Fiber optic and Ethernet What is the difference

Fiber optic network
"Information superhighway" is based on optical fiber communication, it uses fiber optic cable to ten million user units linked together. Fiber-based "information superhighway" has a wide frequency band, can transfer 500 TV channels. Therefore, whether text, audio, or image information or TV, can be in the "information superhighway" transmission network in a timely manner. Transmission rate is high, an "Encyclopaedia Britannica" through "information superhighway", less than 5 seconds to transfer is completed. The total length of the cable has reached 1.2808 million U.S. thousands of meters, but with the "information superhighway" compared to the requirements, transmission capacity is not enough. In true "information superhighway" before the appearance of these cable systems must compatibilizer, and the transmission of digital information, and will have to be identified, so as to power and telephone communications systems to accurately pass the user. Engineers working on fiber and copper which can provide families with practical communication lines, debate issues. The problem is bandwidth, the higher the transmission frequency used, the greater the bandwidth. Coaxial cable can transmit 75 channels of general programs, therefore, coaxial cable is the "information superhighway" of wire extending into the millions of households.

Ethernet Ethernet

Ethernet is a network of low-level protocol, usually in the OSI model physical layer and data link layer operations. It is the most common bus protocol, the data rate of 10Mbps (megabits / sec) of the coaxial cable system. The system is relatively cheap and easy to install, direct use of each workstation on the network adapter BNC-T connector, you can connect the cable from one workstation to another workstation, complete the network control tasks. Ethernet (Ethernet) LAN is a computer networking technology. IEEE established the IEEE 802.3 standard Ethernet technology standards are given. It provides the connection, including the physical layer, medium access layer signal and the content of the agreement. Ethernet is currently the most popular LAN technology. It has largely replaced other LAN standards such as Token Ring, FDDI, and ARCNET. Ethernet standard topology of the bus topology, but the current Fast Ethernet (100BASE-T, 1000BASE-T standard) to reduce to the greatest degree of conflict, the greatest increase network speed and efficiency, the use of switches (Switch ) to connect to the network and organization, so that Ethernet became a star topology, but logically, Ethernet still uses a bus topology and CSMA / CD (Carrier Sense Multiple Access / Collision Derect that conflict with Detection Carrier Sense Multiple Access) technology, the bus contention.
