Patent number: 9008506Abstract: 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.Type: GrantFiled: February 6, 2013Date of Patent: April 14, 2015Assignee: Polarlink Technologies, Ltd.Inventors: Ching-Wen Hsiao, Hsuan-Hung Wu, Shih-Tien Lin, Fu-Chun Hung, Yu-Shu Chen, Ching-Lin Wu, Chun-Hung Su
