Several projects have tried to determine how to corellate OTDR measurements to source and power meter measurements, without success. Our experience is an OTDR will measure 6-7 dB of loss for a multimode cable plant that tests at 10 dB with a source and power meter. down the fiber and looks for a return signal from fiber backscatter and reflections from joints, creating a display called a "trace" or "signature" from the measurement of the fiber. From this trace, the OTDR Most OTDRs give a choice of at least five different pulse length from which to select. Low pulse widths mean good separation of events but the pulse has a low energy content so the maximum range is very poor. A pulse width of 10ns may well provide a maximum range of only a kilometer with a range discrimination of 1 meter.

Overview OTDR - Optical Time Domain Reflectometer . 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. An ancient symbol with many uses, the star can take on different meaning based on both its context and its number of points. Because they are some of the most distant bodies we can see with the naked eye, stars can symbolize physical distance, such as a journey, or emotional distance, such as a misunderstanding.

( O ptical T ime D omain R eflectometer) A test instrument that analyzes the light loss in an optical fiber. Used to find faults, splices and bends in the line, it works by sending out a light pulse and measuring its reflection. Such devices can measure fiber lines that are longer than 150 miles. Making OTDR Measurements .doc, 12/25/18, 1 More On Optical Time Domain Reflectometers (OTDRs) We seem to not be able to say enough about OTDRs, since they are so poorly understood and routinely misused.
Using an OTDR need not be complicated or confusing. Understanding a few basic concepts will make OTDR use as straightforward as using a copper certification tool. The two most common tools used for fiber-optic cable testing are power meters and optical time-domain reflectometers (OTDRs).

It can verify splice loss, measure length and find faults. The OTDR is also commonly used to create a "picture" of fiber optic cable when it is newly installed. At first, the OTDR trace can seem a bit overwhelming. The OTDR trace tells a story about each fiber it tests. A certain dip or spike known as an event can reveal the type of connection. Lets take the example below: In the case of an OTDR, the consecutive event is detected, but the loss cannot be measured. The OTDR merges the consecutive events and returns a global reflection and loss for all merged events.
