    摘要: An add-drop optical spectrum-division multiplexer for dropping a drop multiplex from an incoming multiplex signal and for adding an add multiplex into an outgoing multiplex signal. The multiplexer includes a demultiplexing device for separating a number of optical carriers from the incoming multiplex signal and for selecting drop carriers which constitute the drop multiplex as well as through carriers which are to be output as the outgoing multiplex signal. The multiplexer further includes an apparatus for selecting a certain number of add carriers from the total number of carriers of the add multiplex, and a coupling device and wavelength converter for allocating fixed wavelengths to the signals which modulate the through carriers and the add carriers.

    摘要: An optical connection system for connecting customer premises networks to a switching center of a telecommunication network providing interactive and non-interactive services includes a switching center comprising central office termination equipments, a connection network, a control unit, an optical distribution network and customer premises networks. Non-interactive services are connected to the control central office termination equipment so that non-interactive service signals are sent to all customer premises networks on standby at the control central office termination equipment wavelength. These customer premises networks can therefore use these services without having to set up a call individually and so without having to busy a central office termination equipment for each customer premises network. Each customer premises network which requests a non-interactive service during an interactive call retains the same wavelength and the same central office termination equipment assigned to it for the interactive call. The system finds an application in broadband telecommunication networks.
