Is NEXT due to installation?

NEXT, or Near-End Crosstalk, is interference in electrical circuits, especially in telecom and networking cables, where a signal on one wire pair creates an unwanted signal on a nearby pair.
Proper termination, which involves ending a cable with a connector that matches its impedance, is essential to minimize signal reflections and maintain signal integrity. When termination is done incorrectly, it can cause reflections that increase crosstalk, including NEXT.
So, ensuring proper termination helps reduce this interference and keeps your signals clear and efficient.
