Isixhumi se-fiber optic sohlobo lwe-UPC siwuhlobo lwesixhumi esivamile emkhakheni wokuxhumana kwe-fiber optic, lesi sihloko sizohlaziya izici zaso kanye nokusetshenziswa kwaso.
Izici zesixhumi se-fiber optic sohlobo lwe-UPC
1. Ukuma kobuso bokugcina ubuso bephini yokuxhuma ye-UPC kulungiselelwe ukwenza ubuso bayo bube bushelelezi, bube njengedome. Lo mklamo uvumela ubuso bokugcina be-fiber optic ukuthi bufinyelele ukuxhumana okuseduze lapho kudokwa, ngaleyo ndlela kuncishiswe umthelela wokubonakaliswa kwe-Fresnel.
2. Ukulahlekelwa okuphezulu kokubuyiselwa uma kuqhathaniswa nohlobo lwe-PC, i-UPC inikeza ukulahlekelwa okuphezulu kokubuyiselwa, ngokuvamile ingafinyelela ngaphezu kwama-50dB, okusho ukuthi ingacindezela kangcono umthelela wokukhanya okukhanyayo okungafuneki ekusebenzeni kwesistimu.
3. Ukulahlekelwa okuncane kokufakwa Ngenxa yenqubo yayo yokukhiqiza ngokunemba kanye nobuchwepheshe bokupholisha obusezingeni eliphezulu, izixhumi ze-UPC zivame ukukwazi ukufeza ukulahlekelwa okuncane kokufakwa, ngokuvamile okungaphansi kuka-0.3dB, okusiza ukugcina amandla esignali kanye nobuqotho.
Izimo zezixhumi ze-fiber optic zohlobo lwe-UPC
Ngenxa yezici ezingenhla, izixhumi ze-UPC zifanelekela izimo ezahlukahlukene zohlelo lokusebenza, njengemishini yenethiwekhi ye-Ethernet, ozimele bokusabalalisa be-fiber optic be-ODF (Optical Distribution Frame), abaguquli bemidiya kanye nezishintshi ze-fiber optic, njll., ezivame ukudinga ukudluliswa kwesignali ye-optical okuzinzile nokuseqophelweni eliphezulu. Kukhona nezinhlelo ze-TV zedijithali kanye nezingcingo, ezinezidingo eziphezulu zekhwalithi yesignali, kanye nenani lokulahlekelwa okuphezulu kwezixhumi ze-UPC kusiza ukuqinisekisa ukunemba nokuzinza kokudluliswa kwedatha.
Iphinde ifake izinhlelo zokusebenza ezidinga ikhwalithi ephezulu yesignali. Ezinhlelweni zokusebenza zezinga lenkampani, njengezixhumanisi zokudlulisa idatha ngaphakathi kwezikhungo zedatha noma imigqa yomgogodla kumanethiwekhi ekilasi lebhizinisi, izixhumi ze-UPC zisetshenziswa kabanzi ngenxa yokusebenza kwazo okuphezulu. Kodwa-ke, ezimweni ezithile, njengezinhlelo zokuxhumana ze-analog optical njengezinhlelo ze-CATV noma ze-WDM ezisebenzisa ama-amplifiers e-Raman fiber, lapho kungadingeka khona izinga eliphezulu lokulawula ukulahlekelwa kokubuya, isixhumi se-APC singakhethwa kune-UPC. Lokhu kungenxa yokuthi yize ama-UPC esevele enikeza ukusebenza okuhle kakhulu kokulahlekelwa kokubuya, ngaphansi kwezimo ezimbi kakhulu, njengokuba khona kokungcola okukhulu kokuphela, inzuzo eyengeziwe yokulahlekelwa kokubuya iba yinto ebaluleke kakhulu.
