Ethernet copper cable
Notice!
In order to comply with the strict rules regarding compliance to high energy voltage surges on
the Ethernet connections it is mandatory to use shielded twisted pair cabling (F/UTP), not
ordinary unshielded twisted pair cabling (UTP). F/UTP denotes foiled/unshielded twisted pair
and consists of four unshielded twisted pairs encased in an overall foil shield. This is not to
be confused with an S/FTP (screened / foiled twisted pair) cable which has four individually
shielded twisted pairs encased in an overall braided shield.
