I-UPC yodidi lwe-fiber optic isidibanisi luhlobo oluqhelekileyo lokudibanisa kwintsimi yonxibelelwano lwefiber optic, eli nqaku liza kuhlalutya malunga neempawu zalo kunye nokusetyenziswa.
UPC uhlobo lwefiber optic iimpawu zesihlanganisi
1. Ubume besiphelo sobuso be-UPC isikhonkwane se-pin isiphelo siphuculwe ukwenza ubuso baso bugudiswe ngakumbi, bumile okwedome. Olu luyilo luvumela ubuso bokuphela kwefiber optic ukuba bufezekise unxibelelwano olusondeleyo xa kusenziwa i-docking, ngaloo ndlela kuncitshiswe impembelelo yokubonakalisa iFresnel.
2. Ilahleko ephezulu yokubuyisela xa kuthelekiswa nohlobo lwePC, i-UPC inikezela ngelahleko ephezulu yokubuya, ngokuqhelekileyo inokufikelela ngaphezu kwe-50dB, oku kuthetha ukuba inokunciphisa kangcono impembelelo yokukhanya okungafunekiyo okubonakalayo kwindlela yokusebenza kwenkqubo.
3. Ilahleko yokufaka ephantsi Ngenxa yenkqubo yokuvelisa ngokuchanekileyo kunye nobuchwepheshe be-polish high-quality, izixhumi ze-UPC zihlala zikwazi ukuphumeza ukulahlekelwa okuphantsi kokufakwa, ngokuqhelekileyo ngaphantsi kwe-0.3dB, enceda ukugcina amandla omqondiso kunye nokunyaniseka.
Iimeko zodidi lwe-UPC izihlanganisi zefiber optic
Ngokubhekiselele kwezi mpawu zingentla, izixhumi ze-UPC zifanelekile kwiimeko ezahlukeneyo zesicelo, ezifana nezixhobo zenethiwekhi ye-Ethernet, i-ODF (i-Optical Distribution Frame) iifreyimu zokusabalalisa i-fiber optic, abaguquli beendaba kunye nokutshintshwa kwe-fiber optic, njl., ezihlala zifuna ukuhanjiswa kwesignali ezinzileyo kunye nekhwalithi ephezulu. Kukho kwakhona i-TV yedijithali kunye neenkqubo zomnxeba, ezineemfuno eziphezulu zomgangatho wesignali, kunye nexabiso eliphezulu lokulahlekelwa kwembuyekezo yezixhumi ze-UPC kunceda ukuqinisekisa ukuchaneka kunye nokuzinza kokuhanjiswa kwedatha.
Ikwabandakanya izicelo ezifuna umgangatho ophezulu wesignali. Kwizicelo ze-carrier-grade, ezifana ne-data-transmission links ngaphakathi kwamaziko edatha okanye imigca ye-backbone kwi-network-class network networks, izixhumi ze-UPC zisetyenziswa ngokubanzi ngenxa yokusebenza kwazo okuphezulu. Nangona kunjalo, kwiimeko ezithile, ezifana neenkqubo zonxibelelwano ze-analog optical ezifana ne-CATV okanye iinkqubo ze-WDM zisebenzisa i-Raman fiber amplifiers, apho umgangatho ophezulu wokubuyisela ukulahlekelwa kwelahleko unokufuneka, ikhonkco ye-APC inokukhethwa ngaphezu kwe-UPC.Oku kungenxa yokuba nangona ii-UPCs sele zibonelela ngokusebenza kakuhle kwelahleko yokubuyisela, phantsi kweemeko ezinzima, ezifana nobukho bokungcola okunzima kwe-endface, inzuzo eyongezelelweyo yokubuyisela iba yilahleko eyongezelelweyo.
