    • PURPOSE: An add/drop multiplexer is provided to reduce occupation area of network by using a reflecting structure in which the inputted wavelength channel is reflected and output. CONSTITUTION: An optical input/output part inputs an optical signal which is inputted from outside, or outputs a transmitted optical signal to outside. A router reflects the optical signal transmitted from the optical input/output part or an optical switching part and outputs the optical signal to the optical input/output part or an optical switching part by using a first reflection mirror(511). The optical switching part reflects the optical signal transmitted from the router and transmits to the router, or performs a switching process about the dropped optical signal so that the adding process is to be achieved by using a second reflection mirror(517). Accordingly, a 2x2 optical switch structure and an arrayed wave guide grating router(AWGR) structure can be reduced in a half volume by using the first reflection mirror and second reflection mirror, respectively.
    • 目的:提供一种分插复用器,通过使用其中输入的波长信道被反射和输出的反射结构来减少网络的占用面积。 构成:光输入输出部输入从外部输入的光信号,或将发送的光信号输出到外部。 路由器反射从光输入/输出部分或光切换部分发送的光信号,并通过使用第一反射镜(511)将光信号输出到光输入/输出部分或光切换部分。 光切换部分反映从路由器发送的光信号并发送到路由器,或者执行关于丢弃的光信号的切换处理,以便通过使用第二反射镜(517)来实现加法处理。 因此,通过分别使用第一反射镜和第二反射镜,可以将1/2×2光开关结构和阵列波导光栅路由器(AWGR)结构减小到一半体积。

    • An optical fiber according to the present invention includes: a tube including an input end which is formed to extend in at least one direction and receives light, and an output end outputting the light; and a core filling the tube. The tube includes a first tension unit which is formed in the extending direction of the tube and has a resilient tension in the extending direction. According to the embodiments of the present invention, the tension unit is flexibly constricted according to the volume change of the core due to the outflow of OH groups to maintain a predetermined pressure within the tube. Accordingly, the present invention can suppress the generation of bubbles due to the OH groups by constricting the tension unit once the OH-group in the core leaves to the outside over time to push and remove the space of the left OH groups.
    • 根据本发明的光纤包括:管,其包括形成为沿至少一个方向延伸并接收光的输入端和输出光的输出端; 和填充管的核心。 该管包括沿着管的延伸方向形成并在延伸方向上具有弹性张力的第一张力单元。 根据本发明的实施例,张力单元由于OH基团的流出而根据芯的体积变化而灵活地收缩,以保持管内的预定压力。 因此,本发明通过一旦OH核心离开外界时,通过收缩张力单位来抑制OH基产生气泡,从而推动和去除左OH基团的空间。
