BlueOptics Q28-AOC-1M-PS-BO InfiniBand fibre optic cable 1m QSFP28

The BlueOptics Q28-AOC-1M-PS-BO InfiniBand fibre optic cable 1m QSFP28 is a 1‑metre active optical cable (AOC) with QSFP28 male connectors on both ends. Designed for 100GBASE‑SR4 class links, the cable integrates optical transmitters and receivers and conforms to QSFP28 MSA electrical and mechanical specifications for interoperable high‑speed connections in data centres and high‑performance computing environments.

Advantages

This QSFP28 to QSFP28 AOC provides a pre‑assembled multi‑mode fiber link that is immune to electromagnetic interference and reduces the need for patch cords and manual termination. The cable supports simultaneous send/receive optical transmission, includes digital diagnostics monitoring (DDM/DOM) for real‑time status reporting, and is manufactured using widely used components to achieve extended service life and high MTBF.

Suitable for

• High‑performance computing clusters and InfiniBand fabrics
• Data centre switch‑to‑switch or switch‑to‑server connections
• Storage systems and SAN interconnects supporting 100GBASE‑SR4
• Short‑reach optical links where QSFP28 direct attach is required

Key specifications

• Form factor: QSFP28 to QSFP28 active optical cable
• Length: 1 metre
• Rated data rate: up to 100 Gbps (100GBASE‑SR4 class)
• Transmission medium: multi‑mode fiber with integrated transmitters and receivers
• DDM/DOM support for voltage, temperature, laser bias, transmit/receive power monitoring
• MSA compliance for QSFP28 electrical and mechanical interfaces
• Designed for short‑reach intra‑rack and inter‑rack connections

How to use

Connect the QSFP28 plugs to QSFP28 ports on compatible switches, routers, servers or storage devices. Ensure ports are powered and support 100GBASE‑SR4 or the target protocol (Ethernet, FCoE or others). If available, enable or query the module’s DDM/DOM interface to monitor operating parameters. Route the cable without sharp bends and avoid kinking; follow equipment vendor guidelines for hot‑plugging and handling to prevent damage to transceivers and ports.

Recommendations

Verify hardware compatibility with QSFP28 AOC modules in your platform and confirm that the host supports DDM/DOM if monitoring is required. Install the cable in tidy, strain‑relieved runs, keep connectors clean, and avoid excessive bend radius to maintain link performance and longevity.
