The image above shows a CAT6a U/FTP cable. Each pair has a foil sheath to protect them from the effects of
EMI and from crosstalk which may be induced by the signals carried on other pairs. Also present is a drain
wire, this is a conductive strip which runs along the entirety of the cable run. The drain should be connected to
the shield of the termination points at each end of a cable run providing a ground path for any unwanted signals.
The final example above is of a CAT6a S/FTP cable. The only difference from the previous example is the
addition of a braided shield within the outer PVC shield surrounding all four pairs. This provides a further barrier
to any EMI. This braided shield should be connected to the shield at the termination points.
