I-Optical Fiber Communication
Ubuchwepheshe bokuxhumana nge-fiber optical buqhamuke ekuxhumaneni kwe-optical futhi sebungenye yezinsika eziyinhloko zokuxhumana zesimanje. Idlala indima ebalulekile ezinkundleni zokuxhumana zesimanje.Njengobuchwepheshe obusafufusa, ukuxhumana kwe-fiber optical kuye kwathuthuka ngokushesha eminyakeni yamuva futhi isetshenziswa kabanzi emlandweni wokuxhumana. Kuphinde kube wuphawu olubalulekile lwenguquko entsha yezobuchwepheshe emhlabeni kanye nethuluzi eliyinhloko lokudlulisela ulwazi oluhlukahlukene emphakathini wolwazi wesikhathi esizayo.
Izici zokuxhumana nge-fiber optical
1.Umthamo wolwazi we-Broadband mkhulu
Umthamo wokuxhumana we-fiber optical bukhulu, futhi ububanzi bokudlulisela kwe-fiber optical bukhulu kakhulu kunobubanzi bekhebula noma intambo yethusi. Kodwa-ke, ohlelweni lwe-fiber optical ene-wavelength eyodwa, njengoba idivayisi yokugcina ilinganiselwe kakhulu, ububanzi bokudlulisa kwe-fiber optical ngokuvamile abuboniswa. Ngakho-ke, amasu esayensi ayadingeka ukukhulisa amandla okudlulisela.
2.Ukulahlekelwa okuphansi, kungadluliselwa ngokuhamba amabanga amade
Izinga lokulahlekelwa kokuxhumana kwe-fiber optical liphansi kakhulu kunezinga elivamile lokulahlekelwa kokuxhumana. I-fiber optical ayigcini nje ngokulahlekelwa okuncane, kodwa futhi ingakwazi ukuxhumana namabanga amade. Ibanga elide kakhulu lokuxhumana lingafinyelela ngaphezu kwamamitha ayi-10,000, ngakho ukuxhumana nge-fiber optical kusebenza kakhulu ezinkundleni zokuxhumana. Indawo lapho inani lolwazi liqhathaniswa khona kanye nezindleko zokuxhumana ze-fiber-optic ziphezulu uma kuqhathaniswa, ngokuvikeleka okuhle.
3.Ukuphazanyiswa okuqinile kwe-anti-electromagnetic
I-optical fibre ngokuyinhloko iyisivikeli esiyisivikelo esenziwe nge-quartz njengempahla eluhlaza, futhi impahla ihamba kahle kakhulu ekugqumeni futhi ayigqwali kalula.Isici esibaluleke kakhulu sokuxhumana kwe-fiber optical amandla ayo aqinile e-anti-electromagnetic interference, futhi akunjalo. ithintwa umsebenzi we-sunspot yemvelo, izinguquko ze-ionospheric kanye nokuphazanyiswa kombani, futhi ayikho ngaphansi kokuphazanyiswa kozibuthe okwenziwa ngugesi.Futhi ukuxhumana kwe-fiber optical kungabuye kuhlanganiswe nomqhubi wamandla ukuze kwakhe ikhebula lemigqa emibili optical noma parallel ne-high-voltage. ulayini wamandla. Lesi sici sokuxhumana kwe-fiber optical sidlala indima enkulu ohlelweni lokuxhumana emkhakheni wamandla kagesi aqinile. Ukuxhumana kwamandla okukhanya nakho kungasetshenziswa kwezempi ngoba kungakhululeka ekuphazamisekeni kwe-electromagnetic pulse.
4.Ukuvikeleka okuhle nokugcinwa kuyimfihlo
Ekudluliselweni kwamagagasi omsakazo esikhathini esidlule, njengoba amaza kazibuthe kagesi evuza phakathi nenqubo yokudlulisela, ukuphazamiseka kwezinhlelo ezihlukahlukene zokudlulisela kuyabangwa, futhi ukugcinwa kuyimfihlo akukuhle.Nokho, ukuxhumana kwe-optical fiber ikakhulukazi kusebenzisa amaza okukhanya ukuze kudluliselwe amasignali. Amasignali okubona avalelwe ngokuphelele esakhiweni se-optical waveguide, kanti eminye imisebe evuzayo imuncwa umgodla wangaphandle we-fiber optical, ngisho nendandatho enesimo esibi noma ikhona. Kukhona nokuvuza kwamagagasi okukhanya okumbalwa. Ngaphezu kwalokho, ngesikhathi sokuxhumana nge-fiber optical, izintambo eziningi ze-fiber optical zingafakwa ekhebulani elilodwa lokukhanya ngaphandle kokuphazanyiswa. Ngakho-ke, ukuxhumana kwe-fiber optical kunekhono eliqinile lokulwa nokuphazamiseka kanye nokugcinwa kuyimfihlo, futhi ukusebenza kokuphepha kokuxhumana kwe-optical fiber nakho kuphezulu kakhulu.
