The loss of the connector is calculated by the aid of OTDR

Fiber optic signals, equipments called optical time domain reflectometry (OTDRs), measure the length of an optical fiber and the attenuation of an optical fiber, scattered over a range of distances. The OTDR can alert the technician of splice and fiber breakage. These devices send test pulses through the system, waiting for the return signal. Quality and the occurrence of a return tell the technician that both are good or system faulty.
1.OTDR system connected to a fiber need to test and send the initial pulse. After the test results come in, you will get a readout plot.

2.Select the “two loss” option for data interpretation. This is used to measure the loss and distance of two specific markers, and it can also be determined that a connector has been lost.

3.Look at this chart to determine the loss between the two marks. The distance is usually the horizontal axis, and the fiber loss is usually the vertical axis. Read the vertical first marker and the second marker. The calculation will see the difference in fiber strength loss. If a connector is located between the two tags, the calculation will still be the same.
