The paper reports a system concept for up to 10000 subscribers which is characterized by the employment of single-mode fibers and of Gbit/s bit rates on the subscriber lines. By this, the possibility arises to offer a very flexible supply with broadband services up to several High Definition Television programs to the subscriber. Presently, an experimental system following this concept is under development in order to get experiences on the design of appropriate high speed system components. First results of the development of a Gbit/s-multiplexer, of broadband channel selector modules and of broadband switching networks are given.enbroadband networksISDNbroadband networkHDTVoptical transmissionhigh definition televisionchannel selector modulesbroadband switching networks621conference paper
