AGUAS-MARTINEZ, Elkin Fabián; PUERTO-LEGUIZAMON, Gustavo Adolfo  and  SUAREZ-FAJARDO, Carlos Arturo. Dynamic WDM-TDM access networks featuring wired-wireless convergence. Antioquia [online]. 2016, n.78, pp.99-104. ISSN 0120-6230.

Growth in the use of devices with Internet access and migration of telecommunications to Internet Protocol (IP) technology has made the bandwidth demanded by users appear for the first time as a limited resource. Optical fiber is demonstrating to be the solution to this issue based on the capability to provide enough bandwidth to manage large volumes of data at high speed featuring low loss transmission. Passive Optical Networks (PON) are presented as an alternative with respect to conventional copper-based access networks due to the use of distribution passive elements, which have a lower maintenance cost as compared to the active counterpart. In addition, the optical fiber capacity provides a future-proof platform to support the forthcoming bandwidth requested in the access segment. This paper presents and demonstrates through practical and simulation data analysis a proposal for next generation PON based on Time Division Multiplexing (TDM) and Wavelength Division Multiplexing (WDM). Complying with a typical PON power budget, the architecture envisages dynamic wavelength allocation and converged transport of wired and wireless services on a unified optical platform architecture.

Keywords : Capacity upgrade; convergence; dynamic architecture; passive optical network.
