mpo vs lc qhov txawv yog dab tsi?

Yog tias koj tau siv txhua lub sijhawm nyob ib puag ncig cov ntaub ntawv chaw cabling lossis tsuas yog sim xaj fiber ntau thaj cables online, koj yuav tau khiav mus rau ob lub npe no:LC thiab MPO. Thiab ncaj ncees? Thawj zaug kuv pom MPO connector ntawm tus neeg, kuv xav tias ib tug neeg tau welded ib pawg ntawm fibers ua ke tsis ncaj ncees lawm. Nws zoo li txawv. Loj. Tsis muaj dab tsi zoo li cov LC plugs me me uas kuv tau siv los.

Tab sis ntawm no yog qhov -lawv tsis yog cov neeg sib tw hauv txoj kev xav. Ntau dua li cov kwv tij txheeb ze nrog ntau txoj haujlwm sib txawv.

LC connector: txhua tus nyiam

LC stands rau Lucent Connector. Lucent Technologies tau tsim nws rov qab rau hnub, thiab nws daig ncig vim nws tsuas yog ... ua haujlwm. Me hneev taw . 1.25mm ferrule. Push-rub lub tshuab uas tsis xav kom koj tig los yog ntsia hlau dab tsi. Koj nias rau hauv, koj ua tiav.

Cov neeg feem coob ntsib LC ua ntej. Nws nyob txhua qhov chaw -cov koom tes sib koom tes, chav sib tham, cov chaw khaws ntaub ntawv me, SFP transceivers. Lub duplex version (ob lub LC connectors koom ua ke) tswj koj tus qauv xa tawm - thiab - tau txais kev teeb tsa yam tsis muaj qhov ua yeeb yam.

Dab tsi ua rau LC nrov tsis yog qee qhov txuj ci tseem ceeb. Nws yog cov khoom siv. Qhov khoom me me piv rau cov laus txuas xws li SC lossis ST. Koj tuaj yeem ntim ntau cov chaw nres nkoj rau hauv lub vaj huam sib luag. Qhov ntawd tseem ceeb thaum rack qhov chaw raug nqi nyiaj.

MPO: ib qho uas ua rau tib neeg tsis meej pem

 

MPO txhais tau tias Multi-fiber Push-On. Los yog Multi-fiber Push-On/Pull-Tawm yog tias koj xav tau lub npe tag nrho tsis muaj leej twg siv tiag tiag.

Ntawm no yog qhov uas nws tau nthuav.

MPO connector tsis nqa ib los yog ob fibers. Nws nqa 8, 12, 24-qee zaum txog 72 fibers hauv ib lub ntsaws. Ib lub voj voog txuas. Ntau fibers lined nyob rau hauv ib tug precision ferrule. Lub tswv yim yog ntom. Raw, txhoj puab heev ntom.

Vim li cas leej twg xav tau qhov no? Vim cov chaw zov me nyuam niaj hnub no yog vwm . 40 gig links . 100 gig links . 400 gig thiab tshaj. Ntawm qhov ceev no, koj xav tau kev sib txuas optics-ntau fibers kis ib txhij. Kev khiav ib tus LC cables rau txhua qhov fiber ntau yuav yog kev tswj xyuas kab npau suav phem. Ntseeg kuv. Kuv tau pom cov duab "ua ntej" los ntawm cov chaw zov me nyuam uas tau sim.

Qhov loj me tseem ceeb (tab sis tsis yog koj xav li cas)

 

LC ferrule: 1.25mm txoj kab uas hla.

MPO: duab plaub ferrule vaj tse ntau fibers nyob rau hauv ib tug linear array.

Koj yuav xav tias loj dua=muaj peev xwm zoo dua, thiab technically yog. Tab sis MPO connectors tsis yog "loj" nyob rau hauv txoj kev laus connectors loj. Lawv yog cov compact rau lawv ua. MPO-12 siv tib lub vaj huam sib luag qhov chaw raws li ib qho SC connector-tab sis nws txav kaum ob npaug ntawm fiber ntau.

Cov engineering hauv qab no yog tiag tiag ntse. Precision qhia pins. Floating ferrule tsim nyob rau hauv hwm versions (uas yog qhov twg MTP trademark los ntawm US Conec tuaj). Cov khoom no xav tau micron - theem kev sib raug zoo hla ntau lub fibers ib txhij. Tau qhov kev sib dhos tsis raug, thiab koj tab tom ntsia ntawm cov lej poob uas yuav ua rau koj quaj.

Thaum koj yuav tau siv txhua tus

LC dominates hauv:

Enterprise networks qhov twg 10G yog tus qauv

Kev teeb tsa me me uas tsis xav tau cov fiber ntau suav

Cov txheej txheem qub txeeg qub teg- tons ntawm cov txheej txheem uas twb muaj lawm siv LC

Zoo nkauj npaum li cas SFP los yog SFP + transceiver teeb

MPO tshwm sim thaum:

Koj tab tom tsim 40G / 100G / 400G txuas hauv cov ntaub ntawv chaw

Ua ntej- cov kab hluav taws xob kaw tau ua rau muaj txiaj ntsig rau koj qhov kev xa tawm

Qhov chaw nruj heev uas khiav kaum ob ntawm tus kheej cables tsis ua tau

Koj tab tom txuas QSFP transceivers

Tab sis ntawm no yog ib qho nuance feem ntau cov lus qhia hla dhau: MPO thiab LC feem ntau ua haujlwm ua ke. Cov chaw zov me nyuam feem ntau siv MPO lub cev cables rau cov pob txha khiav, tom qab ntawd tawg tawm mus rau LC ntawm thaj chaw ntawm cov kab ntawv los yog cov kab hluav taws xob. MPO-12 mus rau 6xLC-duplex hloov dua siab tshiab yog ib qho qauv kev lag luam.

Yog li nws tsis yog LC piv rau MPO. Nws yog LCthiabMPO, nyob ntawm seb koj nyob qhov twg hauv cov nroj tsuag cable.

Qhov polarity mob taub hau

Kuv yuav tsum tau hais txog polarity vim tias nws ua rau tib neeg mus tas li.

Nrog LC, polarity yog ncaj nraim. Koj tau txais ob lub fibers - xa thiab tau txais. Tig lub connector orientation los yog siv ib tug crossover cable. Ua tiav.

MPO? Hmoov zoo.

Thaum koj muaj 12 fibers nyob rau hauv ib lub connector thiab lawv yuav tsum tau kab kom raug ntawm ob qho tib si kawg -nrog rau kev sib txuam kom tau txais ntawm txhua tus khub- tej yam yuav nyuaj sai. TIA-568 txhais peb txoj hauv kev polarity (A, B, thiab C) rau kev tsim cabling. Txhua tus yuav tsum tau tshwj xeeb cable configurations. Sib tov lawv thiab koj qhov txuas tsis ua haujlwm lossis muaj fibers tham tsis muaj leej twg.

Cov dot dawb ntawm MPO connectors marking txoj hauj lwm 1 muaj nyob rau qhov tseeb vim li cas. Cov yuam sij. Pin orientation. Txiv neej thiab poj niam connectors. Muaj tag nrho cov txheej txheem los khaws cov khoom sib koom ua ke, thiab nws ua haujlwm, tab sis muaj qhov kev kawm nkhaus.

Kev ua tau zoo: dab tsi cov specs tsis qhia koj

Ob leeg LC thiab MPO muaj kev ua tau zoo heev thaum tsim khoom raug. Cov kev nkag tsis zoo ntawm qhov ntsuas qhov ntsuas ntawm 0.1-0.15 dB rau cov khoom siv LC zoo, tej zaum 0.25-0.35 dB rau MPO (ib fiber ntau).

Nov yog qhov tsis muaj leej twg tshaj tawm: MPO connectors nyuaj dua kom huv.

Lub ferrule uas muaj 12 lossis 24 fiber ntau xaus? Txhua tus yuav tsum muaj kev sib kis -dawb. Ib qho spec ntawm plua plav ntawm ib qho fiber ntau tuaj yeem ua rau koj qhov txuas tag nrho. Thiab vim tias thaj chaw saum npoo loj dua thiab cov duab geometry ntau txoj hauv kev, cov cuab yeej siv fiber ntau siv qee zaum tsis txaus.

Kuv tau hnov ​​​​cov kws tshaj lij hais tias MPO connectors yog "kev saib xyuas siab" thiab ua siab ncaj uas ncaj ncees. LC muaj ib qho fiber ntau kawg los ntxuav. MPO muaj ... ntau qhov chaw saum npoo rau tej yam mus tsis ncaj ncees lawm.

Hwm MTP connectors nyob rau qee qhov no nrog cov ntaub ntawv zoo dua ferrule thiab nruj dua, tab sis lawv raug nqi ntau dua. Qee zaum tseem ceeb dua.

Nqi thiab muaj

LC connectors yog pheej yig. Zoo li, kuj ceeb tias pheej yig rau precision optical Cheebtsam. Kev sib tw ua rau tus nqi qis dua xyoo dhau los. Koj tuaj yeem tau txais LC cords zoo rau ob peb las txhua.

MPO lub cev cables? Dab neeg sib txawv. Cov connectors lawv tus kheej kim dua. Cov kev xav tau precision yog siab dua. Thiab koj tab tom them rau ntau qhov kev txiav tawm fiber ntau hauv ib lub rooj sib txoos. Ib qho zoo 24-fiber MPO lub cev cable raug nqi tiag tiag.

Tab sis -thiab qhov no yog qhov kev sib cav sib cav cov ntaub ntawv chaw tsim khoom tsim ua- kev teeb tsa ua haujlwm rau ib lub MPO lub cev piv rau kaum ob cais LC cables yuav tsum muaj nyob rau hauv. Lub sij hawm yog nyiaj. Plug-thiab-ua si ua ntej- kaw cov tshuab muaj tshwj xeeb vim yog lej no.

Lub neej yav tom ntej (los yog dab tsi peb tab tom hu nws tam sim no)

LC tsis mus qhov twg. Muaj ntau ntau lub hauv paus. Muaj ntau yam khoom siv nrog SFP chaw nres nkoj. Nws yuav nyob twj ywm tus neeg ua haujlwm txuas rau ib zaug - cov ntawv thov channel.

MPO tab tom loj hlob . 400G xa tawm siv 8-fiber thiab 16-fiber MPO. Newer heev-me me-form-factor connectors (xws li SN-MT thiab MMC) yog qhov hloov pauv MPO cov ntsiab lus nrog qhov ceev dua. AI cov chaw zov me nyuam nrog lawv cov kev xav tau bandwidth insane yog tsav qhov kev thov rau cov fibers sib npaug ntau dua.

Lub connector toj roob hauv pes yuav evolving. Tab sis rau feem ntau lub hom phiaj niaj hnub no, paub txog thaum twg yuav ncav cuag LC piv rau MPO- lossis ob qho tib si - npog 95% ntawm cov xwm txheej.

Tsis muaj leej twg sau ntawv hlub txog fiber ntau connectors. Tab sis yog tias lawv tau ua, LC yuav yog tus khub txhim khu kev qha uas ib txwm nyob ntawd, thiab MPO yuav yog tus neeg siab nyiam uas tshwm sim thaum cov ceg txheem ntseeg siab.

Siv qhov twg yog qhov ua rau muaj kev nkag siab zoo rau koj qhov xwm txheej. Los yog ob leeg. Feem ntau ob leeg.
