The broadband loop project is a joint European project which is developing low cost access network solutions for competitive access providers. The project is developing passive optical network (PON) solutions optimized for delivery of services in low penetrated areas. The basic version of the PON is a SDH PON which can provide managed SDH transport to the customers premises. ATM can be provided via the SDH PON system. The PON bandwidth can be gracefully extended from 155 Mbit/s bidirectionally up to provide 1 Gbit/s in the downstream direction and 576 Mbit/s in the upstream direction. Subcarrier multiplexing is used to extend the bandwidth. Digital subscriber line (DSL) technology is used to provide broadband services over existing copper wires. The project is evaluating the tradeoff between use of optical fiber or copper in the access network. Life cycle cost studies compares different deployment scenarios for business and residential subscribers. Field trials are installed in Denmark, Portugal and Poland in order to evaluate the system under real life conditions.
