BlueOptics Q28-AOC-2M-PS-BO InfiniBand fibre optic cable 2m QSFP28 Male

The BlueOptics Q28-AOC-2M-PS-BO InfiniBand fibre optic cable 2m QSFP28 Male is a 2-metre active optical cable (AOC) with QSFP28 connectors engineered for high-speed, short-reach interconnects. Designed according to MSA QSFP28 AOC standards, this cable supports 100GBASE-SR4 signaling over multimode fiber and integrates transmitter and receiver electronics in each connector to ensure correct optical signal transmission and protocol handling.

Advantages

The cable delivers high data throughput and low latency suitable for dense data centre and high-performance computing environments. Built to MSA specifications, it offers plug-and-play compatibility with equipment that supports QSFP28 AOC modules. Integrated digital diagnostics (DDM/DOM) provide real-time monitoring of supply voltage, laser bias current, transmit power, receive power and temperature, enabling remote maintenance and simplified troubleshooting. Components are selected to meet industrial quality standards, contributing to extended service life and high availability.

Suitable for

• Short-reach 100 Gbps links between switches, routers and storage arrays
• High-performance computing (HPC) clusters and InfiniBand fabric interconnects
• Data centre top-of-rack and spine connectivity where QSFP28 is supported
• Environments requiring electromagnetic immunity and reduced cabling attenuation

Key specifications

• Connector type: QSFP28 to QSFP28 (male)
• Length: 2 metres
• Data rate: up to 100 Gbps (100GBASE-SR4 compatible)
• Optical type: Active Optical Cable with multimode fiber
• Monitoring: Digital Diagnostics Monitoring / Digital Optical Monitoring (DDM/DOM) compliant with SFF-8472
• Compliance: Designed to MSA QSFP28 AOC mechanical and electrical specifications

How to use

Install the BlueOptics QSFP28 AOC by inserting each QSFP28 connector into the corresponding QSFP28 port on your devices until the latch engages. Ensure both endpoints support QSFP28 AOC modules and the 100GBASE-SR4 transmission profile. Check that the host equipment supports DDM/DOM if you need remote diagnostics. No additional transceivers or patching with separate fiber cables are required; the pre-assembled AOC provides a single, factory-terminated link.

Recommendations

Use the cable within recommended operating temperature ranges and avoid tight bends or excessive pulling to preserve optical integrity. When integrating into racks, route the cable to avoid mechanical stress and ensure proper strain relief. Verify firmware or hardware compatibility with the target platform where required and, if possible, validate with a short test deployment to confirm link parameters and DDM readings before large-scale roll-out.
