Category 3 is voice grade cable and can only beused in Ethernet networks (10BASE-T) to transmit data at speeds of upto 10 Mbps. Category 5One of five grades of Twisted Pair (TP) cabling defined by theEIA/TIA-586 standard. Category 5 can be used in Ethernet (10BASE-T)and Fast Ethernet networks (100BASE-TX) and can transmit data atspeeds of up to 100 Mbps. Category 5 cabling is better to use fornetwork cabling than Category 3, because it supports both Ethernet(10 Mbps) and Fast Ethernet (100 Mbps) speeds.3Com recommends that you use Category 5 cable — the maximumsegment length for this type of cable is 100 m (328 ft).
