Lub luag haujlwm tseem ceeb ntawm fiber ntau optic connector yog txhawm rau txuas ob lub fibers sai sai kom cov teeb liab kho qhov muag tuaj yeem txuas ntxiv mus rau txoj hauv kev kho qhov muag. Fiber optic connectors yog mobile, reusable, thiab yog cov tseem ceeb tshaj plaws thiab feem ntau siv passive Cheebtsam nyob rau hauv kev sib txuas lus kho qhov muag systems.Cov fiber optic connectors tso cai rau ob kawg lub ntsej muag ntawm fiber ntau precisely taub qab-coupled mus cuag lub coupling ntawm lub optical zog tso zis los ntawm kev xa cov fiber ntau mus rau qhov tau txais fiber ntau, thiab cov teebmeem ntawm qhov system vim nws cov kev cuam tshuam yuav tsum tau txo qis. Vim tias sab nraud ntawm cov fiber ntau tsuas yog 125um, thiab lub teeb-dhau yog me dua, ib hom fiber ntau tsuas yog kwv yees li 9um, thiab multimode fiber ntau yog 50um thiab 62.5um, yog li kev sib txuas ntawm cov fibers yuav tsum tau ua kom tiav. ua ke.
Cov khoom tseem ceeb: ferrule
Los ntawm lub luag haujlwm ntawm fiber ntau optic connector, nws tuaj yeem pom tau tias cov khoom tseem ceeb uas cuam tshuam rau kev ua haujlwm ntawm lub connector yog lub ferrule. Qhov zoo ntawm lub ferrule ncaj qha cuam tshuam rau qhov precision chaw docking ntawm ob fibers.Lub ferrule yog ua los ntawm ceramic, hlau los yog yas. Ceramic ferrule yog dav siv, cov khoom tseem ceeb yog zirconium dioxide, uas muaj cov yam ntxwv ntawm thermal stability, siab hardness, siab melting point, hnav tsis kam thiab siab precision. Lub tes tsho yog lwm qhov tseem ceeb ntawm cov khoom sib txuas, thiab lub tes tsho ua haujlwm raws li kev sib haum xeeb los pab txhawb kev sib txuas ntawm cov khoom sib txuas. Lub sab hauv txoj kab uas hla ntawm lub tes tsho ceramic yog me ntsis me dua li sab nraud txoj kab uas hla ntawm lub ferrule, thiab lub tes tsho slitted tightens ob lub ferrules kom meej meej.
Txhawm rau ua kom lub ntsej muag kawg ntawm ob lub fibers zoo sib cuag, ferrule kawg feem ntau yog hauv av rau hauv cov qauv sib txawv. PC, APC, thiab UPC sawv cev rau pem hauv ntej kawg nto qauv ntawm ceramic ferrule. PC yog lub cev tiv tauj, kev sib cuag lub cev.Lub PC yog micro-spherical nto polished thiab polished, qhov saum npoo ntawm lub ferrule yog hauv av rau hauv me ntsis kheej kheej nto, thiab cov tub ntxhais ntawm cov khoom siv fiber ntau yog nyob ntawm qhov siab tshaj plaws ntawm kev khoov kom zoo. ob lub ntsej muag fiber ntau yog nyob rau hauv kev sib cuag ntawm lub cev.APC (Angled Physical Contact) yog hu ua beveled lub cev sib cuag, thiab lub ntsej muag fiber ntau feem ntau yog av mus rau 8 ° bevel. Lub 8 ° angled bevel ua rau lub ntsej muag fiber ntau nruj dua thiab pom lub teeb los ntawm nws lub kaum sab xis rau cladding es tsis txhob rov qab ncaj qha mus rau qhov chaw, muab kev sib txuas zoo dua. UPC (Ultra Physical Contact), super lub cev kawg lub ntsej muag.UPC yog raws li lub PC kom optimize lub ntsej muag kawg polishing thiab nto tiav, lub ntsej muag kawg zoo li ntau dome-puab. Connector kev sib txuas yuav tsum nyob rau hauv tib lub ntsej muag kawg qauv, piv txwv li APC thiab UPC tsis tuaj yeem ua ke, ua rau txo qis kev sib txuas.
Basic tsis muaj: insertion poob, rov poob
Vim qhov txawv ferrule kawg ntsej muag, kev ua tau zoo ntawm cov connector poob kuj txawv. Qhov kev ua tau zoo ntawm cov fiber ntau optic connectors feem ntau yog ntsuas los ntawm ob qho kev tsis sib xws: qhov poob thiab rov qab poob. Yog li, dab tsi yog qhov kev poob qis? Insertion Loss ("IL") yog lub zog kho qhov muag poob vim qhov kev sib txuas.Nws yog tsuas yog siv los ntsuas qhov muag poob ntawm ob lub ntsiab lus ruaj khov hauv fiber ntau, feem ntau yog vim qhov sib txawv ntawm ob lub fibers, qhov sib txawv ntawm qhov ntev ntawm lub fibers. fiber ntau sib koom, qhov zoo ntawm lub ntsej muag kawg, thiab lwm yam. Lub tsev yog qhia hauv decibels (dB). Qhov me dua qhov zoo, qhov kev xav tau dav dav yuav tsum tsis pub ntau tshaj 0.5dB.
Rov Los Loss ("RL") yog hais txog qhov ntsuas qhov ntsuas qhov ua tau zoo. Nws piav qhia txog lub zog poob ntawm optical teeb liab rov qab / rov qab xav. Feem ntau, qhov loj dua qhov zoo dua, tus nqi feem ntau qhia hauv decibels (dB). Ib tug raug APC connector muaj ib tug raug RL nqi ntawm kwv yees li -60 dB thiab ib tug PC connector muaj ib tug raug RL nqi ntawm kwv yees li -30 dB.
Ntxiv nrog rau ob qhov kev ua tau zoo ntawm qhov muag tsis pom kev poob thiab rov qab poob, kev ua haujlwm ntawm fiber ntau optic connector yuav tsum tau them sai sai rau qhov sib hloov, rov ua dua, tensile lub zog thiab kev ua haujlwm kub ntawm fiber ntau optic connector. , tus naj npawb ntawm insertions thiab lwm yam.
Hom Connector
Cov connectors raug faib raws li txoj kev sib txuas: LC, SC, FC, ST, MU, MT, MPO / MTP, thiab lwm yam; Raws li lub ntsej muag fiber ntau: FC, PC, UPC, APC.
LC connector
LC-hom connector yog tsim los nrog ib qho yooj yim-rau-siv modular jack (RJ) latch mechanism. Qhov loj ntawm cov pins thiab lub tes tsho siv hauv LC connector yog 1.25 hli, uas yog qhov loj ntawm SC, FC, thiab lwm yam., yog li qhov loj me sab nraud tsuas yog ib nrab ntawm SC / FC.
SC connector
Lub connector ntawm SC connector ('Subscriber Connector' los yog 'Standard Connector') yog ib tug snap-on standard square connector, uas yog fastened los ntawm plugging thiab unloading, thiab tsis tas yuav tig. Hom connector no yog tsim los ntawm engineering plastics, uas yog pheej yig thiab yooj yim rau ntxig thiab tshem tawm.
FC connector
FC fiber ntau connector (Ferrule Connector) thiab SC connector yog tib qhov loj, tshwj tsis yog tias FC yog ua los ntawm lub tes tsho hlau thiab txoj kev fastening yog ib tug turnbuckle. Cov qauv siv hluav taws xob muaj qhov zoo ntawm cov qauv yooj yim, kev ua haujlwm yooj yim, siv tau yooj yim thiab ua haujlwm ntev, thiab tuaj yeem siv rau hauv qhov chaw muaj kev vibration siab.
ST connector
ST fiber ntau optic connector (Ntiaj Teb Nthuav) muaj ib tug puag ncig txheej casing nrog ib tug 2.5 hli nplhaib-zoo li tus yas los yog hlau casing. Txoj kev fastening yog ib tug turnbuckle, uas yog feem ntau siv nyob rau hauv fiber ntau thav duab.
MTP / MPO connector
MTP / MPO fiber optic connector yog ib hom tshwj xeeb ntawm ntau fiber ntau connector. Cov qauv ntawm MPO connector yog complex, txuas 12 los yog 24 fibers nyob rau hauv ib lub voj voog fiber ntau ferrule. Feem ntau yog siv rau high-density kev twb kev txuas scenarios xws li cov chaw zov me nyuam cov ntaub ntawv.
Ntxiv rau qhov saum toj no, cov khoom sib txuas yog MU connectors, MT connectors, MTRJ connectors, E2000 connectors, thiab lwm yam. SC yog tej zaum qhov feem ntau siv fiber ntau optic connector, feem ntau yog vim nws tus nqi qis. LC fiber ntau optic connectors kuj yog ib tug nquag siv fiber optic connector, tshwj xeeb tshaj yog rau kev twb kev txuas rau SFP thiab SFP + fiber optic transceivers. FC feem ntau yog siv nyob rau hauv ib hom thiab tsis tshua muaj nyob rau hauv multimode fiber ntau. Cov qauv tsim thiab kev siv hlau ua rau nws kim dua. ST fiber ntau optic connectors feem ntau yog siv nyob rau hauv ntev thiab luv luv daim ntaub ntawv xws li tsev kawm ntawv thiab architectural multimode fiber ntau daim ntaub ntawv, enterprise network ib puag ncig, thiab kev siv tub rog.
