Connection technology In Network

• ↞←Many technologies are available for wide area network links. Examples include circuit switched telephone lines, radio wave transmission, and optic fiber. New developments in technologies have successively increased transmission rates. In ca. 1960, a 110 bit/s (bits per second) line was normal on the edge
  
  of the WAN, while core links of 56 kbit/s to 64 kbit/s were considered fast. As of 2014, households are connected to the Internet with Dial-Up, ADSL, Cable, Wimax, 4G or fiber The speeds that people can currently use range from 28.8 Kilobits per second through a 28K modem over a telephone connection to speeds as high as 100 Gigabits per second over an Ethernet 100GBaseY connection.

• AT&T plans to start conducting trials in the year 2017 for businesses to use 400 Gigabit Ethernet.^[4] Researchers Robert Maher, Alex Alvarado, Domaniç Lavery & Polina Bayvel of University College London were able to increase networking speeds to 1.125 Terabits per second.^[5] Christos Santis, graduate student Scott Steger, Amnon Yariv, Martin and Eileen Summerfield developed a new laser that quadruples transfer speeds over fiber optic cabling.^[6] If you multiply 1.125 times 4 on your calculator (the amount of terabits per second achieved by
  
  University College of London researchers times the laser technology that quadruples transfer speeds over fiber optics developed by Caltech researchers) you get 4.5, and that means that with the two technologies combined that currently exist we could have 4.5 Terabit per second internet speeds available to the public sometime in the near future.
