1. Dynamic Optical Resource Allocation in Transport Networks Based on Mobile Traffic Patterns
Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)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
2. Study on Fault Detection andLocalization for Wave length Division Multiplexing Passive Optical Network
Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)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
3. Optical Time Domain Reflectometer based Wavelength Division Multiplexing Passive Optical Network Monitoring
Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)Sammanfattning : This project focuses on wavelength division multiplexing passive optical network (WDM-PON) supervision using optical time domain reflectometer (OTDR) for detection and localization of any fault occurred in optical distribution network. The objective is to investigate the impact of OTDR monitoring signal on the data transmission in the WDM-PON based on wavelength re-use system, where the same wavelength is assigned for both upstream and downstream to each end user.

4. Study on Supervision of Wavelength Division Multiplexing Passive Optical Network systems
Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)Sammanfattning : The wavelength-division-multiplexed passive optical network (WDM-PON) offers many advantages such as large bandwidth per user, easy management, high network security and low insertion loss enabling long-reach and/or high split-ratio. However, with the rapid development and growing interest for deployment of WDM-PON, the PON systems are becoming increasingly vulnerable to various failures. LÄS MER
