TL;DR: In this article, a simulation model of coexisting GPON and NG-PON1 systems is presented, which has been developed for the analysis of feasibility and implementation issues of this coexistence.
Abstract: In this paper, the simulation model of coexisting GPON and NG-PON1 (10G-PON) systems is presented, which has been developed for the analysis of feasibility and implementation issues of this coexistence. The aim was to analyze the impact of the most important parameters of the components that are needed for new network elements, on the performance of these coexistent networks. On the basis of the results obtained, the optimal parameters of the new system components were defined.

TL;DR: Interferometic optical communications system can meet these requirements, in which the laser in the CPE is replaced by an interferometer for the outgoing voice channel, and part of the received optical power is converted to electrical power using photovoltaic cells and an energy storage device to drive the C PE.
Abstract: The plain old telephone service, POTS, still generates the largest proportion of public network operators' revenues. If optical communications systems are to compete with traditional twisted-pair copper systems in delivering telephony, they must achieve the same levels of cost and service availability, offer low-risk investment in optical fiber infrastructure, and satisfy the same regulatory requirements. Interferometic optical communications system can meet these requirements, in which the laser in the CPE is replaced by an interferometer for the outgoing voice channel, and part of the received optical power is converted to electrical power using photovoltaic cells and an energy storage device to drive the CPE. The reach of the system is similar to locally powered laser systems in the downstream direction, but back reflections and scattering can affect the upstream link if the communications and powering signals share the same path.

TL;DR: An optical customer premises network (CPN), called H-Bus, designed to interface future broadband ISDN signals and distribute available bandwidth to terminal equipment connected to the CPN, is discussed.
Abstract: An optical customer premises network (CPN), called H-Bus, designed to interface future broadband ISDN signals and distribute available bandwidth to terminal equipment connected to the CPN, is discussed. Key features of this network are the use of optical fiber as a transmission medium and a hybrid architecture, namely, a broadcast bus for the downstream (network interface to subscriber terminal) and a looped bus for the upstream (subscriber terminal to network interface) traffic. The physical layer of the network makes use of the synchronous optical network (SONET) transmission format. The user information is carried using the asynchronous transfer mode (ATM) technique. The reliability of H-Bus is improved through the use of a network component called an optical protection socket (OPS). This is an automatic optical bypass switch that protects the CPN in the case of individual node failures. To resolve any access contention on the upstream bus, a multipriority media access control protocol has been defined. Its performance is compared with that of protocols used in other high-speed local area networks. >

TL;DR: An effective energy consumption calculation method is proposed to compare the energy efficiency of the tree-topology 10 gigabit ethernet passive optical network (10G-EPON) and ring- topology time- and wavelength-division-multiplexed passive Optical network (TWDM-PON), two experimental networks deployed in China.
Abstract: Higher capacity and larger scales have always been the top targets for the evolution of optical access networks, driven by the ever-increasing demand from the end users. One thing that started to attract wide attention not long ago, but with at least equal importance as capacity and scale, is energy efficiency, a metric essential nowadays as human beings are confronted with severe environmental issues like global warming, air pollution, and so on. Here, different from the conventional energy consumption analysis of tree-topology networks, we propose an effective energy consumption calculation method to compare the energy efficiency of the tree-topology 10 gigabit ethernet passive optical network (10G-EPON) and ring-topology time- and wavelength-division-multiplexed passive optical network (TWDM-PON), two experimental networks deployed in China. Numerical results show that the ring-topology TWDM-PON networks with 2, 4, 8, and 16 wavelengths are more energy efficient than the tree-topology 10G-EPON, although 10G-EPON consumes less energy. Also, TWDM-PON with four wavelengths is the most energy-efficient network candidate and saves 58.7% more energy than 10G-EPON when fully loaded.
