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 choose the wavelength of the OTDR fiber optic tester?

1550 wavelength test distance is longer, 1550nm than 1310nm fiber more sensitive to bending, 1550nm than 1310nm unit length attenuation is smaller, 1310nm than 1550nm measured fusion or connector loss is higher. In the actual fiber optic cable maintenance work is generally tested and compared for both wavelengths. For positive gain phenomenon and over the distance line are required to carry out two-way test analysis and calculation, in order to obtain a good test conclusion.
