Njengoba ubuchwepheshe buhlanganiswa kakhulu ezimpilweni zethu zansuku zonke, ukukhathazeka ngemisebe ye-electromagnetic (EMR) evela kumishini kagesi kuyakhula. Ukushintsha kwenethiwekhi kuyisici esibalulekile kumanethiwekhi esimanje futhi anjalo. Lesi sihloko sidingida ukuthi amaswishi enethiwekhi ayayikhipha yini imisebe, amaleveli emisebe enjalo, kanye nomthelela kubasebenzisi.
Iyini imisebe ye-electromagnetic?
Imisebe ye-electromagnetic (EMR) ibhekisela emandleni ahamba emkhathini ngendlela yamagagasi kagesi. Lawa maza ayahluka ngobuningi futhi ahlanganisa amaza omsakazo, ama-microwave, infrared, ukukhanya okubonakalayo, i-ultraviolet, i-X-ray, nemisebe ye-gamma. I-EMR ngokuvamile ihlukaniswa ibe imisebe ye-ionizing (imisebe enamandla amakhulu engabangela umonakalo ezicutshini zebhayoloji, njengama-X-ray) kanye nemisebe engeyona i-ionizing (amandla aphansi angenawo amandla anele oku-ionize ama-athomu noma ama-molecule, njengamaza omsakazo. kanye nama-oven microwave).
Ingabe amaswishi enethiwekhi akhipha imisebe ye-electromagnetic?
I-network switch iyisisetshenziswa sikagesi esisetshenziselwa ukuxhuma amadivaysi ahlukahlukene ngaphakathi kwenethiwekhi yendawo (LAN). Njengamadivaysi amaningi kagesi, amaswishi enethiwekhi akhipha izinga elithile lemisebe kagesi. Nokho, kubalulekile ukuhlukanisa phakathi kohlobo lwemisebe ekhishwayo kanye nemiphumela yayo engaba khona empilweni.
1. Uhlobo lwe-radiation switch yenethiwekhi
Imisebe yezinga eliphansi engeyona i-ionizing: Amaswishi enethiwekhi ikakhulukazi akhipha imisebe yezinga eliphansi engeyona i-ionizing, okuhlanganisa imisebe yefrikhwensi yomsakazo (RF) kanye nemisebe yefrikhwensi ephansi kakhulu (ELF). Lolu hlobo lwemisebe lufana nalolo olukhishwa ama-electronics amaningi asendlini futhi alunamandla ngokwanele okwenza ama-athomu e-ionize noma abangele ukulimala okuqondile kwezicubu zezinto eziphilayo.
I-Electromagnetic Interference (EMI): Amaswishi enethiwekhi angaphinda akhiqize ukuphazamiseka kwe-electromagnetic (EMI) ngenxa yamasiginali kagesi abawaphethe. Kodwa-ke, amaswishi enethiwekhi yesimanje aklanyelwe ukunciphisa i-EMI futhi athobelane nezindinganiso zomkhakha ukuze kuqinisekiswe ukuthi awabangeli ukuphazamiseka okukhulu kwamanye amadivayisi.
2. Amazinga nezindinganiso zokukhishwa kwemisebe
Ukuthobelana nezindinganiso zokuphepha: Amaswishi enethiwekhi angaphansi kwamazinga okulawula abekwe izinhlangano ezifana ne-Federal Communications Commission (FCC) kanye ne-International Electrotechnical Commission (IEC). Lawa mazinga aqinisekisa ukuthi okokusebenza kwe-elekthronikhi, okuhlanganisa nokushintsha kwenethiwekhi, kusebenza ngaphakathi kwemikhawulo ephephile yemisebe kazibuthe kagesi futhi azizibeki izingozi zempilo.
Ukuchayeka Kwemisebe Ephansi: Amaswishi enethiwekhi ngokuvamile akhipha amazinga aphansi kakhulu emisebe uma kuqhathaniswa neminye imithombo yemisebe kagesi, njengamaselula namarutha e-Wi-Fi. Imisebe yayingaphakathi kwemingcele ephephile ebekwe yiziqondiso zamazwe ngamazwe.
imiphumela yezempilo nokuphepha
1. Ucwaningo kanye Nokutholwa
I-Non-ionizing Radiation: Uhlobo lwemisebe ekhishwa amaswishi enethiwekhi luwela ngaphansi kwesigaba semisebe engeyona i-ionizing futhi ayizange ixhunywe nemiphumela emibi yezempilo ocwaningweni lwesayensi. Ucwaningo olubanzi nokubuyekezwa kwezinhlangano ezifana ne-World Health Organization (WHO) kanye ne-International Agency for Research on Cancer (IARC) akutholanga ubufakazi obuqand' ikhanda bokuthi amazinga aphansi emisebe engeyona i-ionizing evela kumishini efana nokushintshwa kwenethiwekhi adala izingozi ezinkulu zezempilo.
Izexwayiso: Nakuba ukuvumelana kwamanje kungukuthi imisebe enga-ionizing evela ekushintsheni kwenethiwekhi ayiyingozi, kuhlale kuwubuhlakani ukulandela izinqubo zokuphepha eziyisisekelo. Ukuqinisekisa ukungena komoya ngendlela efanele kwempahla kagesi, ukugcina ibanga elifanelekile ukusuka kumpahla kagesi eminyanisa kakhulu, kanye nokulandela imihlahlandlela yomkhiqizi kungasiza ukunciphisa noma yikuphi ukuchayeka okungaba khona.
2. Ukuqondisa ngokomthetho
Ama-ejensi alawulayo: Ama-ejensi afana ne-FCC ne-IEC alawula futhi aqaphe izinto zikagesi ukuze ziqinisekise ukuthi zihlangabezana namazinga okuphepha. Amaswishi enethiwekhi ayahlolwa futhi agunyazwe ukuze kuqinisekiswe ukuthi ukukhishwa kwawo kwemisebe kungaphakathi kwemikhawulo ephephile, okuvikela abasebenzisi ezingozini ezingaba khona.
Ekuphetheni
Njengamadivaysi amaningi e-elekthronikhi, amaswishi enethiwekhi akhipha izinga elithile lemisebe kagesi, ngokuyinhloko esesimweni semisebe yezinga eliphansi engeyona i-ionizing. Kodwa-ke, le misebe ingaphakathi kwemingcele ephephile ebekwe izindinganiso zokulawula futhi ayizange ixhunywe nemiphumela emibi yezempilo. Abasebenzisi bangasebenzisa amaswishi enethiwekhi njengengxenye yenethiwekhi yabo yasekhaya noma yebhizinisi ngokuzethemba, bazi ukuthi amadivayisi aklanyelwe ukusebenza ngokuphephile nangempumelelo. Kwa-Todahike, sizibophezele ekuhlinzekeni izixazululo zenethiwekhi zekhwalithi ephezulu ezithobela izindinganiso zokuphepha, ukuqinisekisa ukusebenza okuthembekile nokuthula kwengqondo kumakhasimende ethu.
