Principles of Operation
The iOLM application uses the hardware of an EXFO OTDR to perform
acquisitions and characterize the various elements detected on the probed
link. However, while a regular OTDR takes one averaged trace at a time,
with one given set of test parameters, the iOLM takes a series of
measurements and integrates them into a simple and intuitive Link View.
The test parameters for each sub-measurement are determined by smart
algorithms during the measurement. Just as each link is different, each
iOLM measurement is different, with its own set of test parameters
according to the link length, loss, and ORL. Test time varies depending on
the link tested, but is mostly influenced by total link loss. The application
uses information from all sub-measurements to enhance the
characterization of each element found on the link, yielding accurate and
complete results. Depending on the module configuration, you can
perform a single or multiple-wavelength acquisition. In the latter case,
results will be provided for each wavelength, and a global pass/fail status
for each element is displayed.
The application summarizes the results in a linear representation of the
link, displaying each element with its associated position, loss and
reflectance, as well as the element type.
Exporting Data to Other Formats
The iOLM application can generate report in various formats and allow
batch post-processing of the measurement. The test configuration files can
be created from FastReporter and imported on each test unit.
