Patent number: 9797806Abstract: The dual-purpose adapter for inspecting circular (plug-type or receptacle-type) ruggedized fiber optic connector has a guide and a fitting tip. The guide is formed by fastening a template inserter to a frame in two alternative opposite directions. The template inserter has light channels corresponding in relative positions to the endfaces in the ruggedized connector, and two locating holes for coupling and aligning with the ruggedized connector through two guide pins. Depending upon the direction in which the template inserter is fastened to the frame, the fitting tip may be inserted into a respective end of the light channels to allow the optical axis of an inspector probe connected to it to intersect at right angle with PC or APC endfaces for inspection by the inspector probe. For receptacle-type connectors, the guide further includes the two guide pins which can be locked from axial movement at two positions.Type: GrantFiled: March 2, 2017Date of Patent: October 24, 2017Assignee: LIGHTEL TECHNOLOGIES, INC.Inventors: Ge Zhou, Theodore E.

Patent number: 9417444Abstract: 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.Type: GrantFiled: May 1, 2013Date of Patent: August 16, 2016Assignee: LIGHTEL TECHNOLOGIES, INC.Inventors: Shangyuan Huang, Hsuan Chieh Chang, Ge Zhou, Pai-Sheng Shen
