Izixwayiso

Izinyathelo Zokuphatha: Le divayisi isengozini yokulimala ngenxa ye-electrostatic discharge (ESD).

Indawo ekhululekile enganyakazi inconywa kakhulu. Landela imihlahlandlela ngokwezinqubo ezifanele ze-ESD.

Ukuphepha Kwe-Laser: Imisebe ekhishwa yimishini ye-laser ingaba yingozi emehlweni abantu. Gwema ukuchayeka kweso emisebeni eqondile noma engaqondile.

Izithombe zemininingwane yomkhiqizo:

Umhlahlandlela Womkhiqizo Ohlobene:

Ngokuvamile sikunikeza ngokuqhubekayo amasevisi abathengi abaqotho, kanye nezinhlobonhlobo ezibanzi kakhulu zemiklamo nezitayela ezinekhwalithi ephezulu. Lezi zinhlelo zifaka phakathi ukutholakala kwemiklamo eyenziwe ngokwezifiso enesivinini kanye nokuthunyelwa kwe-Good Quality Aoc/Dac Cable - 25G SFP28 Active optical cable JHA-SFP28-25G-AOC – JHA , Umkhiqizo uzohlinzeka emhlabeni wonke, njengale: Las Vegas , Lisbon, Danish, Umnyango wethu we-R&D uhlale uklama ngemibono emisha yemfashini ukuze sethule izitayela zemfashini zamuva nje nyanga zonke. Izinhlelo zethu eziqinile zokuphatha ukukhiqiza zihlala ziqinisekisa imikhiqizo ezinzile nesezingeni eliphezulu. Ithimba lethu lezohwebo lihlinzeka ngezinsizakalo ezifika ngesikhathi nangempumelelo. Uma kukhona intshisekelo kanye nemibuzo mayelana nemikhiqizo yethu, sicela usithinte ngesikhathi. Sithanda ukusungula ubudlelwano bebhizinisi nenkampani yakho ehlonishwayo.

Umuntu othengisayo unomsebenzi futhi unomthwalo wemfanelo, unemfudumalo futhi unesizotha, saba nengxoxo emnandi futhi ayikho imigoqo yolimi ekukhulumisaneni.
