  12. Home Page • M200 start-up page • If user hits Back/home key successively, they will get to this screen after exiting other screens • Allows access to File Manager for reviewing Traces on the M200 and managing the files and folders

  13. Home Page Test Modes • Full Auto, Live or Expert Test Mode is selectable from the Home Page using • buttons • Fiber Type (shown as Single-mode) is not selectable from the home page

  14. Home Page Launch & Receive 1 Launch & 2 Receive cables are specified in the test set up Launch cable only specified in the test set up 1 2 1 Fiber Ring Launch/Receive

  15. Home Page Next Tests • Name for next test: • SMITH HALL 001 • Fiber Number of the next test, can be incremented from 001 to 999 using the buttons • File Storage: as shown next tests will be stored to Compact Flash (CF) in the folder named SPG

  16. Main Menu TEST SETTINGS

  17. Test Settings: Main Menu -Test Tab Access Main Menu by pressing at the Home Page Test is the first Tab in all test modes Full Auto Live Expert Auto Expert Manual

  18. Test Settings: Sub Menus Parameters followed by “…” indicate there is a submenu. To access, highlight the parameter and press select the button Fiber Type: Use default setting or refer to manufacturers fiber specifications for the fiber under test

  19. Test Settings: Main Menu - File Tab Use to create a New Folder or to Change the Folder into which the Next Test Traces will be saved. • Highlight Folder… • Press the button to open the File Manager • Use and buttons to choose an existing file • Or Press Tools, use the down arrow to select New Folder to create a new folder Tools Pop up menu

  20. File Name Format Name Format – user selectable [Cable_Fiber] or [Far_Fiber] SMITH HALL_001_S13.sor Wavelength indicator- added by M200 Fiber number –user set, will auto increment File name prefix – user defined

  21. Test Settings: Main Menu - General Tab • Distance Units: select the units to be used for distance measurements: • Meters, Kft, Km, Miles, Feet • Beeper: Audible tone On or Off • Language:Select English or other available language. OTDR must restart to make current • View Version: Important for calls to Tech Support or for upgrading the M200

  22. Test Settings: Full Auto Mode • Select the Mode by using • Full Auto, Live, Expert • Select the Test Port type by using • Single-mode or Multimode • Specify if using Launch &/or Receive cables, and their respective length • Full Auto tests will be performed at two wavelengths per test: • 850/1300nm for Multimode • 1310/1550nm for Single-mode Main Menu Test Tab

  23. Test Settings: Live Mode With the Mode line highlighted use the buttons to select Live • Specify a Range: 1.5 to 2 x length of fiber under test • Live tests will be performed at ONLY one wavelength per test: • 850 or 1300nm for Multimode • 1310 or 1550nm for Single-mode • Specify if using Launch &/or Receive cables, and their respective length

  24. Test Settings: Expert Mode Auto Highlight the Mode line and use the buttons to select Expert Expert Auto uses default settings to perform a test but allows the user to test at a single wavelength if desired Expert Auto tests can be performed at one or two wavelengths per test: • 850 and/or 1300nm for Multimode • 1310 and/or 1550nm for Single-mode

  25. Test Settings: Expert Mode-Manual With the Mode line highlighted use the buttons to select Expert In Expert Manual the user must know information about the fiber under test and how to set up an OTDR Expert Manual tests can be performed at one or two wavelengths per test: • 850 and/or 1300nm for Multimode • 1310 and/or 1550nm for Single-mode

  26. Test Settings: Expert Mode - Manual Use buttons to specify the parameters for testing • Range: set to 1.5 to 2 x length of fiber under test including launch/receive cables • Pulse: (see next slides) • Narrow pulses are best for resolving close events but are limited to short links. • Wide pulses are good for measuring long links • Time (Averages): (see next slides) • Traces are always averaged over hundreds or thousands of pulses. • The trade-off is time vs. trace quality. • After about 3 min, you get very little additional improvement • Filter: selectable as On or Off, • Smoothes choppy traces. • As a rule of thumb use with PW 1us or greater

  27. Range Too short: less than link length Good: about 1.5x to 2x link length Too long: much larger than link length Link Link Link Trace is “squashed” into left side of display Can’t see entire link – unpredictable results Good trace – can see end of fiber

  28. Too narrow: Pulse Width About right: Too wide: Link Link Link Where is this this event? Trace “disappears” into noise floor Events can be seen and trace is smooth Can’t resolve events

  29. Too few: Averages (Time) About right: Too many Link Link Link Trace is noisy – noise floor is too high Trace is smooth Trace is smooth but waste of time

  30. Main Menu: Expert - Events Tab • Events: set to Auto or Off • Thresholds: set to Default or User • Auto Default will generate an Event Table using the M200 settings • Off will not automatically generate an Event Table

  31. Main Menu: Expert - Events Tab • Events: set to Auto • ThresholdsUser • Press Select and adjust the parameters using the navigation buttons • Auto User will generate an Event Table using the users threshold parameter settings

  32. Testing • Clean all connectors to be involved in testing • Connect Launch Cable to the appropriate Test Port and the Fiber Under Test • If using connect Receive Cable to far end of Fiber Under Test • Set the OTDR up as previously explained • Press Test

  33. Trace View Tab Displays the: • OTDR Trace graphically • Trace set-up parameters • A and B cursor locations • Distance from A to B cursors in user selected distance units • Insertion Loss measured from the A to B cursor 1 Launch Cable 2 3 5 4

  34. Trace View Tab (cont.) 1. Single-mode 2. Dual Wavelength 1310/1550nm 3. 150m Launch Cable 4. Trace is not yet saved 5. As shown traces will be saved: To the Compact Flash in the SPG folder as file: QA Box 001_S13.sor & QA Box 001_S15.sor 4 5 2 Launch Cable 3 1
