MAIN FUNCTIONS OF OTDR

What is OTDR An optical time-domain reflectometer (OTDR) is an optoelectronicinstrument used to characterize an optical fiber An OTDR is the opticalequivalent of an electronic time domain reflectometer It injects a series ofoptical pulses into the fiber under test

It also extracts from the same end of the fiber light that is scattered(Rayleigh backscatter) or reflected back from points along the fiber (This isequivalent to the way that an electronic time-domain reflectometermeasures reflections caused by changes in the impedance of thecable under test) The strength of the return pulses is measured andintegrated as a function of time and is plotted as a function of fiber length

Main functions of OTDR

1 Fast automatic testAutomatic test function allows the user not to have to know more

details about the equipment operation test steps become very simple Useronly needs to connect in the optical fiber click ldquoTestrdquo button then theinstrument will automatically set optimal test conditions and eventually giveaccurate test results such as the test curve and event lists

2 Fast curve analysisIt can find out the event point or failure point in test curve and its location

information quickly and accurately test curve and list all event informationin the circuit in the form of event list This is very helpful for circuitmaintenance personnel not only improves the testing efficiency but alsoeliminates the need to learn difficult background knowledge

3 Powerful document managementIn addition to the ability to store view delete the files in the machine it

also provides PCL language-based laser or jet printers to print testreports Besides it also utilizes PC software to realize high-speedcommunications with PC via USB cable

4 Convenient VFL functionWith visual IR VFL function it can easily and quickly find the locations of

disconnecting points or big loss points in short-distance optical fiber linksso that the maintenance personnel could take measures in shortest timetherefore saving a lot of time

5 Manual test modeUsers can choose real-time test mode or average test mode according to

the testing needs Real-time test can fast test the dynamic change ofoptical-fiber links It is mainly used for the connecting occasions requiringmonitoring or observing optical-fiber links at real time

6 Average test modeAverage test mode is used to withhold the noise in test curves to the most

extent therefore obtain more accurate testing results In average test modethe number of averaging tines will influence the effects of suppressing thenoise in test curves The bigger the number of time is the effect the time isbut the testing time is to be extended accordingly Therefore user shouldset averaging time based on actual need
