Page 13: Event Table
Luna 6225 Event Table The Event Table of the Luna 6200 software displays the return loss (RL) and insertion loss (IL) events detected in the Time Delay Domain and gives location, return loss, and insertion loss data for those events. -
Page 14: Turn Event Table Display On/Off
Luna 6225 Turn Event Table Display On/Off Event Table is displayed by default after you first open the application. Yet you have the option of not showing the Event Table (giving its display estate to the Delay Plot so that the plot can be shown on a larger area), which can be achieved by uncheck the “Events”... - Page 15 Luna 6225 Touching an individual event draws a marker at that event location. Touching the event again removes the marker. If you are using Single, or Vertical cursors, touching an Event table entry snaps the closest cursor to that event location.

Swept wavelength interferometry provides for a zero dead-zone, extremely high- resolution measurement of the light reflected (or transmitted) through the device under test (DUT).
- Page 29 Luna 6225 Figure 26 Fiber Optic Interferometer Network The tunable laser is configured to perform a linear sweep through a range of optical frequencies. Due to this linear sweep, any length differences between the reference and measurement paths of the interferometer will cause an interference pattern to appear at the detector. The interference frequency is proportional to the path length difference (time of flight) and the optical frequency tuning rate of the laser.
- Page 30 Luna 6225 Figure 29 Resulting interference pattern from two reflectors at different locations By taking a Fourier transform of this interference pattern, we can look at a plot which shows the reflected light vs optical time of flight (fiber length). The amplitude of each of these peaks is proportional to the amount of light reflected at any point in the fiber network.
- Page 31 Luna 6225 Measuring RL Each datapoint in the delay domain data represents the RL over a small length (<0.1mm). In order to characterize the RL for an entire event, the OBR software allows users to integrate the amplitude data over a user defined length. The integrated region will be shown in the delay domain plot as a highlighted region around the cursor(s).
- Page 32 Luna 6225 Measuring IL The OBR makes insertion loss measurements by comparing the return loss of the unaltered fiber on either side of an event in the delay domain data. The unaltered fiber reflects a small portion of light back to the instrument due to the process of Rayleigh scattering. This scattering is uniform over the length of standard telecom fibers and does not change in amplitude over time.
