An OTDR-2000 handheld optical time domain reflectometry is a new generation of handheld intelligent optical fiber communication measuring instruments, can show a loss of optical fiber and cable distribution curve, measuring the attenuation coefficient of fiber and fiber optic cable between two points loss and splice loss measurement of fiber and cable length, the distance between two points to determine the fiber-optic cable connection point, fault point and the location of the breakpoint. Widely used in the construction of fiber optic communication systems, the maintenance of measurement and emergency repairs; measurement of the development and production of optical fiber and cable. 

 One main function: 

 The test fiber length. 

 The distance between any two points on the curve of the test fiber. 

 Test and displays the curve between any two points in loss (dB). 

 Test and shows the connection point on the curve of the connection loss (dB). 

 Test reflection loss value. 

 The connection point of the automatic search function. 

 Test Waveform store. 

 Intelligent battery indicator. 

 Real-time test function to facilitate the observation of fiber-optic real-time docking results.
