Karolo ea li-node tsa optical marangrang a puisano a sejoale-joale

Mehleng ena ea dijithale, tlhoko ea inthanete e potlakileng le lits'ebeletso tsa puisano tse tsoetseng pele ha e so ka e e-ba kholo ho feta leha e le neng pele. Ho fihlela tlhoko ena, lik'hamphani tsa puisano li ntse li ntlafatsa marang-rang a tsona khafetsa ho fa bareki likhokahano tse potlakileng le tse tšepahalang haholoanyane. Karolo ea bohlokoa marang-rang ana a puisano ea sejoale-joale ke leqhubu la optical.

Li-node tsa mahloke lintlha tsa bohlokoa marangrang a faeba ea optical a sebetsanang le ho aba matšoao a optical. E sebetsa joaloka borokho pakeng tsa marangrang a faeba ea optical le marangrang a tloaelehileng a cable ea coaxial, e lumellang phetiso ea matšoao a data a lebelo le phahameng, lentsoe le video. Li-node tsa optical li bohlokoa ho netefatsa hore matšoao ana a fanoa ka katleho le ka nepo libakeng tseo a reretsoeng ho li fihlela.

Dinode tsa mahlo di bapala karolo ya bohlokwa ho faneng ka ditshebeletso tsa boleng bo hodimo tse kang thelevishene e nang le tlhaloso e hodimo, inthanete e potlakileng haholo le ditshebeletso tsa difouno tsa dijithale. Ka ho fetola matshwao a mahlo hore e be matshwao a motlakase le ka tsela e fapaneng, dinode tsa mahlo di thusa ho fetisa data ka tsela e se nang sekoli hodima marangrang. Tshebetso ena e dumella phetiso ya data e ngata ka lebelo le makatsang, e dumella basebedisi ho phallela divideo, ho jarolla difaele, le ho etsa mehala ya mohala ka nako e fokolang.

Ntle le ho fetisa matshwao, di-node tsa optical di boetse di sebetsa e le dintlha tsa taolo le tsamaiso ka hara netweke. E na le di-elektroniki tse tswetseng pele le software tse thusang basebetsi ba netweke ho beha leihlo le ho fetola phallo ya data ho netefatsa tshebetso e ntle le botshepehi. Boemo bona ba taolo bo bohlokwa ho bolokeng boleng ba tshebeletso bakeng sa basebedisi ba ho qetela le ho rarolla mathata afe kapa afe a ka hlahang netwekeng.

Ho phaella moo, di-node tsa optical di bapala karolo ya bohlokwa ho atoloseng ho kwahelwa ha marangrang a fiber optic. Di-node tsa fiber di ka hokahanya malapa le dikgwebo le marangrang a fiber optic a lebelo le hodimo ka ho sebetsa jwalo ka dikgoro pakeng tsa marangrang a fiber optic le coaxial. Ho kwahelwa ha marangrang a atolositsweng ho bohlokwa ho faneng ka ditshebeletso tse tswetseng pele tsa puisano ho baahi ba bangata.

Ha mahlale a macha a ntse a tsoela pele ho hlaha 'me tlhoko ea litšebeletso tsa Inthanete tse potlakileng le tsa puisano tse tsoetseng pele e ntse e hola, karolo ea li-node tsa optical marangrang a puisano a sejoale-joale e ntse e e-ba ea bohlokoa haholo. Li-node tsa optical li na le bokhoni ba ho sebetsana le ho aba matšoao a optical, ho fana ka mesebetsi ea taolo le tsamaiso, le ho atolosa ho koaheloa ha marang-rang. Ke likarolo tsa bohlokoa bakeng sa ho fana ka litšebeletso tsa puisano tsa boleng bo holimo le tse potlakileng.

Ho phethela,li-node tsa mahloke karolo ea bohlokoa ea marangrang a puisano ea sejoale-joale 'me a bapala karolo ea bohlokoa phetisong, taolong le katolosong ea lits'ebeletso tsa puisano tse potlakileng. Ha tlhoko ea lits'ebeletso tse tsoetseng pele tsa dijithale e ntse e tsoela pele ho hola, bohlokoa ba li-node tsa optical ho nolofatseng phano ea lits'ebeletso tsena bo ke ke ba feteletsoa. ​​Ke karolo ea bohlokoa ho netefatseng hore basebelisi ba fumana lits'ebeletso tsa inthanete tse potlakileng, tsa thelevishene le tsa mohala tsa boleng bo holimo, e leng se etsang hore e be karolo ea bohlokoa ea meralo ea motheo ea puisano ea sejoale-joale.
