  • Page 16: 3: Introduction Of Otdr

    Let’s go in the grandway! 3: Introduction of OTDR Purpose of Measurement OTDR shows the back-scatter light power of the optical signal relative to the distance. With this information, the OTDR could measure a series of important information of an optical fiber such as the quality of the line, distance of the line and etc.
  • Page 17 Let’s go in the grandway! Normal Curve A normal trace shows as above, the A mark is a start-peak and the B mark is a end-reflection-peak. The tested trace is oblique, the total loss will become bigger with the increasing of the fiber length. The total loss(dB) divides total length is the average loss(dB/km) of a fiber.
  • Page 18 Let’s go in the grandway! Curve with Broken Point If the tested trace is just like the figure shows above, this might be caused by several reasons like: a bad connection between the connector and the lunching port, the optical pulse cannot be launched into the optical fiber or a short distance broken point of the tested fiber from the initial connection and the preset testing distance and pulse width is larger.
  • Page 19 Let’s go in the grandway! non-reflection event. If the direction is upward, we can call it reflection event. Sometimes, the loss value could be a negative value, it does not means the loss does not exist. It is common phenomenon called pseudo gain, it is by a connection of two fibers with different back scatter coefficient, the scatter coefficient of the back fiber is large than the front one's.
  • Page 20 Let’s go in the grandway! Fundamental of OTDR OTDR——Optical Time Domain Reflector is a high precision optical testing meter that use the theory of Rayleigh scattering and Fresnel reflection. It is widely used in the maintenance, construction and monitoring of an optical line. All the important parameters like fiber length, optical loss, connection loss, broken or twisted point and etc.
  • Page 21 Let’s go in the grandway! Working Principle of OTDR Event Type of OTDR Start event or non reflection event Reflection event End event Types of event The events on trace are all the points that the value of power loss fluctuates abnormally. It usually contains various types of connection and bending, crack, broken and etc.
  • Page 22 Let’s go in the grandway! End event The End-Event on a OTDR trace is the end point of a fiber. Under the default setup, End-Event is located on the last event(usually it is an end face or a broken down point of a fiber). Usually, it is a Reflection-event.
