Abstract:
1. A remote node architecture for a fiber-optic network, especially for low bit-rate data transmission, the fiber-optic network comprising a central node and a plurality of remote nodes serially connected to each other and to the central node, respectively, the central node and the plurality of remote nodes being capable of communicating by means of digital optical signals created by the central node or one of the plurality of remote nodes, each digital optical signal comprising a data frame, (a) a first remote node of the plurality of remote nodes comprising an optical connection network, a single transceiver device comprising an optical receiver unit and an optical transmitter unit, and a controller device for controlling the transceiver device, (b) the optical connection network defining a western optical connection port, an eastern optical connection port, an internal optical receiving port being connected to the optical receiver unit and an internal optical transmitting port being connected to the optical transmitter unit, the western and eastern optical connection ports being connected via an optical pass-through path for passing through a digital optical signal received at the western or eastern optical connection port as digital optical pass-through signal to the respective other optical connection port with at least a portion of an optical power of the received digital optical signal, and (c) the controller device, the transceiver device and the optical connection network being configured such that
