C, LC, SC, STThe Ethernet physical layer is the physical layer component of the Ethernet family of computer network standards which defines the electrical or optical properties of the physical connection between a device and the network or between network devices. It is complemented by the MAC layer and the logical link layer which provide features like framing, addressing, checksums, virtual LANs, and link aggregation. The Ethernet physical layer has evolved over its existence starting in 1. The speed ranges from 1 Mbits to 1. Gbits, while the physical medium can range from bulky coaxial cable to twisted pair and optical fiber. In general, network protocol stack software will work similarly on all physical layers. Gigabit Ethernet was already used in both enterprise and carrier networks by 2. Gbits12 and 1. Gigabit Ethernet3 ratified. Higher speeds are under development. Many Ethernet adapters and switch ports support multiple speeds, using autonegotiation to set the speed and duplex for the best values supported by both connected devices. While this can practically be relied on for ports supporting twisted pair cabling, only few optical fiber ports support multiple speeds. If auto negotiation fails, some multiple speed devices sense the speed used by their partner,6 but will assume half duplex. A 1. 01. 00 Ethernet port supports 1. BASE T and 1. 00. BASE TX. A 1. 01.

For 1. 0 Mbits, no encoding is indicated as all variants use Manchester code. Most twisted pair layers use unique encoding, so most often just T is used. The following sections provide a brief summary of official Ethernet media types section numbers from the IEEE 8. In addition to these official standards, many vendors have implemented proprietary media types for various reasonsoften to support longer distances over fiber optic cabling. Early implementationseditEarly Ethernet standards used Manchester coding so that the signal was self clocking and not adversely affected by high pass filters. Name. Standard ClauseCommon connectors. Description. Coaxial cable. Xerox experimental Ethernet. Proprietary. The original 2. Mbits Ethernet implementation had eight bit addresses and other differences in frame format and was carried on 5. BASE5. 80. 2. 3 8AUI, vampire tap. Original standard uses a single coaxial cable into which you literally tap a connection by drilling into the cable to connect to the core and screen.
