Izihlanganisi ze-Optical zisetyenziselwa uqhagamshelwano phakathi kwezixhobo zenethiwekhi kumaziko edatha kunye noqhagamshelwano lweintambo yefiber optickwizixhobo ezikwindawo yabathengi (umz. FTTH).Phakathi kweentlobo ngeentlobo ze-fiber connector, i-SC kunye ne-LC zimbini zezona zixhamli zisetyenziswayo.I-SC vs LC: yintoni umahluko kwaye yeyiphi engcono?Ukuba awukafumani mpendulo okwangoku.Ungafumana umkhondo apha.
Yintoni i-SC Connector?
Iphuhliswe ziilabhoratri zaseNippon Telegraph kunye neTelefoni (NTT) phakathi kwiminyaka yamashumi asibhozo, isinxibelelanisi seSC saba sesinye seziqhagamshelo zokuqala ukubetha imakethi emva kokufika kweeferrules zeceramic.Ngamanye amaxesha kubhekiselwa kuyo njenge "square connector" i-SC inobuso bokudibanisa ukutyhala kunye nentwasahlobo elayishwe i-ceramic ferrule.Ekuqaleni yenzelwe uthungelwano lwe-Gigabit Ethernet, yabekwa emgangathweni kwiinkcukacha zonxibelelwano lwe-TIA-568-A ngo-1991 kwaye yakhula ngokucothayo ekudumeni njengoko iindleko zokuvelisa zazisehla.Ngenxa yokusebenza kwayo okugqwesileyo ibilawula i-fiber optics ngaphezulu kweshumi leminyaka kuphela i-ST ekhuphisana nayo.Iminyaka engamashumi amathathu ukuya phambili, ihlala iseyesibini isiqhagamshelo esixhaphakileyo kwipolarization yokugcina izicelo.I-SC ifaneleke ngokufanelekileyo kwii-datacoms kunye nezicelo ze-telecoms ezibandakanya indawo ukuya kwindawo kunye ne-passive optical networking.
Yintoni iLC Connector?
Ithathwa ngabanye njengotshintsho lwangoku lwesinxibelelanisi se-SC, ukwaziswa kwesinxibelelanisi se-LC akuzange kube yimpumelelo kangako, ngokuyinxenye ngenxa yemirhumo yelayisensi ephezulu yokuqala evela kumqambi uLucent Corporation.Njengomdibaniso wokutyhala kwakhona, i-LC isebenzisa i-latch ngokuchasene ne-SC yokutshixa ithebhu kwaye nge-ferrule encinci yaziwa ngokuba yifom encinci yokudibanisa.Ukuba nesiqingatha sonyawo lwesiqhagamshelo se-SC kusinika ukuthandwa okukhulu kwii-datacoms kunye nezinye izicelo ezixineneyo eziphezulu, njengoko indibaniselwano yayo yobukhulu obuncinci kunye ne-latch feature iyenza ilungele iirack/iipaneli ezixineneyo.Ngokungeniswa kwee-transceivers ezihambelanayo ze-LC kunye namacandelo enethiwekhi asebenzayo, ukukhula kwayo okuzinzileyo kwibala le-FTTH kunokwenzeka ukuba kuqhubeke.
I-SC vs LC: Bahluke njani omnye komnye
Emva kokuba nokuqonda okusisiseko kokubini kwe-SC kunye ne-LC isinxibelelanisi, unokubuza ukuba zeziphi iiyantlukwano kwaye zithetha ukuthini ekuphunyezweni kwakho?Le theyibhile ingezantsi inika isishwankathelo samandla kunye nobuthathaka.Kwaye ngokuthetha ngokubanzi, umahluko phakathi kwe-LC kunye ne-SC fibre optic connector ilele kubungakanani, ukuphathwa kunye nembali yokudibanisa, eya kuxoxwa ngokulandelelanayo kwisicatshulwa esilandelayo.
- Ubungakanani: I-LC isiqingatha sobukhulu be-SC.Ngokwenyani, enye i-adaptha ye-SC ilingana ngqo ne-duplex LC-adaptha.Ke ngoko i-LC ixhaphake ngakumbi kwiiofisi ezisembindini apho uxinaniso lokupakisha (inani loqhagamshelo kwindawo nganye) luyinto ebalulekileyo yeendleko.
- Ukuphatha: I-SC yinyani "i-push-pull-connector" kwaye i-LC "isinxibelelanisi esibambekayo", nangona kukho izinto ezintsha, zokwenyani "zokutyhala-tsala-i-LCs" ezikhoyo ezinesakhono sokuphatha esifanayo njenge-SC.
- Imbali ye-Connector: I-LC "yincinci" idibansi ezimbini, i-SC isasazeke ngokubanzi kwihlabathi jikelele kodwa i-LC ibamba.Zombini izihlanganisi zinelahleko efanayo yokufaka kunye nelahleko yokubuyisela amandla.Ngokubanzi, kuxhomekeke apho kuthungelwano ufuna ukusebenzisa isinxibelelanisi, nokuba i-SC okanye i-LC, nditsho nezinye iintlobo ezahlukeneyo zesinxibelelanisi.
Isishwankathelo
Itekhnoloji yonxibelelwano yangoku neyexesha elizayo ifuna ukusebenza ngokukhawuleza, ngokufanelekileyo nangokukhuselekileyo kwinkqubo yonxibelelwano lwedatha.Ugcino-lwazi olukhulu noluntsonkothileyo zonke eziqhagamshelweyo kufuneka zikwazi ukufumana nokuhambisa idatha ngaphandle kokuphazamiseka kwangaphandle.Zombini i-SC kunye ne-LC zenzelwe ukufezekisa uhlobo olunjalo losulelo.Ngokubhekiselele kumbuzo othi "SC vs LC: yintoni umehluko kwaye yiyiphi enye engcono?", Kufuneka ugcine amanqaku amathathu asisiseko engqondweni: 1. I-SC inendlu enkulu yokudibanisa kunye ne-2.5mm ferrule enkulu.2. I-LC inendlu yokudibanisa encinci kunye ne-ferrule encinci ye-1.25mm.3. I-SC yayiyiyo yonke ingqumbo, kodwa ngoku yi-LC.Unokudibanisa ngakumbi ujongano kumakhadi emigca, iiphaneli, njl.njl ngesiqhagamshelo seLC.
