BlueOptics MFA1A00-E003-BO InfiniBand/fibre optic cable 3 m QSFP28

The BlueOptics MFA1A00-E003-BO InfiniBand/fibre optic cable 3 m QSFP28 is a 3‑meter active optical cable (AOC) with QSFP28 male connectors on both ends designed for high‑speed links in data centers and high‑performance computing environments. The cable implements multimode fibre optics with integrated transmitter and receiver modules at each end, supporting short‑reach 100GBASE‑SR4 and compatible with equipment that follows MSA QSFP28 interface specifications.

Advantages

This 3 m QSFP28 active optical cable delivers consistent 100 Gbps connectivity over multimode fibre for low-latency, high-bandwidth links. As an AOC with integrated optics it reduces the need for separate transceivers and patch cords, simplifies cabling between switches, routers and storage systems, and helps maintain signal integrity at high data rates. The cable is compatible with systems that support the referenced 100GBASE‑SR4 QSFP28 form factor and is suited for dense racks and short interconnect distances in modern network infrastructures.

Suitable for

• High-performance computing clusters and InfiniBand fabrics
• Data center switch-to-switch and switch-to-server connections
• 100G Ethernet and Fibre Channel over Ethernet short‑reach links
• Storage systems and aggregation fabrics requiring QSFP28 connections

Key specifications

• Cable type: Active Optical Cable (AOC) with multimode fibre
• Length: 3 metres
• Connector type: QSFP28 male to QSFP28 male
• Supported data rate: up to 100 Gbps (100GBASE‑SR4 compatible)
• Transmission medium: multimode optical fiber with integrated transmitter and receiver modules
• Form factor compatibility: QSFP28 MSA compliant short‑reach applications

How to use

Insert each QSFP28 connector into the corresponding QSFP28 port on your network devices, ensuring the latch engages and the connector is fully seated. Use the cable for short‑reach 100G links such as switch-to-switch, switch-to-server or switch-to-storage interconnects. No separate transceivers or patch cords are required; the integrated optics handle signal conversion. Verify that your hardware firmware and configuration support 100GBASE‑SR4/QSFP28 AOC connections before deployment.

Usage recommendations

Route the cable to avoid tight bends and mechanical strain; maintain the manufacturer’s minimum bend radius for multimode fibre. For optimal operation, confirm device compatibility with QSFP28 AOCs and ensure adequate airflow in dense rack environments to prevent thermal issues around QSFP ports.
