Filed: 2020-02-19
Abstract: To provide an optical network monitoring device that can quickly estimate an anomalous transponder at low cost.SOLUTION: When a network monitoring device detects a failure occurrence channel, the network monitoring device acquires route information of a faulty channel. Then, an adjacent channel table is created by extracting an adjacent channel whose wavelength is close to that of the failure occurrence channel. Next, an interference channel table is created by extracting an interference channel having the same route as the failure occurrence channel from among the adjacent channels. Next, the interference channel is weighted on the basis of the proximity of the wavelength to the failure occurrence channel, and an influence channel table in which the interference channel is weighted is generated. Then, on the basis of an influence channel table, it is estimated that the channel with a large weight is a channel that may adversely affect the failure occurrence channel.SELECTED DRAWING: Figure 1

Abstract: To solve the problem that corrosion or shorting may occur to the electrode terminal formed on the substrate of a display device, and the technique of applying a coating of moisture-proof insulating material so as to cover the electrode terminal used to prevent this problem has a drawback in that most of the moisture-proof insulating material come in liquid form and precise control of the coated area is generally difficult, but since coating is applied in the final step, specifically no problems are encountered, except that a recent increase in the practice of superimposing a touch panel or a protective board on the visible side for the heightened value-addedness of display devices has brought about cases where superimpositioning results in misalignment if, for example, an alignment mark for positioning is covered with the moisture-proof insulating material.SOLUTION: By forming a contact hole in the periphery of an area where coating with a moisture-proof insulating material is prohibited, it is possible to suppress an ingress into the coating prohibited area, as the moisture-proof insulating material is rounded at an opening edge of the contact hole due to surface tension.SELECTED DRAWING: Figure 2
