BlueOptics XXVAOCBL30M-BO InfiniBand fibre optic cable 30 m SFP28

The BlueOptics XXVAOCBL30M-BO InfiniBand fibre optic cable 30 m SFP28 is a 30‑metre active optical cable (AOC) with SFP28 connectors on both ends designed for 25G data links over short-range multimode fibre. It integrates transceivers and multimode optical link components to transmit and receive signals simultaneously, supporting high-speed Ethernet and Fibre Channel over Ethernet applications up to 25 Gbit/s across a 30 m link. The cable follows SFP28 AOC MSA mechanical and electrical conventions to ensure physical fit and interoperable behaviour with systems that support SFP28 AOCs.

Advantages

This 30 m AOC provides a factory-terminated fibre solution that eliminates the need for patch cords and manual polishing, reducing insertion loss and simplifying rack-to-rack interconnects. Digital diagnostics (DDM/DOM) support enables remote monitoring of key parameters such as supply voltage, laser bias current, transmit power, receive power and temperature when the host hardware exposes the interface. The pre-integrated design reduces susceptibility to electromagnetic interference and offers predictable latency and consistent bandwidth over the specified distance.

Suitable for

• Data centre top-of-rack and rack-to-rack interconnects
• High-performance computing clusters and InfiniBand links
• Switch-to-switch and switch-to-storage connections supporting 25G
• Short-range multimode fibre installations requiring SFP28 interfaces

Key specifications

• Connector type: SFP28 to SFP28, male
• Length: 30 metres
• Data rate support: up to 25 Gbit/s
• Media: multimode fibre (active optical cable)
• DDM/DOM support for real-time diagnostics (subject to host support)
• Complies with SFP28 AOC MSA electrical and mechanical conventions

How to use

Insert the SFP28 plugs into the corresponding SFP28 ports of the devices to be connected and ensure each module latches securely. Verify that the host devices support SFP28 AOC modules and that any required firmware settings permit the DDM/DOM interface if diagnostics are required. After installation, confirm link establishment and correct data rate negotiation in the host operating system or switch management interface. Avoid sharp bends in the pre‑assembled cable and route it following standard cable‑management practices to prevent mechanical stress.

Usage recommendations

Handle the active optical cable by the connector housings, keep connector endfaces free of dust, and route the cable with gentle curves greater than the manufacturer’s minimum bend radius. Ensure the host equipment supports SFP28 AOCs and DDM/DOM if monitoring is needed. For mixed-vendor environments, verify interoperability in a controlled test before deployment.
