Page 26: Construction Mode
Close at the bottom of the dialog to go back to the projects screen With the project enter and in the highlighted position, touch it to 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. Pull the file management menu down, touch file and then save. Use the on-screen keyboard 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, etc. 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. Once the base file name is set, exit the file manager by pulling down the file menu, touch the file tab, and touching exit.

Page 28: Loss Measurements
The active cursor will snap to the position touched on the screen or fine adjustments may be made using the left or right triple chevron indicators in the scale bar just below the trace. Loss Measurements 2 Point loss 2 Point loss measurements take into account the difference in vertical height between where the A and B cursors cross the fiber trace. This information is located on the main OTDR screen in the A-B section of the trace information as shown in Fig. 8.2. This is a quick method of checking the loss between any two points on a fiber optic link. dB/km The dB/Km (dB/Kft or dB/Mi) loss method takes the 2 Point loss in dB and divides by the distance between the cursors in Km (Kilometers), Kf (Kilofeet) or Mi (Miles). For accurate dB/..loss measurements, the two cursors must be on level backscatter points at least 100m apart. (NA will show for distances that are not sufficient for measurement). Optical Return Loss This Optical Return Loss (ORL) is separate from the event ORL (Reflectance) that is displayed in the event analysis under the TYPE header for an individual event. The measurement displayed in the loss measurement area of the main OTDR screen and in the L (Link) row in the TYPE column is an optical return loss based on the entire link. It is the total accumulated light reflected back to the source along the fiber optic link. FTE-7100 OTDR User's Guide Rev A 1/2019... -
Page 29: Basic Splice Loss
There will be four vertical dashed lines on the display. To set point number one, touch and hold the stylus on the first splice loss point. Drag point number one to the desired location. Continue with the remaining splice loss points. See Fig. 8.6 for proper positioning of splice loss points. To close the splice loss adjustment screen, touch in an open area of the display well away from the cursors. Note It is necessary to set these areas in clear backscatter to acquire the most accurate measurements; they must not include other events. FTE-7100 OTDR User's Guide Rev A 1/2019... - Page 30 The vertical green line is used to show which point of the LSA measurement areas is the focus of the left and right buttons. To move to the next point, press the Select button. FTE-7100 OTDR User's Guide Rev A 1/2019...

Page 32: Enter Event Analysis
If a 1.00dB splice/event loss is acceptable, set the threshold to 1.00. If a splice loss of 1.00 is the fail point, set the threshold to 0.99 ORL: If a system ORL of -35.dB reflectance is acceptable, set the threshold to 35. If -35dB is the fail point, set the threshold to 35.1. Refl: If a -45dB, event reflection is acceptable, set the threshold to 45. If -45db link loss is the fail point, set the threshold to 45.1. Link: If a 20dB, link loss is acceptable, set the threshold to 20. If 20db link loss is the fail point, set the threshold to 19.5. EOF: If an event loss of 3dB, should trigger the end of fiber, set this to 3.0 if the end of fiber should be anything greater than 3 dB loss, set it to 3.1.

This is the value used to determine if the fiber link passes or fails it's link threshold. dB/Km or Kf or Mi: dB per Kilometer if in KM and DB/KF if in Kilo-Feet and DB/MI if in mile unit of measure. This is the calculated loss per Km, Kf or Mi from the end of the dead zone of the previous event to the beginning of the current event. The value in the "L" line of the table for this column is the dB Per/KM, Kf or Mi for the total link. TYPE: Event Type lists Splc for non-reflective events and displays a reflectance value for reflective events. The "E" end event is marked End and the "L" event displays the System ORL.
