    Multi functional otdr

    All-in-one multi-functional OTDR fiber tester

    • Measure the loss of splicing points, optical connectors, and adapters.
    • Measure the loss of a single fiber or cable.
    • Measure the length of the cable, and set different refractive indices for various fibers.
    • Locate the position of a broken point, Optical connector, and adapter.
    • Measure the discrete reflection ratio between SR points.
    • Measure return loss for the whole fiber circuit including connecting points and S points.


    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.

    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: Why is the test data of the optical time domain reflectometer unstable?

    • The setting parameters of the optical time domain reflectometer are unreasonable.
    • The optical time domain reflectometer's built-in fiber optic adapter is dirty or damaged.
    • The optical module of the OTDR is damaged.
