NVIDIA MFA1A00-C050 100Gb/s QSFP28 Active Optical Cable
1. Product Overview
The NVIDIA® MFA1A00-C050 is a high-performance QSFP28 Active Optical Cable (AOC) designed for 100Gb/s Ethernet applications. This Optical Fiber Cable leverages VCSEL-based technology to deliver reliable, high-speed data transmission over multimode fiber (MMF), supporting distances of up to 50 meters. It is an ideal solution for data centers and high-performance computing environments requiring high bandwidth, low latency, and low power consumption.
2. Key Characteristics
- Data rate up to 100Gb/s per cable
- Hot-pluggable QSFP28 form factor
- Low power consumption: 2.2W typical per end (with retiming)
- Digital Diagnostic Monitoring (DDM) via I²C
- RoHS compliant and LSZH jacket
- Programmable Tx equalization and Rx output settings
3. Technology & Standards
The MFA1A00-C050 complies with SFF-8665 and SFF-8636 standards. It supports 100GBASE-SR4 Ethernet and is interoperable with InfiniBand EDR systems. The cable uses four 25.78 Gb/s lanes with optional retiming for signal integrity.
4. Working Principle
The AOC converts electrical signals into optical signals via VCSEL transmitters, transmits light over multimode fiber, and converts back to electrical signals at the receiving end. Integrated signal retiming and equalization ensure low bit error rate (BER < 10⁻¹⁵) over extended distances.
5. Applications
- Data center spine-leaf architectures
- High-performance computing clusters
- Cloud infrastructure and hyperscale networking
- Storage area networks (SANs)
- AI and machine learning workloads
