Product Description
NVIDIA MFA1A00-C050 100G QSFP28 MMF AOC
High-performance 100Gb/s QSFP28 active optical cable designed for medium-reach interconnects in data centers. Supports 4× 25Gb/s NRZ modulation with selectable retiming per lane for reliable, power-efficient connectivity in 100 Gigabit Ethernet and InfiniBand EDR systems.
Product Overview
The NVIDIA MFA1A00-C050 is a QSFP28 VCSEL-based active optical cable that provides 100Gb/s aggregate bandwidth over multimode fiber. This 50-meter variant offers an optimal balance of reach and cost, featuring four independent optical transceivers per end operating at up to 25.78Gb/s with NRZ modulation. Fully compliant with SFF-8665 and SFF-8636 standards, it supports hot-pluggable installation and I²C management with typical power consumption of only 2.2W per end when retiming is enabled.
Key Features
- Data rate: Up to 100Gb/s (4× 25.78Gb/s NRZ)
- Protocol support: 100GbE, InfiniBand EDR
- Reach: Up to 100m over multimode fiber
- Low power: 2.2W typical per end (with retiming)
- Hot-pluggable: QSFP28 form factor, SFF-8665 compliant
- Management: SFF-8636 I²C interface with DDM
- Programmable: Rx output amplitude & pre-emphasis, Tx input equalizer
- Compliance: RoHS, Class 1 laser safety
Technology & Design
The MFA1A00-C050 employs VCSEL (Vertical Cavity Surface-Emitting Laser) technology at 850nm wavelength coupled with high-speed multimode fiber. Each lane features independent retiming for both transmit and receive paths, enabling superior signal integrity. The cable integrates digital diagnostic monitoring (DDM) for real-time tracking of optical power, temperature, voltage, and bias current. Programmable Tx equalization and Rx output amplitude/pre-emphasis allow fine-tuning for varying host board conditions. The LSZH (Low Smoke Zero Halogen) jacket ensures safety in data center environments.
Typical Deployments

- Cloud service providers: Cost-effective 100G connectivity for public and private clouds
- AI/ML training clusters: High-bandwidth, low-latency connections for GPU-based systems
- Enterprise campus networks: Aggregation links between distribution and core switches
Compatibility

Frequently Asked Questions
Q: What is the difference between AOC and DAC?
A: An AOC (Active Optical Cable) uses optical fiber with integrated transceivers to achieve longer reach (up to 100m) than passive copper DACs (typically ≤5m), while offering lower weight and better EMI immunity.
Q: Can I use this cable with InfiniBand EDR switches?
A: Yes, the MFA1A00 series supports both InfiniBand EDR (E-series) and 100GbE (C-series). For EDR, use the MFA1A00-Exxx variants.
Q: What is the difference between C-series and E-series?
A: The C-series is optimized for 100GbE applications, while the E-series is optimized for InfiniBand EDR. Both use the same physical hardware but may have different firmware configurations.
Q: What is the minimum bend radius of this cable?
A: The minimum bend radius is 30 mm.
Q: Is the cable hot-pluggable?
A: Yes, it is fully hot-pluggable and supports live insertion/removal without powering down the host system.
Q: What is the maximum distance for this cable?
A: The MFA1A00 series supports up to 100m over OM3/OM4 multimode fiber. The C050 variant is 50m.
Handling Precautions
- Keep protective dust caps on connectors until installation to prevent contamination
- Use approved optical connector cleaners before mating to ensure low insertion loss
- Avoid bending the cable tighter than the 30 mm minimum bend radius
- Observe standard ESD precautions during installation and handling
- Do not pull on the connectors; use the pull-tab or latch for insertion/removal
