1. 1. Analysis of the performance of Hybrid TWDM Passive OpticalNetworks (NG-PON2)

   Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

   Författare :Rameez Ahmed Khan; [2021]
   Nyckelord :Next Generation Passive Optical Networks NG-PONS ; Time Division Multiplexing TDM ; Wavelength Division Multiplexing WDM ; Hybrid Passive Optical Networks; Time and Wavelength Division Passive Optical Networks TWDM PON ;

   Sammanfattning : In this study, a review of research literature has been carried out to investigate Hybrid Time and wavelength Division Multiplexing techniques with respect to reach, split ratio, and speed of the network. This was done to overcome challenges presented by Passive Optical Networks, such as the reach and the high split ratio. LÄS MER

3. 2. Hardware-Efficient WDM/SDM Network : Smart Resource Allocation with SDN Controller

   Master-uppsats, KTH/Kommunikationssystem, CoS

   Författare :Lida Liu; [2019]
   Nyckelord :WDM; SDM; SDN; routing and wavelength assignment; large-scale network; hardware resource; WDM; SDM; SDN; routing och tilldelning av våglängd; storskaligt nätverk; hårdvara resurs;

   Sammanfattning : Optical networking has been developing for decades and wavelength-division multiplexing (WDM) is the main technology used to carry signals in fiber-optical communication systems. However, its development has slowed because it is approaching the Shannon limit of nonlinear fiber transmission. LÄS MER

4. 3. Dynamic Optical Resource Allocation in Transport Networks Based on Mobile Traffic Patterns

   Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Författare :Epameinondas Kontothanasis; [2017]
   Nyckelord :;

   Sammanfattning : Mobile traffic increases rapidly. Based on Ericsson’s forecast [1], mobile traffic is expected to grow at a compound annual growth rate on percentage of 45% as the number of smartphone subscriptions and the consumption per subscriber increase. The monthly data traffic volume is expected to grow 6 times between 2015 and 2021. LÄS MER

5. 4. Embedded Communication Channel for Node Communication in WDM Networks

   Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Författare :Anders Rosén; [2015]
   Nyckelord :Embedded Communication Channel; NE-to-NE communication; ECC-Driver; Socket programming; Linux kernel;

   Sammanfattning : Optical Transport Network is a set of Optical Network Elements (NE) connected by optical fiber links able to provide support for optical networking using Wavelength-Division Multiplexing (WDM). In order to be able to introduce link-level applications that require NE-to-NE communication in a packet-optical network, an embedded communication channel is needed. LÄS MER

7. 5. Study on Fault Detection andLocalization for Wave length Division Multiplexing Passive Optical Network

   Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Författare :Sunil Poudel; [2013]
   Nyckelord :Wavelength division multiplexing passive optical network WDM-PON ; open access;

   Sammanfattning : Wavelength division multiplexing passive optical network (WDM-PON) can meet growing bandwidth demand in access network by providing high bandwidth to the end users. Failure in the access network is becoming critical as a large volume of traffic might be affected. LÄS MER
