Mumakore achangopfuura, nerutsigiro rwemitemo yenyika yeindasitiri yebroadband, iyo ADSS fiber optic cable indasitiri yakagadzira nekukurumidza, iyo yakaperekedzwa nematambudziko mazhinji.
Aya anotevera ndiwo anotsanangura muchidimbu nzira shanu dzekuyedza zvichienderana nekupokana kwenzvimbo yekukanganisa:
1. Kana kushorwa kwenzvimbo yekukanganisa kwakaenzana nekusingaperi, zviri nyore kuwana kushayikwa kwedunhu rakavhurika ne-low-voltage pulse method.Kazhinji kutaura, zvikanganiso zvakavhurika zvedunhu hazvina kujairika.Kazhinji zvikanganiso zvakavhurika zvedunhu zvine zvishoma pasi kana chikamu-ku-chikamu chepamusoro-impedance zvikanganiso, uye zvishoma pasi kana chikamu-kusvika-chikamu chakaderera Kugarisana kwekupokana kwekupokana.
2. Kana kushorwa kwechikanganiso chakaenzana ne zero, zviri nyore kuwana kukanganisa kwekanguva-pfupi nekuyera kukanganisa kwekanguva-pfupi ne-low-voltage pulse method, asi hazviwanzoitiki mubasa chairo.
3. Kana kushorwa kwechikanganiso chakakura kudarika zero uye pasi pe100 kilohms, zviri nyore kuwana zvikanganiso zvakaderera nekuyera ne-low-voltage pulse method.
4. Kukanganisa kweFlashover kunogona kuyerwa nenzira yakananga flash.Kukanganisa kwakadaro kunowanzo kuve mukati mekonikisheni.Kupokana kwenzvimbo yekukanganisa kwakakura kupfuura 100 kilohms, asi kukosha kunoshanduka zvakanyanya, uye kuyerwa kwega kwega hakuna chokwadi.
5. Kukanganisa kwepamusoro-soro kunogona kuyerwa ne-flash-flash nzira, uye kukanganisa kunopikisa kwakakura kudarika 100 kilohms uye kukosha kunotarirwa.Kazhinji, kana bvunzo iripo yakakura kupfuura 15 mA, mafungu ebvunzo anodzokororwa uye anogona kupindirana, uye waveform ine imwe chete inobuda, matatu maratidziro uye pulse amplitude inodzikira zvishoma nezvishoma, chinhambwe chakayerwa chinhambwe kubva pakakanganisika kuenda kutambo. test end;kana zvisina kudaro Edza chinhambwe kubva pane chikanganiso kusvika kune yakatarisana netambo yetambo.
