IEEE 802.3

IEEE 802.3 is a frame format which is the result of a merger of the specification IEEE 802.2 and IEEE 802.3, and consists of an IEEE 802.3 header and trailer and a header which the IEEE 802.3 IEEE 802.2 defines the physical layer and media access control sublayer of the data-link layer of the Ethernet standard wired
Here are some examples of standard IEEE 802.3 (Ethernet):
• Speed ​​10Base2 10Mbps, baseband technology, cable lengths up to 185 meters.Known as thinnet and can support up to 3 hosts in a single cable segment. Using a bus topology, both physically and logically with AUI connectors. Number 10 means 10 Mbps, base means using baseband technology, and the number 2 means the maximum distance of 200 meters before requiring a repeater. Network cards (NICs) using 10Base2 BNC connector (British Naval Connector / Bayonet Nut Connector / Bayonet Neill Concelman), and T-connector for connection to the network.
• Speed ​​10Base5 10Mbps, baseband technology, cable lengths up to approximately 500 meters. Known as Thicknet, using the topology of physical and logical bus with AUI connectors. Can reach 2500 meters with several repeaters and able to handle 1024 users for all segments.
• 10BaseT speed of 10Mbps, baseband technology, cable lengths up to 100 meters, using UTP cable category 3 (Cat 3). Unlike the 10Base2 and 10Base5, 10BaseT every device on the network must be connected through a hub or switch, and allowed only one Hub / Switch on each segment of cable. Using the RJ-45 connectors (8-pin modular connector) with a physical star topology and logical bus topology.
• 100BaseTX Speed ​​100Mbps, baseband technology, cable length 100 meters.Using 2 pairs of UTP cable with category 5, 5e or 6. There is only one host in a single cable segment, use an RJ-45 with a star topology (Star) physical and logical bus topology.
• Using 100BaseFX multimode fiber optic cable 62.5/125 micron size with a length of up to 412 meters. Using the ST or SC connectors with the topology of point-to-point.
• 1000BaseT speed of 1Gbps, using Category 5 UTP cable (Cat 5 and Cat 5E) 4 pair, with cable lengths up to 500 meters.
• Represents 1000BaseLX Singlemode fiber optic with a size of 9 microns and the signal emitted by laser 1300 nanometers. Can work with a distance of 30-10 kilometers.
