Cat5e (Category 5 enhanced)
The frequency used (100MHz) and the manufacturing process of Cat5e are the same as Cat5.
They are pretty much the same in the way their wires are arranged.
The main difference between Cat5 and Cat5e is in the specification.
Cat5e is a variant of the Cat5 specification, which aims to reduce the amount of cross talk (interference between wire pairs).
Cat5e can provide faster transfer rates, from 1000 Mbps and up to 1Gbps (Gigabit Ethernet).
Another advantage is that Cat5e can be more flexible, so you can bend it to fit it in smaller spaces.
Today, some of the new Cat5 cables may meet up with the Cat5e specifications, but they are not certified to be a 5e cable
