ONT reflection for additional maintenance by OTDR-measurements in FTTH networks

ONT-reflection is used, additionally to GPON-EMS, to identify termination points in FTTH-PON-networks. OTN-reflectivity vs. wavelength is investigated. In-service OTDR-measurements from Central Office allow testing PON-branches and to distinguish optical length differences down to 2m.
