Ne. Andersen et al., BROADBANDLOOP - A FULL-SERVICE ACCESS NETWORK FOR RESIDENTIAL AND SMALL BUSINESS USERS, IEEE communications magazine, 35(12), 1997, pp. 88-93
There is a worldwide effort to define a full-service access network. T
he Broadbandloop project was formed by a European consortium funded by
the European Union with the objective of defining a strategy for evol
ution from a narrowband voice and data network to a broadband network.
The project is defining a system concept based on new innovative PON
technology, which enables fiber to cost effectively penetrate close to
the customer, and VDSL technology for transmission over twisted coppe
r pairs. The system concept is validated in field trials in Denmark, P
ortugal, and Poland. The article describes the different requirements
for a full-service access network, the system concept, and technologie
s developed. Results from modeling of broadband traffic and the corres
ponding bandwidth are given. The cost effectiveness of using new optic
al fiber vs. reusing existing telephone copper plant has been evaluate
d, and results from these studies are presented.
