| Popis: | Describes a subscriber station capable of receiving several TV channels, including a high-definition channel, over monomode optical 1.12 GHz lines. The station was designed for the integrated wideband network planned by the West German Post Office for the nineties. The narrow PCM-30 band and the 280 Mbit/s reverse direction are separated by optical wavelength multiplexing. The services are provided in a time multiplex frame of 16 channels of 70 Mbit/s each. The block diagram of the station, channel selection by sampling and by series-parallel conversion are explained. The audio part and the narrowband access for the services already in use are described. |
