A fiber-based access system to customer premises — for the delivery of video services such as video-on-demand — that allows multiplexed traffic to be distributed to a number of users in such a fashion as to limit the number of optical terminations required.
Passive Optical Networking
Passive Optical Network. An optical transmission system that carries signals from Central Office (CO) to the termination point (e.g. customer premises in FTTP case) over fiber optic cable. It's called passive because once signal leaves the CO, it runs through fiber optic distribution network by means of connecting and splitting without active components or powered electronics. At the fiber optic termination point, the optical signal is converted back to electrical signal by an ONU (Optical Network Unit) or ONT (Optical Network Terminal). Also see FTTP, APON, BPON, EPON, and GPON.
An abbreviation for passive optical network. Learn more about PON...
A high bandwidth, point-to-multipoint optical fiber network based on ATM, Ethernet or TDM. In this type of optical network, wavelengths of light are divided into timeslots so that each wavelength can be shared by a number of users. With PONs, a single fiber from the carrierâ€(tm)s exchange can service 16, 32 or more buildings through the use of both passive devices to split the optical signal, and PON protocols to control the sending and transmission of signals across the shared access facility.
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 (FTTC), fiber-to-the-building (FTTB) or fiber-to-the-home (FTTH).
Passive Optical Network. A fibre-based network which uses passive splitters to deliver signals to multiple users.
A fiber-based network built without active electronics. Because a PON uses optical splitters rather than costly active electronics, it is less expensive to build and maintain than a network that uses active electronics. PONs are still more expensive than copper-based networks. A PON is usually used in a local loop to connect customers to the central office. BPON (Broadband Passive Optical Network) is a broadband PON.
(Passive Optical Network) - The usual acronym for a fiber based transmission network containing no active electronics.
A network in which one access line is shared among multiple buildings. Optical splitters and couplers are used at each fiber connection in the network.
Abbreviation for passive optical network. A broadband fiber optic access network that uses a means of sharing fiber to the home without running individual fiber optic lines from an exchange point, telco Central Office (CO), or a CATV headend and the subscriber's home.
