Network support - CAT 5e cable will support 10/100/1000 Ethernet. That is, Ethernet, Fast Ethernet and Gigabit Ethernet. CAT 5e Cable is completely backwards compatible, and can be used in any application in which you would normally use CAT 5 cable.

Less cross talk - Cross talk is the electrical interference that results when one wire's signal effects another wire's signal. CAT 5e cable has been improved over CAT 5 cable in this respect, and cross talk has been greatly reduced.

Bandwidth - This is directly related to network support, in the sense that the bandwidth is the information-carrying capacity of a system. The greater the bandwidth, the greater the information-carrying capacity in a given period of time. CAT 5e cable is rated at 350 megahertz, and it is this increased bandwidth (compared to CAT 5 cable) that allows it to support Gigabit Ethernet.

Almost all new installations are being done with CAT 5e - the improved signal carrying capacity of the cable is the primary reason.

CAT 5e Cable also has improved durability, due to improvements in the quality and thickness of the PVC protective jacket. It is more than suitable for most data cabling requirements.
