Abstract
The present invention relates to RJ45 modular inserts that are connected to a printed circuit board used to transfer high speed signals for telecommunication interface media connections. The printed circuit board is configured to reduce near-end cross-talk (“NEXT”) without compromising impedance. NEXT is substantially reduced by utilizing a low reactance dielectric insert with a two-stage combination positive and negative compensation removal technique. By utilizing this method, the pair-to-pair NEXT is substantially reduced and differential pair impedance are controlled in a simple and cost effective manner.
