Optimization of the Optical Power Budget for Various WDM-PON Network Designs with Traffic Protection Securing

For the expansion of WDM-PON networks, it is necessary to have a detailed knowledge of the optical power budget in all its parts. This contribution shortly analyses various WDM-PON network designs with the traffic protection securing utilized only passive optical components in remote nodes. A main part is focused on the optimization of optical power budget possibilities for considered WDM-PON network designs. For evaluation of optical power budgets, a simulation model related to WDM-PON network designs and to interactions between various metropolitan and access parts in the optical distribution network is realized in the Matlab programming environment.
