Carriers have very strict guidelines when it comes to validating the fiber and coax install in DAS ,Small and WIFI systems.
Line Sweep testing and PIM are very different tests. Both are very important and accurate measures of a cell site’s ability to provide service and perform optimally.
Line sweeping measures the signal losses and reflections of the transmission system.
PIM testing is a measure of construction quality and poor quality will result in self-interference.
ODTR Testing: An Optical Time Domain Reflectometer (OTDR) testing is important and instrument used by carriers to certify the performance of new fiber optics links and detect problems with existing fiber links.
