Umgaqo wonxibelelwano obonakalayo
Umgaqo wonxibelelwano umi ngolu hlobo lulandelayo.Ekupheleni kokuthumela, ulwazi olugqithisiweyo (njengelizwi) kufuneka luguqulwe kuqala lube yimiqondiso yombane, emva koko imiqondiso yombane iguqulelwe kwintsimbi yelaser ekhutshwa yilaser (umthombo wokukhanya), ukuze ubukhulu bokukhanya buhluka kunye ne-amplitude (i-frequency) yezibonakaliso zombane kunye nomgaqo wokubonakalisa ukukhanya okupheleleyo, isignali ye-optical idluliselwa kwi-fiber optical.Ngenxa yokulahleka kunye nokusabalalisa i-fiber optical, isibonakaliso sokukhanya siya kuba iyancipha kwaye igqwethekile emva kokusasazwa kumgama.Isibonakaliso esincitshisiweyo sandiswa kwi-repeater optical ukulungisa i-waveform ephosakeleyo.Ekupheleni kokufumana, umtshini ufumana isignali ye-optical kwaye uyiguqule kwisignali yombane, echithwayo ukubuyisela ulwazi lokuqala.
Iinzuzo zokuhanjiswa kwefayibha zamehlo:
● Umthamo omkhulu wonxibelelwano, umgama omde wonxibelelwano, uvakalelo oluphezulu, kwaye akukho kuphazamiseka kwingxolo
● Ubungakanani obuncinci, ubunzima obulula, ubomi obude, umgangatho omhle kunye nexabiso eliphantsi
● I-Insulation, ukumelana noxinzelelo oluphezulu, ukushisa okuphezulu, ukubola, ukuguquguquka okunamandla
● Imfihlo ephezulu
● Imathiriyeli ekrwada etyebileyo namandla aphantsi: Eyona nto isisiseko yokwenza i-quartz fiber yisilica, eyisanti, nesanti yi-abun.
Unxibelelwano lwefiber ye-Optical fiber luqulunqwe luluhlu lwezixhobo zonxibelelwano lwamehlo.dant ngokwendalo, ngoko ixabiso layo lisezantsi.Izixhobo zeOptical zihlelwa ngokwezixhobo ezisebenzayo kunye nezixhobo ezingasebenziyo.Isixhobo esibonakalayo esisebenzayo sisixhobo esiphambili kwinkqubo yonxibelelwano lwamehlo ukuguqula isixhobo Umqondiso wombane ube ngumqondiso wokukhanya okanye ukuguqula umqondiso wokukhanya ube ngumqondiso wombane, kwaye yintliziyo yenkqubo yothumelo lombane. Amalungu e-Optical passive zizixhobo ezifuna umlinganiselo othile wamandla kwiinkqubo zonxibelelwano lwamehlo kodwa azinawo umbane wokufota okanye i-electro- uguqulo lwe-optic.Ziyi-nodes eziphambili zeenkqubo zokuhanjiswa kwe-optical, kubandakanywa izixhumi ze-fiber optic, i-wavelength division multiplexers, i-splitters optical, kunye ne-optical switches., ii-optical circulators kunye ne-optical isolator.
● Iintambo zeFiber optic patch (ekwaziwa ngokuba ziziqhagamshelo zefayibha optic) zibhekisa kwiiplagi zokuqhagamshela kuzo zombini iziphelo zentambo yoqhagamshelwano olusebenzayo lwendlela.Iplagi kwelinye icala ibizwa ngokuba yi-pigtail.
● I-Wavelength division multiplexer (WDM) idibanisa uluhlu lweempawu ze-optical kunye ne-wavelengths eyahlukeneyo kwaye ihambisa kunye ne-fiber optical fiber.Ubuchule bonxibelelwano apho imiqondiso ye-optical ye-wavelengths eyahlukeneyo yahlulwe ngeendlela ezithile ekupheleni kokufumana.
● I-Optical splitter (eyaziwa ngokuba yi-splitter) iyisixhobo se-fiber-optic tandem esinamagalelo amaninzi kunye neziphumo ezininzi.Ngokomgaqo wokwahlula, i-optical splitter inokwahlulwa ibe ziindidi ezimbini: uhlobo lwe-taper etyhidiweyo kunye nohlobo lwe-waveguide olucwangcisiweyo ( Uhlobo lwe-PLC).
● Ukutshintsha kwamehlo sisixhobo sokutshintsha okubonakalayo, esisisixhobo esibonakalayo esinezibuko lothumelo olunokuzikhethela.Umsebenzi wayo kukutshintsha ngokomzimba okanye ngokufanelekileyo imiqondiso ye-optical kwimigca yokuhambisa optical okanye iindlela ezidibeneyo zokukhanya.
● I-Optical circulator sisixhobo se-multi-port optical esineempawu ezingezizo.
● Xa isignali ye-optical ingena nakweyiphi na i-port, iphuma kwi-port elandelayo kunye nelahleko encinci kwi-oda yedijithali.Ukuba isignali ifakwe kwi-port 1, inokukhutshwa kuphela kwi-port 2. Ngokufanayo, ukuba uphawu lufakwe kwi-port 2, lunokukhutshwa kuphela kwi-port 3.
● I-optical isolator sisixhobo sokukhanya esivumela ukukhanya okukodwa kuphela ukuba kudlule kwaye sikuthintele ukuba kudlule kwelinye icala.Umgaqo wayo wokusebenza usekelwe kwi-non-reciprocity of Faraday rotation.
