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...

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...

Passive optical networks (PONs) will be the pervasive choice in the design of next-generation access networks. One possible solution to implementing passive optical access networks is to rely on wavelength-division multiplexing (WDM). Here we investigate the problem of providing real-time service to both hard and soft real-time messages in conjunction with a conventional best-effort service in ...

The optical access is gaining more interest as the demand for higher and higher bandwidth is getting stronger. The major drivers for larger bandwidth are the increasing processing power of user terminals and development of services that require substantially larger bandwidth than available in present day access networks. The prevailing access techniques, such as the digital subscribes line syst...

In the present paper, we have planned the deployment of passive, active and splitting optical devices employed in passive optical network (PON) standards such as giga-passive optical networks (GPON), broadband passive optical network (BPON) and Ethernet passive optical network (EPON) has been modeled and investigated over wide range of the affecting parameters. The utilization of the transport ...

The hybrid (Optical-Wireless broadband) network with the backbone as optical networks, Passive Optical Networks (PON), and wireless access networks have been proposed to provide good Quality of service (QoS). A Dynamic network solution for adopting both wired and wireless networking methods need to be updated. A Multicast based network coding technique is introduced for improving total network ...

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...
