The term Cat 5e refers to the Category 5 Enhanced cabling standard for networks. Cat 5e cables are often utilised within Ethernet infrastructures to support 10BASE-T (Ethernet), full duplex 100BASE-TX (Fast Ethernet), and 1000BASE-T (Gigabit Ethernet) networks. Cat 5e technology provides a performance of up to 100 MHz. The Cat 5e cable standard shares similarities with the earlier generation Cat 5. Both of these cable categories contain twisted pairs of copper wire for transmitting signals. Their bandwidth is also the same. The difference between the Category 5 cable and Category 5 Enhanced cable is in performance specifications. The Cat 5e twisted pair technology meets stricter specifications regarding factors such as crosstalk (signal interference between lines) and loss of signal strength.
Cat 5e Cabling for Networks
The Cat 5e network cabling standard is backward compatible with the original Cat 5 and Cat 3 standards. Patch cables that connect network devices will be labelled according to their Categories, such as CAT5 or CAT5e Ethernet cables. Category 5 cabling is also used in telephone and video applications. Cat 5 and 5e network cables have a maximum 100-metre run length. If an installation requires a longer cable run, a switch or a repeater will be needed.
Cat 5 Cable is Widely Implemented
Though Category 6 cables have been developed, the enhanced Cat 5 cable continues to be a highly popular choice for wired LAN and telephone connections. It is available in stranded or solid formats. Compared to Category 5 Enhanced cabling, today’s fibre optic cables provide higher bandwidth with reduced interference. However, CAT 5e cables are more affordable than fibre optic.
