    • A fault searching system for an optical line searches a fault in an optical line connected with an optical fiber carrying out data transmission between from a transmission apparatus at a center station side via an optical divider (PON) up to a user optical terminal. An OTDR carries out a test for the optical fiber based on backward scattering light or return light from the optical fiber by making test light be incident into the optical fiber. A connecting unit detaches a terminal portion of the optical line at an inside of the user optical terminal from the inside of the user optical terminal, and connects the OTDR to the terminal portion of the optical line. An incident unit makes at least one of test light with a wavelength different from a wavelength of light used for data transmission in the optical line, and test light whose peak level is less than or equal to a predetermined level be incident upon the terminal portion of the optical line from the OTDR. A searching unit searches for a fault in the optical line from the user optical terminal side by detecting backward scattering light or return light from the optical line which is obtained based on the incidence of the test light by the OTDR.
    • 光线路故障检索系统通过光分路器(PON)到用户光学终端,在与中心站侧的发送装置进行数据传输的光纤线路连接的光线路中检测故障。 OTDR通过使测试光入射到光纤中,基于反向散射光或来自光纤的返回光进行光纤的测试。 连接单元将用户光学终端内部的光线路的终端部分从用户光学终端的内部分离,并将OTDR连接到光学线路的终端部分。 入射单元产生波长不同于光线中用于数据传输的光的波长的测试光中的至少一个,并且峰值电平小于或等于预定水平的测试光入射到 来自OTDR的光线路。 搜索单元通过检测来自基于通过OTDR的测试光的入射所获得的光线路的反向散射光或返回光来从用户光学终端侧搜索光线路中的故障。
