摘要： In an optical isolator device using a Faraday rotator for permitting a forward light beam to pass therethrough but for preventing a reverse light beam from passing therethrough, two Faraday rotators are used in a cascade-connection in order to improve the temperature characteristic of the isolation over a wide temperature range. One of two Faraday rotators is prepared to have the Faraday rotation angle of 45.degree. for a wavelength shorter than the intended wavelength .lambda..sub.0, while the other having the Faraday rotation angle of 45.degree. for a wavelength longer than .lambda..sub.0. A polarizer and an analyzer are disposed on opposite ends of one of the rotators at a rear stage and prevent the reverse light beam from passing therethrough. Another polarizer and another analyzer can further be disposed at opposite ends of the other front stage rotator so that two isolators are arranged in a cascade-connection. The rotation angular deviation of the light beam caused at the front stage rotator by the temperature variation is cancelled by the rotation angular deviation caused at the rear stage rotator by the same temperature variation.

摘要： It is the object of the invention to provide an optical signal receiving apparatus, which is used in a narrow band WDM optical transmission system, and never misguidedly receives an adjacent optical signal, when an optical signal to be received is down. An optical signal to be received is extracted from plural WDM optical signals by an optical BPF, a central wavelength of which coincides with the wavelength of the optical signal to be received, and converted into an electrical signal by the O/E converter. A tone-signal extracting circuit extracts the frequency component of the tone-signal, which is superposed on the optical signal with the wavelength equal to the central wavelength of the optical BPF. If the extracted signal level of the tone signal is lower than that of a predetermined standard voltage, a comparator supplies a reset signal to an electrical signal decision circuit. If the optical signal with a desired wavelength is down, the output level of a tone-signal extracting circuit becomes low, and the electrical signal decision circuit is reset. Then, even if the clock signal of the adjacent optical signal is extracted, the adjacent optical signals is not misguidedly discriminated and regenerated by the electrical signal decision circuit.

摘要翻译： 本发明的目的是提供一种在窄带WDM光传输系统中使用的光信号接收装置，并且当待接收的光信号下降时，不会错误地接收相邻的光信号。 通过光学BPF从多个WDM光信号中提取要接收的光信号，该光学BPF的中心波长与要接收的光信号的波长一致，并由O / E转换器转换成电信号。 音调信号提取电路提取音调信号的频率分量，该音调信号叠加在波长等于光学BPF的中心波长的光信号上。 如果提取的音调信号的信号电平低于预定标准电压的信号电平，则比较器将复位信号提供给电信号判定电路。 如果所需波长的光信号下降，则音信号提取电路的输出电平变低，电信号判定电路复位。 然后，即使提取出相邻的光信号的时钟信号，也不会由电信号判定电路误差地识别和再生相邻的光信号。
