    • A method and apparatus for testing an optical cable is provided. In one embodiment, the apparatus may include a receiver for receiving a received pulse train through the optical cable. The apparatus may further include a cross-correlation system in communication with the receiver. The cross-correlation system may be adapted to determine a cross-correlation of the received pulse train and matched filter to an expected pulse train. The apparatus may further include a comparator in communication with the cross-correlation system. The comparator may be adapted to compare the cross-correlation to a threshold. The apparatus may also include an output transmitter, in communication with the comparator. The output transmitter may be able to output a comparison-result output that includes the results of the comparator comparison of the cross-correlation against a threshold.
    • 提供了一种用于测试光缆的方法和装置。 在一个实施例中,该装置可以包括用于通过光缆接收接收的脉冲串的接收器。 该装置还可以包括与接收机通信的互相关系统。 互相关系统可以适于确定接收到的脉冲串和匹配滤波器与预期脉冲串的互相关。 该装置还可以包括与互相关系统通信的比较器。 比较器可以适于将互相关与阈值进行比较。 该装置还可以包括与比较器通信的输出发射器。 输出发射器可以能够输出比较结果输出,其包括互相关比较器与阈值的比较结果。
