Funda Ukuhlukaniswa Okuyinhloko Kuqala: Izici Zefomu Lokuxhumanisa le-SC vs LC

Ngaphambi kokuqhathanisa izitayela zokupholisha, udinga ukuqinisekisa usayizi ongokoqobo wesixhumi kanye nesakhiwo sokukhiya, umehluko oyinhloko ohlukanisa izixhumi ezisheshayo ze-SC kanye ne-LC ezivamile emakethe.

I-SC (Isixhumi Sokubhalisa)

Ngokuvamile eyaziwa ngokuthi isixhumi sefayibha yesikwele, imodeli ye-SC isebenzisa umklamo olula wokukhiya ocindezelayo nokudonsa odinga amakhono amancane okusebenza. Ine-ferrule enkulu ye-ceramic engu-2.5mm ngaphakathi kwegobolondo lepulasitiki, enokumelana okuqinile kwesakhiwo ekucindezelweni nasekuweni. Lesi sixhumi sivelele emsebenzini wokwakha wangaphandle nohlakazekile lapho isikhala se-rack esincane singeyona into eza kuqala. Sesibe yinto ekhethwayo kakhulu yezintambo ze-FTTH fiber drop kanye namaphrojekthi okuxhumana kwedatha ajwayelekile, ngenxa yokuqina kwayo okubonakalayo okuqhubekayo kanye nesikhathi sokuphila esiphezulu se-plug-and-play semishini. Abafaki abasha bangasebenzisa izixhumi ze-SC kahle ngaphandle kokuqeqeshwa okuyinkimbinkimbi, banciphise kakhulu amazinga amaphutha okuphela kwensimu.

I-LC (Isixhumi se-Lucent)

Isixhumi se-LC siyindlela encane ehlanganisiwe esikhundleni se-SC, efakwe isakhiwo esincane se-latch esinwebekayo esifana nama-plug e-RJ45 Ethernet. Umthamo waso uwonke cishe uhhafu wesixhumi se-SC, okuvumela ukuthi kuhlelwe ama-port amaningi kakhulu kumaphaneli e-patch anobukhulu obufanayo. Lo mklamo wenza i-LC ibe yisinqumo esiphezulu sezimo zokufakwa kwabantu abaningi, kufaka phakathi i-coreisikhungo sedathaAmakhabethe namakamelo omshini wangaphakathi ebhizinisi. Kumaphrojekthi adinga ukuxhumeka okukhulu kwezixhumanisi zefayibha ezisheshayo ze-10G, 40G kanye ne-100G, izixhumi ezisheshayo ze-LC zilinganisela ukwakheka okuqinile kanye nokudluliselwa kwesignali okuzinzile okuzinzile kahle. Nokho, ibhande layo elincane elinwebekayo alimelani kakhulu nokwakhiwa okuqinile kwangaphandle, okwenza lingafaneleki ukufakwa kwezintambo zensimu eziveziwe.

Khetha izixhumi ze-LC ezisheshayo uma wakha ama-racks e-data centre aqinile kanye nezinhlelo zokuxhuma ezihlanganisiwe zangaphakathi. Khetha izixhumi ze-SC ezisheshayo ze-LCikhebula lokudonsa le-FTTH langaphandleukwakhiwa, izintambo zamabhokisi okusabalalisa umphakathi, kanye namaphrojekthi anamaqembu amakhulu abasebenzi basensimini abangenalwazi ababeka phambili ukuqina nokusebenza okulula.

Ukupholisha Ubuso Bokugcina Kwenza Umehluko Wonke: I-UPC vs I-APC

Amaphutha amaningi okuthenga nokufaka avela ekuhlanganiseni izixhumi ze-UPC ne-APC. Ngaphandle kokuhlonza umbala okuyisisekelo (indlu eluhlaza okwesibhakabhaka ye-UPC, indlu eluhlaza ye-APC), igebe lazo eliyinhloko lisezingongeni zobuso be-ferrule end, okushintsha ngokuyisisekelo ukusebenza kokukhanya kwe-optical futhi kunqume ukuthi yiziphi izinhlelo zenethiwekhi ezifanelana nazo.

I-UPC (Ukuthintana Okuphezulu Komzimba)

Ama-ferrule e-UPC adlula ekugayweni okuhle okunezindilinga eziningi ukuze akhe ubuso obuyisicaba obuyindilinga obuthambile obunobuso obuqondile obuyi-0 degree obubheke umthombo wokukhanya. Lo mklamo uletha ukulahlekelwa okuvamile kokufakwa okungaphansi kuka-0.3dB kanye nokulahlekelwa kokubuya okusukela ku--50dB kuya ku--55dB. Izindleko zokukhiqiza zeIzixhumi ze-UPCzihlala zingabizi kakhulu, futhi indawo yazo eyisicaba kulula ukuyisula nokuyinakekela endaweni. Zifanelana nezimo eziningi zokudlulisa zedijithali ezihlanzekile, kufaka phakathi i-Ethernet yehhovisi, izixhumanisi zefayibha zokuqapha ifektri kanye nemigqa yedatha yangaphakathi emfushane. Kulezi zinhlelo, ukubonakaliswa okuncane kokubuyela emuva kwesignali kudala ukuphazamiseka okuncane kwesignali ye-laser yedijithali, ngakho-ke i-UPC ihlangabezana ngokugcwele nezidingo zokusebenza kwansuku zonke.

I-APC (Ukuthintana Okungokomzimba Okune-Angle)

Ama-ferrule e-APC anobuso obucwebezelayo obunama-degree angu-8, umklamo oyinhloko ophambukisa ukukhanya okukhanyayo kungene ekumbozweni kwefayibha esikhundleni sokubuyela emuva kusidluliseli se-laser.Izixhumi ezisheshayo ze-APCIfinyelela kalula ekulahlekelweni kokubuya okungaphezu kwe--60dB, okususa ngempumelelo ukuphambuka kwesignali okubangelwa ukubonakaliswa kwangemuva. Lokhu kusebenza okuyingqayizivele akunakuthathelwa indawo yizinhlelo ezithile zokudlulisa ukukhanya. Uma imigqa iphethe izimpawu zevidiyo ze-analog CATV noma isebenzisa imishini ye-PON ebucayi, ukukhanya okubukisiwe emuva kuzoholela ezinhlayiyeni zeqhwa zesithombe, amasignali e-ONU avamile angaxhunyiwe ku-inthanethi kanye ne-broadband engazinzile ngaphandle kwezixhumi ze-APC. Noma yimiphi imisebenzi yokudlulisa ukukhanya enamandla aphezulu ebanga elide idinga amazinga okupholisha e-APC.

Ukuxhumanisa izixhumi ze-UPC ne-APC kusixhumanisi esisodwa sefayibha akuvunyelwe ngokuphelele. Ubuso obungalingani obuyisicaba nobune-engile abukwazi ukwakha ukuxhumana okuqinile kwe-optical, okusunduza ukulahlekelwa kokufakwa kube ngaphezu kwe-1dB futhi kukhubaze ukudluliswa kwesignali okuvamile. Sebenzisa izixhumi ze-UPC ezisheshayo zezixhumanisi ezijwayelekile ze-Ethernet yedijithali ukulawula izindleko; izixhumi ze-APC ezisheshayo ziyimpoqo kumanethiwekhi e-CATV, PON angasebenzi kanye nemishini yokudlulisa i-optical enembayo ephezulu.
