Njengomthengisi oqeqeshiweyo wezixhobo zekhebula,IHLABATHI ELINYEibonelela ngoluhlu olupheleleyo lwezinto ezikrwada zekhebula le-optical, kuquka i-fiber ye-optical ye-single-mode ekumgangatho ophezulu. Njengendlela ephambili yokudlulisela umbane kwiinethiwekhi zonxibelelwano zanamhlanje, i-fiber ye-single-mode isetyenziswa kakhulu kwiinkqubo zonxibelelwano ezikude nezikhawulezayo ngenxa ye-bandwidth yayo ephezulu, ukuncipha okuphantsi, kunye nomgama wokudlulisela umbane omde.
Kule nqaku, sihlola ubude be-wavelength kunye neempawu zokudluliselwa kwemowudi enyeifayibha ye-opticalngokwembono yezinto eziphathekayo, enika ulwazi oluluncedo malunga nokukhethwa kwezinto kunye nokwenziwa kweentambo.
1. Ulwakhiwo oluSisiseko lweFiber ye-Optical yeMode enye
I-fiber ye-optical yemo enye iqulathe i-core kunye ne-cladding. I-refractive index ye-core iphezulu kune-cladding, ivumela ukukhanya ukuba kusasazeka ngokukhanya kwangaphakathi ngaphakathi kwe-core. Olu lwakhiwo luxhasa imo enye kuphela yokusasazwa (imo yesiseko), ephelisa ngempumelelo ukusasazeka kwe-modal kunye nokuphucula umgangatho wokusasazwa.
Ububanzi be-core budla ngokuba phakathi kwee-micrometers eziliqela ukuya kuthi ga kwi-10 μm, ngelixa ububanzi be-cladding bumalunga ne-125 μm.
2. Ukubaluleka kobude beWavelength
Ubude be-wavelength budlala indima ebalulekileyo kunxibelelwano lwe-optical fiber. Iifestile zokudlulisa ezisetyenziswa kakhulu ziquka:
Ibhendi ye-O (1260–1360 nm)
Ibhendi ye-C (1530–1565 nm)
Ibhendi ye-L (1565–1625 nm)
Ngaphakathi kwezi zigaba zamaza ombane, iifayibha ze-optical zibonisa ukusebenza kakuhle kothumelo. Phakathi kwazo, i-C-band ine-attenuation ephantsi (ephantsi njenge-0.2 dB/km), nto leyo eyenza ukuba ibe yeyona festile iphambili yokusebenza kwiinkqubo zonxibelelwano lwe-optical ezikude nezikhawulezayo.
3. Iimpawu eziphambili zoThutho
I-Attenuation Coefficient:
I-attenuation coefficient, elinganiswa kwi-dB/km, yiparameter ephambili esetyenziselwa ukuvavanya ukulahleka kokudluliselwa. Ibangelwa ikakhulu kukufunxwa kwezinto kunye nokusasazeka kwazo. Kwi-C-band, i-attenuation ingaba phantsi malunga ne-0.2 dB/km, ngelixa iphezulu kancinci kwi-O-band.
Ifayibha ye-optical yemowudi enye ebonelelwa yi-ONE WORLD yenziwe kusetyenziswa izixhobo ezicocekileyo kakhulu kunye neenkqubo ezizinzileyo, ukuqinisekisa ukusebenza okuzinzileyo kokunciphisa ngaphakathi kwemigangatho emiselweyo yokudluliselwa okuthembekileyo komgama omde.
Iimpawu zokusasazeka:
Ukusasazeka kubhekisa kumahluko kwisantya sokusasazeka kokukhanya kwiiwavelengths ezahlukeneyo, nto leyo ekhokelela ekwandiseni isignali. Ngokwenza ngcono ukwakheka kwezinto kunye noyilo lwesakhiwo, iifayibha zinokwakhiwa ngeempawu ezahlukeneyo zokusasazeka ukuze zihlangabezane neemfuno ezahlukeneyo zonxibelelwano.
Ubude beWavelength obunqamlezileyo:
I-cut-off wavelength yeyona wavelength incinci apho uthumelo lwendlela enye lunokugcinwa khona, ngesiqhelo luphakathi kwe-1260–1300 nm. Ngaphantsi kweli xabiso, iindlela eziphezulu zinokusasazeka, zichaphazele uzinzo lwesignali. I-ONE WORLD ilawula ngokungqongqo i-cut-off wavelength ukuqinisekisa ukusebenza okuzinzileyo kwendlela enye ngaphakathi koluhlu oluchaziweyo lokusebenza.
Ububanzi beNdawo yeMode (MFD):
Ububanzi bentsimi yemowudi buchaza ukusasazwa kwentsimi ye-optical kwi-fiber core kwaye buchaphazela ukusebenza kakuhle kokudibanisa kunye nokusebenza koqhagamshelo. Iinkcukacha ezahlukeneyo ze-MFD ziyafumaneka ukuhlangabezana neemfuno ezahlukeneyo zoyilo lwenkqubo kunye nokupakisha.
4. Ukuphucula ukusebenza koThumelo
Ukusebenza kokudluliselwa kwefayibha ye-optical yemowudi enye kunokuphuculwa ngakumbi ngokuphucula ubumsulwa bezinto kunye neenkqubo zokuvelisa ezifana ne-MCVD (Modified Chemical Vapor Deposition). Olu phuculo lunceda ekunciphiseni ukufunxwa kokungcola kunye neziphene zesakhiwo, nto leyo ekhokelela ekuncipheni okuncinci kunye neempawu zokusasazeka ngcono.
I-ONE WORLD iqhubeka nokulandela uphuhliso lweshishini kwaye isebenza ngokusondeleyo namaqabane athembekileyo asezantsi ukubonelela ngeemveliso zefayibha ye-optical ezizinzileyo nezisemgangathweni ophezulu.
5. Isiphelo
Iimpawu zobude be-wavelength kunye nokudluliselwa kwe-fiber optical ye-single-mode zimisela ngokuthe ngqo ukusebenza kweenkqubo zonxibelelwano lwe-optical. Ukuqonda ngokucacileyo ezi parameters zibalulekileyo kunceda ukuphucula uyilo lwenethiwekhi ye-fiber kunye nokuhlangabezana nemfuno ekhulayo yokudluliselwa kwedatha ngesantya esiphezulu nangomthamo ophezulu.
Njengeqabane elithembekileyo kwizixhobo zekhebula, i-ONE WORLD izimisele ukubonelela ngefayibha ye-optical yemowudi enye ezinzileyo nethembekileyo ukuxhasa iiprojekthi zakho zonxibelelwano. Zive ukhululekile ukunxibelelana nathi ukuze ufumane ulwazi oluthe kratya ngemveliso kunye nenkxaso yobugcisa.
