2.2.2 Non Reflective Events
When the laser emitted from the OTDR pulse to be measured along the optical fiber
transmission, such as melting point or bending leads to some loss of energy when the location
does not exist at this time due to mutations in the refractive index, so the reflection phenomenon
will not occur, or can be ignored. OTDR detects the difference of the energy change of the
receiving end of the OTDR, which can be used to detect the non reflection event parameters.
Non reflection events declined as a signal energy in the test curve of OTDR, the decrease of said
power loss situation. As shown in Figure 2-2.
