摘要	A light-receiving module includes: a pigtail optical fiber including a core portion for transmitting an optical signal and a cladding portion covering a side face of the core portion; an optical connector provided at a first end of the pigtail optical fiber for optically connecting a transmitting optical fiber with the end of the pigtail optical fiber; a light-receiving device having a light-receiving face for receiving the optical signal propagating through the core portion and for converting the optical signal into an electric signal; an optical coupling system for converging the optical signal emitted from a second end of the pigtail optical fiber onto the light-receiving face of the light-receiving device; and means for preventing light propagating through the cladding portion from reaching the light-receiving face of the light-receiving device so that the optical signal propagating through the core portion does not interfere with the light propagating through the cladding portion on the light-receiving face of the light-receiving device.
其他摘要	一种光接收模块，包括：尾纤光纤，包括用于传输光信号的芯部分和覆盖芯部分的侧面的包层部分;光纤连接器，设置在尾纤光纤的第一端，用于光学连接传输光纤和尾纤光纤的端部;一种光接收装置，具有光接收面，用于接收通过芯部传播的光信号并将光信号转换成电信号;光学耦合系统，用于将从尾纤光纤的第二端发射的光信号会聚到光接收装置的光接收面上;用于防止光通过包层部分传播到达光接收装置的光接收面的装置，使得通过芯部传播的光信号不会干扰在光接收面上传播通过包层部分的光光接收装置。
