BlueOptics MFA1A00-E020-BO InfiniBand fibre optic cable 20 m QSFP28 Male Male

The BlueOptics MFA1A00-E020-BO InfiniBand fibre optic cable 20 m QSFP28 Male Male is a 20-meter active optical cable (AOC) with QSFP28 connectors on both ends. Designed for 100G environments, it implements 100GBASE-SR4 multi-mode transmission and integrates optical transmitters and receivers in the connector housings. The cable follows MSA (Multi-Source Agreement) specifications and is intended for use in high-density data center and high-performance computing installations that require reliable, low-latency optical links.

Advantages

This 20 m QSFP28 AOC offers high-speed 100G data transmission over multimode fiber with immunity to electromagnetic interference and reduced signal attenuation compared with copper alternatives. Integrated digital diagnostics monitoring (DDM/DOM) enables real-time readout of supply voltage, laser bias, output and received power, and temperature for simplified troubleshooting and maintenance. The pre-assembled, plug-and-play design eliminates the need for field polishing or patching, reducing installation time and the risk of connector-related signal loss.

Suitable for

• 100G Ethernet switch-to-switch or switch-to-server links in data centers
• High-performance computing clusters and InfiniBand fabrics
• Storage area networks (SAN) and high-throughput storage systems
• Low-latency interconnects in virtualized and cloud infrastructures

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Length: 20 meters
• Rated bitrate: up to 100 Gbps (100GBASE-SR4 compliant)
• Transmission medium: multimode fiber (active optical cable)
• Protocol support: Ethernet, Fibre Channel over Ethernet, InfiniBand compatible
• Monitoring: Digital Diagnostics Monitoring (DDM/DOM) compliant with SFF-8472
• Electromagnetic immunity: intrinsic to fiber optic transmission

How to use

Install the BlueOptics MFA1A00-E020-BO by inserting each QSFP28 plug firmly into the corresponding QSFP28 ports on your devices, ensuring correct orientation and full seating of the connector latch. Verify that connected hardware supports QSFP28 AOC modules and any required DDM/DOM functionality if diagnostic monitoring is required. After insertion, confirm link status and speed via the device management interface and monitor DDM parameters when performing troubleshooting or validation.

Recommendations

Use this AOC for short- to medium-reach 100G links within racks and between adjacent racks. Avoid tight bends and maintain the cable minimum bend radius to preserve optical performance. Confirm hardware compatibility with QSFP28 AOC modules and enable DDM/DOM support in the host system to access diagnostic data.
