摘要： A procedure for creating an optical output signal (S') in which two optical signal parts (S.sub.1, S.sub.2) of different frequencies are created from an optical signal (S) of a fixed frequency (.nu..sub.0), whereby one of the optical signal parts (S.sub.1, S.sub.2) has a data signal (D) impressed and both optical signal parts (S.sub.1, S.sub.2) together form the optical output signal (S'), the optical signal (S) is fed to two branches (4, 5), two optical sideband carriers (.nu..sub.0 -f.sub.m, .nu..sub.0 +f.sub.m) are created in one of the two branches (4, 5) with regard to the optical signal (S), one sideband carrier of which is removed, the optical signal (S) in one of the two branches (4, 5) has a data signal (D) impressed and both divided optical signal parts (S1, S2) are then brought back together to form one single optical output signal (S'). In this way the effort required for creating both optical signal parts and/or the optical output signal can be reduced.

摘要： A method for monitoring a passive optical network (1), PON, having a tree-like structure with a main line (3) and at least two branches (6.1 to 6.3), comprising: transmitting a wake-up signal (10) from the main line (3) to at least two monitoring units (DPM1 to DPM3) arranged in the at least two branches (6.1 to 6.3), in each of the monitoring units (DPM1 to DPM3), detecting the wake-up signal (10) and transmitting a response signal (A, B, C) back to the main line (3), each of the monitoring units (DPM1 to DPM3) generating a pre-defined time delay (ΔtA to ΔtC) between the detection of the wake-up signal (10) and the start of the transmission of the response signal (A, B, C), and receiving the response signals (A, B, C) at the main line (3), the receiving times (R1 to R3) of the response signals (A, B, C) being different from each other, the difference between the receiving times (R1 to R3) being adjusted by the pre-defined time delays (ΔtA to ΔtC) of the monitoring units (DPM1 to DPM3).

摘要： A prior art optical transmitter for an optical communication system having a radio system connected thereto comprises a DFB laser, an optical modulator, a signal source, and an optical filter. This optical transmitter transmits light which is not modulated by an intelligence signal. It is disadvantageous in that the optical filter and the DFB laser must be matched. An embodiment of the optical transmitter according to the invention comprises a light source (1), an optical modulator (2), and a control unit (3) which controls the light source (1) and the modulator (2) in such a way that the light emerging at the output (5) of the modulator (2) is modulated with an intelligence signal.
