“…Furthermore, for this type of PON, an arrayed waveguide grating (AWG), which adds lower power losses (typical insertion loss of 5 dB independent of the number of wavelengths), can be used instead of the power splitter. Figure 4 shows the architecture of a time division multiplexing PON (TDM-PON) and a wavelength division multiplexing (WDM) PON [25,26]. In both cases, the fiber plant from the OLT at a CO to the ONT at customer premise is completely passive.…”

Passive optical networks (PONs) are telecommunication networks that provide services to users by no active elements. Only passive elements are used in the network to transmit the information and signals between users as well as between users and the companies operating the telecommunication networks.PONhave evolved from their infancy as fine and economical ideas, toward a long‐term, reliable, and cost‐effective technical solutions for providing access to most users to high‐speed Internet by Fiber‐to‐the‐Home (and similar) solutions.PONare still evolving, providing the base of multiple standardized networks and in combination with different technologies are growing into metropolitan networks and extensions of mobile communications.Herein, we overview the state of the art of passive optical networks as well as their basic concepts. This work is divided into four sections: In Section 1, we give a summary of the main concepts of passive optical networks. Sections 2 and 3 introduce the most important features ofITU‐TRecommendations andIEEEStandards for passive access networks, respectively. Finally, Section 4 concludes the article with an overview on the future trends ofPONsfor access networks.

“…Local loops using optical fiber for access connections are called fiber-in-the loop systems [9][10][11][12]. Fiber access systems are also referred to as fiber-to-the-x (FTTx) system, where ''x'' can be ''home,'' "building", ''curb,'' ''premises,'' etc., depending on how deep in the field fiber is deployed or how close it is to the user.…”

“…A variety of architectures have been considered for this cost-sensitive application. 1 Most involve a passive optical network (PON), 2 which runs one feeder fiber from the central office to a passive terminal, then distributes the transmitted signals over distribution fibers to each of typically 16 to 32 optical network units (ONUs). The ONUs convert signals from optical to electrical at or near the home.…”
