摘要： A broadband communication system (SYS), which is used to distribute television, radio and video signals, is additionally used for transmitting data signals from one subscriber (TN) to another subscriber (TN). The center (ZE) of the broadband communication system (SYS) has a service-on-demand server (SOD) which contains a control facility (CONTROL). The control facility (CONTROL) receives information transmitted by a subscriber (TN) via the return channel (R) to the center, performs a frequency conversion and transmits the information via the downstream channel (V) to all the subscribers (TN) of the broadband communication system (SYS). The information contains a source address, a destination address and the subscriber-specific data to be transmitted. Only subscribers (TN) whose address coincides with the destination address are able to interpret the information through a modem MODEM.

摘要： An optical fiber amplifier is proposed comprising at least one pump light source (3), at least one amplifying fiber section (10), and at least one coupler (8) which establishes a connection between the input fiber (1) of the fiber type I, the pump light source (3), the amplifying fiber section (10), and the output fiber (12) of the fiber type I. The amplifying fiber section (10) consists of a fiber type II, and the the splices (2, 11) between the fiber type I and the fiber type II are arranged relative to the amplifying fiber section (10) such that light propagated in the direction opposite to the signal direction and light propagated in the signal direction passes through means absorbent of short wavelengths before it reaches the splices.

摘要： Regenerator sections in known regenerators, which comply with CCITT-Recommendation G.958, are supervised by monitoring the transmission error probability of SDH (synchronous digital hierarchy) signals, through determination of the parity. This requires the breakdown and restoration of the SDH signal. This requires special signal processing installations, not required for regenerating transmission signals, such as multiplexer and demultiplexer, which cause considerable loss of output. The regenerator (RE) according to the invention determines the transmission error probability by comparing a known word in the head part of an STM-N signal with a reference word. The transmission error probability is derived from the result of the comparison, and transmitted to a central unit via an error line (FL). For example, to transmit the transmission error probability in an STM-N signal, the service channel of a regenerator that complies with CCITT-Recommendation G.958 may be used.
