Industrial Ethernet

Industrial Ethernet Connectivity

Originally, the Ethernet specification provided for the use of coaxial cables as the transfer medium. A distinction was made between thick coax (10BASE-5) and thin coax (10BASE-2), depending on the cable structure. Because of its low cost, thin coax was commonly referred to as “Cheaper net”. Today, the use of twisted-pair cable (10BASE-T, 100 BASE-TX) is more common. This type of cable represents a divergence from the original mechanisms in a number of ways. In twisted-pair cables, sending and receiving channels are separated. The channels are then transferred over a wire pair. The lines are organized according to categories. Within the industry, use of Fast Ethernet with a data transfer rate of 100 Mbit/s is widespread. The required cable must meet Category-5 standards. To improve network expansion capability and increase data transfer rates, fiber-optic cables are also used as transfer medium (10BASE-F, 100BASE-FX, and 1000BASE-X).
