It can test the light loss and locate the breaks, splices and connectors in fiber optic network. However, OTDR has "dead zone" which can affect the testing result if proper measure is not taken. To overcome the limitation of OTDR dead zone, OTDR
In this case a launch fiber of about 300 ft. is being used. This allows the OTDR to characterize the first connector of the link under test (B). (C) shows two connectors that are too close together for the OTDR to properly characterize the loss in each. (
OTDR Testing Process. The OTDR test process is dependent on the equipment type and the fiber optic cable run being tested, as well as the objective(s) of the test. However, there are some common OTDR testing procedures that are fundamental to any applicat
