    • The object of the present invention is to provide an optical module for the WDM communication system, in which the oscillation wavelength is on the grid of the WDM regulation, moreover the optical output power and the oscillation wavelength can be controlled independently. The present module comprises a semiconductor light-emitting device, a wedge shaped etalon device and two light-receiving devices. The etalon device contains a first portion, on which the anti-reflection films are coated, and a second portion. One of the receiving devices detects light transmitted through the first portion of the etalon device, while the other device detects light through the second portion. Signal from the former device controls the output power of the light-emitting device, while the signal from the latter receiving device controls the oscillation wavelength of the laser.
    • 本发明的目的是提供一种用于WDM通信系统的光模块,其中振荡波长在WDM调节电网上,而且可以独立地控制光输出功率和振荡波长。 本模块包括半导体发光器件,楔形标准器器件和两个光接收器件。 标准具装置包括第一部分,其上涂覆有防反射膜,第二部分。 接收装置中的一个检测通过标准具装置的第一部分透射的光,而另一个装置通过第二部分检测光。 来自前一个装置的信号控制发光装置的输出功率,而来自后一个接收装置的信号控制激光器的振荡波长。

    • A read-out signal generator supplies read-out signals through a read-out bus bar to sources of first data signals and buffer memories storing second data signals produced by accompanying central processing units (CPU's) to make the read-out bus bar transmit also the first and second data signals in timed relation to the read-out signals. A coupling device supplies read-in signals with reference to the read-out signals and transfers the first and second data signals from the read-out bus bar to a read-in bus bar, which supplies the transferred data signals to the CPU's in predetermined time relation to the read-in signals. The coupling device may either be a mere connection (in which case the read-out signals serve as the read-in signals) or a data bank.
    • 读出信号发生器通过读出母线将读出的信号提供给第一数据信号源和存储由伴随的中央处理单元(CPU)产生的第二数据信号的缓冲存储器,以使读出的母线也发送 与读出信号定时关系的第一和第二数据信号。 耦合装置参考读出的信号提供读入信号,并将第一和第二数据信号从读出母线传送到读入母线,该母线将传送的数据信号提供给CPU的预定 与读入信号的时间关系。 耦合器件可以是单纯的连接(在这种情况下,读出的信号用作读入信号)或数据库。
