Types of Shielded CableIBM TYPE 1: Traditional 150 Ohm cable includes twisted pairs wrapped in foil and completed
with a metal braid around all conductors and then wrapped with an insulator. However there are a number of negatives about this type of cable:
CAT-6e FTP: Foil Twisted Pair provided in 100 Ohm with 4 twisted pairs surrounded by a metallized foil wrapper. The
pluses and minuses are:
+ Less rigid… almost as flexible as traditional UTP + Easily connectorized + Can be specified to support 10GBASE-T
– Requires careful shield attention during connectorization – Requires careful ground management to prevent loops
Advantages of CAT 6e Bulk Cable and Category 6e Assemblies CAT 6e FTP: Foil Twisted Pair provided in 100 Ohm with 4 twisted pairs surrounded by a metallized foil wrapper.
+ Less rigid… almost as flexible as traditional UTP + Enhanced Shield termination makes it easily connectorized
+ Enhanced Shield termination provides isolation between devices + Enhanced Shield termination eliminates "ground loops" + With FTP, alien next can be reduced to almost zero
+ With FTP, RJ-45 and field termination can be used
