Definition of "passive optical network" |
Passive Optical Network is a system that brings optical fiber cabling and signals all or most of the way to the end user. Depending on where the PON terminates, the system can be described as fiber-to-the-curb, fiber-to-the-building, or fiber-to-the-home. / A passive optical network (PON) is a telecommunications network that uses point-to-multipoint fiber to the premises in which unpowered optical splitters are used to enable a single optical fiber to serve multiple premises. A PON consists of an optical line terminal (OLT) at the service provider's central office and a number of optical network units (ONUs) near end users. A PON reduces the amount of fiber and central office equipment required compared with point-to-point architectures. A passive optical network is a form of fiber-optic access network. / A cost-effective, high-speed interconnection between terminals and host computers in a private branch exchange environment. / a network where the optical fiber plays the role of a broadband, passive interconnect, and the functions of switching and control are made using electronics. |
