Isixhumi se-fiber optic sohlobo lwe-UPC luhlobo oluqhelekileyo lwesixhumi kwicandelo lonxibelelwano lwe-fiber optic, eli nqaku liza kuhlalutya malunga neempawu zaso kunye nokusetyenziswa kwaso.
Iimpawu zesixhumi se-fiber optic yohlobo lwe-UPC
1. Imilo yobuso bokugqibela ubuso be-UPC connector pin end ilungiselelwe ukwenza umphezulu wayo ube bushelelezi, umile okwedome. Olu yilo luvumela ubuso be-fiber optic ukuba bufikelele ekudibaneni kufutshane xa kudokwa, ngaloo ndlela kunciphisa impembelelo yokubonakaliswa kweFresnel.
2. Ilahleko ephezulu xa ithelekiswa nohlobo lwePC, i-UPC ibonelela ngelahleko ephezulu yokubuyisela, idla ngokufikelela ngaphezulu kwe-50dB, oko kuthetha ukuba inokuyicinezela ngcono impembelelo yokukhanya okungafunekiyo okubonakalayo ekusebenzeni kwenkqubo.
3. Ukulahleka okuphantsi kokufakwa Ngenxa yenkqubo yayo yokuvelisa ngokuchanekileyo kunye netekhnoloji yokupholisha ekumgangatho ophezulu, izihlanganisi ze-UPC zihlala zikwazi ukufumana ukulahleka okuphantsi kokufakwa, ngokubanzi zingaphantsi kwe-0.3dB, nto leyo enceda ukugcina amandla esignali kunye nokuthembeka.
Imeko zezihlanganisi ze-fiber optic ze-UPC
Ngenxa yeempawu ezingasentla, izihlanganisi ze-UPC zifanelekile kwiimeko ezahlukeneyo zokusetyenziswa, ezifana nezixhobo zenethiwekhi ye-Ethernet, iifreyimu zokusasazwa kwe-fiber optic ze-ODF (Optical Distribution Frame), ii-media converters kunye neeswitshi ze-fiber optic, njl.njl., ezidla ngokufuna ukuhanjiswa kwesignali ye-optical okuzinzileyo nokusemgangathweni ophezulu. Kukwakho neenkqubo zeTV zedijithali kunye neefowuni, ezineemfuno eziphezulu zomgangatho wesignali, kwaye ixabiso eliphezulu lokulahleka kwembuyekezo yezihlanganisi ze-UPC linceda ukuqinisekisa ukuchaneka kunye nokuzinza kokudluliselwa kwedatha.
Ikwabandakanya usetyenziso olufuna umgangatho ophezulu wesignali. Kwizicelo zenqanaba lokuthwala, ezifana neekhonkco zokudlulisa idatha ngaphakathi kwamaziko edatha okanye imigca yomqolo kwiinethiwekhi zeklasi yeshishini, izihlanganisi ze-UPC zisetyenziswa kakhulu ngenxa yokusebenza kwazo okuphezulu. Nangona kunjalo, kwiimeko ezithile, ezifana neenkqubo zonxibelelwano lwe-analog optical ezifana neenkqubo ze-CATV okanye ze-WDM ezisebenzisa ii-amplifiers zefayibha yeRaman, apho inqanaba eliphezulu lolawulo lokulahleka kokubuya linokufuneka, isihlanganisi se-APC sinokukhethwa kune-UPC. Oku kungenxa yokuba nangona ii-UPC sele zibonelela ngokusebenza okuhle kakhulu kokulahleka kokubuya, phantsi kweemeko ezinzima, ezifana nokubakho kongcoliseko olukhulu lwe-endface, inzuzo eyongezelelweyo yokulahleka kokubuya iba yinto ebaluleke kakhulu.
