PC, UPC, APC Fiber Connector Hom Sib Piv thiab Kev Xaiv
Taw qhia
Ua ntej sib tham txog PC, UPC thiab APC fiber ntau txuas, nws yuav tsum paub tias ob lub ntsej muag kawg ntawm cov fiber ntau yuav tsum tau txuas ncaj qha txhawm rau txhawm rau ua kom qhov sib txuas ntawm fiber ntau lub teeb tawm los ntawm kev xa cov fiber ntau mus rau qhov tau txais fiber ntau. Qhov tseeb ntawm kev sib txuas feem ntau yog nyob ntawm qhov zoo ntawm lub cev kev sib txuas ntawm fiber ntau, ob qho tib si cuam tshuam rau qhov poob thiab rov poob ntawm fiber. Qhov kev ua tau zoo ntawm cov fiber ntau optical yog ntsuas los ntawm qhov tsis zoo thiab rov qab poob. Kev sib txuas ntawm lub cev ntawm fiber ntau, qee zaum hu ua qhov sib txawv polished fiber ntau lub ntsej muag duab, yog li tseem ceeb rau kev ua haujlwm ntawm fiber ntau. Raws li hom polishing ntawm lub connector, fiber optic thaj qaum tau muab faib ua PC, UPC thiab APC hom. Peb txoj kev polishing ntawm fiber ntau optic thaj qaum yog qhov sib txawv hauv cov qauv thiab kev ua tau zoo, feem ntau ntawm kev poob thiab rov qab poob. Ntawm cov no, APC yog nyob deb ntawm hom nrov tshaj plaws ntawm polishing.
PC Connector yog dab tsi?
Lub sij hawm "PC connector" yog hais txog lub cev sib cuag fiber ntau connector, uas ua rau ob lub fibers 'qhov kawg ntsej muag los ua ncaj qha rau ib leeg. PC connector siv microspherical polished connectors nrog cov xim dub. Lub fiber-kawg nto tau polished kom zoo li lub convex kheej kheej. Txawm hais tias lub vojvoog loj ntawm curvature, nws zoo nkaus li tiaj tus. Vim tias cov tub ntxhais kho qhov muag fiber ntau nyob ntawm qhov siab tshaj plaws ntawm qhov khoov, qhov sib txawv ntawm cov khoom siv fiber ntau tau txo qis, tso cai rau kev sib cuag ntawm ob lub ntsej muag fiber ntau.
Fiber optic PC connector yog qhov qub tshaj plaws ntawm peb lub connectors. Kev tsim kho ntawm lub ntsej muag ze li ntawm lub ntsej muag tsis txaus los txiav txim siab rov qab poob. PC connector raug tso tseg nyob rau hauv kev pom zoo ntawm txhim kho UPC thiab APC connectors vim hais tias nws muaj ib tug loj npaum li cas rov qab poob ntawm tsawg kawg yog -40dB.
UPC Connector yog dab tsi?
UPC connector yog ib qho kev txhim kho thiab kho dua tshiab ntawm PC. "UPC" yog lub ntsiab lus ntawm Ultra Physical Contact. UPC fiber ntau connector yog ib qho evolution ntawm lub outdated PC connector nrog ib tug xiav xim. Nws tseem muaj qhov convex spherical nto, tab sis nws lub vojvoog ntawm curvature yog qis dua li ntawm PC connector, muab nws zoo li dome-zoo li ntau dua. Tsis tas li ntawd, nws ua rau siv txoj kev tshaj tawm kev txhim kho, uas txhim kho fiber ntau polishing. Yog li ntawd, UPC polish connector muaj qis rov qab poob ntawm -50dB dua li PC connector. Yog li ntawd, UPC polish connector, piv rau PC connector, muaj qhov rov qab poob qis dua ntawm -50dB.
APC Connector yog dab tsi?
APC connector yog qhov nrov tshaj plaws fiber ntau connector hom siv niaj hnub no. "APC" sawv cev rau Angled Physical Connector. Nrog rau xim ntsuab, 8-degree bevelled kaum sab xis ntawm lub ntsej muag kawg ntawm lub ntsej muag yog qhov tshwj xeeb yog qhov zoo rau kev ruaj ntseg ntawm lub ntsej muag fiber ntau. Qhov rov qab poob ntawm fiber ntau optic APC connector feem ntau yog -60dB, uas yog qhov tsawg tshaj plaws ntawm peb hom UPC, APC thiab PC fiber ntau connectors.
Ntau dua li rov qab xav txog lub teeb pom kev zoo, APC connector considerably txo qis fiber ntau rov qab los ntawm kev tso cai rau lub teeb pom kev rau cov fiber ntau cladding vim yog txoj kab nqes kawg ntawm lub ntsej muag. Nws ib txwm muaj qhov poob rov qab ntawm -60dB, uas yog qhov qis tshaj ntawm peb hom UPC, APC thiab PC fiber ntau txuas.
Yuav Ua Li Cas Xaiv Ntawm UPC thiab APC?
APC connector yog pom zoo dua yog tias koj daim ntawv thov, xws li FTTx thiab WDM system daim ntawv thov, yog rhiab heev rau rov poob. Muab hais tias UPC connectors tsis tshua kim tshaj APC connector, nws tuaj yeem yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov tsis tshua muaj siab vim nws tuaj yeem muab kev ua tau zoo uas yuav luag zoo ib yam rau APC. Yog li, nws yog qhov tseeb tias UPC connector nquag siv hauv fiber ntau niaj hnub no.
