Product Features
1.High Precision and Extended Dynamic Range
Delivers up to 35/33 dB dynamic range, expandable to 45 dB, enabling accurate testing of long-haul fiber links.
With a distance resolution of 0.05 m and a minimum event dead zone of just 0.8 m, the system reliably detects short-distance events and subtle signal losses.
2.All-in-One, Modular Test Platform
Supports SM, MM, or hybrid configurations, with two/ three/ four-wavelength options to match diverse network environments.
Integrated OTDR, light source, optical power meter, VFL, end-face inspection, and network testing functions reduce the need for multiple instruments and lower total equipment costs.
3.Intelligent Diagnostics & Efficient Operation
Built-in self-diagnostic analysis improves test accuracy and result reliability.
Customizable Pass/Fail criteria, multi-trace comparison, and one-click PDF report generation streamline on-site verification and documentation.
4.Remote and Live Network Testing
Supports Ethernet-based remote OTDR control, making it suitable for unattended testing and centralized maintenance operations.
Optional online testing modules enable non-intrusive testing of live fiber links, allowing measurements without service interruption.
5.Flexible Expansion & Industry Compatibility
Equipped with multiple interfaces including USB-A, USB-C, Ethernet, and Bluetooth for seamless connection to USB storage devices, end-face microscopes, and PCs.
Test data complies with SOR industry standards, ensuring smooth file sharing and compatibility with third-party analysis software.
OTDR Testing
Supports up to four wavelengths
Features event mapping, macro-bend analysis, and four-point/LSA curve analysis. Configurable start/end fibers with customizable threshold detection.

Optical Laser Source (OLS) and Optical Power Meter (OPM)
Light source supports CW, 270 Hz, 1 kHz, 2 kHz modulation.
Wide optical power meter measurement range (+70 dBm to +26 dBm), supports multi-wavelength identification.

Visual Fault Locator (VFL)
Supports continuous 1 Hz/ 2 Hz visible red light for rapid fiber fault location.
