Book excerpt: This thesis combines the statistical analysis along with the deterministic electromagnetic theory to study both the Near-End Crosstalk (NEXT) and Far-End Crosstalk (FEXT) under geometric non-uniformities in cable binders. Further, a Thevenin equivalent based MTL method is extended from the Multi-conductor Transmission Line (MTL) theory to model crosstalk in a heterogeneous Digital Subscriber Line (DSL) system including a transition from a segment of optical fiber to twisted-pair copper lines. The proposed method based on the Thevenin representation is first developed and subsequently validated. Then the proposed method is employed for the characterization of crosstalk, incorporating geometric cable non-uniformities in the heterogeneous DSL system. Finally, the proposed method is compared with the conventionally used Power Sum Loss (PSL) model to illustrate its significant improvement in crosstalk estimation and hence its importance for Dynamic Spectrum Management (DSM) in the future heterogeneous DSL systems.
