Read full descriptionHide full description
This application serves as a mobile client for EXFO RFTM, an optical fiber test and monitoring solution using an intelligent OTDR which you can operate on premises or through the EXFO cloud server. The EXFO RFTM solution is designed to build, turn up, and monitor any type of fiber network, including point-to-point and PON links. This mobile application is the field extension of EXFO RFTM. It is used by field technicians and engineers to execute various tests from an OTDR unit installed in a fixed and central location. Testing supports running end-to-end loss tests on PONs in an FTTP context and runs the remote OTDR in tone mode on the selected route for fiber identification, even in live fiber conditions. Field technicians can also use the app to fully characterize the distribution fibers connecting a main hub or cabinet to premises from the remote iOLM test unit.
