MultiLane ML7008F-LFT 224G BERT
The ML7008F-LFT is a high-performance 224 Gb/s per lane Bit Error Rate Tester (BERT) from MultiLane, designed for validation and characterization of next-generation 224G PAM4 interconnects used in 1.6T Ethernet, AI clusters, and hyperscale data-center networks.
Unlike traditional BERTs, the ML7008F-LFT is built around the same class of advanced SerDes technology used in modern 1.6T switch ASICs, allowing engineers to emulate real-world operating conditions during compliance, interoperability, and signal-integrity testing.
Key Features
224 Gb/s PAM4 Testing
- Supports up to 224 Gb/s per lane
- Designed for emerging 1.6T networking ecosystems
- Suitable for validating cables, connectors, backplanes, and optical modules
Advanced Receiver Equalization
- More than 40 dB Rx equalization
- Enables testing across highly lossy channels
- Helps evaluate long-reach and challenging interconnect designs
Real-Hardware FEC
The platform includes actual Forward Error Correction processing rather than software emulation.
Benefits include:
- Accurate post-FEC measurements
- Realistic link behavior
- System-level validation
BLER Measurements
Supports Block Error Rate (BLER) testing for:
- Link performance evaluation
- FEC effectiveness analysis
- Compliance and qualification testing
Link Training Support
The ML7008F-LFT can perform:
- PAM4 link training
- Adaptive equalization testing
- Real-world interoperability validation
This is particularly important for 224G SerDes deployments where link training plays a critical role in achieving reliable communication.
Flexible Transmitter Architecture
16-Tx Option
The optional 16-transmitter configuration supports:
- High-voltage applications
- Low-voltage applications
- Multi-lane characterization
- Advanced interoperability testing
This flexibility allows engineers to evaluate a broad range of ecosystem components.
Applications
AI and Hyperscale Networking
Used for validation of:
- 1.6T switches
- AI accelerator fabrics
- Ethernet infrastructure
- High-speed backplanes
Optical Module Testing
Supports evaluation of:
- 1.6T optical transceivers
- OSFP1600 modules
- Co-packaged optics
- Active electrical cables
Interconnect Characterization
Suitable for testing:
- PCB channels
- Connectors
- Copper cables
- Retimers
- DSP-based optical modules
Deployment Options
Standalone Instrument
Can be deployed as an independent lab instrument for:
- Research
- Development
- Validation
MultiWave Platform Integration
Also available as the MW7008F-LFT module for the MultiWave Test Platform, enabling scalable multi-port testing and automated validation environments.
Typical Use Cases
| Application | Purpose |
|---|---|
| SerDes Validation | Verify 224G transmitter and receiver performance |
| FEC Testing | Measure pre-FEC and post-FEC error rates |
| Link Training Analysis | Validate adaptive equalization behavior |
| Optical Qualification | Characterize next-generation transceivers |
| Signal Integrity | Stress and evaluate high-loss channels |
| Manufacturing Test | Production screening and quality assurance |
Why It Stands Out
The ML7008F-LFT combines:
- 224G PAM4 capability
40 dB receiver equalization
- Real-hardware FEC processing
- BLER analysis
- Link training support
- Flexible transmitter configurations
These features make it one of the most comprehensive solutions available for validating the rapidly evolving 224 Gb/s per lane ecosystem, which forms the foundation of modern 1.6T Ethernet, AI networking, and next-generation data-center infrastructure.
