The OTDR measures fiber attenuation, splice loss, and fault location. It features a 1625nm wavelength, 20dB dynamic range, and is compatible with single-mode fiber. With large internal storage and expandable 160GB via an external USB drive, it detects issues such as red-light leakage, fiber optic patch cords, near-end faults, and high-loss sections caused by micro-bending.

Feature

5-inch outdoor enhanced LCD touchscreen for smooth, real-time operation.
Embedded ARM processor with ultra-low power consumption.
Measures fiber optic cable length, loss, and splice quality, ideal for FTTH optical network testing.
Visible red light injection helps locate fiber faults by observing light leakage.
Suitable for detecting bare fibers, patch cords, fault points, and high-loss areas due to micro-bending.
Network line measurement detects breaks, short circuits, and disorder, supporting multiple line types and fault location.

Details

Application

OTDR (Optical Time Domain Reflectometer) measures fiber attenuation, splice loss, and fault location by analyzing the backward scattered light as it propagates through the fiber. It provides detailed information on the loss distribution along the fiber’s length. This makes the OTDR tester a crucial tool for fiber optic cable construction, maintenance, and monitoring.

Tips: How to judge the fiber quality of OTDR?

Attenuation: High loss indicates poor fiber quality due to damage or excessive distance.
Splice Loss: Keep splice loss under 0.1 dB for good quality connections.
Reflection: Low reflection (ORL) is ideal; high reflection suggests poor fiber or connectors.
Event Map: Look for sudden drops or spikes in the trace, indicating faults like breaks or poor splices.
