Have you heard of IEEE 802.3? It has a long history and has to do with our topic today, Ethernet.

Ethernet is a communication standard that was developed in the early ’80s to network computers and other devices in a local environment such as a home or a building.

This local environment is defined as a LAN (Local Area Network) and it connects multiple devices so that they can create, store and share information with others in the location.

Ethernet is a wired system that started with using coaxial cable and has successfully progressed to now using twisted pair copper wiring and fiber optic wiring.

Let’s break for a trivia question. Who invented twisted pair wiring?
Alexander Graham Bell invented twisted pair wiring in 1881.

In 1983, Ethernet was standardized into the standard IEEE 802.3 by the Institute of Electrical and Electronic Engineers (IEEE).

This standard defined the physical layer and the MAC (media access control) portion of the data link layer of wired Ethernet.
These two layers are defined as the first two layers in the OSI (Open Systems Interconnection) model
The “physical” layer consists of the following components: Cabling and Devices.

First, let’s take a look at Ethernet Cabling;
As stated previously, Ethernet cables come as coaxial cable, which is not very common except in older installations, twisted pair, and fiber optic.

The most common cable is twisted pair cables, with the latest being Category 6 with speeds up to 1 Gbps and Cat6a and Cat 7 with speeds up to 10 Gbps.

Category 5 and 5e cables are both still used in many existing applications but handle the lower speeds between 10 Mbps to 100 Mbps but are more susceptible to noise.

The Ethernet twisted pair utilizes RJ-45 eight-pin connectors at either end of the cable that is pinned for transmitting and receiving data in either half or full-duplex mode.

      Hi,
      If by BSC you mean "Base Station Controllers" which is a telecommunication and wireless mobile networks subject, then I can refer you to this helpful document by Fujitsu; http://www.fujitsu.com/downloads/TEL/fnc/whitepapers/Fujitsu_Wireless_Backhaul.pdf

      You know, computer scientists are used to handle the magical "Ether", the 5th element, as a physical substance through which electromagnetic energy must travel. The Ethernet, Ethereum, etc. It allows us to connect to a network.

      Excuse me realpars. You are right cat5 cables are rated for 10 to 100 Mbps BUT cat5e can handle 1gigabit. And you also are right about cat5/5e being susceptible to interference.

      Hi, Thank you for your information. I have confusion about Profinet, EtherCAT, Sercos...Do they use Ethernet as physical layer? And only change the protocol?

      RealPars In reply to Phúc Vũ

      Hi there, thank you for your comment.

      EtherCAT and Profinet are both an "Ethernet Protocol" with some differences.
      For instance, EtherCAT uses the same "physical" and "data link" layers as Ethernet but the protocols deviate from there. The purpose of developing such protocols is the particular advantages of them in different applications. Actually, Ethernet is not a practical solution for many industrial applications as it routes frames of data to and from a "vast" number of separate addresses, individually.

      So in cases, where the data may be something as simple as a single register to obtain a real-time analog reading, it seems more reasonable to take advantage of other types of Ethernet protocols such as EtherCAT to reduce the data traffic, increase the speed and so on.

      By the way, we are going to make a video regarding "EtherCAT" in the near future. It could be a good reference for you to grasp more vivid data regarding EtherCAT and its differences from Ethernet.

      Thanks
