InfiniBand/fibre optic cable BlueOptics MFA1A00-C030-BO 30 m QSFP28 Male/Male

The BlueOptics MFA1A00-C030-BO is a 30 m InfiniBand/fibre optic active optical cable (AOC) with QSFP28 male-to-male connectors designed for high-speed data transmission. Compatible with 100GBASE‑SR4 protocol and MSA QSFP28 interfaces, this cable integrates optical transmitters and receivers in the connector housings and uses multimode fiber to deliver reliable 100 Gbps links over a 30 metre distance. It is intended for data centers, high‑performance computing and networking environments that require low-latency, high-bandwidth interconnects between switches, routers, servers and storage systems.

Advantages

The AOC design eliminates separate transceivers and patch cords by combining optical electronics and fiber in a single QSFP28-to-QSFP28 assembly, reducing rack cabling complexity and power consumption compared with equivalent copper solutions. Support for 100GBASE‑SR4 ensures interoperability with MSA-compliant ports, while integrated transmitters and receivers provide stable signal integrity across the 30 m multimode link. The fixed-length cable simplifies deployment and management in structured cabling environments.

Suitable for

• 100 Gbps links between QSFP28 ports in data center switches and routers
• Interconnects for high-performance computing clusters and InfiniBand fabrics
• Server-to-switch and switch-to-switch connections within a 30 m rack or row
• Storage system connectivity and Fibre Channel over Ethernet (FCoE) applications

Key specifications

• Connector type: QSFP28 male-to-male
• Length: 30 metres (fixed)
• Data rate: up to 100 Gbps (100GBASE‑SR4)
• Fiber type: multimode fiber with integrated optical transceivers
• Compatibility: MSA-compliant QSFP28 ports supporting 100GBASE‑SR4 and related protocols
• Application protocols: Ethernet, Fibre Channel over Ethernet, SDH/SONET compatible at supported rates

How to use

Ensure both devices have QSFP28 ports that support 100GBASE‑SR4 or the intended 100G mode. With devices powered off or following hot‑swap guidance from the equipment vendor, align and insert each QSFP28 male connector into the corresponding port until the latch engages. Verify link and interface status on connected devices and configure the network interfaces or switch ports according to your network design. If required, consult the host equipment compatibility list to confirm full support for AOC assemblies.

Usage recommendations

Route the cable to avoid tight bends and mechanical stress; maintain the manufacturer’s minimum bend radius for multimode fiber. Use cable management to prevent strain on connectors and to keep airflow unobstructed in racks. For interoperability, deploy this cable where QSFP28 MSA-compliant ports and 100GBASE‑SR4 are supported, and validate links after installation with vendor-recommended diagnostics.
