Why need different cable media for cabling?
There are different cables may affect the speed and distance of networking. For example: CAT 5 UTP cable: Four pairs wrapped in a thermal plastic insulator, twisted around one another and encased in a flame-retardant polymer Maximum operating frequency: 100 MHz; suitable for token ring, Ethernet, fast Ethernet, gigabit Ethernet (after mid-1998), and 155-Mbit/s ATM. CAT 5e UTP cable: Same as Cat 5, but the manufacturing process is refined and the cable is of a higher grade. Maximum operating frequency: Up to 200 MHz; suitable for token ring, Ethernet, fast Ethernet, gigabit Ethernet (after mid-1998), and 155-Mbit/s ATM. CAT 6 SFTP cable: Four pairs wrapped in foil insulators and twisted around one another; an extra insulating shield; and a flame-retardant polymer jacket. Maximum operating frequency: 600 MHz; suitable for Ethernet, fast Ethernet, gigabit Ethernet (after mid-1998), and 155-Mbit/s ATM. Multimode fiber: Glass cable that transmits data as pulses of light.
