  • Patent number: 10353149
    Abstract: An optical fiber coating stripper includes a pair of electrodes, each of which having a discharge head portion and an electrode portion, and a gliding plasma (GP) head housing the electrodes therein. The GP head includes internal airflow channels. The pair of electrodes are disposed at a front end of the GP head and form an air gap therebetween. Each of the discharge head portion includes a curved portion with a rib-shaped protrusion extending in a longitudinal direction of the discharge head portion. In operation, the electrodes are connected to non-alternating electrically positive and negative polarities. When a gas flows through the internal airflow channels in a direction a back end of the GP head toward the front end, a tongue-shaped GP flow is formed in the air gap between the rib-shaped protrusions of the discharge head portions.

  • Patent number: 9417444
    Abstract: A wireless fiber optic endface inspector includes a video microscope capable of wirelessly transmitting video streaming signal of endface image in real-time to a display device. The video microscope includes a microscope optical system, an adapting tip for interfacing an endface, an LED light source, a camera module for receiving and converting the endface image into video streaming signal, a Wi-Fi AP board, and a battery for supplying power. The video microscope may be constructed by adding a Wi-Fi AP board and a battery to a conventional inspector microscope. The display device has software for detecting when the endface is focused. Once the endface is focused, the display device emits an audio signal to alert the operator, who may then trigger the display device to analyze the endface image using an endface analysis software or save it to a folder, or transmit the image to a remote server.
