Txheej txheem cej luam ntawm SC, LC, ST, FC Connectors
Taw qhia
Muaj ntau qhov chaw nres nkoj fiber ntau siv hauv kev sib txuas lus fiber ntau. Tej zaum SC, LC, ST thiab FC yog hom fiber ntau txuas uas koj yuav ntsib hauv lub neej txhua hnub. Lawv nquag siv hauv kev sib txuas lus hauv xov tooj niaj hnub no. Txawm hais tias lawv muaj qee qhov zoo sib xws, txhua yam sib txawv ntawm lwm tus hauv qhov loj thiab cov duab los tiv thaiv lawv los ntawm kev siv sib hloov. Thaum npaj cov khoom siv fiber ntau rau kev teeb tsa, nws yog ib qho tseem ceeb los xyuas kom meej tias cov cables sib phim nrog cov khoom sib txuas tsim nyog.
SC
SC stands rau "Subscriber Connector," tseem hu ua "Square Connector." Nws yog arguably hom fiber ntau optic connector siv niaj hnub no. Lub SC nta lub snap-in push / rub coupling mechanism nrog 2.5mm ferrule, uas yog tsim los ntawm JP NTT nyob rau hauv nruab nrab ntawm 1980s. Nws tau txais koob meej thiab tau siv dav hauv ib hom fiber ntau optic cable, xws li telecom thiab datacom.
LC
LC yog lub npe luv rau Lucent Connector, muaj npe tom qab nws tus tsim Lucent Technologies. LC nta lub laub / rub txuas txuas nrog lub latch. Nws yog feem ntau hu ua "tus txuas me me" vim tias nws yog ib tus tswv cuab me me (SFF). Lub ntsiab muag ntawm LC yog nws 1.25 hli ferrule, uas yog ib nrab ntawm cov ferrule ntawm SC, ST thiab FC thiab muaj ib tug me me tag nrho hneev taw. Vim li no, LC feem ntau siv nyob rau hauv high-density chaw. SC thiab LC yog tam sim no nyob rau hauv ib tug khi, nrog LC tej zaum yuav tawm los nyob rau hauv lub sij hawm ntev.
ST
ST hais txog "Straight Tip", uas yog xyoo 1980s invention los ntawm AT&T uas siv ib nrab twist bayonet mount nqa ib tug ntev, cylindrical 2.5mm caij nplooj ntoos hlav loaded ferrule. Nws tau nquag siv hauv tsev kawm qib siab, kev lag luam thiab tub rog ntau hom tes hauj lwm vim nws pheej yig thiab yooj yim rau ntsaws thiab tshem tawm. Txog rau xyoo 2005, nws yog qhov siv ntau tshaj plaws txuas rau ntau hom kev tes hauj lwm. Txawm li cas los xij, nws txoj kev siv tau nruj heev vim nws tsis sib haum nrog APC.
FC
FC sawv cev rau "ferrule connector" lossis "fibre channel," tsim los ntawm JP NTT. Nws yog ib puag ncig threaded connector uas yog siv rau hauv datacom, telecommunications, ntsuas khoom, thiab ib hom lasers. Nws muaj 2.5 hli ferrule nyob ib puag ncig lub tsev stainless-steel. Piv nrog rau cov khoom siv fiber ntau optic tshiab, FC siv sijhawm ntev dua rau kev tshem tawm vim lawv cov threaded screw-on siv. Nws kuj tseem kim dua los tsim FC vim muaj kev sib txuam tsim thiab siv hlau. Tam sim no FC tau maj mam dhau los lawm.
