20150038063 | PORTABLE OPTICAL FIBER END FACE POLISHER - The present invention provides a portable optical fiber end face polisher that has a probe, a shuttle, a cover and a resilient actuator. The probe has a driving shaft holding a pin having two through holes. The shuttle holds the driving shaft, a supplying reel and a spooling reel. The cover guides the driving shaft to rotate axially and draws a cleaning medium from the supplying reel to pass through the through holes across a probing face of the pin to the spooling reel. The resilient actuator is mounted between a stopping base of the cover and the shuttle to recover the relative positions of the shuttle and the cover. | 02-05-2015 |
20140161444 | Remotely Controlled Fiber Testing Method - A remotely controlled fiber testing method has the steps of: building a fiber network system including a local fiber station and a remote fiber station; sending a modulated signal to the remote fiber station by the local fiber station; demodulating the modulated signal to obtain a control command by the remote fiber station; executing the control command to obtain a testing result by the remote fiber station; modulating the testing result and sending the testing result back to the local fiber station; and demodulating the testing result by the local fiber station. Only one technician appointed to the local fiber station is sufficient to do the testing action. Therefore, the personnel cost is effectively reduced. | 06-12-2014 |
20130322874 | Detecting Device for Detecting Insertion Loss and Return Loss of Individual Events in an Optical Fiber Network - 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. | 12-05-2013 |
20130322871 | FIBER NETWORK EVENTS MEASUREMENT APPARATUS - 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. | 12-05-2013 |
