摘要： Embodiments of the present invention relate to an arrangement for analyzing transmission line properties. Measurement data providing means provide data of a first frequency dependent line property, line property calculation arrangement with model handling means, a Hubert transform handler and line property determination means calculate said first property based on model parameters, line resistance at 0 frequency, roc, a cut-off frequency, v, a line capacitance C∞ and a line inductance L∞H. The line model handling means calculates the line inductance L(f) via a Hubert transform of a function of Q(f/v), wherein the function Q(f/v) relates the line resistance R(f) to roc as R(f)=roc·Q(f/v). The Hilbert transform values are calculated using a parameterized closed form expression for the Hubert transform or they are tabulated. The line property determination means calculates the first property and criteria function application means uses the measured first property and the calculated first property for model parameters to find optimized numerical model parameter values.

摘要： Embodiments of the present invention relate to an arrangement for analyzing transmission line properties. Measurement data providing means provide data of a first frequency dependent line property, line property calculation arrangement with model handling means, a Hubert transform handler and line property determination means calculate said first property based on model parameters, line resistance at 0 frequency, roc r cut-off frequency, v, line capacitance C∞r and line inductance Σ̂. The line model handling means calculates the line inductance L(J) via a Hubert transform of Q(f/v)r relating line resistance R(J) to roc such as formula (I). The Hilbert transform values are calculated using a parameterized closed form expression for the Hubert transform or they are tabulated. The line property determination means calculates the first property and criteria function application means uses the measured first property and the calculated first property for model parameters to find optimized numerical model parameter values.

摘要： A Passive Optical Network, PON, comprising an Optical Line Termination, OLT, connected to one or more Optical Network Terminals, ONT, over an Optical Distribution Network, ODN, is monitored by a monitoring device. The monitoring device comprises an Optical Frequency Domain Reflectometer, OFDR, and is arranged to monitor the optical power received by the OLT and the ONTs of the PON, and to perform transceiver analysis of the OLT and the ONTs, combined with an OFDR analysis of the ODN, based on the monitored optical power violating a threshold.
