摘要	Optical stabilisation system having a signal source (1) connected to a transmission line (2) and a noise source (3). The signal source (1) comprises a laser having a number of laser modes within a first wavelength band for generating an optical transmission signal (S). The noise source generates a narrow-band noise signal which is inserted into the transmission line via coupling means (5) and is injected into the laser of the signal source (1). The noise signal forces the laser to operate in a laser mode within the noise band. Via a power distributor (11), a portion of the noise signal can also be injected into a laser of a further signal source (9) for stabilisation in a laser mode within the same noise band. Any signals outside the noise band are removed from the transmission signal by a narrow-band filter (8). The stabilisation system is applied in passive optical networks for groupwise wavelength assignment to network terminals.
其他摘要	光学稳定系统具有连接到传输线（2）和噪声源（3）的信号源（1）。信号源（1）包括在第一波长带内具有多个激光模式的激光器，用于产生光传输信号（S）。噪声源产生窄带噪声信号，该信号通过耦合装置（5）插入传输线，并注入信号源（1）的激光器中。噪声信号迫使激光器在噪声频带内以激光模式工作。通过功率分配器（11），还可以将一部分噪声信号注入另一信号源（9）的激光器中，以在相同的噪声频带内以激光模式稳定。通过窄带滤波器（8）从传输信号中除去噪声频带之外的任何信号。稳定系统应用于无源光网络，用于向网络终端分组波长分配。
