4 Reference Procedures Loopback Reference Procedure for Two Way Measurements NOTE: Light Source/Two Way/ ORL port must use a connector with APC polish NOTE: For two or one direction testing involving two instruments, referencing should be independently performed on both Loss Test Sets. The following will set reference at all wavelengths: Clean and inspect patch cables and testing ports before connecting any cables. Connect the Light Source /Two Way /ORL port to the Power Meter port of the same instrument using the proper patch cable. Select [POWER], Press [Autotest], then press [Abs/Rel] and then press [Set Ref] for 3 seconds. Meters will display BUSY and then 0.00 db R. Loopback Reference Side By Side Reference for Two Way Testing Referencing is performed on one of the instruments, which will set reference at all wavelengths on both Loss Test Sets: Connect the Light Source /Two Way /ORL ports of the instruments. Select [POWER], [Autotest] ], [Abs/Rel] and press [Set Ref] for 3 seconds. Meters will display BUSY and then 0.00 db R. Side by Side Reference for Two Way Testing 4

5 Reference Procedures Continued Side by Side Reference for Single Direction Testing Connect the Light Source/Two Way/ORL port to the power meter of the second instrument. Select [POWER] on both instruments On Light source, Press [Auto test] On Power meter, press [Abs/Rel] and [Set Ref] for 3 seconds. Meter will briefly display BUSY and then 0.00 db R. NOTE: Two patch cables can be used for the reference if required for current testing application. Side By Side Reference for Single Direction Testing Measurement Procedures TWO WAY LOSS AND ORL IN AUTOTEST This method requires a matched pair of Two Way Loss Test Sets, which will perform automated bidirectional testing and wavelength detection by data exchange between the instruments. After Two Way Loss Test Sets have been referenced: Exit Autotest on both instruments. Connect the Fiber Under Test (FUT) to the patch cables connected to the Two Way ports Press [Autotest] on one of the instruments Both instruments now show the same two way average loss in db R and display rotates through all available source wavelengths. 5

6 Two Way Test Measurements Continued Both units also display A B. A will be flashing on the unit where Autotest was initiated, and it has become the A unit. The other unit will flash B, and it has become the B unit. This only indicated which unit is A and B not the direction of test results being displayed. To step through all measurements on locked wavelength, press [ ] button on the hidden keypad. Results are displayed in this order: average bi-directional loss loss from A to B: A B loss from B to A: A B ORL at A end ORL at B end When displaying loss in one direction, the reference value will be shown on the left. Alternatively, selecting [Abs / Rel] displays the actual measured dbm value and source nominal output power. To determine what direction the test result is being displayed in look for the change between the A and B icons when you press the [ ] on the hidden key pad. ORL measurement from A to B ORL measurement from B to A IL measurement average A to B and B to A IL measurement one direction B to A Reference Shown - Indicates 1 direction measurement 6

7 One Way Test Measurements ONE WAY LOSS IN AUTOTEST This method is applicable for loss measurements where data communication is one way only. Testing on one fiber can be achieved with: Single Two Way Loss Test Set Two instruments used as a combination of Light source and Power meter Perform Side by Side Reference for single direction testing. Two patch cables may be used if required for testing application. Connect to the Fiber Under Test (FUT), loss will be automatically displayed. Use [-/+] to show one wavelength only. To exit Autotest, remove test lead for more than 8 seconds or turn off source Memory Functions Data can be stored in all modes, however, memory recall and cancel functions are not available in Autotest and only work in Light Source, Power Meter or Return Loss modes. Clear all memory: press both [MR] and [Exit] simultaneously for 3 seconds. clr will display. To save in next available location, press [M+]. To change next store location, press [ ] [-/+] [Set] or [Menu]. To recall, press [MR] and [-/+] to scroll memory. Use [Abs / Rel] to see db/dbm values. Hold down [Abs/ Rel] to see reference level. For data recorded in Autotest, press [-/+] to view measurements at all source wavelengths. For each wavelength, to step through all available Two Way Loss and ORL Autotest measurements, select [MR], [-/+] and then press [ ] repeatedly. Two way test only: press [ ] repeatedly to scroll details. To exit memory display, press [Menu]. 7

8 Transferring Saved Data Data transfer between the KI 7347 and Kits external software package must be completed using the USB to RS 232 cable. Install KITS software from CD provided with the Test Set or go to Once KITS program has been loaded on the computer open the program. KITS program will display the welcome screen with option for setting up the report. Note that several report options are available. For Bi- Directional Testing we will select Loss Testing and Meter Dump. Uncheck all other worksheets. Uncheck Data Logging and Meter Reading Select Setup to additional reporting criteria which must be determined. If unit is not connected to the computer this screen will appear. Connect the meter to the computer using the USB to RS 232 cable and press Connect. Once unit has been connected press Setup to continue with report setup. 8

9 This menu will allow you to select the parameters for testing as well as the report build. Be sure to confirm your Test Directions are set properly including ORL Tests at A and B locations. Otherwise this data will not be transferred. Reference End may be different depending on the reference style chosen. Confirm Wavelength for both Source and Test the press the Green Arrow. Complete the necessary data including connector type, cable length ( be sure to convert to feet or miles), splices and connectors. Confirm the number of fibers to test including what fiber to start at. This example is fiber 19. Pass/Fail standards can be compared against International or Custom. Example has established custom standards. 9

10 Now the computer should display the Live Data Worksheet without test results. To import results from the meter select Add-ins to access the KITS menu. Next Select Test Data and then Memory Download to start loading results from the machine. Once activating the memory download be sure to indicate where to start memory download from, how many results or fibers to be downloaded, wavelengths to be downloaded and what fiber ID to start at. This example has fiber 19 saved in the memory as 19. Which makes both circled values identical. 10

11 The Final Report Final report will populate with the values downloaded from the machine. This example shows failing results based on the Pass/Fail criteria the user established in previous menus. In this case Insertion Loss was excessive on all fibers at 1310 and one fiber/wavelength failed the ORL test. Certain items such as Statistical Analysis can be hidden to make the report smaller.
