Next Generation xDSL system is envisioned to provide net-bidirectional data rate of up to 1Gbps as recommended by ITU-T in G.9700 and G.9701 with high bandwidth that is larger than 100MHz. In a multi-pair cable, crosstalk among twisted pairs is the dominant impairment that is generated due to the capacitive and inductive coupling among the twisted pairs. Crosstalk associated with the xDSL network is near-end crosstalk (NEXT) and far-end crosstalk (FEXT). Data rate is mainly limited by Far-End-Crosstalk (FEXT) and mitigate through vectoring within a same vectored group. NEXT on other hand is avoided by Frequency Division Duplex (FDD) for upstream and downstream transmission. Data rate could be doubled if full bandwidth is available for simultaneous upstream and downstream transmission through effective NEXT cancellation.
