Product Description
NVIDIA MFA1A00-C015 100G QSFP28 MMF AOC
High-performance 100Gb/s QSFP28 active optical cable designed for short- to medium-reach interconnects in data centers, supporting 100 Gigabit Ethernet and InfiniBand EDR systems.
Product Overview
The NVIDIA MFA1A00-C015 is a QSFP28 VCSEL-based active optical cable that provides 100Gb/s aggregate bandwidth over multimode fiber. It integrates four independent optical transceivers per end, each operating at up to 25.78Gb/s with NRZ modulation. Fully compliant with SFF-8665 and SFF-8636 standards, this cable supports hot-pluggable installation and I²C management with typical power consumption of only 2.2W per end.
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
- SFF-8636 I²C interface with digital diagnostic monitoring
- Programmable Rx output amplitude & pre-emphasis, Tx input equalizer
- RoHS compliant, Class 1 laser safety
Technology & Design
The MFA1A00-C015 employs VCSEL 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 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. LSZH jacket ensures safety in data center environments.
Typical Deployments
- 100GbE data centers: Connect top-of-rack switches to servers and storage systems

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 power consumption without retiming?
A: Without retiming, power consumption is 1.5W typical per end, making it ideal for lower-speed or power-sensitive applications.
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
