Product Description

NVIDIA MFA1A00-E020 100Gb/s QSFP28 Active Optical Cable

1. Product Overview

The NVIDIA® MFA1A00-E020 is a high-performance QSFP28 Active Optical Cable (AOC) engineered for 100Gb/s InfiniBand EDR and Ethernet applications. This Optical Fiber Cable delivers a robust 20-meter reach, significantly outperforming passive copper solutions in data center environments. It integrates four multi-mode fibers (MMF) per end, each capable of transmitting data at speeds up to 26 Gb/s. Designed for high port density and hot-pluggable convenience, this passive fiber cable alternative offers superior configurability and power efficiency, making it an ideal choice for modern high-speed interconnects.

2. Key Characteristics

  • Data rates up to 100 Gb/s for high-bandwidth applications
  • Hot-pluggable QSFP28 form factor for easy installation and maintenance
  • Programmable receiver output amplitude and pre-emphasis for signal integrity
  • Selectable retiming per lane for optimized performance at 26 Gb/s
  • Low power consumption: 2.2W typical per end (with retiming)
  • Reach of up to 100 meters with multi-mode fiber
  • Compliant with SFF-8665, SFF-8636, and RoHS standards
  • Digital Diagnostic Monitoring (DDM) for real-time performance tracking

3. Core Technology & Standards

The MFA1A00-E020 leverages Vertical Cavity Surface-Emitting Laser (VCSEL) technology to ensure reliable data transmission. It fully complies with key industry standards, including SFF-8665 for the QSFP28 interface and SFF-8636 for the I²C management interface. This Optical Fiber Cable supports 100GbE Ethernet and InfiniBand EDR protocols, ensuring broad interoperability. Its advanced firmware enables sophisticated Digital Diagnostic Monitoring (DDM), providing insights into temperature, voltage, laser bias, and optical power levels.

4. Working Principle

This active optical cable functions by converting electrical signals from the host system into optical signals via integrated VCSEL transmitters. These optical signals are then transmitted over the multi-mode fiber. At the receiving end, optical detectors convert the signals back into electrical data. The cable features built-in retiming capabilities (CDR) on each lane to correct signal jitter and distortion, ensuring data integrity over extended distances. This integrated approach eliminates the need for separate transceivers and patch cables, simplifying the link and enhancing reliability. This passive fiber cable alternative is a complete, plug-and-play solution.

5. Application Scenarios

The MFA1A00-E020 is designed for high-performance computing environments that demand low latency and high bandwidth.

  • Data Center Interconnects: Spine-leaf architecture, top-of-rack (ToR) switching, and server-to-switch connections.
  • High-Performance Computing (HPC): Clusters and supercomputers utilizing InfiniBand EDR.
  • Cloud Infrastructure: Large-scale cloud service providers requiring high-speed server interconnects.
  • Enterprise Networks: Core networking and storage area networks (SANs).

9. Frequently Asked Questions (FAQ)

Q: Is this cable hot-pluggable?
A: Yes, the QSFP28 form factor is designed for hot-pluggable operation, allowing for installation and removal without powering down the system.

Q: What is the difference between an AOC and a passive DAC?
A: An Active Optical Cable (AOC) like this one uses fiber optics and has built-in electronics for signal processing, allowing for longer reaches (up to 100m) and less weight. A Passive Direct Attach Copper (DAC) cable is heavier, has a shorter reach (~5-7m), and contains no active components.

Q: Does this cable support digital diagnostics (DDM/DOM)?
A: Yes, it features full Digital Diagnostic Monitoring (DDM) according to SFF-8636, providing real-time data on temperature, voltage, TX/RX power, and laser bias current.

Q: What systems is this cable compatible with?
A: It is compatible with any switch, router, or network interface card that features a QSFP28 port and supports 100GbE or InfiniBand EDR protocols. Always consult your system's compatibility guide.

10. Important Precautions

  • Ensure the host equipment's QSFP28 port is enabled for the appropriate protocol (100GbE or InfiniBand EDR).
  • Do not exceed the minimum bend radius of 30 mm to prevent permanent damage to the internal fibers.
  • Operate and store the cable within the specified temperature and humidity ranges (0°C to 70°C operating; 5% to 85% humidity).
  • This equipment complies with FCC Class A limits. It may cause radio interference in residential areas; mitigation is the user's responsibility.
  • The laser module is classified as IEC 60825-1 Class I laser product, which is safe under normal operating conditions.
