OEO trace
Only one couple of OE and EO traces is displayed, corresponding to one wavelength.
If the measurement has been performed on different wavelengths, select
on the key
direction keys.
Functions such as Zoom/Shift, Cursors, Evt, Curve/Table, Full scale... are all the
same as for OTDR but the table result as well as the use of markers are specific
to OEO measurements.

Bi-directional measurement results use principles described in
measurement" on page
The total loss of the fiber (on the line specifying the total number of events) is resulting
from the average between the total loss calculated in the direction O->E and the total
loss calculated in the other direction.
Three tables are available in the OEO curve page, each showing attenuation, slope and
reflectance.
