OTDR testing machine

5-inch color touch screen UI design, intuitive and easy to use

  • The multi-functional OTDR fiber optic tester features a 5-inch outdoor enhanced LCD touchscreen for smooth, real-time user operation.
  • Embedded ARM processor, ultra-low power consumption, and smooth operation.
  • OTDR machine is mainly used to measure fiber optic cable length, loss, and splice quality parameters for fiber optic end test, fiber to the home, especially FTTH optical network testing to provide a comprehensive solution.
  • The visible light (red light) is injected into the optical fiber, and the location of the optical fiber fault point can be easily and accurately determined by observing the position of light leakage on the tested fiber. Multi-functional OTDR fiber optic tester is suitable for the detection of bare fibers, fiber optic patch cords, and other fibers that can leak red light, near-end fault points of fiber optic cables, and high loss areas caused by micro-bending.
  • Network line sequence measurement can detect the network line break, short circuit, or disorder, support different types of network line length measurement, and can roughly check the network line fault location point.


OTDR (optical time domain reflectometer) uses the backward scattered light generated when the light propagates in the fiber to obtain attenuation information, which can be used to measure fiber attenuation, splice loss, fiber fault location and understand the loss distribution along the length of the fiber, etc. OTDR tester is an essential tool in fiber optic cable construction, maintenance, and monitoring.

OTDR fiber optic tester details


Q1: What is an OTDR used for?
A1: OTDR is a fiber optic instrument used to characterize, troubleshoot and maintain optical communication networks. OTDR testing is performed by transmitting and analyzing pulsed laser light through an optical fiber.

Q2: What is fiber loss?
A2: Optical fiber loss is the attenuation per unit length of optical fiber in dB/km, the level of fiber loss directly affects the transmission distance or the distance between relay stations, therefore, understanding and reducing the loss of optical fiber is of great practical significance for fiber optic communication.

Q3: What is an optical time domain reflectometer?
A3: The optical time domain reflectometer is a fiber optic tester used to test the characteristics of optical communication networks. OTDR is designed to detect, locate and measure events at any location on a fiber optic link. OTDR requires access to only one end of the link and works in a manner similar to a one-dimensional radar system. By providing graphical trace characteristics of the fiber under test, the user can obtain a graphical representation of the entire fiber link.

Tips: How to clean the joints of the OTDR tester?

Before the fiber or connector is connected to OTDR, it must be carefully cleaned, including the output connector of OTDR and the live connector under test, otherwise, the insertion loss is too large, the measurement is unreliable, the curve is much noisy or even make the measurement can not be performed, it may also damage the OTDR. avoid using other cleaning agents other than alcohol or refractive index matching solution, because they can make the adhesive inside the fiber connector dissolve.
