    • An optical transceiver module can reduce the number of mounting steps by automatically arranging a plurality of filters with the alignment of the glass substrates. The optical transmission module comprises the optical element mounting substrate(1) and optical multiplexing/demultiplexing device(2). At least the first and the second emitting device are mounted in the optical device loading substrate. The optical multiplexer/demultiplexing device comprises the first wave length selection filter(6) and mirror(8). The mirror is parallelly installed with the first wave length selection filter. The optical multiplexer/demultiplexing device is fixed within the package(3). The first and second light-emitting devices project first and second emission lights to the optical multiplexer/demultiplexer. And then, in the second emission light is multiplexed with the first emission light in the first wave length selection filter.
    • 光收发器模块可通过玻璃基板的对准自动布置多个滤光片来减少安装步骤的数量。 光传输模块包括光学元件安装基板(1)和光复用/解复用装置(2)。 至少第一和第二发光器件安装在光学器件加载衬底中。 光复用器/解复用装置包括第一波长选择滤波器(6)和反射镜(8)。 镜子与第一波长选择滤光片并联安装。 光复用器/解复用装置固定在封装(3)内。 第一和第二发光装置将第一和第二发射光投射到光复用器/解复用器。 然后,第二发光与第一波长选择滤波器中的第一发射光多路复用。
