Cov Lus Qhia Yooj Yim ntawm Fiber Txuas
Fiber txuas yog siv los txuas cov fiber ntau qhov txuas qhov txuas / disconnect lub peev xwm yog yuav tsum tau. Cov kab hluav taws xob tshem tawm kev sib txuas fiber ntau rau cov khoom siv fiber ntau lossis koom nrog ob qho kev sib txuas fiber ntau tsis muaj splicing. Fiber Optic Connector yog ib qho tseem ceeb uas siv rau hauv cov koom haum hauv fiber ntau. Nws tseem yog qhov tseem ceeb siv hauv miv 7 cable thiab fiber ntau optic pigtail. Cov xaim hluav taws xob txuas tau hloov tau yooj yim, poob qis, tus nqi qis dua, yooj yim rau kev txiav tawm lossis daws qee qhov teeb meem pom tau.
Chav tsev txuas theem pib yog qhov sib dhos ntawm cov khoom sib txuas. Cov khoom siv tseem ceeb muaj xws li lub cev tsis muaj zog, lub cev sib sau ua ke, cable, kev nyuaj siab nyem khau thiab cov vaj tsev txuas. Cov txuas txuas tam sim no feem ntau siv “kev sib cuag lub cev” cov xim nyob rau ntawm fiber thiab ferrule kawg. Qhov no yog ib nyuag nkhaus nto, thiaj li hais tias thaum cov fibers tau mated tsuas yog cov fiber cores kov, tsis yog cov nyob ze ferrules. Cov kab hluav taws xob-rau-fiber sib txuas ua ke muaj kev sib cais, kev sib txuas mus tas li, lossis cov txuas, uas sib txawv ntawm qhov sib cais hauv nws lub peev xwm ua kom muaj kev cuam tshuam thiab txuas nrog.
Txhua qhov kev sib txuas fiber ntau muaj ob qhov tseem ceeb:
Attenuation los yog tso ntxig poob;
Kev xav txog lossis rov qab poob.
Cov khoom siv kho qhov muag fiber ntau tau qhia nrog cov khoom siv fiber ntau hauv 1980s. Fiber optic txuas hom muaj ntau yam xws li daim ntawv thov rau qhov lawv tau tsim. Hom sib txuas sib txawv muaj cov yam ntxwv sib txawv, qhov zoo sib txawv thiab qhov tsis zoo, thiab qhov sib txawv ntawm kev ua haujlwm. Cov khoom sib txuas raug ntsuas rau ntawm 500-1,000 mating ncig. Lub ntsiab sib txawv ntawm cov hom sib txuas yog qhov ntev thiab cov qauv ntawm kev sib txuas ntawm lub tshuab. Feem ntau, cov koomhaum yuav ua tus qauv rau ntawm ib hom kev txuas, nyob ntawm seb cov khoom siv twg lawv ib txwm siv. Cov khoom sib txuas sib txawv yog qhov xav tau rau multimode, thiab rau ib hom fiber ntau. Pua pua ntawm cov khoom siv kho qhov muag fiber ntau tau muaj, tab sis tsuas yog qee tus sawv cev feem ntau ntawm cov lag luam. Cov khoom siv dav siv hluav taws xob txuas nrog SC txuas, LC txuas, FC txuas, ST txuas, FDDI txuas thiab E2000 txuas.
LC connectors qee zaum hu ua "Cov Khoom Txuas Me Me".
Cov khoom sib txuas MT-RJ zoo li cov xov me me 8P8C txuas - feem ntau (tab sis yuam kev) hu ua RJ-45.
Cov khoom sib txuas ST hais txog qhov muaj "ncaj ncaj", raws li ob tog ntawm cov ceramic (uas muaj qhov kub qis dua qhov ua kom sib npaug ntawm cov hlau) cov taub yog cov sib npaug - tsis zoo rau cov thawj ntawm ob qho kev sib txuas uas sib txuas li ob lub zes khov nab kuab. yuav. Lwm qhov kev sau ntawv suav nrog suav “Teeb thiab Twist”, “Stab and Twist”, thiab “Ib Leeg”, hais txog qhov nws ntxig li cas (txoj xov raug thawb rau hauv lub txais, thiab lub thawv sab nraud yog sib ntswg los xauv nws mus rau hauv qhov chaw). Tsis tas li lawv tau lub npe hu ua "Square Top" vim yog lub ntsej muag kawg.
SC cov khoom sib txuas, yog lub xwmfab, muaj mnemonic ntawm "Square Connector", uas qee cov neeg ntseeg tias yog lub npe raug, dua li cov nom tshaj "Cov Neeg Txuas Siv". Lwm cov lus siv feem ntau siv rau SC cov txuas yog "Teeb thiab Nyem" lossis "Stab thiab Nyem".
Cov yam ntxwv ntawm kev sib txuas zoo tsim:
Tsawg poob zoo;
Siab rov qab poob (qhov tsis tshua muaj siab xav txog ntawm qhov cuam tshuam);
Yooj yim ntawm installation;
Tus nqi qis;
Kev ntseeg tau;
Tsis tshua muaj kev tiv thaiv ib puag ncig;
Yooj yim ntawm kev siv.
