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

The BlueOptics Q28-AOC-2M-AT-BO is a 2-meter active optical cable (AOC) with QSFP28 male connectors at both ends, designed for 100G data links in InfiniBand and Ethernet environments. The pre-terminated multi-mode fibre assembly integrates transmitter and receiver modules on each end and conforms to QSFP28 MSA electrical and mechanical specifications. This AOC supports 100GBASE-SR4 applications and provides a compact, plug-and-play connection between switches, routers, storage systems and other high-performance network devices over a 2 m distance.

Advantages

This BlueOptics QSFP28 AOC delivers high-speed optical transmission up to 100 Gbit/s while avoiding the need to terminate or patch fibre on-site. The integrated transceivers reduce connector loss and EMI susceptibility compared with copper alternatives. The cable is manufactured to MSA guidelines and uses quality optical and electronic components to provide consistent optical performance, digital diagnostics monitoring support and extended operating life suitable for data centre and HPC deployments.

Suitable for

• 100G interconnects between QSFP28 ports in switches and routers
• High-performance computing clusters and InfiniBand links
• Storage area network (SAN) and Fibre Channel over Ethernet uplinks
• Short-reach data centre cross-connects (2 m)

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Nominal data rate: up to 100 Gbit/s (100GBASE-SR4 compatible)
• Cable length: 2 metres
• Fibre type: multi-mode (active optical cable with integrated transceivers)
• Form factor compliance: QSFP28 MSA
• Monitoring: Digital Diagnostics (DDM/DOM) support
• EMI immunity: inherent to fibre optic transmission

How to use

Insert each QSFP28 connector into matching QSFP28 ports on the equipment until the latch engages. Verify that both ends are fully seated and that host devices recognise the AOC; check link status and speed via the network equipment management interface. Use the host’s diagnostics interface to read DDM/DOM parameters if supported. Avoid sharp bends and excessive pulling on the cable; maintain the manufacturer-recommended bend radius for multi-mode AOCs to preserve optical performance.

Recommendations

For reliable operation, ensure compatibility with the target hardware and firmware versions, confirm that QSFP28 ports support 100GBASE-SR4 or equivalent AOC modules, and verify DDM/DOM availability if monitoring is required. Store and route the cable to prevent tight bends or crushing and follow standard data centre fibre handling procedures to maximise lifetime and signal integrity.
