20090074366 | Optical fiber line arranging guide groove capable of sensing optical signals - An optical fiber line arranging guide groove capable of sensing optical signals is provided, which is used for solving a problem that optical fiber lines are disordered and hard to be arranged due to an excessive large number of optical fiber lines existed, and further used for detecting the status of optical signals in the optical fiber line. Through an optical detection circuit and a display element, the connection status of optical signals for the optical fiber line in the optical fiber line arranging guide groove is determined. | 03-19-2009 |
20090073546 | Optical path switching device - An optical path switching device is provided. The optical path switching device utilizes the electro-optic effect to apply an electric field on different reflective elements without moving an input/output end of optical signal or reflective elements. Thus, the reflective elements reflect optical beams to control travel paths of the optical beams, so as to switch the optical paths in the absence of mechanical motion. | 03-19-2009 |
20090022493 | PON equipment capablel of displaying connection state and logical link identifier - A passive optical network (PON) equipment capable of displaying a connection state and a logical link identifier (LLID) is provided, which aims at solving a problem that equipments in the conventional PON system cannot display connection state and LLID. The PON equipment displays the connection state and the LLID through a programmable logic element and a display unit by utilizing characteristics of multi-point control protocol (MPCP) and LLID, so as to achieve the efficacy of displaying the connection state and the LLID. | 01-22-2009 |
20090021915 | Multi-layer heat-dissipating device - A multi-layer heat-dissipating device is provided. The multi-layer heat-dissipating device does not use fans, absorbs heat energy sequentially with heat-conducting elements and a heat-dissipating metal sheet, and effectively blocks heat radiation of a heat-generating element, so as to achieve the effects of power saving, no noise, and less occupied space. | 01-22-2009 |
20090020660 | Adjustable stand for electronic devices - An adjustable stand for electronic devices mainly adapted to eliminate limitation on viewing angle adjustment of conventional adjustable stands is provided. The adjustable stand includes a main body, a first support frame, a second support frame, a pivot, and a sleeve. The pivot passes through and positions each of the components. A pressing portion on the pivot is used to operate the pivot and controls the movement of the pivot. Thus, a supporting angle of the first support frame and the second frame can be adjusted freely to create various viewing angles, such that the viewing angle adjustment can be adapted for different conditions and requirements diversely. | 01-22-2009 |
20090016720 | Problem detection device at ONU end in PON system and method thereof - A problem detection device at an optical network unit (ONU) end in a passive optical network (PON) system and a method thereof are provided, which aim at solving the problem that the user cannot check out photo-physical data on the physical architecture, logical signal information on the logical architecture, and parameter information on the network communication protocol of the PON system economically, quickly, and accurately, once a connection error occurs at the ONU end. The technical lies in using an optical network signal to pass through the integrated optical path analysis module, the ONU module, and the network communication protocol message analysis module included in the problem detection device to achieve the detection and analysis of the problem of the ONU connection error at one time once the problem detection device is connected to the PON system. | 01-15-2009 |
