Ethernet in physical layer deals with the standardization of connector used for interconnecting devices. EIA/TIA (Electronic Industries Alliance / Telecommucations Industry Association) is the authority that creates the physical layer specifications of Ethernet.
When designing a network we have to know about IEEE specifications and their distance limitations. Some of important IEEE standard’s

| 10BASE2 | Thinnet (Coax) | 10 Mbps | 185 m |
| 10BASE5 | Thicknet (Coax) | 10 Mbps | 500 m |
| 10BASE-T | Cat3 (or higher) | 10 Mbps | 100 m |
| 100BASE-FX | MMF | 100 Mbps | 2 km |
