BlueOptics Q28-AOC-50M-PS-BO InfiniBand/fibre optic cable 50m QSFP28 Male/Male

The BlueOptics Q28-AOC-50M-PS-BO InfiniBand/fibre optic cable 50m QSFP28 Male/Male is a 50‑metre active optical cable (AOC) with QSFP28 connectors on both ends. Designed for 100GBASE‑SR4 and QSFP28 interfaces, the cable integrates transmitter and receiver modules and uses multimode fiber to support high‑speed data transmission in data centre, switch-to-switch and storage interconnect applications. The pre‑assembled AOC eliminates the need for separate transceivers and patch cords while reducing susceptibility to electromagnetic interference.

Advantages

The cable supports aggregated data rates up to 100 Gbit/s over 50 metres and follows QSFP28 MSA electrical and mechanical specifications for plug-and-play interoperability with compatible hardware. Integrated digital diagnostics (DDM/DOM) provide real‑time monitoring of supply voltage, laser bias current, transmit output power, received input power and temperature to aid remote troubleshooting. The Active Optical Cable design reduces inline attenuation and patching requirements, and the use of qualified optical and electronic components provides long operational lifetime and high availability.

Suitable for

• 100G switch-to-switch uplinks in data centres
• High‑performance storage system interconnects
• Aggregation links between routers and switches
• Short‑reach InfiniBand or Ethernet high‑speed links

Key specifications

• Cable length: 50 metres
• Connector type: QSFP28 male to QSFP28 male
• Supported protocol: 100GBASE‑SR4 (compatible with 100 Gbit/s multimode applications)
• Optical medium: multimode fiber with integrated optical transceivers
• Digital diagnostics: DDM/DOM (MSA SFF‑8472 compliant)
• MSA compliance: QSFP28 AOC mechanical/electrical compatibility
• Environmental / safety standards: CE and RoHS compliant

How to use

Install the BlueOptics QSFP28 AOC by inserting each QSFP28 connector into the corresponding QSFP28 port on supported switches, routers or storage devices while the host devices are powered on or per vendor guidance. Ensure the port configuration and firmware of connected hardware support QSFP28 AOCs and the 100GBASE‑SR4 profile. Access DDM/DOM readings through the host management interface or supported monitoring tools to verify operating parameters and link status. No separate transceivers, patch cords or fiber cleaning are required for the integrated AOC assembly.

Recommendations

Verify compatibility with your hardware vendor’s published list for QSFP28 AOCs and confirm that firmware and port settings support active optical cables and DDM/DOM features. Handle connectors by their housings, avoid sharp bends at the cable ends, and store the cable in a clean, dry environment to maintain performance and lifetime.
