  • Patent number: 9008506
    Abstract: A fiber network events measurement apparatus has a laser module alternately generating a pulse signal detecting beam and an FMCW detecting beam. The beams are sent to the fiber network route through a directional coupler. A photo detector receives feedback energy of the beams transmitting in the fiber network route and converts the feedback energy into electronic signals. A mixer uses a frequency difference calculation to obtain a comparison result according to an original and a reflected FMCW signal. The electronic signal is converted into a digital signal by an A/D converter. A signal control unit then obtains a compound trace result including information of characteristic trace and event positions. The compound trace result shows a fiber characteristic trace and event position trace for measuring the fiber network routes.

  • Patent number: 8837937
    Abstract: A detecting device that detects insertion loss of fiber route and return loss of individual events in an optical fiber network based on signals from dual paths to obtain various kinds of reference information of the optical fiber network. When the first path is selected, a detection signal produced using frequency modulated continuous wave (FMCW) technique is output to the optical fiber network. A return signal of the detection signal is used to analyze the position and return loss of various events in the optical fiber network. When the second path is selected, a common detection light is output to the optical fiber network. Based on the return signal of the common detection light, the insertion loss and total return loss of the entire network are obtained.

  • Patent number: 7180933
    Abstract: A squelch circuit for operating at high speed and at high frequencies includes a squelch input unit, a low swing pre-amplifier and a sampling and decision circuit. The squelch input unit pre-processes the positive and negative signals of an input signal to generate four pre-processed signals that are paired and sent to the low swing pre-amplifier. The outputs of the low-swing pre-amplifier are then over-sampled by the sampling and decision circuit. Multi-phase clocks are used to control the over-sampling in the sampling and decision circuit. A logic circuit then determines if the state of the input signal based on multiple samples.
