Njengomhlinzeki ochwepheshe wezinto zekhebula,IZWE ELILODWAinikeza uhla oluphelele lwezinto zokusetshenziswa zekhebula le-optical, okuhlanganisa i-fiber optical yemodi eyodwa esezingeni eliphezulu. Njengendlela yokudlulisa eyinhloko yamanethiwekhi okuxhumana anamuhla, i-fiber yemodi eyodwa isetshenziswa kabanzi ezinhlelweni zokuxhumana zebanga elide kanye nesivinini esikhulu ngenxa yobubanzi bayo obuphezulu, ukuncipha okuphansi, kanye nebanga lokudlulisa elide.
Kulesi sihloko, sihlola izici ze-wavelength kanye nokudluliselwa kwemodi eyodwai-fiber ebonakalayongokombono wezinto ezibonakalayo, okunikeza ukuqonda okuwusizo kokukhethwa kwezinto kanye nokukhiqizwa kwezintambo.
1. Isakhiwo Esiyisisekelo Se-Single-Mode Optical Fiber
I-fiber optical yemodi eyodwa iqukethe umongo kanye ne-cladding. Inkomba yokukhanya kwe-core iphakeme kuneyomongo, okuvumela ukukhanya ukuthi kusakazeke ngokukhanya kwangaphakathi okuphelele ngaphakathi komongo. Lesi sakhiwo sisekela imodi eyodwa kuphela yokusabalalisa (imodi eyisisekelo), siqeda ngempumelelo ukuhlakazeka kwe-modal futhi sithuthukise ikhwalithi yokudlulisela.
Ububanzi be-core buvame ukusuka kuma-micrometer amaningana kuya ku-10 μm, kuyilapho ububanzi be-cladding bungaba ngu-125 μm.
2. Ukubaluleka Kobude Begagasi
Ubude bamagagasi budlala indima ebalulekile ekuxhumaneni ngefayibha ye-optical. Amafasitela okudlulisa asetshenziswa kakhulu ahlanganisa:
Ibhendi ye-O (1260–1360 nm)
Ibhendi ye-C (1530–1565 nm)
Ibhendi le-L (1565–1625 nm)
Ngaphakathi kwalezi zigaba zamaza okukhanya, imicu ye-optical ibonisa ukusebenza okuhle kakhulu kokudlulisa. Phakathi kwazo, i-C-band ine-attenuation ephansi kakhulu (ephansi cishe njenge-0.2 dB/km), okwenza kube yifasitela eliyinhloko lokusebenza kwezinhlelo zokuxhumana ze-optical ezikude nezisheshayo.
3. Izici Zokudlulisa Eziyinhloko
Isilinganiso Sokunciphisa:
I-attenuation coefficient, elinganiswa ku-dB/km, iyipharamitha eyinhloko esetshenziselwa ukuhlola ukulahleka kokudluliselwa. Ibangelwa kakhulu ukumuncwa kwezinto kanye nokuhlakazeka kwazo. Ku-C-band, attenuation ingaba phansi cishe ku-0.2 dB/km, kuyilapho iphakeme kancane ku-O-band.
I-fiber optical yemodi eyodwa enikezwa yi-ONE WORLD ikhiqizwa kusetshenziswa izinto ezihlanzekile kakhulu kanye nezinqubo ezizinzile, okuqinisekisa ukusebenza okuzinzile kokuncishiswa ngaphakathi kwemininingwane ejwayelekile yokudluliselwa okuthembekile kwebanga elide.
Izici Zokuhlakazeka:
Ukuhlakazeka kubhekisela ekwehlukeni kwesivinini sokusabalala kokukhanya kuma-wavelength ahlukene, okuholela ekwandiseni isignali. Ngokwenza ngcono ukwakheka kwezinto kanye nokwakheka kwesakhiwo, imicu ingaklanywa ngezakhiwo ezahlukene zokuhlakazeka ukuze ihlangabezane nezidingo zokuxhumana ezahlukahlukene.
Ubude beWavelength obunqunyiwe:
I-wavelength enqunyiwe yi-wavelength encane lapho ukudluliselwa kwemodi eyodwa kungagcinwa khona, ngokuvamile kububanzi obungu-1260–1300 nm. Ngaphansi kwaleli nani, izindlela ze-oda eliphezulu zingasakazeka, zithinte ukuzinza kwesignali. I-ONE WORLD ilawula ngokuqinile i-wavelength enqunyiwe ukuqinisekisa ukusebenza okuzinzile kwemodi eyodwa ngaphakathi kwebanga lokusebenza elibekiwe.
Ububanzi Bensimu Yemodi (MFD):
Ububanzi bensimu yemodi buchaza ukusatshalaliswa kwensimu ye-optical ku-fiber core futhi kuthinta ukusebenza kahle kokuxhumanisa kanye nokusebenza kokuxhuma. Imininingwane ehlukene ye-MFD iyatholakala ukuze ihlangabezane nezidingo ezahlukene zokuklama uhlelo kanye nokupakisha.
4. Ukuthuthukisa Ukusebenza Kokudlulisa
Ukusebenza kokudlulisa kwe-fiber optical yemodi eyodwa kungathuthukiswa kakhulu ngokwenza ngcono ubumsulwa bezinto kanye nezinqubo zokukhiqiza ezifana ne-MCVD (Modified Chemical Vapor Deposition). Lokhu kuthuthukiswa kusiza ekunciphiseni ukumuncwa kokungcola kanye nokukhubazeka kwesakhiwo, okuholela ekunciphiseni ukuncipha kanye nezici zokuhlakazeka ezingcono.
I-ONE WORLD ilandela njalo intuthuko yemboni futhi isebenzisane eduze nabalingani abathembekile abaphezulu ukuze banikeze imikhiqizo ye-optical fiber ezinzile nesezingeni eliphezulu.
5. Isiphetho
Izici zobude besikhathi kanye nokudluliselwa kwe-fiber optical yemodi eyodwa kunquma ngqo ukusebenza kwezinhlelo zokuxhumana ze-optical. Ukuqonda okucacile kwalezi zinhlaka ezibalulekile kusiza ukuthuthukisa ukwakheka kwenethiwekhi ye-fiber futhi kuhlangatshezwane nesidingo esikhulayo sokudluliselwa kwedatha okusheshayo nomthamo ophezulu.
Njengomlingani othembekile ezintweni zekhebula, i-ONE WORLD izibophezele ekuhlinzekeni nge-fiber optical yemodi eyodwa ezinzile nethembekile ukusekela amaphrojekthi akho okuxhumana. Zizwe ukhululekile ukuxhumana nathi ukuthola ulwazi olwengeziwe lomkhiqizo kanye nokusekelwa kobuchwepheshe.
