  • Page 8: Basic Knowledge Of Otdr

    2. Basic Knowledge An Optical Time Domain Reflectometer (OTDR) is a precision optical fiber measurement instrument made by using the principle of back- scattering generated by Rayleigh scattering and Fresnel reflection when laser light is transmitted in optical fiber. It measures the transit time of a light pulse back and forth, uses the formula L=c×t/(2n) to calculate the distance L, the unit of L is m, c is the propagation speed of light in vacuum 2.99792×...
  • Page 9 various connection points, fusion points and bending, cracking or breaking positions in the optical fiber link that lead to the loss of transmission signals, mainly divided into reflection events and non-reflection events. 1）Reflective event When the laser pulse sent by the OTDR is transmitted along the fiber under test, if it encounters an active connection point or the end of the fiber, reflection will occur due to the sudden change of the refractive index, and part of the optical signal will return to the OTDR along the fiber under test.
  • Page 10 as a signal with a drop in energy on the OTDR curve, and the magnitude of the drop indicates power loss. 3） ） ） ） Dynamic Range Dynamic range is an important parameter of optical time domain reflectometry, it is measured in dB. This parameter is expressed as the maximum optical loss that the OTDR can analyze from the back-scatter level at the output port of the OTDR down to a specific noise level.
  • Page 11 the next Fresnel reflection signal by OTDR is defined by the pulse width less than 1.5dB of the peak value. Attenuation Blind Zone: The shortest distance that an OTDR goes through from detecting Fresnel reflection signal to normal testing backward Rayleigh scattering signal, that is, the phase cannot measure fusion loss due to adjacent large reflection.

  • Page 55: Common Problems And Solutions

    5. Common problems and Solutions 5.1 How to observe the optical pulse waveform? Pulsed light emitted by OTDR injects into different locations of the measured optical fiber links, which can cause loss, such as connection points, bends and end of the optical fiber.
  • Page 56 Splice loss: Due to the uneven density of the welded parts or the change of material quality, the increase of Rayleigh scattering loss results in the welding loss. Reflection of Connector: There is a small gap in the connecting part of the connector, and the group refractive index of the gap changes, so the reflection occurs and causes loss.
  • Page 57 （ （ （ （ 2） ） ） ） Curves Have Large Steps If there is an obvious "step" in the lower right figure, if this is the joint, it means that the joint is not qualified or that the bending radius of the optical fiber is too small or squeezed in the fused disc;...
