Ikhebula le-fiberubuchwepheshe, okuhlanganisaikhebula le-fiber optic le-tube elikhululekile, iguqule ukuxhumana kwe-inthanethi ngokuletha isivinini nokuthembeka okungenakuqhathaniswa. Phakathi kuka-2013 no-2018, imboni ikhule ngesilinganiso sonyaka esihlanganisiwe se-11.45%, kanti ukubikezela kufinyelela ku-12.6% ngo-2022Ukwandaisidingo sokubambezeleka okuphansi kanye nokuxhumeka kwedivayisi okungenamthungokugqamisa ukubaluleka kokubiliikhebula le-fiber optic lemodi eyodwafuthiikhebula le-fiber optic elinamamodi amaningiekwakheni ikusasa ledijithali. Ngaphezu kwalokho, ukwanda kwecizinketho zinegalelo ekuthuthukisweni kwalolu buchwepheshe.
Izinto Ezibalulekile Okufanele Uzicabangele
- Izintambo zefayibha ziyasheshafuthi zithwala idatha eningi kunezethusi. Zilungele ukusetshenziswa kwe-inthanethi yanamuhla.
- I-fiber ekhethekile engagobi yenza kube lula ukusetha ezindaweni ezincane. Isebenza kangcono ezindaweni eziqinile.
- Izintambo ezintsha zefayibha ezinobungani nemvelosebenzisa izinto eziluhlaza ukusiza iplanethi. Zisekela ubuchwepheshe obuhlanzekile.
Isimo Samanje Sobuchwepheshe Bekhebula Le-Fiber
Izinzuzo Zekhebula Le-Fiber Kunezintambo Zethusi
Ubuchwepheshe bekhebula le-fibre bunikeza izinzuzo ezibalulekile kunezintambo zethusi zendabuko, okwenza kube ukukhetha okuthandwayo kokuxhumana kwesimanje. Enye yezinzuzo eziphawuleka kakhulu ikhono layo lokudlulisa idatha ebangeni elide ngaphandle kokuwohloka kwesignali. Ngokungafani nezintambo zethusi, ezithola ukuncishiswa okuphezulu, izintambo ze-fibre zigcina amandla esignali, ziqinisekisa ukusebenza okuthembekile. Ngaphezu kwalokho, izintambo ze-fibre zinikeza i-bandwidth ephezulu kakhulu, zisekela isidingo esikhulayo sezinhlelo zokusebenza ezidinga idatha eningi njengokusakaza ividiyo kanye nokubala amafu.
Enye inzuzo ebalulekile ilele ekungavikelekeni kwazo ekuphazamisekeni kwe-electromagnetic (EMI). Izintambo zethusi zisengozini ye-EMI, okungaphazamisa ukudluliswa kwedatha. Izintambo ze-fibre, ngakolunye uhlangothi, zisebenzisa ukukhanya ukudlulisa idatha, okwenza zimelane nokuphazamiseka okunjalo. Lesi sici siqinisekisa ukuxhumana okuqhubekayo nokuphephile, ngisho nasezindaweni ezinomsindo omkhulu kagesi. Ngaphezu kwalokho, izintambo ze-fibre ziqinile futhi zilula, okunciphisa izinselele zokufakwa nokugcinwa.
Izici Zokushayela Amanethiwekhi Ezintambo Zezintambo Zesimanje
Amanethiwekhi ekhebula le-fiber yesimanje achazwa izici zawo ezithuthukisiwe, ezithuthukisa ukusebenza nokuthembeka. Esinye isici esinjalo ukusetshenziswa kwama-fiber ane-bandwidth ephezulu. Isibonelo,I-fiber engama-micron angu-50 isekela i-bandwidth engu-500 MHz-km, ihlangabezana nezidingo zokuxhumana zesimanje, kuyilapho i-fiber engu-62.5-micron inikeza i-160 MHz-km yezinhlelo zokusebenza ze-FDDI-grade. Lokhu kuthuthuka kwenza kube lula ukudluliselwa kwedatha okusheshayo nokuphumelelayo.
Esinye isici esishukumisayo ukuthuthukiswa kwemicu engazweli ukugoba. Le micu igcina ukusebenza ngisho noma igobile ngama-engeli abukhali, okwenza ibe yindawo ekahle yokufakwa okuyinkimbinkimbi. Ngaphezu kwalokho, ukusungula izinto ezintsha ekumbozweni kwemicu nezinto zokwakha kuye kwathuthukisa ukuqina, okuqinisekisa ukusebenza kwesikhathi eside.Izinkampani ezifana noDowellziphambili kulezi ntuthuko, ziletha izixazululo ezisezingeni eliphezulu ezihlangabezana nezidingo zezindawo zedijithali ezishintshayo.
Amathrendi Ekhebula Le-Fiber Avelayo ngo-2025
I-Fiber Yokulahlekelwa Okuphansi Kakhulu: Ukukhulisa Ukusebenza Kahle Kwesignali
Ubuchwepheshe befayibha yokulahlekelwa okuphansi kakhulu bubeka amazinga amasha okusebenza kahle kwesignali. Ngokunciphisa ukulahleka kwesignali yokukhanya, lokhu kusungulwa kwenza idatha ikwazi ukuhamba amabanga amade ngaphandle kokuwohloka. Lokhu kuthuthuka kuthuthukisa kakhulu i-isilinganiso sesignali-kuya-kumsindo (i-OSNR), ukuqinisekisa ukuxhumana okucacile nokuthembekile. Ngaphezu kwalokho, imicu yokulahlekelwa ephansi kakhulu isekela amazinga aphezulu edatha, okuhlanganisa i-100 Gbit/s, i-200 Gbit/s, kanye ne-400 Gbit/s, okwenza kube kuhle kakhulu ezinhlelweni zokusebenza ze-inthanethi ezisheshayo. Ukusebenza okuthuthukisiwe kokudlulisa kunciphisa nesidingo sokukhulisa isignali, kunciphisa izindleko zokusebenza kwabahlinzeki benethiwekhi.
