Abstract: A broadband integrated subscriber loop system is provided in accordance with the teachings of the present invention. A system is provided in which the subscribers are combined in groups (T1n1-T1n10) each of which is supplied via a single optical communication link. Over the optical waveguide (LWL) of this optical communication link, signals of the channels assigned to subscribers for various telecommunication services are transmitted on a multiplexed basis from the switching unit to an interface unit closely located to the subscribers of the group. In the interface unit the channels are separated and subscriber-assigned multiplexers (Mux 5) combine the channels assigned to a subscriber in accordance with the transmission capacity required into a subscriber time-division-multiplex signal. This signal is transmitted over a subscriber line in the form of a coaxial electric line (KL 1) to subscriber's taps, where the signals for terminals located at the top are separated via demultiplexers (Demux 3, Demux 4, Demux 5, Demux 6). Signals to be transmitted from a subscriber's terminals to the switching unit are combined in digital form (Mux 2, Mux 3, Mux 4), and a multiplexer (Mux 1) in the interface unit combines signals from all subscribers of the group into a back-channel multiplex signal which is transmitted to the switching unit over an optical communication link using the same or a second optical waveguide. In the switching unit, a demultiplexer (Demux 1) separates the received signals into the signals from the individual subscribers, and the signals of each subscriber are split up according to the subscriber's various telecommunications services. The system, including the terminals, is fully digital.

Abstract: Optical communications system for the subscriber area with optical amplifiers.The system according to the invention is used to distribute information signals, particularly telephone signals, from a center to a plurality of subscribers and to make possible a bidirectional transmission of telephone and data signals between the center and the subscribers. According to the invention, the network used for this purpose is a multistar fiber-optic network in which fiber-optic amplifiers (10, 11) are present between successive branch points. The information signals to be distributed are transmitted via the fiber-optic network with a first wavelength (.lambda..sub.1) to the subscribers, and the subscriber-specific information signals to be transmitted from the center (1) to the subscribers (T.sub.i) are converted by frequency modulation to a different frequency band (FB.sub.2) than the distribution signals (by frequency modulation) and transmitted to the subscribers at the same wavelength as the distribution signals, and the subscriber-specific signals to be transmitted from the subscribers (T.sub.i) to the center (1) are converted by frequency modulation to another frequency band (FB.sub.3) and are transmitted optically to the center with a second wavelength (.lambda..sub.2). This optical signal is amplified at suitable points (A) and several alternative embodiments for this amplification are indicated.

Abstract: The invention relates to an optical communication system for transmitting subscriber-assigned information in both directions between a center (1) and a plurality of subscribers (3ato 3n), particularly to the subscriber loop of a broadband communication system. In a remote distribution facility which is of either distributed (FIG. 1) or lumped (FIG. 2) design, the optical waveguides (5ato 5n) of a group of subscribers living or working near each other are coupled to a common optical waveguide (4) (or to two common optical waveguides) connected to the center (1). Subscriber-assigned signals to be transmitted from the center to the subscribers are combined into an electric time-division-multiplex signal which is transmitted as an optical signal with a single wavelength (.lambda..sub.o) to the vicinity of the subscribers and distributed to the latter. From the electric time-division-multiplex signal, each of the subscribers takes only the signal intended for him. The signals to be transmitted from the subscribers to the center are transmitted as optical signals with subscriber-assigned wavelengths (.lambda..sub.l to .lambda..sub.n ) through subscriber-as-signed optical waveguides to the common optical waveguide (4), are coupled into the latter, and are transmitted as a wavelength-division-multiplex signal to the center.

Abstract: For short-distance communication systems, particularly for optical-waveguide links in the subscriber area, it is proposed to operate the standard single-mode optical waveguide for long-distance applications, which is optimized for the wavelength range from 1300 nm to 1600 nm, with optical transmitters and optical receivers whose operating wavelengths lie clearly below the cutoff wavelength of the optical waveguide. By means of a suitable stable laser-waveguide coupling, it is ensured that single-mode operation is achieved, which is necessary to transmit digital signals at high bit rates. The increased loss of the optical waveguide at 800 nm can be accepted because of the relatively short length of subscriber lines. Both unidirectional and bidirectional transmission over a single optical waveguide using wavelength-division or modal multiplexing is possible.

Abstract translation: 对于短距离通信系统，特别是对于用户区域中的光波导链路，建议对长距离应用的标准单模光波导进行操作，其针对1300nm至1600nm的波长范围进行优化， 其光发射机和光接收机的工作波长明显低于光波导的截止波长。 通过合适的稳定的激光波导耦合，确保实现单模操作，这是以高比特率传输数字信号所必需的。 由于用户线路的长度相对较短，可以接受800nm处的光波导的增加的损耗。 使用波分复用或模式复用的单个光波导上的单向和双向传输都是可能的。
