PON (Passive Optical Network)
Note: Many topics at this site are reduced versions of the text in "The Encyclopedia of Networking and Telecommunications." Search results will not be as extensive as a search of the book's CD-ROM.
PON is one solution to the lack of bandwidth in the so-called "last mile" or "first mile" as some like to refer to it. Home users have limited choices for gaining fast access to the Internet (telephone or cable systems). Likewise, enterprises have been limited to carrier T1 and T3 offerings, although wireless, optical, and satellite services are now more viable. PON provides another solution in metropolitan areas. It is being used in FTTH (Fiber to the Home). A hybrid PON system extends fiber cable to carrier remote terminals and then takes advantage of DSL services over the copper wire into homes.
