Connector for communication systems with cancelled crosstalk

A connector for communications systems, comprising:

• first, second, third and fourth primary terminals arranged in a first ordered array with said second and third primary terminals being immediately adjacent each other and between said first and fourth primary terminals, said first and fourth primary terminals being respectively coupled to sources of equal and opposite signals, said second and third primary terminals being respectively coupled to sources of equal and opposite signals;
• first, second, third and fourth secondary terminals arranged in a second ordered array;
• and
• printed wiring board means for electrically coupling said first, second, third and fourth primary terminals to said first, second, third and fourth secondary terminals, respectively, said board means including a dielectric substrate having first, second, third and fourth conductive paths printed thereon connecting and connected to said first, second, third and fourth terminals, respectively, sections of said first and third paths being in relatively close proximity and being spaced and separated by said dielectric substrate to provide a first capacitive coupling therebetween through said dielectric substrate, sections of said second and fourth paths being in relatively close proximity and spaced and separated by said dielectric substrate to provide a second capacitive coupling therebetween through said dielectric substrate;
• said conductive paths having length and widths and being relatively spaced on said substrate, and said substrate having a dielectric constant such that any induced crosstalk in said primary terminals is approximately canceled.
