detect cable fault (open or short) and report the estimated fault location.
Moreover, VCT can also detect PHY type (100M, 1000M or 10000M) as
well as estimated cable length of normal cable. Cable length estimation
only supports Giga speed mode.
Just select a port number and click . Test result shall be displayed
accordingly.
