“…Therefore it can be concluded that the decrease in τ RC is most significantly caused by the copper conductor. It has been shown earlier that fields in an RC can couple into transmission lines and cables [18] [19]. The measurement shows that some of the reflected energy in the RC couples into the copper conductor.…”

“…The coupling of electromagnetic waves to transmission lines has been widely studied [11][12][13] in the case of a single plane wave and also recently in the case of a reverberant field [14][15][16]. In [7] we built on those ideas comparing a number of methods to compute the energy absorbed by PCB load tracks and their contribution to the PCB AACS.…”

Predicting the probability of susceptibility to electromagnetic interference for a system would be of significant interest to the EMC community. In this paper, we consider the coupling of electromagnetic energy into printed circuit board (PCB) traces and how it relates to the power balance model of shielding effectiveness. We show results of some measurements of the absorption cross-section of a load on a PCB trace and compare them with previously published results.

“…Since G.fast is the extended version of VDSL2 in which the bandwidth can go up to 106 MHz or 212 MHz, the crosstalk coupling in G.fast system is expected become the dominant interference at a higher frequency and for longer transmission distance over the unshielded twisted-pair copper cables [15]. Crosstalk coupling can be reduced by increasing the number of twist per meter [16].…”

An ultrafast digital subscriber line (DSL) technology called G.fast is important for ultrafast broadband Internet access services. In G.fast, the existing cable bundles installed for 250 m from the distribution point to the customer’s premises are used to support the gigabit data transmission (aggregated 1 Gbit/s) for frequency up to 106 MHz or 212 MHz. Since unshielded cable is used, and the frequency is 12 times higher compared to the very high-speed DSL2 (VDSL2), it is important to investigate the cable performance in terms of insertion loss and crosstalk coupling. In this paper, the impact of cable twisting rate on 10 pairs of unshielded twisted-pair copper cables for a small copper bundle on insertion loss and crosstalk coupling is investigated. A simulation model is developed based on the standard cable installed in Malaysia. The model reliability is validated by comparing the obtained result with the published result in the literature. Besides, the twisting rate of 100 m cable is manipulated by changing its lay size to determine its impact on insertion loss and crosstalk coupling. The results showed that a high twisting rate can reduce the far-end crosstalk but increase both the insertion loss and near-end crosstalk.
