Iifiber ze-Optical zizitshaneli ezinengcingo ezithumela imiqondiso yokukhanya.
Sibhekisela kwiimpawu zombane ezingeyomfuneko kwitshaneli njengengxolo. Ingxolo kwinkqubo yonxibelelwano igxininisekile kwisiginali, kwaye kukho ingxolo kwinkqubo yonxibelelwano xa kungekho mqondiso wothumelo, kwaye ingxolo ihlala ikhona kwinkqubo yonxibelelwano. Ingxolo inokubonwa njengohlobo lokuphazamiseka kwisitishi, ekwabizwa ngokuba yi-additive interference, kuba ibekwe phezulu kwisiginali. Ingxolo iyingozi ekugqithiseni umqondiso, inokugqwetha imiqondiso ye-analog, yenze iimpazamo kwimiqondiso yedijithali, kwaye icuthe izinga losasazo lolwazi.
Ngokohlelo lwemithombo, ingxolo inokwahlulwa ibe ziindidi ezimbini: ingxolo eyenziwe ngabantu kunye nengxolo yendalo. Ingxolo yeAnthropogenic yenziwa yimisebenzi yabantu, efana nentlantsi ephuma kwizibhobho zombane kunye nombane odlulayo.iiswitshi, intlantsi evela kwiinkqubo zokulayita iimoto, uphazamiseko oluvela kwizibane ezizibane, kunye nemitha yemitha yombane evela kwezinye izikhululo zikanomathotholo kunye nezixhobo zombane. Ingxolo yendalo ziintlobo ngeentlobo zemitha yemitha ye-electromagnetic ekhoyo kwindalo, efana nombane (ukukhanya), ingxolo ye-atmosphere, kunye ne-cosmicnoise evela elangeni nakumnyele (galaxy). Ukongeza, kukho ingxolo yendalo ebaluleke kakhulu, oko kukuthi, ingxolo ye-thermal. Ingxolo yobushushu ivela kwintshukumo ye-thermal yee-electron kuwo onke amacandelo aphikisayo. Ngokomzekelo, iingcingo, i-resistors, kunye nezixhobo ze-semiconductor zonke zivelisa ingxolo ye-thermal. Ke ngoko, ingxolo yobushushu ikuyo yonke indawo kwaye ngokungenakuthintelwa ikhona kuzo zonke izixhobo zombane, ngaphandle kokuba isixhobo sikwiqondo lobushushu le-thermodynamic Kulungile. Kwizinto ezixhathisayo, ii-electron zamahhala zihamba rhoqo ngenxa yamandla abo ashushu, zingqubuzana namanye amasuntswana ahambayo kwaye zihamba ngokungenamkhethe kwindlela yepolygonal, oko kukuthi, kubonakala njengentshukumo yeBrownian. Ukungabikho kwamandla angaphandle, umyinge wangoku ovela kwintshukumo ye-Brownian yezi electron ilingana no-zero, kodwa icandelo langoku le-AC liyenziwa. Eli candelo le-AC libizwa ngokuba yingxolo eshushu. Uluhlu lokuphindaphinda kwengxolo eshushu lubanzi kakhulu, lusasazwa ngokulinganayo malunga nokusuka kufutshane neqanda ukuya kuthi ga kwi-102Hz.
Le yi-Shenzhen HDV phoeletron Technology Ltd. ukuzisa malunga nenqaku elithi "ingxolo kwisitishi", ithemba lokukunceda, i-Shenzhen HDV phoeletron Technology Ltd. yimveliso ekhethekileyo yabenzi bezixhobo zonxibelelwano, iimveliso zonxibelelwano ezishushu zenkampani zezi:I-ONUuthotho, uthotho lwe-transceiver,OLTseries, kodwa kwakhona imveliso yothotho imodyuli, ezifana: Unxibelelwano imodyuli optical, imodyuli yonxibelelwano optical, network imodyuli optical, imodyuli yonxibelelwano optical, imodyuli ifayibha optical, Ethernet imodyuli ifayibha optical, njl., inokubonelela ngenkonzo ehambelanayo esemgangathweni kubasebenzisi abahlukeneyo ' iimfuno, wamkele utyelelo lwakho.
