As I have understood Cat5E FTP (STP) cables support up to 1000mbps transmission rate. But I have seen them in stores that describe them of being capable of only 155mbps trx. Do both kinds exist? Or 1000mbps is only theoretical description? (given respective network hardware supports 1000mpbs communication)
Regarding '155mpbs': http://www.tlc-direct.co.uk/Products/CACAT5slashFTP.html
1I edited your question to say UTP (Unshielded Twisted Pair) instead of FTP (File Transfer Protocol). There's no such thing as an "FTP cable". – Spiff – 2014-02-24T18:07:31.023
@Spiff FTP in cabling means Foiled twisted pair, where shield is foil. – astralmaster – 2014-02-24T18:21:34.530
@Spiff also referred to as STP (shielded twisted pair) – astralmaster – 2014-02-24T18:22:05.563
Can you post a picture or link to the cables you saw? My bet is that it's just a typo or confusion on the part of the manufacturer or whoever made the label and they meant 155 MHz. – David Schwartz – 2014-02-24T18:38:45.267
Yep, check my original post – astralmaster – 2014-02-24T18:40:14.713
I stand corrected about the "there's no such thing as an 'FTP cable'", but the Question was still betrayed a misconception as written, because Cat5e is a UTP spec, not an FTP or STP spec. Vendors building Cat5e cable and adding a foil to it are creating some kind of nonstandard/proprietary in-between grade. – Spiff – 2014-02-24T19:13:00.953
