BlueOptics Q28-AOC-3M-PS-BO InfiniBand Fibre Optic Cable 3m QSFP28 Male

The BlueOptics Q28-AOC-3M-PS-BO InfiniBand Fibre Optic Cable 3m QSFP28 Male is a 3‑meter active optical cable (AOC) with QSFP28 connectors at both ends designed for 100G high‑speed links. It implements the QSFP28 AOC MSA interface and supports multimode optical transmission for applications such as Ethernet, Fibre Channel over Ethernet and SDH/SONET. The cable integrates transmitters and receivers in the plug assemblies and offers a pre‑terminated, factory‑tested connection that eliminates the need for field splicing or patchcord cleaning.

Advantages

This 3 m BlueOptics AOC provides native QSFP28 to QSFP28 connectivity with support for 100GBASE‑SR4 class transmission, delivering low latency and immunity to electromagnetic interference. Factory testing and MSA compliance ensure interoperability with equipment that supports QSFP28 AOCs. Built with components from established optics suppliers and digital diagnostic monitoring (DDM/DOM) support, the cable is designed for long operational lifetime and simplified remote diagnostics.

Suitable for

• High‑performance computing clusters and InfiniBand fabrics
• Data center top‑of‑rack and spine switch interconnects
• Storage arrays and SAN connectivity supporting 100G links
• Low‑latency trading or compute environments requiring fiber links

Key specifications

• Length: 3 meters
• Connector type: QSFP28 to QSFP28 (male/male)
• Maximum data rate: 100 Gbit/s (100GBASE‑SR4 compatible)
• Transmission medium: multimode fiber (active optical cable)
• MSA compliance: QSFP28 AOC standard
• Digital diagnostics: DDM / DOM (MSA SFF‑8472 compliant)
• Typical application protocols: Ethernet, Fibre Channel over Ethernet, SDH/SONET

How to use

Install the BlueOptics Q28‑AOC‑3M‑PS‑BO by inserting each QSFP28 plug into the corresponding QSFP28 port on your devices while both ends are powered off or per your device vendor’s hot‑plug guidelines. Ensure ports are compatible with QSFP28 AOCs and that the host hardware supports the DDM/DOM interface if diagnostics are required. Avoid bending the cable beyond manufacturer bend radii and secure the cable to prevent strain on the connectors. After connection, verify link status and operational parameters via the host equipment management interface or the DDM/DOM readings.

Recommendations

For reliable long‑term operation, route the cable away from sharp edges and high‑traffic areas, respect the minimum bend radius, and confirm firmware and hardware compatibility with QSFP28 AOC modules. Use DDM/DOM information for proactive monitoring and troubleshooting when supported by your equipment.
