Abstract
Methods and systems for compensating for crosstalk in a telecommunications jack are disclosed. One method includes manufacturing a circuit board having a zone of crosstalk compensation between a first wire pair and a second wire pair, the zone of crosstalk compensation including a capacitive coupling connected between the first wire pair and the second wire pair and a second capacitive coupling selectively connectable in parallel with the capacitive coupling. The method further includes determining a crosstalk value generated by the jack including the manufactured circuit board. The method also includes, upon determining that the crosstalk value is outside of a crosstalk pass band, adjusting the zone of crosstalk compensation by altering an electrical connection between the second capacitive coupling and the capacitive coupling after the circuit board has been manufactured.
