE specifications and offer a small bend radius and compact diameter for easier cable routing in dense rack environments. Each unit is factory new, tested for functionality and manufactured using high-quality components to meet CE and RoHS requirements.

Suitable for

• High-performance computing clusters requiring InfiniBand or 100G Ethernet interconnects
• Data centre top-of-rack and adjacent-rack connections
• Switch-to-switch or switch-to-server 100G links over short distances
• Environments where reduced cable weight and improved flexibility are needed

Key specifications

• Cable type: Active Optical Cable (AOC)
• Length: 7 metres
• Connector type: QSFP28 to QSFP28 (hot-pluggable)
• Fibre type: OM3 multimode
• Application: 100GBASE-SR4 Ethernet / InfiniBand high-speed links
• Sheath: LSZH (low smoke zero halogen), flame resistant
• Compliance: Manufactured and tested to common MSA, SFF and IEEE industry standards; RoHS and CE compliant

How to use

Install the BlueOptics QSFP28 to QSFP28 AOC by inserting the QSFP28 connector into compatible QSFP28 ports on network switches, servers or adapters. The cable is hot-pluggable; ensure the host devices are configured for 100G Ethernet or InfiniBand operation and that link settings match at both ends. Route the cable to avoid sharp bends and keep within recommended bend radius. No external power is required for the cable beyond the powered QSFP28 ports on the connected devices.

Recommendations

Handle the cable by the connector housings and avoid applying strain to the fibre assembly. Maintain a bend radius appropriate for OM3 multimode AOC assemblies, keep the LSZH sheath clean, and verify link status after installation. Use this 7 m OM3 AOC for short-reach, high-bandwidth interconnects inside racks or between adjacent racks; for longer distances consider appropriate transceivers and fibre cabling types.
