Amount structural loss caused by the fiber transmission attenuation caused by reason and various faults of construction such as scattering, absorbing, when optical fiber
When a little by temperature or stress, the scattering properties of the point will change, therefore by showing loss and fiber lengths
Corresponding relation detects the disturbance information that outer signals are distributed on sensor fibre.
Actual test method, transmitting light pulse are carried out to the information that returns in optical fiber, is then received in OTDR ports.When
When light pulse is transmitted in optical fiber, the property due to optical fiber in itself, connector, abutment, bending or other similar events are understood
