Abstract:Telecommunication networks are divided into core, metropolitan and access networks. The core and metropolitan networks use high capacity bandwidth optical fibers, while the access networks have bandwidth bottlenecks because of the use of twisted-pair wires and coaxial cable. To solve this problem and to offers the users broadband access at low cost the use of passive optical networks (PON) is proposed. A PON is formed by two basic elements, the optical network unit (ONU), positioned close to the customers and … Show more
