Techno-economic feasibility studies for Solar powered Passive Optical Network

The presented paper is a techno-economic feasibility study to use solar energy as a renewable energy to power the Passive Optical Network (PON). This discussion focuses on the requirements and sources of power for the active components of optical access networks. To ensure continuous reduction of the carbon footprint while advancing towards purely passive optical networks, we have emphasized the need for alternative, renewable and greener sources to supply the required power. Solar power would be used as the default power source while mains are used as backup or a standby source. This is because solar power can be harvested and stored with less carbon footprint.
