The term FTP stands for foil twisted pairs. FTP networking cables often support Ethernet LAN. The cables are designed and constructed with a twisted pair or multiple twisted pairs of cores with an overall foil tape shield wound around the assembly.
Aaaaah ok, thanx for that.

No thats the SFTP where the individual pairs are shielded, STP as per that definition is standard shielded where all the pairs are sheathed in a shield.

Shielding the actual pairs would likely be a much thicker cable as that would raise the interferance in the pairs itself. Thats the only reason to shield the individual pairs: internal interferance in the cable.

Shielded cables are usefull when running cable in "noisy" electrical environments. Just don't be a @ss and run it in the power trunks to compensate.
FTP: With FTP cables, each twisted pair of cables is wrapped in a shielding of foil to protect the cable from EMI and crosstalk.

Well... I believe the ISO/IEC 11801:200 definition is:

UTP: Unshielded twisted pair
F/UTP (also FTP): Foil around all pairs, individual pairs are unshielded
S/UTP: Braiding around all pairs, individual pairs are unshielded
SF/UTP: Braiding and foil around all pairs, individual pairs are unshielded
S/FTP: Braiding around all pairs, individual pairs have foil around them
F/FTP: Foil around all pairs, individual pairs have foil around them.
U/FTP: No overall shielding but foil around individual pairs.

Good. Now with all that sorted out the only question that remain is which supplier have stock have stock in Durban or Jhb.

That looks like (the pic on that page, that is) U/FTP
Their description says "Overall foiled (ALU/PET) Central cross for improved geometry and performance"... which seems to indicate foil around all pairs as well which would be F/FTP. In case anyone is being pedantic.

*EDIT*
It is indeed F/FTP according to this (same product code):


This is FTP:
