Above all else, CAT5e upholds Gigabit Ethernet (1000BASE-T).    The transmission capacity of the CAT5 link is just 100 MHz, while the transfer speed of a CAT5e link is 350 MHz. With this higher data transfer capacity that Gigabit Ethernet (1000BASE-T) can be conveyed by CAT5e links. The CAT5e link is completely in reverse viable with CAT5 and can be utilized in any application in which you would regularly utilize the CAT5 link.
