    Melao-motheo le melemo ea puisano ea fiber optical ke efe? Tlhaloso ea lisebelisoa tsa optical communication passive

    Nako ea poso: Aug-09-2019

    Molao-motheo oa puisano optical

    Molao-motheo oa puisano ke ka tsela e latelang.Qetellong ea ho romela, boitsebiso bo fetisitsoeng (joaloka lentsoe) bo lokela ho fetoloa pele ho lipontšo tsa motlakase, ebe lipontšo tsa motlakase li fetotsoe ho beam ea laser e hlahisoang ke laser (mohloli oa leseli), e le hore ho be le leseli. matla a khanya a fapana le amplitude (frequency) ea matšoao a motlakase 'me ka molao-motheo oa ho bonahatsa khanya ka ho feletseng, pontšo ea optical e fetisoa ka fiber optical.Ka lebaka la tahlehelo le ho hasana ha fiber ea optical, pontšo ea optical e tla ba teng. tsielehile le ho sotha ka mora ho fetisoa hole. Letšoao le fokolisitsoeng le matlafatsoa ho optical repeater ho lokisa sebopeho se sothehileng sa waveform. Qetellong ea ho amohela, mochine o amohela letšoao la optical ebe o o fetola letšoao la motlakase, le fokotsoang ho tsosolosa tlhahisoleseding ea pele.

    Melemo ea phetisetso ea fiber ea optic:

    ● Bokhoni bo boholo ba puisano, sebaka se selelele sa puisano, kutloisiso e phahameng, 'me ha ho tšitiso ea lerata

    ● Boholo bo nyane, boima bo bobebe, bophelo bo bolelele, boleng bo botle le theko e tlase

    ● Insulation, khatello e phahameng ea khatello, mocheso o phahameng, kutu, ho ikamahanya le maemo ho matla

    ● Lekunutu le phahameng

    ● Lisebelisoa tse tala le bokhoni bo fokolang: Ntho e ka sehloohong e sebelisoang ho etsa fiber ea quartz ke silika, e leng lehlabathe, 'me lehlabathe ke abun.

    Optical fiber communication e entsoe ka letoto la lisebelisoa tsa puisano tsa optical.tant ka tlhaho, kahoo theko ea eona e tlase.Lisebelisoa tsa Optical li arotsoe ka lisebelisoa tse sebetsang le lisebelisoa tse sa sebetseng.Sesebelisoa se sebetsang sa optical ke sesebelisoa sa bohlokoa tsamaisong ea puisano ea optical bakeng sa ho fetola mochine. lets'oao la motlakase hore le be lets'oao la optical kapa ho fetolela lets'oao la optical hore e be lets'oao la motlakase, 'me ke pelo ea sistimi ea optical transmission. optic phetoho. Ke li-node tsa bohlokoa tsa sistimi ea phetisetso ea optical, ho kenyeletsoa lihokelo tsa fiber optic, li-multiplexers tsa karohano ea wavelength, li-splitter tsa optical, le optical.li-switches. , li-circulator tsa optical le li-isolators tsa optical.

    ● Lithapo tsa fiber optic patch (tse tsejoang hape e le lihokelo tsa fiber optic) li bua ka likhokello tsa likhokahano lipheletsong tse peli tsa thapo bakeng sa khokahanyo ea optical path active.Polaka e ntlheng e 'ngoe e bitsoa pigtail.

    ● Wavelength division multiplexer (WDM) e kopanya letoto la lipontšo tsa optical tse nang le mefuta e sa tšoaneng ea maqhubu 'me e li fetise ka fiber e le' ngoe ea optical. Mokhoa oa puisano oo mats'oao a optical a maqhubu a fapaneng a arohaneng ka mekhoa e itseng pheletsong ea ho amohela.

    ● Optical splitter (eo hape e tsejoang e le splitter) ke sesebelisoa sa fiber-optic tandem se nang le lisebelisoa tse ngata le lihlahisoa tse ngata. mofuta oa PLC).

    ● Opticalswitjhake sesebelisoa sa optical switching, e leng sesebelisoa sa optical se nang le likou tse le 'ngoe kapa ho feta tse ikhethileng tsa phetisetso. Mosebetsi oa eona ke ho 'meleswitjhakapa ka mokhoa o utloahalang sebelisa matšoao a optical meleng ea optical transmission kapa litsela tse kopantsoeng tsa optical.

    ● Optical circulator ke sesebelisoa sa multi-port optical se nang le litšobotsi tse sa tsitsang.

    ● Ha lets'oao la optical le kentsoe ho tsoa koung efe kapa efe, le hlahisoa ho tsoa koung e latelang ka tahlehelo e nyane ka tatellano ea dijithale. Haeba lets'oao le tsoa ho port 1, le ka hlahisoa feela ho tsoa ho port 2. Ka mokhoa o ts'oanang, haeba lets'oao le kentsoe ho tsoa ho port 2, le ka hlahisoa feela ho tsoa ho port 3.

    ● Optical isolator ke sesebelisoa sa passive optical se lumellang feela leseli le sa lebelloang ho feta le ho le thibela ho feta ka lehlakoreng le fapaneng. Molao-motheo oa eona oa ts'ebetso o ipapisitse le ho se lumellane ha ho potoloha ha Faraday.
