The NEXT response from the connector located at 2 m is well within the S- Bands and performs significantly better than the requirements. The NEXT in the cable is the source of the failure even though the cable’s NEXT response peaks are less than those of the connection. By knowing that the connection meets its performance requirement, the cable is easily identified as the
