BlueOptics MFA1A00-E025-BO InfiniBand fibre optic cable 25 m QSFP28

The BlueOptics MFA1A00-E025-BO InfiniBand fibre optic cable 25 m QSFP28 is a 25-metre active optical cable (AOC) with QSFP28 male connectors on both ends designed for high-speed server and data centre interconnects. Built to MSA-compatible QSFP28 form factors, this multimode fibre AOC integrates transmitters and receivers in the transceivers to carry 100G-class signals over a 25 m link. The cable supports standard 100GBASE-SR4 and related InfiniBand and Ethernet protocols, providing deterministic performance for switch-to-switch, switch-to-server and storage system connections.

Advantages

This AOC delivers low-latency, high-bandwidth connectivity and eliminates the need for separate transceivers and patch cables, simplifying rack cabling and reducing insertion points. The integrated optical transceivers ensure signal integrity over the specified distance while maintaining compliance with QSFP28 MSA electrical and mechanical requirements. The cable's fixed length and QSFP28 interfaces provide a plug-and-play experience with supported hardware, enabling consistent 100G performance for data centre fabrics and high-performance computing clusters.

Suitable for

• 100G switch-to-switch connections in data centres
• High-performance computing (HPC) clusters using InfiniBand or Ethernet fabrics
• Connections between switches, routers and storage systems requiring a 25 m reach
• Short-run server-to-top-of-rack or server-to-switch links in structured cabling

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Cable type: Active Optical Cable (AOC) with multimode fibre
• Supported data rates: up to 100 Gbit/s
• Standard compatibility: 100GBASE-SR4 and InfiniBand-compatible QSFP28 form factor
• Length: 25 metres
• Integrated transmitters and receivers on both ends for optical signalling
• Application environment: data centre and networking racks

How to use

Power off or follow hot-plug procedures recommended by your hardware vendor before connecting. Align and insert the QSFP28 connectors into compatible QSFP28 ports on switches, routers or servers until they seat fully. Verify link status through the host device management interfaces and ensure firmware and driver compatibility for 100G operation. Use the cable as a fixed 25 m link; do not attempt to splice or modify the fibre elements. When removing, depress any retention latch and gently withdraw to avoid damaging the connector or port.

Recommendations

Install the cable free of sharp bends and maintain the minimum bend radius specified by the manufacturer. Use this AOC in hardware that explicitly supports QSFP28 AOCs and 100GBASE-SR4 or compatible InfiniBand profiles to ensure interoperability. For mixed-vendor environments, confirm compatibility with device firmware and test links before deploying in production.
