Passive optical network

A passive optical network ( PON ) is a system that brings optical fiber cabling and signals all or most of the way to the end user. Optical Access Networks. Physical Layer and Devices. Fiber optics uses light signals to transmit data. There are two important types of systems that make fiber-to-the-home broadband connections possible.

These are active optical networks and passive optical.

Invited Presentation at. This presentation is available on-line at. Passive fiber access architectures (GPON) optimize the FTTH business model by leveraging the high subscriber density allowed by passive splits – as high as users per PON or OLT port. Much fewer OLTs are required as a single OLT module can support hundreds of homes. EPON and GPON are popular versions of passive optical networks (PONs).

These short-haul networks of fiber-optical cable are used for Internet access, voice over Internet protocol (VoIP), and digital TV delivery in metropolitan areas. Other uses include backhaul connections for cellular basestations, Wi-Fi . The steady increase in the demand for broadband services and the consequent increase in the volume of generated traffic in our communication networks have motivated the need to implement next generation networks in our territories. GPON is the highest spee longest life, lowest cost.

Its main characteristic is the use of passive splitters in the fiber distribution network, enabling one single feeding fiber from the provider to serve multiple homes and small businesses. Several key technology decisions await the NG-EPON Study Group: (1) number of wavelengths, (2) bit rate per wavelength, (3) transceiver tunability, and (4) . A PON is a telecommunications network that transmits data over fiber optic lines. PONs are used by ISPs and NSPs as a cost-effective way to provide . The underlying machinery of a PON system decides the up-streaming and down- streaming bandwidth and capacity. An asynchronous passive optical network ( APON) has an electrical layer based on cell-switching technology. APON is also sometimes referred to as broadband passive optical network (BPON).

A very basic, animated explanation of PON operation. It connects to the core switch using traditional Ethernet pluggables. PON has been around for many years in the service provider space.

Does fiber to the home or the triple play ring a bell? Now PON is finally making its way into the enterprise space with opportunities for customers deploying new infrastructure or new construction. The technology is catching . MYTHBUSTERS: The Honest Facts About. Passive optical network (PON) technologies have become an important broadband access technology as a result of the growing demand for bandwidth- hungry video-on-demand applications. Abstract: The provision of both wireless and wired services in the optical access domain will be an important function for future passive optical networks (PON).

With the emergence of 5th generation (5G) mobile communications, a move toward a dense deployment of small cell antenna sites, in conjunction . Needs for providing security to end users have brought installation of quantum key distribution (QKD) in one-to-many access networks such as passive optical networks. In the networks, a presence of optical power splitters makes issues for secure key rate more important.

However, researches for QKD in access networks . This high-spee real-time facility enables delivery of the craved-for next-generation, high-capacity broadband .
