A remote node architecture for a fiber-optic network, especially for low bit-rate data transmission, the fiber-optic network architecture comprises a central node and a plurality of remote nodes serially connected to each other or to the central node, respectively. The central node and the remote nodes are capable of communicating by means of digital optical signals created by the central node or a respective remote node, each digital optical signal comprising a data frame. The remote node comprises an optical connection network, a single transceiver device comprising an optical receiver unit and an optical transmitter unit, and an electronic controller device for controlling the transceiver device. The optical connection network defines 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.
