BlueOptics AOC-Q28-100G-7M-BO InfiniBand fibre optic cable 7m QSFP28 Male/Male

The BlueOptics AOC-Q28-100G-7M-BO InfiniBand fibre optic cable is a 7-metre active optical cable with QSFP28 male connectors on both ends. Designed for high-speed data transmission, this cable implements the 100GBASE-SR4 signaling profile over multimode fiber and is intended for short-reach, high-throughput links in data centres and high-performance computing environments. The AOC contains integrated transmitter and receiver modules at each end, providing a factory-assembled optical link that removes the need for separate transceivers and patch cords.

Advantages

The cable provides a compact, plug-and-play solution for establishing 100 Gbps links between QSFP28 ports while maintaining compliance with common MSA connector and signalling conventions. As an active optical cable, it offers electrical isolation and reduced weight compared with equivalent copper direct-attach assemblies, and supports multimode optical transmission for predictable short-reach performance over a 7 metre distance.

Suitable for

• Interconnects between switches, routers and storage systems with QSFP28 ports
• High-performance computing clusters requiring low-latency 100 Gbps links
• Data centre top-of-rack and spine connections over short distances
• Environments where integrated AOC modules simplify cabling and reduce component count

Key specifications

• Cable type: Active optical cable (AOC)
• Connector type: QSFP28 male to QSFP28 male
• Rated data rate: 100 Gbps (100GBASE-SR4 compatible)
• Length: 7 metres
• Fiber type: Multimode optical fibre (multimode MPO-style interface internally)
• Applications supported: Ethernet, Fibre Channel over Ethernet, SDH/SONET high-speed transports

How to use

Insert each QSFP28 connector into corresponding QSFP28 ports on devices that support 100G AOC connections, ensuring proper orientation and secure seating. The integrated transmitters and receivers are pre-aligned; the cable will be recognised by compatible network and storage equipment as a single optical link. Verify port settings on connected devices (speed, protocol) and confirm link status indicators after insertion. When removing the cable, grip the connector body and pull straight out to avoid stress on the port.

Recommendations

Use this AOC for short-reach 100 Gbps connections within racks or between adjacent racks. Avoid sharp bends and excessive pulling force on the cable; maintain the manufacturer’s minimum bend radius. Confirm device compatibility with QSFP28 AOC modules and ensure firmware or platform support where vendor-specific compatibility is required.
