Fiber Optic Termination Txheej txheem cej luam
Nws paub tias kev siv tshuaj fiber optic rho tawm sib txawv raws li cov hom fiber ntau optic cable raug kaw, tus qauv ntawm cov khoom txuas los yog kev faib tawm thiab kev txiav tawm rau qhov kev txuas ntawd. Feem ntau hais lus, fiber optic cable yuav raug kaw nyob rau hauv ob txoj kev sib txuas uas ob khub niam txiv tsim los ua ib lub sijhawm sib txuas thiab / los yog txuas tau cov fibre rau cov khoom siv network, thiab splices uas tsim ib qho chaw sib txuas ntawm ob lub fibers. Txhua txoj kev txiav tawm yuav tsum muaj ob txoj kev coj tus yam ntxwv: qhov zoo tshaj qhov kev ua tau zoo (kev poob qis thiab qhov sib txawv tsawg) thiab kev kho siab muaj zog. Raws li xws li, qhov kev txiavtxim siab ua tau rau hauv txoj cai style, ntsia ib lub sijhawm uas tsis muaj lub teeb pom kev thiab qaum rov qab thiab tiv thaiv kev tiv thaiv ib puag ncig, av lossis kev puas tsuaj thaum siv. Cov lus no tsuas yog hais txog thawj txoj kev: connector.
Feem ntau cov fiber ntau optic connectors yog cov ntaub ntawv los yog cov txiv neej sib txuas nrog cov protruding ferrule uas tuav cov fibers thiab nws txhais tau ob daim txiag rau mating. Xaiv ib lub hom sib txuas rau txhua qhov kev sib txuas yuav tsum xav txog yog tias qhov sib txuas tau sib txuas nrog lub tshuab npaj los siv cov fiber ntau optic cable cog, yog tias qhov kev txiav tawm yog paub txog lub tshuab nruab nrab thiab yog hais tias qhov sib txuas tau rau tus neeg muas zaub. Yog tias lub tshuab tseem tsis tau teev, cov hlua khi nrog ntau lub sib txuas ntawm txhua qhov kawg (xws li LC ST plug cable) tej zaum yuav tsim nyog.
Fiber optic connectors yog tsim hauv ntau hom (hais, ST, SC, LC, MT-RJ) uas xa mus rau cov fibers hauv fiber ntau optic cable (LC rau LC fiber cable ib hom) los ntawm ntau txoj hau kev, xws li epoxy polish , prepolished / splice, thiab lwm yam. ST yog ib lub connectors nrov tshaj plaws rau tes hauj lwm multimode, zoo li feem ntau cov tuam tsev thiab tsev kawm ntawv. SC yog snap-in connector uas yog dav siv hauv lub tshuab singlemode rau nws kev ua tau zoo heev thiab tshuab multimode vim nws yog tus thawj connector xaiv ua tus qauv txuas rau TIA-568. LC siv ib lub hli 1.25 hli ferrule, ib nrab ntawm qhov loj ntawm lub ST. Txwv tsis pub, nws yog ib qho kev sib txuas ntawm cov qauv siv fais fab, txuas tau yooj yim nrog cov nplaum. MT-RJ yog ib tug duplex connector nrog ob lub fibers nyob rau hauv ib qho polymer ferrule. Nws siv pins rau cov ntawv sib luag thiab muaj cov txiv neej thiab poj niam versions, yeej tsis niaj hnub no.
Muaj ntau txoj kev txiav tawm rau cov kab mob fiber ntau, thiab cov ntawv hauv qab no sau peb lub caij nyoog tso tawm: kev tshem tawm, crimp / polish txiav thiab tshem tawm ua ntej.
Adhesive Termination
Epoxy Polish: Lub fiber ntau yog glued rau hauv lub connector nrog ob tog epoxy thiab kawg polished nrog cov yeeb yam tshwj xeeb polishing. Txoj kev no muab kev txhim khu feem kev ruaj ntseg thiab qis tshaj qhov poob qis. Tus epoxy tuaj yeem tso cai kom teem caij los yog kho rau hauv qhov cub tshwj xeeb. Lub "tshav kub phom" yuav tsum tsis txhob siv los kho cov tshuaj epoxy raws li cov hluav taws kub tsis sib txig yuav kho tsis tau tag nrho cov epoxy los sis yuav ua rau nws tsis zoo uas yuav tiv thaiv kev kho.
Kub Melt: Qhov sib txuas no zoo ib yam li qhov sib txuas rau epoxy / polish, tab sis twb muaj cov nplaum (lub teeb tso kua nplaum) hauv lub connector. Lub nplaum yog liquefied nyob rau hauv ib qhov cub ua ntej lub fiber yuav tau tso. Lub fiber yog khi thaum lub nplaum txias.
Anaerobic Adhesives: Cov kev sib txuas no siv qhov ceev-nplaum es tsis txhob siv cov epoxy. Tej zaum lawv yuav siv ib qho nplaum nplaum lossis ib tus neeg sawv cev thiab cov neeg sawv cev. Ib co adhesives tsis muaj cua kub ntau ntawm epoxies, yog li lawv yuav tsum tsuas yog siv sab hauv tsev ntshe yog hais tseg.
Crimp / Polish Termination
Cov connectors siv lub crimp nyob rau hauv fiber los tuav nws nyob rau hauv lub connector ferrule. Lub fiber ntau yuav ci tau zoo ib yam li cov nplaum lossis lub nplaum nrog lub cuab tam tshwj xeeb. Txhaum tus crimp raug ua kom zoo kom tiv thaiv kom txhob muaj fiber ntau pistoning (rub rov qab los yog thawb rau hauv lub fittings connector.)
Prepolished Termination
Cov connectors muaj ib tug tw stub ntawm fiber ntau twb epoxied rau hauv ferrule thiab polished. Termination yuav tsum tau muab cais ua kom muaj fiber ntau ntxiv, muab nws tso rau hauv qab ntawm qhov sib txuas xws li ib qho thaiv thiab crimping. Qhov poob ntawm cov connectors yuav qis dua cov nplaum sib txuas, txij li thaum lawv muaj qhov poob txaij ntxiv nrog ib qho kev poob ntawm qhov poob hauv txhua txhua tus connector.
Txhawm rau kom tsis tshua poob, cov fiber ntau yuav tsum muab sib txuas kom zoo, uas yuav tsum tau muaj lub cwj pwm zoo thiab cov txheej txheem zoo. Insure lub crimp yog ua kom zoo kom tiv thaiv fiber ntau pistoning. Txoj kev tshem tawm yuav raug saib xyuas nrog lub qhov muag pom qhov teeb meem.
Connectors yuav ntsia tau ncaj qha rau feem ntau hom kabmob, nrog rau kev kaw ntom nti xws li cov ntxhuav yooj yim xws li simplex, zipcord thiab breakout cables, qhov chaw uas cov neeg muaj fiber ntau hauv cov hlua khi los yog rub lub nruas kom tsim tau lub tshuab txuas zog. Connectors yuav txuas rau 900 micron buffered fibers hauv cables cables, tab sis qhov txiav tsis yog siv raws li cov uas ua rau cov cab cab, yog li lawv yuav tsum muab tso rau hauv lub khauj khaum lossis cov thawv rau kev tiv thaiv. Cov fais fab ntawm 250 micron buffered cables tsis tuaj yeem kaw tsis tau yooj yim yog tias lawv muaj qhov cuab yeej hu ua pob khoom tawg lossis cov khoom furcation, qhov twg txhua qhov fib fais los ntawm lub raj yas loj. Feem ntau xoob raj thiab hlua cab raug tshem tawm los ntawm kev sib thiav rau ib qho kev tua pigtail.
Cables tau rub nrog connectors twb rau lawv yog, thiab loj yog, koj tuaj yeem nrog ob qhov teeb meem: Ua ntej, qhov ntev yuav tsum yog leej twg. Ntev luv luv thiab koj yuav tsum tau rub ib qho ntxiv (nws tsis raug nqi zoo rau splice), ntev ntev thiab koj khib nyiaj thiab yuav tsum tau muab cov hlua txuas ntxiv. Secondly, cov connectors yuav tsum muaj kev tiv thaiv. Qee cov cable thiab connector tuam txhab muaj cov tsho tiv thaiv los npog cov connectors, tab sis koj tseem yuav tsum tau ceev faj ntau hauv cov cab cab. Tej zaum koj yuav xav txog qhov xaus thiab rub tawm qhov kawg uas tsis muaj kev txwv kom tsis txhob muaj cov teeb meem.
Thaum xav tau cov cuab yeej tshwj xeeb, siv lawv raws li qhov tsim nyog. Thiab thaum lub installation tiav lawm, cov hlua khi yuav tsum tau them nrog lub plua plav kom tsim nyog thiab muab khaws cia rau hauv qhov chaw nyab xeeb uas tos kev kuaj lossis txuas mus rau cov khoom siv.
Fiber termination kuj yuav tsum yog ntawm txoj cai style kom sib npaug nrog cov cuab yeej cuam tshuam thiab tiv thaiv tawm tsam qhov chaw uas lawv raug ntsia. Thaum ob peb hom sib txuas yog txhua yam tau txais, los yog tsuas yog muaj ib hom khoom sib txuas nkaus xwb, tiam sis tsis zoo rau lub installation, tus installer yuav tsum sib tham txog txoj hauj lwm ntawm lwm hom ua ntej ua tus tsim.
