I think that 100 Mhz cable doen't correspond to the 5e cathegory - it would be better to refer it to the 5 cathegory... and talking about 5e cathegory - you shuold remind that this type of the cable has 125 Mhz working frequency. I could be wrong. Check this please.
CAT5e is still 100MHz[Cat5 x Cat5E]. FastEthernet uses MLT-3 to scale down frequency, so even using 4B5B (which pumps 100Mbps up to 125Msymbols), the real working frequency is 31.25MHz.[100BASE-TX]Zekkerj (talk) 13:33, 5 June 2013 (UTC)
