Kawm paub ntau ntxiv txog cov khoom siv hluav taws xob fiber ntau

Optical fiber txuas yog qhov feem ntau dav siv khoos phis tawm dhau los hauv cov khoom siv hauv kev sib txuas lus fiber ntau. Cov kab ke kho qhov muag fiber ntau yog tsim ntawm peb ntu: ob qho khoom siv kho qhov muag thiab ib tus txuas ntxiv. Ob txoj hlua hluav taws xob txuas rau hauv ob txoj hlua khi, thiab cov coupler ua lub ntsej muag sib luag. Ib qho ntxiv, lub coupler tau nruab nrog cov hlau lossis cov xim tsis yog xim hlau kom yooj yim rau kev teeb tsa thiab kho ntawm lub txuas.

Optical fiber txuas ntawm cov sib txawv sib txawv tuaj yeem tso rau ntawm ob qhov kawg ntawm lub tshuab hluav taws xob kho qhov muag kom paub cov kev hloov pauv ntawm FC, SC, St, LC, MTRJ, MPO, E2000 thiab lwm yam cuam tshuam sib txawv. Nws yog dav siv hauv optical fiber faib ncej (ODF), cov khoom siv sib txuas lus fiber ntau, cov twj paj nruag, thiab lwm yam, nrog kev ua tau zoo, ruaj khov thiab kev ntseeg tau.

Qhov ob xaus ntawm qhov hloov kho siv tau tuaj yeem txuas nrog ntau hom ntawm cov kho qhov muag fiber ntau, thiab muab cov kab sib txuas ntawm APC kawg ntsej muag. Lub tshuab tso ob lossis ntau qhov txuas tau tuaj yeem ua rau thaj chaw teeb tsa tau zoo thiab txuag tau qhov chaw.

Yam khoom

Raws li qhov sib txawv ntawm cov hluav taws xob fiber ntau txuas, cov hluav taws xob kho qhov muag hluav taws xob tuaj yeem muab cov khoom siv hluav taws xob fiber ntau txuas.

Cov khoom siv haum fiber txuas yog FC, SC, St, LC, MTRJ, E2000, thiab lwm yam

Muaj peev xwm siv lub ntsej muag ntawm cov khoom siv hluav taws xob fiber ntau yog PC, UPC, APC, thiab lwm yam

GG quot; SC" sib koom tes yog txheej txheem square sib koom ua ke, uas yog ua los ntawm engineering plastics thiab muaj qhov zoo ntawm qhov kub tsis kam thiab tsis yooj yim rau oxidize. Qhov cuam tshuam kho qhov muag ntawm cov khoom siv sib kis sab feem ntau siv SC txuas.

Cov duab ntawm" LC" kev sib koom ua ke zoo ib yam li ntawm SC sib koom tes, tab sis me dua ntawm SC ntawm kev sib koom ua ke.

GG quot; FC" txuas yog hlau sib koom tes, uas feem ntau siv ntawm ODF sab, thiab lub sijhawm pluggable ntawm cov hlau txuas yog ntau tshaj li ntawm cov yas sib koom tes.

Sib tsoo hom

PC sib tsoo dav hlau yog ib txoj kev sib tsoo lub ntsej muag kawg rau qhov chaw kheej kheej. Thaum kawg lub ntsej muag ntawm optical fiber yog hauv av los ntawm PC, qhov ntxig tsis txaus yog me me thiab lub teeb liab ruaj khov. Vim tias qhov sib tsoo, qhov pom ntawm lub ntsej muag kawg lub ntsej muag tuaj yeem txo qis thiab rov qab poob tuaj yeem txhim kho.

SPC sib tsoo lub dav hlau, tshwj xeeb kev sib tsoo tshuab ua rau xa rov qab poob ntawm UPC sib tsoo ntau dua 50dB, tshwj xeeb tshaj yog haum rau SDH lub zog loj.

APC (angel PC) lub dav hlau lapping yog txoj kev sib tsoo lub ntsej muag kawg rau hauv qhov chaw 8 ° kheej kheej. Nws tuaj yeem ua kom lub teeb pom kev zoo tsom mus rau sab nraud ntawm cov hluav taws xob fiber ntau, thiab tuaj yeem txais cov xa rov qab poob ntau dua 60dB. Hom qauv no muaj cov tsis tau ntxig thiab feem ntau siv rau kev sib kis duab, tshwj xeeb tshaj yog rau cov kab ke kev kub ceev, optical fiber CATV, EDFA, thiab lwm yam

Optical fiber txuas yog cov cuab yeej siv kom tshem tawm (txav tau) ntawm cov khoom sib txuas ntawm cov khoom siv fiber ntau thiab optical fiber. Nws txuas rau ob sab kawg ntawm lub ntsej muag ntawm optical fiber kom meej meej, kom lub teeb hluav taws xob tawm los ntawm kev xa cov khoom siv fiber ntau tuaj yeem txuas rau qhov tau txais cov fiber ntau kom tau qhov siab tshaj plaws, thiab qhov cuam tshuam rau lub kaw lus los ntawm nws cov kev cuam tshuam hauv qhov kho qhov muag txuas yog tsawg heev. Qhov no yog qhov yuav tsum tau ua raws li ntawm lub laj kab fiber ntau txuas. Rau qee qhov, qhov kho qhov muag hluav taws xob fiber ntau kuj cuam tshuam kev cia siab thiab ua tiav ntawm qhov kho qhov muag xa hluav taws xob.

Yam ntxwv

1. Los ntawm 100% kho qhov muag pom, lub tes tsho ceramic (zirconia) lub tes tsho yog ua tiav los ntawm cov khoom lag luam high-precision tshuab cuab yeej, nrog cov khoom lag luam siab thiab ua tiav qhov chaw axis, kom ntseeg tau cov khoom coaxiality thiab Homo roundness raug coefficient.

2. Kev sib xyaw ua ke sab hauv tus qauv, cov qauv tsim tshwj xeeb, qauv yooj yim, siv tau yooj yim, yooj yim sib dhos thiab txhim kho kev ua haujlwm

3. Muaj kev ruaj khov zoo, tso me me poob hauv ntsaws txuas ntxiv thiab rub xeem

Optical fiber adapter tau txuas ob lub txuas kom xa tau qhov hluav taws xob tshaj plaws thiab txo qhov poob. Nws yog tsuas yog siv rau kev sib txuas ntawm optical cable mus rau optical cable lossis cable rau khoom siv. Siab txuam thiab hloov pauv hom adapter, suav nrog tus txiv neej tshwj xeeb poj niam adapter. Nws muaj qhov zoo ntawm kev poob qis ua tsis tau zoo, kev sib hloov zoo, rov ua dua zoo, siab kub tsis kam, acid thiab alkali tsis kam thiab kev ua haujlwm ruaj khov.

Kev faib tawm ntawm cov khoom siv fiber ntau kho qhov muag

Muaj ntau cov qauv ntawm cov khoom siv fiber ntau txuas. Cov khoom siv txuas hauv EPON network yog APC txuas. Lub ntsej muag kawg ntawm APC yog hauv av mus rau kaum ntawm 8 degrees los txo cov kev cuam tshuam. Kev lag luam tus qauv xa rov qab poob yog - 60dB. APC cov khoom siv nrog qhov ntsuas, lub kaum ntsees preset, qhov kev npaj ua ntej lub vojvoog thiab lub tes tsho ua ntej polished muab kev ua tau zoo dua thiab tuaj yeem siv nrog cov txig tseem ceeb nrog nrog lossis tsis muaj NTT-FC tus qauv.

Raws li cov ntawv thov sib txawv thiab cov cai ntawm cov kho qhov muag hluav taws xob fiber ntau, txhawm rau kho ntawm ntau cov kab hluav taws xob, cov hluav taws xob kho qhov muag kuj tau tsim kom muaj ntau yam zoo ntawm cov ntuag hluav taws xob. Tus hloov kho tuaj yeem txuas ntau hom kev kho qhov muag ntawm cov kab hluav taws xob txuas ua ke, thiab muab qhov sib txuas ntawm cov ntu sib txawv. Ob chav sib txuas lossis ntau qhov kev sib txuas tuaj yeem txhim kho cov teeb meem ntawm kev teeb tsa. Raws li cov txheej txheem sib txawv thiab sib dhos, cov kho qhov muag fiber ntau tuaj yeem raug faib ua cov qauv hauv qab no: FC, SC, ST, LC, FC-SC, FC-ST, ST-SC, ntxiv rau qee lub npav rau adapter tsheb npav.

FC optical fiber adapter --- cov qauv ntxiv sab nraud yog hlau tes tsho, thiab txoj kev nrawm nrawm yog ntsia hlau sia. FC hom txuas adopts lub qab kawg ntawm tej hub tus pin. Cov hom kev txuas no muaj qhov zoo ntawm cov qauv yooj yim, kev ua haujlwm yooj yim thiab kev yooj yim. Txawm li cas los xij, qhov kawg fiber yog nkag rau plua plav thiab yooj yim los ua Fresnel kev xav, uas ua rau nws nyuaj los txhim kho kev ua tau zoo ntawm kev xa rov qab. Tom qab ntawd, cov hom kev txuas no tau txhim kho los ntawm kev siv tus pin (PC) nrog spherical taub qab lub ntsej muag, tab sis tus qauv sab nraud tsis hloov, uas zoo heev txhim kho qhov ua tau zoo ntawm cov tsis nkag thiab poob rov qab.

SC optical fiber adapter --- nws lub plhaub yog cov duab plaub, thiab cov qauv ntawm tus pin thiab txuas lub tes tsho siv tau yog ib yam zoo ib yam li FC hom. Ntawm lawv, lub ntsej muag kawg ntawm tus pin feem ntau grinded los ntawm PC lossis APC hom, thiab hom fastening yog plug-in latch yam tsis muaj kev sib hloov. Nws tau nruab nrog cov hlau ntuag, uas yooj yim rau kev zais zais. Cov hom kev sib txuas no muaj qhov zoo ntawm tus nqi qis, yooj yim ntsaws hauv kev ua haujlwm, hloov me me ntawm kev nkag mus tsis tau, lub zog loj thiab qhov siab ntawm lub plahaum siab.

St optical fiber adapter --- nws yog lub khawm hom txhav tas tus qauv nrog tus yuam sij los xyuas kom meej qhov sib luag thaum sib txuas, nrog lub zog tensile zoo. Hlau qhov chaw tseem ceeb txhim kho qhov rov ua dua thiab ua kom ruaj khov ntawm lub adapter. Precise ceramic los yog tooj liab lub tes tsho yog siv los xyuas kom ntev lub sij hawm ruaj khov kho tshuab thiab optical zog. Rectangular qauv, kov thiab riveting, yooj yim rau kev txhim kho thiab siv.

LC optical fiber adapter --- nws yog ua los ntawm kev yooj yim los ua haujlwm modular jack (RJ) latch mechanism. Qhov luaj li cas ntawm tus pin thiab lub tes tsho yog me me, uas txhim kho qhov ntom ntawm cov kab hluav taws xob hauv cov kab hluav taws xob hauv cov kab hluav taws xob fiber ntau faib ua ke. Precision ceramic lub tes tsho ua kom ntev lub sij hawm ruaj khov kho tshuab thiab kho qhov muag.

HTF muab ntau yam khoom siv kho qhov muag fiber ntau. Txoj haujlwm ntawm kho qhov muag cov nplai hluav taws xob hauv cov kab ke sib txuas lus fiber ntau yog qhov tseem ceeb raws li lub zog txuas rau hauv Circuit Court.
