This class is designed to assist managers in understanding the complexities of understanding an OTDR trace. OTDRs can provide valuable information about loss and location of faults, but only if the person interrupting the results understands how to read the data. The trace can show you the power loss but does not provide the source of such loss. Analysis of the trace is complicated since there are multiple causes to a loss. It’s important to realize that the OTDR can only provide accurate measurements and proper interpretations if the OTDR is setup correctly.
