TWH-6125 Optical Time Domain Reflectometer - OTDR

Function Introduction

Automatic test mode: OTDR will not need to select test distance and test pulse width. The system will automatically judge the length of the optical fiber cable and choose the proper test scope and test pulse width as well as the curve line will be an automatic or manual option to storage which is convenient for data analysis.

Multi wavelength test mode: When setting up the test parameter you can choose the double wavelength test mode, then the system will automatically switch the wavelength to carry out measurement to the effect of using different wavelength to make a measurement of loss in the same section of fiber cable in order to make a data analysis.

Multi curve line analysis function: It is available to make a comparison between any different curve line document and to make a displaying of analysis and calculation. Up to 4 curve lines can be displayed at same time.

High volume Polymer lithium battery: Super long standby time enables long time measurement application.

On line optical inspection: This function can effectively protect the OTDR itself and communication equipment.

Double maneuvering mode: Pure touch screen operation or pure physical key operation which can equally realize all functions which are convenient to the different operation habit of the engineers 

Data analysis: The OTDR can storage and generate the standard curve line documents(.sor). More than 20000 storage volume can easily realize the print of analysis report and curve line print which are convenient to the check and acceptance of the project.
