Abstract
Nowadays there is a rapid increase in the subscriber’s requirements of high speed broadband services which in consequence translated to an increase in the volume of generated traffic in our communication networks. That made the service providers to adopt many techniques to upgrade their networks to achieve this goal. In the same time there is a huge increase in the network’s capacity; which pushes to increase the current network’s capabilities to overcome these urgent issues. In this thesis, these problems were investigated deeply to get the reasonable solutions for such cases. Two models are provided; the first is five channels hybrid DWDM/CWDM fiber to the home optical network with bit rate of 20 Gb/s which is dedicated to provide a reliable solution to the bit rate and the increase of network subscribers number. The second model can be considered as an extended reach FTTH network, which is provided to make the network capable to exceed the boarders to achieve further distances than the current one; by increasing the fiber link length. After that, there were different studies that investigated the possibility to implement the promising technique of ultra-dense wavelength division multiplexing (UDWDM), and an optimization of the fiber link length with the transmitter power.
