    Setups Setup Change Procedure The following exercise shows you how to change setups. The process is easy: use a combination of the button and arrow keys. Setups may be viewed or changed during a test in progress. If the Fiber Scan, Test Range, Pulsewidth, or Averages setup is changed during a test in progress, it becomes effective when the next test is started (push the button again).
  • Page 38 Setups A setup field in mid screen that lists all the setups in a menu. The currently selected setup is highlighted. A change bar at bottom screen showing the currently selected setup parameter and options. An arrow that indicates more options may show on either end of the change bar.
  • Page 39 Setups Choose the Fiber Scan: IntelliTrace parameter to continue. IntelliTrace is the most commonly used test mode, and is used throughout this manual for the various exercises. Step 5. Continue to use the arrow keys as described in steps 3 and 4 to change other setups in the Test Setup menu as needed for your application.

  • Page 42 Setups Fiber Scan The Fiber scan setup specifies the test mode of the instrument. Fiber Scan selections are: IntelliTrace Manual, and End of Fiber. IntelliTrace. IntelliTrace mode automatically locates and measures all events on a fiber. It is the easiest and most commonly used test mode, and is the factory default.
  • Page 43 Setups Test Range Test Range specifies the maximum fiber distance over which test data is acquired. To avoid ghosting, the test range should be set to a little longer than the full length of the fiber. Test Range depends upon laser wavelength selected. When switching between laser wavelengths (on dual-wavelength instruments), the Test Range parameter automatically changes to accommodate the laser currently selected.
  • Page 44 Setups Pulsewidth and Test Range setups are interdependent. Test Range parameters are displayed with the Pulsewidth parameters. If you change the pulsewidth, and the current test range is incompatible, the closest compatible test range is automatically selected. Factory default depends on the Fiber Scan setup and the wavelength selected.
  • Page 45 Setups Splice Threshold Splice Threshold specifies the threshold level (in dB) used in marking splices. Splice events that have a loss equal to or greater than the threshold are indicated with an asterisk (*). Selections are 0.02 to 5.00 dB for both singlemode and multimode, in 0.01 dB steps.
  • Page 46 Setups Scan For Scan For specifies whether to display all events or only events equal to or greater than the user-set splice and reflectance threshold levels. Only those events that are scanned for are displayed on the screen. An asterisk (*) marks the splice loss or reflectance measurements that are equal to or greater than the threshold.
  • Page 47 Setups Refractive Index Refractive index is the ratio between the speed of light in a vacuum to speed of light in a fiber. Refractive index varies from fiber to fiber and is an important setup for achieving accurate test results. A change in the refractive index affects the distance scale on the screen and fiber measurements.
  • Page 48 Setups Scattering Coefficient The scattering coefficient represents the amount of backscatter reflected by a particular fiber. The scattering coefficient is not required, but if you know the coefficient of your test fiber, you can use it to maximize reflectance-measurement accuracy. The scattering coefficient is a characteristic of the fiber under test and, similar to the refractive index, can vary from fiber to fiber.
  • Page 49 Setups Distance Units Distance Units specifies measurements to be displayed on the screen in meters, feet, or miles. Factory default is meters. Distance is displayed on the horizontal scale under the waveform, numerically at the top of each cursor, and in the event table columns. Distance Units is user settable in all modes.

    Cleaning Cleaning the Connector Adapter Step 1. Blow through each end of the connector adapter barrel with dust-free canned air (see Figure 4–3). Step 2. Dampen a lint-free pipe cleaner with electronics-grade alcohol. The pipe cleaner absorbent should be about 0.35 cm (0.15 inch) in diameter, and the wire part of the pipe cleaner should be less than 0.1 cm (0.04 inch) in diameter.
