All OTDRs regardless of brand have four basic setup requirement i.e. the OTDR user is required to key in these four basic data parameters into OTDR in order to get good and accurate fiber trace analysis.
The required data parameters are :-
What is Averaging ?
Averaging refers to time taken to have a good OTDR traces as shown below.
However, the longer averaging time would provide better OTDR traces but it wil be time consuming for OTDR to provide such traces.
The before averaging or low averaging is sufficient should the end-user only interested to find out the approximate fiber optics link distance.
The about right averaging is able to provide good measurement loss.
The higher averaging time provides better OTDR traces but OTDR takes extra times to do the averaging and display better traces.
I have been in the field of fiber optics since early 1990s. I gained fiber optics skills and knowledge via my working experience as end-user, main contractor and sub-contractor and finally as an optical fiber enterpreneur.
