- Compact, integrated and rugged design for field deployment
- Lightweight and portable, ideal for outdoor operation
- One-button automatic testing for fast and efficient measurement
- Real-time trace monitoring for splice and maintenance applications
- Built-in high-power Visual Fault Locator (VFL) for precise fault location
- Optional 1625 nm live testing module with filter for FTTx / PON networks
- OTDR input protection to prevent damage from unexpected optical signals
- Dual USB host ports and one USB device port for PC control and external device connection
- 8 GB internal memory, capable of storing over 80,000 trace curves
- PC software for trace analysis, report generation and printing
- Long battery life designed for extended field operation
- User-friendly interface with Chinese and English language support
- Supports dual, triple and quad wavelength configurations
