An Optical Time Domain Reflectometer (OTDR) is an important instrument used by organizations to certify the performance of new fiber optics links and detect problems with existing fiber links.
OTDR

- The distance range setting on an OTDR controls the display range for the amount of cable to be presented on the screen;
- It also defines the rate of pulse emission;
- An OTDR contains a laser diode source, a photodiode detector and a highly accurate timing circuit (or time base)
