Passive Optical Network architecture has become a cost effective way to meet performance demands in access networks. Optical fibre is shared by many subscribers in a generic metropolitan network known as FTTx, often displacing the ubiquitous copper lines. Passive Optical Network fiber-optic technology has developed to connect whole communities over these shared optical networks with fast but cost effective and reliable service.
