8.8 Construction Mode
Chapter 8 OTDR Operation
Construction Mode is useful when a large number of fibers need to be tested with the same settings at multiple
wavelengths. This mode tests a fiber at two wavelengths, saves the traces and displays them in dual trace
mode.
Create or Open a Project
Press the menu button, use the right or left buttons to highlight the Project Management folder icon and press
select. Use the up and down buttons to highlight the desire project and press Select, or create a new project
once you have established all the desired parameters for testing. Create the new project by pressing the Menu
button and with File tab highlighted press the down button. Press select with New highlighted and use the
onboard QWERTY keyboard to enter the project name and touch save.
Note
Refer to Chapter 9 of this manual for detailed project management operating procedures.
To enter project details, touch the Details section at the bottom of the projects screen. A dialog will be
displayed that allows the user to set the Customer, Date, Operator along with 'to and from' locations if desired.
Touch Close at the bottom of the dialog to go back to the projects screen
With the project enter and highlighted, press the Select button. This will open the file management screen.
Set Base File Name
Once the project folder has been created and or opened, the files folder for that project will be displayed. A
base file name for the test should be established. Press the menu button to open the file management menu,
with the file tab highlighted, press the select button or the down button to open the drop-down menu. With
save highlighted press the Select button. Use the QWERTY to enter a base file name.
When testing in construction mode, files will be save in numeric order with the first two digits of the wavelength
added to the end of the file name. For example, if the base file name of SAMPLE is entered, the first test in
construction mode (If the test were at 1310/1550nm) would be a test at 1310nm with a name of SAMPLE.1.13
and the second test would be the same fiber at 1550nm with a name of SAMPLE.1.15. The next tests would
be SAMPLE.2.13 and SAMPLE.2.15,..... If a fiber number other than one was to be tested, the base file
name should have a .X added. For example, if the test was to start at fiber 15, the base file name should
be SAMPLE.14. When the construction mode test is completed, the files saved will be SAMPLE.15.13 and
SAMPLE.15.15.
After selecting save ensure that project name is moved to the center blue highlighted are of the project list and
press select to set that project as active and to use the parameters set with that project.
Once the base file name is set, exit the file manager by pressing the menu button, pressing select on the file
tab, using the down button to highlight exit and pressing select.
