“…The recent variants of DSL technologies are very high speed digital subscriber line (VDSL2) and vectored VDSL (V-VDSL2). The operating frequency of both these technologies ranges up to 30 MHz [2,3] with a data rate of up to several hundred Mbps. The latest proposed and standardized DSL technology is G.fast [3,4], which aims to provide speeds exceeding 1 Gbps at a distance of 50 to 250 m over the copper twisted pair.…”

“…The G.hn and G.fast [2,4] facilitate the coexistence of DSL and PLC and as the frequency bands used in both these technologies overlap the issue of electromagnetic compatibility (EMC) arises. The effect of PLC interference on DSL mainly depends on the line topology [3,10]. Topology estimation plays an important role in analyzing the impact of PLC on DSL interference.…”

Using the electricity infrastructure for broadband data transmission is known as power line communication (PLC). The quality of broadband connectivity over a power line is a strong function of the line topology. Two-step hybrid single-ended loop testing (SELT) to estimate the open port loop topology of power lines is discussed in this paper. Correlation time domain reflectometry (CTDR) at different sockets is used to construct the initial topology.Optimization-based frequency domain reflectometry (FDR) is employed to ascertain more accurate power line topology.The discussed method has the advantage of reusing the existing DSL modem for the measurement and no prior knowledge is needed for the topology estimation. This method is validated for a wide range of line topologies with different numbers of bridge taps. The performance of the estimated topology is calculated using two-port network theory and the influence of the bridge taps on the performance of the line is analyzed.

Newly available standards for broadband access using Digital Subscriber Lines (DSL) have a high degree of spectrum overlap with home networking technologies using broadband Power Line Communications (BB-PLC) and this overlap leads to Electromagnetic Compatibility issues that may cause performance degradation in DSL systems. This paper studies the characteristics of measured PLC-to-DSL interference and presents novel results on its statistical characterization. The frequency-dependent couplings between power line cables and twisted-pairs are estimated from measurements and a statistical model based on a mixture of two truncated Gaussian distributions is set forth. The proposed statistical model allows the accurate evaluation of the impact of BB-PLC interference on various DSL technologies, in terms of both average and worst-case impacts on data rate. This paper further provides an extensive assessment of the impact of PLC-to-DSL interference at various loop lengths and for multiple profiles of Very-high speed Digital Subscriber Lines 2 (VDSL2), Vectored VDSL2 (V-VDSL2), and G.fast. The results of this paper confirm that the impact of PLC interference varies with loop length and whether Vectoring is used or not. Furthermore, the average impact is found to be generally small but strong couplings can lead to substantial degradation of DSL.
