Category 5e (CAT-5e) cabling is the accepted minimum standard for connecting computers, Ethernet switches and network devices including telephones together. It provides a maximum speed of 100Mbps and a maximum bandwidth of 100MHz over a distance of 100 metres. As an alternative to plugging PCs directly into Ethernet switches, CAT-5e structured cabling provides an easier, neater and more flexible option for network and telecoms management.
Category 6 (Cat6) cables are primarily used for networks looking to run faster than Cat5e. It delivers a max speed of 10,000Mbps and a max bandwidth of 250MHz over 55 metres. A Cat6 cable is composed of four pairs of wires, similar to Cat5 cable. The primary difference between the two is that, Cat6 makes full use of all four pairs. This is why Cat6 can support communications at more than twice the speed of Cat5e.
