    • Provided is a wavelength division multiplexed-passive optical network (WDM-PON) apparatus. The WDM-PON includes an optical source unit, an optical mux, and a chirped Bragg grating. The optical source unit generates an optical signal. The optical mux receives the optical signal from the optical source unit through one end of the optical mux, multiplexes the optical signal, and outputs the multiplexed optical signal. The chirped Bragg grating is connected to the other end of the optical mux. The chirped Bragg grating again reflects the optical signal having passed the optical mux to re-input a certain portion of the optical signal into the optical mux and the optical source unit. The optical mux performs a spectrum slicing on the re-inputted optical signal and operates the optical source unit using a channel wavelength of the optical mux as a main oscillation wavelength.
    • 提供了一种波分复用无源光网络(WDM-PON)装置。 WDM-PON包括光源单元,光复用器和啁啾布拉格光栅。 光源单元产生光信号。 光复用器通过光复用器的一端从光源单元接收光信号,复用光信号,并输出复用的光信号。 啁啾布拉格光栅连接到光复用器的另一端。 啁啾布拉格光栅再次反射已经通过光复用器的光信号,以将光信号的某一部分重新输入光复用器和光源单元。 光复用器对重新输入的光信号执行频谱分片,并使用光复用器的信道波长作为主振荡波长来操作光源单元。

    • Provided is a media deposit apparatus including: a deposit transfer portion providing a deposit circulation path of media deposited via a media deposit portion; a temporary transfer portion providing a temporary circulation path that contacts with the deposit circulation path to transfer the media to a temporary stack portion, and including a temporary stack gate, provided between the deposit circulation path and the temporary circulation path, to selectively convert a path of media to the temporary circulation path; and a media transfer portion providing a media transfer path that contacts with the temporary circulation path to transfer the media to a media storage portion, and including a media storage gate, provided between the temporary circulation path and the media transfer path, to selectively convert the path of media to the media transfer path. Accordingly, it is possible to simplify a media transfer structure and to enhance a media transfer efficiency.
    • 提供了一种介质沉积设备,包括:沉积物转移部分,其提供通过介质沉积部分沉积的介质的沉积物循环路径; 临时转移部分,提供临时循环路径,其与沉积物循环路径接触以将介质转移到临时堆叠部分,并且包括设置在沉积物循环路径和临时循环路径之间的临时堆叠门,以选择性地将路径 的媒体到临时流通路线; 以及介质传送部分,其提供与临时循环路径接触以将介质传送到介质存储部分的介质传送路径,并且包括设置在临时循环路径和介质传送路径之间的介质存储门,以选择性地将 媒体路径到媒体传输路径。 因此,可以简化介质传送结构并提高介质传送效率。
