Fiber optic termination yog txheej txheem ntawm kev npaj ib tug liab qab optical fiber yog li nws muaj peev xwm ua phooj ywg nrog ib tug connector, splice vaj tse, los yog tej yam khoom siv. Txhua qhov kev sib txuas hauv ib lub network fiber ntau - los ntawm thaj vaj huam sib luag hauv qhov chaw cov ntaub ntawv mus rau lub xaim xaim ntawm tus neeg siv khoom lub tsev - nyob ntawm qhov kev txiav tawm uas tswj cov teeb liab poob, txo qis kev xav, thiab tuav tau ntau xyoo ntawm kev pabcuam.
Tau txais txoj cai txiav tsis yog tsuas yog ua kom tiav cov kab. Nws yog hais txog kev xaiv txoj kev uas phim koj cov peev nyiaj txuas, ib puag ncig, thiab kev ua haujlwm tiag tiag, tom qab ntawd txheeb xyuas qhov tshwm sim ua ntej koj tawm ntawm qhov chaw. Cov lus qhia no suav nrog cov txheej txheem tseem ceeb ntawm kev txiav tawm, cov cuab yeej txhua tus xav tau, qib siab - txheej txheem koj tuaj yeem hloov kho rau txhua qhov txuas txuas, thiab qhov ua yuam kev uas ua rau rov ua haujlwm dua.
Dab tsi yog Fiber Optic Termination?
Ntawm qhov ua tau zoo, fiber ntau optic txiav tawm tsim qhov sib cuam tshuam ntawm cov khoom siv fiber ntau thiab lwm qhov ntawm lub network. Qhov ntawd interface tuaj yeem yog ib qhofiber ntau optic connector- ib tug tshem tau txhua yam sib dhos ua nyob ib ncig ntawm ib tug precision ferrule - los yog ib tug splice uas mus tas li koom nrog ob fibers. Cov khoom sib txuas tau siv txhua qhov chaw uas koj xav tau los ua phooj ywg thiab tsis sib koom qhov txuas: thaj vaj huam sib luag, cov khoom siv chaw nres nkoj, cov ntsiab lus nkag. Splices yog siv rau qhov kev sib txuas yuav tsum nyob ruaj khov: nruab nrab- ncua kev koom nrog, kaw rov- nkag, thiab pigtail txuas hauv cov ntawv xov xwm lossis cov ntaub thaiv npog.
CovFiber Optic Association (FOA)txhais cov connector poob raws li qhov poob ntawm ib khub niam txiv ntawm cov connectors qhia nyob rau hauv dB, hais txog tias kev ntsuas poob nyob ntawm ob qho tib si connector nyob rau hauv kev sim thiab cov ntaub ntawv connector nws mates nrog. Qhov kev nthuav dav no tseem ceeb vim tias nws txhais tau tias kev txiav tsis zoo yog ib txwm txheeb ze - ib qho txuas tsuas yog zoo li qhov kev sib txuas nws ua.
Vim li cas thiaj tsim nyog Termination Matters: Insertion Poob thiab Rov Los Poob
Ob qhov kev ntsuas txhais tau tias qhov kev txiav tawm ua haujlwm li cas: qhov poob qis thiab rov qab poob.
Insertion poobyog lub hwj chim kho qhov muag poob thaum lub teeb hla kev sib txuas. Txhua tus khub txuas, splice, thiab 'meter' ntawm cable ntxiv qhov poob rau qhov txuas. Hauv qabANSI/TIA-568.3-E, qhov siab tshaj plaws tso cai poob rau ib khub niam txiv ntawm tus qauv - qib connectors yog 0.75 dB, thiab qhov siab tshaj plaws rau kev sib txuas yog 0.3 dB. Hauv kev xyaum, zoo- ua cov nplaum / txhuam cov khoom sib txuas ntawm lub Hoobkas thaj cords ib txwm tuaj hauv qab 0.3 dB rau ib khub niam txiv.
Rov qab poob(tseem hu ua optical rov poob poob, lossis ORL) ntsuas seb lub teeb pom kev rov qab mus rau qhov twg. Kev polishing tsis zoo, qhov khoob hauv huab cua, kev sib kis, thiab tawg ferrule ntsej muag tag nrho nce rov qab -xav txog.

Lwm hom xws liFCthiabSTtseem muaj nyob rau hauv cov cuab yeej cuab tam thiab qee cov ntawv thov tshwj xeeb.
Kuv yuav ua li cas thiaj paub yog tias kuv qhov kev txiav tawm zoo txaus?
Kev kuaj pom qhov muag thiab kev kuaj qhov poob yog ob qho kev kuaj xyuas uas tseem ceeb. Tshawb xyuas lub ntsej muag kawg hauv qab lub tshuab ntsuas fiber ntau thiab paub meej tias nws ua tau raws li IEC 61300-3-35 cov qauv kev huv. Tom qab ntawd ntsuas qhov poob qis nrog OLTS thiab sib piv cov txiaj ntsig tawm tsam koj cov peev nyiaj txuas. Yog tias koj tab tom ua qhov kev lees paub rau cov txheej txheem cabling, TIA-568.3-E Tier 1 (poob thiab ntev) yog qhov tsawg kawg nkaus; Tier 2 (OTDR) kev xeem ntxiv cov ntsiab lus ntawm cov xwm txheej rau cov ntaub ntawv thiab kev daws teeb meem.
Kuv puas tuaj yeem splice ib qho - hom fiber ntau rau multimode fiber ntau?
Lub cev, yog - fusion splicer tuaj yeem koom nrog ob lub fibers. Optically, nws tsim ib qho tseem ceeb hom mismatch uas ua rau poob siab thiab kev ua tau zoo unpredictable. Tib - hom thiab multimode fibers yuav tsum tsis txhob muab sib xyaw rau hauv tib qhov txuas. Yog tias koj xav tau kev hloov pauv ntawm hom fiber ntau, siv lub tshuab hloov pauv xov xwm lossis cov khoom siv kho qhov muag uas txhawb nqa cov fiber ntau tsim nyog ntawm txhua sab.
Dab tsi yog qhov feem ntau ua rau fiber ntau connector tsis ua hauj lwm?
Kev kis kab mob. Plua plav, roj, thiab cov khib nyiab microscopic ntawm lub ntsej muag kawg ua rau qhov kev tso tawm ntau dhau thiab rov qab- rov qab, thiab tuaj yeem ua rau lub ferrule puas tsuaj tas mus li thaum ob qhov sib txuas sib kis tau sib txuas. Kev tshuaj xyuas thiab ntxuav ua ntej txhua qhov kev sib tw sib tw yog qhov kev coj ua zoo tshaj plaws rau kev tiv thaiv kev sib txuas - cuam tshuam txog kev ua tsis tiav.
Kuv puas xav tau OTDR rau txhua txoj haujlwm txiav?
Tsis tas li. Ib qho OLTS (lub teeb ci thiab lub ntsuas hluav taws xob) yog txaus rau Tier 1 poob ntawv pov thawj ntawm feem ntau txoj haujlwm. Ib qho OTDR ua ib qho tseem ceeb thaum koj xav nrhiav ib qho txhaum cai, ntsuas tus kheej splice los yog connector poob, sau cov fiber ntau txoj kev rau cov ntaub ntawv, los yog xyuas rov qab poob. Rau kev xa tawm loj lossis tseem ceeb, kev sim OTDR tau pom zoo pom zoo txawm tias tsis tas yuav tsum nruj.

Fiber optic txiav tawm yog qhov kev txiav txim siab ua haujlwm, tsis yog kev ua haujlwm kho tshuab xwb. Txoj kev uas koj xaiv - nplaum / polish, tsis muaj -epoxy, splice- ntawm connector, pigtail splice, los yog ua ntej -Tawm los ua ke - yuav tsum tau tsav los ntawm kev sib txuas pob nyiaj siv, cov kev xav tau ntawm kev xav, cov txuj ci thiab cov cuab yeej muaj, thiab cov nplai ntawm kev xa tawm.
Txawm li cas los xij, peb qhov kev coj ua cais kev txhim kho txhim khu kev qha los ntawm kev hu xov tooj rov qab: tshuaj xyuas txhua lub ntsej muag kawg ua ntej mating, sim txhua qhov txuas tiv thaiv nws cov peev nyiaj poob, thiab ua raws li tus neeg tsim khoom txuas cov txheej txheem raws nraim. Yog tias koj tab tom ntsuam xyuas cov kev xaiv txiav tawm rau ib txoj haujlwm tshiab, pib los ntawm kev txheeb xyuas koj qhov txuas txuas, hom fiber ntau, lub hom phiaj kev ua haujlwm, thiab cov kev xeem yuav tsum tau ua - tom qab ntawd xaiv cov qauv uas haum.
Rau kev pab xaiv cov connectors, pigtails, adapters, los yog ua ntej -tawm los ua ke rau koj tom ntej xa mus, mus saib pebcov khoom cataloglos yogtiv tauj peb pab pawg engineering.
