Product Description
NVIDIA MFA1A00-C050 – 100G Active Optical Cable for Data Center and Ethernet Networks
The NVIDIA MFA1A00-C050 is a high-performance QSFP28 active optical cable (AOC) designed for 100Gb/s Ethernet (100GbE) and InfiniBand EDR systems. This 50-meter variant provides extended reach up to 100 meters while maintaining excellent signal integrity and low power consumption.
Key Features
- Ultra-low power consumption (2.2W typical per end with retiming)
- Up to 100 meters reach on multimode fiber
- Hot-pluggable SFF-8665 compliant design
- Selectable retiming per lane for optimal performance
- Digital diagnostics and programmable signal integrity
- Aggregate data rate up to 100Gb/s (4 lanes × 25.78Gb/s)
- Programmable Rx output amplitude and pre-emphasis
- Programmable Tx input equalizer for lossy host links
- LSZH (Low Smoke Zero Halogen) jacket for safety
- RoHS compliant and hot-pluggable
Product Overview
Leveraging VCSEL-based multimode fiber technology, this active optical cable provides extended reach while maintaining excellent signal integrity. Ideal for top-of-rack switching, inter-rack connectivity, and high-density data center deployments, the MFA1A00 series offers programmable retiming, input equalization, and output pre-emphasis to optimize link performance in diverse environments.
Technology & Signal Integrity
The MFA1A00-C050 employs advanced retiming and equalization features to overcome channel impairments. Each lane integrates a clock and data recovery (CDR) circuit that can be bypassed for legacy or lower signaling rates. The programmable transmitter input equalizer compensates for host PCB losses, while the programmable receiver output amplitude and pre-emphasis ensure clean signal delivery.
Typical Deployments
- Data Center Interconnect: Connect top-of-rack switches to end-of-row aggregate switches within 100m distance
- High-Performance Computing (HPC): InfiniBand EDR fabrics for compute and storage clusters requiring low latency and high bandwidth
- Cloud & Enterprise Networks: 100GbE spine-leaf architecture, reducing power and cost compared to copper DACs beyond 5m
- Edge Computing Nodes: Reliable optical links in space-constrained racks where EMI immunity matters
- Media & Post-Production: High-speed file transfers for shared storage environments

Advantages
Extended Reach & Low Power
Up to 100m without repeaters, lower power than optical transceivers + patch cord solution, saving switch power budget.
AI-Ready Signal Integrity
Programmable equalization, retiming, and output pre-emphasis ensure robust links in noisy or lossy environments.
Operational Flexibility
Works with both InfiniBand EDR and 100GbE, supporting retiming bypass for legacy rates.
Direct Manageability
Full DDM via SFF-8636: real-time monitoring of temperature, voltage, optical power, and TX bias, simplifies maintenance.
Frequently Asked Questions
Q1: Is MFA1A00-C050 compatible with my Cisco 100G switch?
A: The cable is standard QSFP28 AOC. Most modern Cisco switches (Nexus 9300, 9500) with 100GbE ports will recognize it. However, for full Cisco IDPROM compatibility, we recommend verifying or request coding service.
Q2: What is the difference between retiming and non-retiming operation?
A: Retiming re-synchronizes and cleans the signal using CDR, achieving better signal quality for 25Gb/s per lane. If lower data rates are used (e.g., 10Gb/s), CDR can be bypassed to save power (down to ~1.5W).
Q3: Can I use this cable for 40GbE or breakout applications?
A: The MFA1A00 series supports 100Gb/s as four 25G lanes; it is not intended for 40GbE breakouts. For 4×25G breakout (QSFP28 to four SFP28), check other NVIDIA AOC products.
