What are FTP cables' main shielding designs and how do they tackle electromagnetic interference?

Q: What are FTP cables' main shielding designs and how do they tackle electromagnetic interference?   A: FTP cables use specialized shielding to reduce signal disruption:   F/UTP: Overall foil screen over unscreened pairs, balancing basic EMI protection and flexibility.   S/FTP: Foil + braided dual shielding for enhanced EMI attenuation and mechanical strength.   F/FTP: Individual pair foil + overall foil screen, minimizing crosstalk between channels.   U/FTP: Individual pair shielding without overall screen, prioritizing installation flexibility.   These designs let network engineers choose based on EMI levels, bandwidth needs, and physical constraints for reliable data transmission.
