Izixhumi ezibonakalayo zisetshenziselwa ukuxhumana phakathi kwamadivaysi enethiwekhi ezikhungweni zedatha kanye nasekuxhumekeni kweikhebula le-fiber optickumishini emagcekeni ekhasimende (isb. FTTH).Phakathi kwezinhlobo ezahlukene ze-fiber connector, i-SC ne-LC yizixhumi ezimbili ezivame ukusetshenziswa kakhulu.I-SC vs LC: uyini umehluko futhi iyiphi engcono?Uma ungakabi nayo impendulo.Ungathola umkhondo lapha.
Iyini i-SC Connector?
Ithuthukiswe amalabhorethri e-Nippon Telegraph and Telephone (NTT) maphakathi nawo-80, isixhumi se-SC sasingesinye sezixhumi zokuqala ezifika emakethe kulandela ukuvela kwezithako ze-ceramic.Kwesinye isikhathi okubizwa ngokuthi "isixhumi esiyisikwele" i-SC inobuso obuhlangene bokusunduza obunomshini we-ceramic olayishwe intwasahlobo.Ekuqaleni yayihloselwe inethiwekhi ye-Gigabit Ethernet, yafakwa ku-TIA-568-A yezokuxhumana ngo-1991 futhi yakhula kancane ekudumeni njengoba izindleko zokukhiqiza zehla.Ngenxa yokusebenza kwayo okuhle kakhulu ibibusa i-fiber optics isikhathi esingaphezu kweshumi leminyaka i-ST kuphela eqhudelana nayo.Eminyakeni engamashumi amathathu kuqhubeke, ihlala iyisixhumi sesibili esivame kakhulu sokugcinwa kwe-polarization egcina izinhlelo zokusebenza.I-SC ifaneleka kahle kuma-datacoms kanye nezinhlelo zokusebenza zezingcingo ezihlanganisa iphuzu nephoyinti kanye nenethiwekhi ye-passive optical networking.
Iyini i-LC Connector?
Abanye kucatshangelwa njengokushintshwa kwesimanje kwesixhumi se-SC, ukwethulwa kwesixhumi se-LC akuphumelelanga kangako, ngokwengxenye ngenxa yezinkokhelo zamalayisense eziphakeme ekuqaleni ezivela kumsunguli we-Lucent Corporation.Njengesixhumi se-push-pull futhi, i-LC isebenzisa i-latch ngokuphambene nethebhu yokukhiya ye-SC futhi nge-ferrule encane yaziwa njengesixhumi se-factor factor encane.Ukuba nohhafu wonyawo lwesixhumi se-SC kuyenza idume kakhulu kuma-datacoms nakwezinye izinhlelo zokusebenza zepheshi eziminyana kakhulu, njengoba inhlanganisela yayo yosayizi omncane kanye nesici se-latch iyenza ilungele ama-rack/amaphaneli anabantu abaningi.Ngokwethulwa kwama-transceiver ahambisanayo e-LC kanye nezingxenye zokuxhumana ezisebenzayo, ukukhula kwayo okuqhubekayo enkundleni ye-FTTH cishe kuzoqhubeka.
I-SC vs LC: Ihluke Kanjani Kokunye
Ngemuva kokuba nokuqonda okuyisisekelo kwakho kokubili isixhumi se-SC ne-LC, ungase ubuze ukuthi yini umehluko futhi asho ukuthini ekusebenziseni kwakho?Ithebula elingezansi linikeza umbono wamandla nobuthakathaka.Futhi ngokujwayelekile, umehluko phakathi kwe-LC ne-SC fibre optic connector ilele kusayizi, ukuphatha kanye nomlando wokuxhuma, okuzoxoxwa ngakho ngokulandelana embhalweni olandelayo.
- Usayizi: I-LC iyingxenye kasayizi we-SC.Empeleni, i-adaptha ye-SC eyodwa ilingana ncamashi ne-adaptha ye-LC eyi-duplex.Ngakho-ke i-LC ivame kakhulu emahhovisi amaphakathi lapho ukuminyana kokupakisha (inombolo yokuxhuma endaweni ngayinye) kuyisici esibalulekile sezindleko.
- Ukubamba: I-SC iyisixhumi sangempela “sokusunduza-sidonse” futhi i-LC “iyisixhumi esixhunyiwe”, nakuba kukhona ama-“push-pull-LC” angempela atholakalayo anamandla okubamba afanayo njenge-SC.
- Umlando Wesixhumi: I-LC iyisixhumi "esincane" sababili, i-SC isakazeke kabanzi emhlabeni wonke kodwa i-LC ibamba iqhaza.Zombili izixhumi zinokulahlekelwa okufanayo kokufakwa namandla okulahlekelwa kokubuyisela.Ngokuvamile, kuya ngokuthi kunethiwekhi ufuna ukusebenzisa kuphi isixhumi, kungakhathaliseki ukuthi i-SC noma i-LC, ngisho nezinye izinhlobo ezihlukene zesixhumi.
Isifinyezo
Ubuchwepheshe bezokuxhumana bamanje nobuzayo bufuna ukusebenza ngokushesha, okuphumelelayo nokuphephile enqubweni yokuxhumana kwedatha.Imininingo egciniwe emikhulu neyinkimbinkimbi yonke into exhumene kufanele ikwazi ukwamukela nokudlulisa idatha ngaphandle kokuphazamiseka kwangaphandle.Kokubili i-SC ne-LC yakhelwe ukufeza uhlobo olunjalo lokudlulisela.Ngokuqondene nombuzo othi “SC vs LC: uyini umehluko futhi iyiphi engcono?”, udinga nje ukugcina amaphuzu amathathu ayisisekelo engqondweni: 1. I-SC inezindlu zokuxhuma ezinkulu kanye ne-ferrule engu-2.5mm enkulu.2. I-LC inendlu yokuxhuma encane kanye ne-ferrule encane engu-1.25mm.3. I-SC yayivame ukufutheka, kodwa manje i-LC.Ungakwazi ukufaka ukuxhumana okwengeziwe emakhadini olayini, amaphaneli, njll ngesixhumi se-LC.
