Perspective Application of Passive Optical Network with Optimized Bus Topology
Passive optical networks (PONs) represent a promising solution for modern access telecommunication networks. These networks are able to meet the increasing demands on transmission rate for demanding multimedia services, while they can offer typical shared transmission speed of 1.25 or 2.5 Gbps. The major role in deploying optical distribution networks ODNs plays the maximum attenuable loss, whi...
متن کاملStudy of Orthogonal Modulation Schemes for Passive Optical Access Networks
In this thesis, the potential of upgrading Passive Optical Networks in order to increase available bandwidth and expand in services and number of users is studied. The upgrade is feasible through the adoption of orthogonal modulation techniques –used in other types of networksadapted adequately to the specific needs of a passive optical network. At first, it is investigated and recorded the sta...
متن کاملImplementation of Future Generation Agile Gigabits Passive Optical Network
This paper reviews the progress of the passive optical network, and discusses a viable means for the realisation of future generation agile gigabits passive optical networks, (GPONs) by the use of low cost narrow band tunable lasers and arrayed waveguide gratings (AWGs). It projectes a twostage strategy for the realisation of future generation agile GPONs, i.e., the near-term Time and Wavelengt...
متن کاملApplication of Fiber Ring for Protection of Passive Optical Infrastructure
Today, passive optical networks (PONs) are mostly used as modern high-speed access networks for various applications. However, there are also several specific applications, such as in business, office, army or science sector, which require a complex protection and backup system against failures and malfunctions. Typically, tree or star topologies are used for passive optical networks PONs. Thes...
متن کاملOverlapped-subcarrier Multiplexing for Hybrid Tdm\wdm Passive Optical Networks
An innovative overlapped-subcarrier multiplexing (O-SCM) technique is proposed for wavelengthdivision multiplexed (WDM) passive optical networks (PONs).Allowing a certain amount of spectral overlap between the uplink and the downlink maximizes the spectrum usage of bandwidth-limited reflective semiconductor optical amplifier (RSOA)-based optical network units (ONUs), while reducing the effect o...
متن کاملA Review on Passive Optical Network
In this paper, passive optical network and its techniques have been reviewed. Due to the property of high bandwidth and energy saving, Passive optical network can be a better solution for the networks accessed in future. Traffic pattern has evolved to video and image based services from voice and text oriented services in the access networks. For the support of symmetric, high-speed and perfect...
