ST style connector. The wavelength for this port is 1310nm and can be used for multimode or singlemode applications. Liquid Crystal Display (LCD) - When the MicrOTDR is first powered ON, the unit goes through a self- test, and all display segments, and annunciators are illuminated on power up. -
Page 11: Operation
OPERATION Cable length measurement with the MicrOTDR is simple; just plug your optical fiber or cable into the MicrOTDR's optical port connector on top of the unit, press and hold the MEASURE button, and read the distance in feet or meters. -
Page 12: Ior Selection
Select the IOR for the fiber optic cable you will be testing for a wavelength of 1300 nm (multimode) or 1310 nm (singlemode). Measurements Attach the fiber optic cable to the MicrOTDR's connector port. Depress and hold the MEASURE button until the Laser Active annunciator displays (typically 1.5 seconds), and then release the MEASURE button. - Page 13 Figure 5. This example shows that the distance to the EVENT is 31 meters. When the MicrOTDR detects multiple events, event number (1) will flash, and the MULTIPLE EVENT annunciator will be displayed. The distance to event number (1) will then be displayed, and the event number (1) will extinguish.
- Page 14 If event number (3) flashes, the distance to event (3) would be displayed. If event number (1) flashes, this means that the MicrOTDR has measured only two events, and the distance to event number (1) will be displayed again.
- Page 15 MicrOTDR User Manual Measurements (cont.) The MicrOTDR will measure the distance to the event. Refer to Figure 8 below. In this case, the distance to the end of the fiber cable (event) is 2242 meters. Figure 8 Page 13...

Page 19: Helpful Hints
NOTE: The distance to the first event and between events must be at least 30 meters. If any event is less than 30 meters, the MicrOTDR will not recognize that event. Refer to the example in Figure 10. In this example, there are four (4) events that the MicrOTDR will recognize and display. - Page 20 Helpful Hints (cont.) In the following example, there is an event that is less than 30 meters. The MicrOTDR will not recognize this particular event however; the MicrOTDR will recognize the subsequent events. Refer to Figure 11. In this example there will be three ( 3 ) events displayed.
