" Information highway " may be the fiber optic communication, the system of a large number of users together with optical fiber cable. Based on optical fibers of the "information superhighway " has a wide frequency band, can transmit 500 channels simultaneously. Therefore, whether text information, audio information, or image information or TV, can timely delivery within the " information superhighway" network.
Ethernet CSMA/CD mechanism is adopted, carrier sense multiple access with collision detection. Gigabit Ethernet interface used in point-to-point line, no longer sharing bandwidth. Collision detection, carrier sense multiple access without any longer important. Similarities with the traditional maximum speed of Gigabit Ethernet Ethernet Ethernet frame structure is used within the same. Gigabit Ethernet and Gigabit Ethernet is similar, still retained the Ethernet frame structure. 10Gbit/s transmission speed through different coding methods or wavelength division multiplexing. So essentially, 10G Ethernet is a kind of Ethernet.
10G Ethernet in IEEE in 2002 July. 10G Ethernet, 10GBASE-R, 10GBASE-W and 10GBASE-X according to copper 10GBASE-T (adopted in 2006 ). 10GBASE-X uses a compact package, containing 1 simple WDM device, 4 receivers and 4 close to the wavelength of 1300nm laser at about 25nm interval work, each of the transmitter / receiver in 3.125Gbit/s speed ( data flow velocity is 2.5Gbit/s ) work. 10GBASE-R is a 64B/66B code ( not utilized in a Gigabit Ethernet 8B/10B ) serial interface, data flow is 10.000Gbit/s, therefore the clock rates are 10.3Gbit/s. 10GBASE-W is really a wide area network interface, compatible with SONET OC-192, the clock for the 9.953Gbit/s data stream is 9.585Gbit/s.
XENPAK is really a Multisource Agreement (MSA), instigated by Agilent Technologies and Agere Systems, that defines a fiber-optic or wired transceiver module which conforms to the 10 Gigabit Ethernet (10GbE) standard of the Institute of Electrical and Electronics Engineers (IEEE) 802.3 working group. The MSA group received input from both transceiver and equipment manufacturers throughout the definition process. XENPAK has been substituted with more compact devices providing the same functionality.
