Methods are provided for reducing port to port crosstalk on a multiport assembly. Steps of the method include placing at least one BEMI in at least one compensation region, disposed on a PCB.

The PCB includes a plurality of ports, at least including adjacent first and second ports, each of which is an RJ45 jack port. Each port of the plurality of ports includes a plurality of modular insert pins, and is associated with an IDC pin group.
