1. Yuav ua li cas xaiv optical cable?
Ntxiv nrog rau cov fiber ntau cores thiab fiber ntau hom, kev xaiv ntawm optical cables kuj nyob ntawm qhov chaw siv ntawm cov khoom siv kho qhov muag. Cov qauv thiab txheej txheej ntawm cov khoom siv kho qhov muag yuav tsum tau xaiv.
1. Thaum lub optical cable yog ncaj qha faus sab nraum zoov, nws yog advisable siv xoob-tube armored optical cable. Thaum siv nyiaj siv ua haujlwm, lub raj xoob xoob kho qhov muag nrog lub PE dub txheej txheej nrog ob lossis ntau qhov kev txhawb nqa tuaj yeem siv tau.
2. Thaum xaiv cov kab hluav taws xob kho qhov muag siv rau hauv cov tsev, yuav tsum xaiv cov khoom siv kho qhov muag kaw ntom nti thiab cov xim yuav tsum tau them rau lawv cov nplaim hluav taws kub, cov yam ntxwv lom thiab cov pa taws. Feem ntau, cov nplaim hluav taws tab sis tsis muaj pa luam yeeb (Plenum) lossis hom flammable thiab non-toxic (LSZH) tuaj yeem siv rau hauv cov kav dej lossis qhov chaw ua pa. Cov nplaim-retardant, tsis muaj tshuaj lom thiab tsis muaj pa taws (Riser) yuav tsum tau siv nyob rau hauv qhov chaw raug.
3. Thaum tso cov kab ntsug lossis kab rov tav hauv lub tsev, koj tuaj yeem xaiv cov khoom siv kho qhov muag kaw ntom nti, faib cov khoom siv kho qhov muag lossis cov ceg kho qhov muag uas muaj nyob hauv lub tsev.
4. Xaiv ib hom thiab ntau hom kho qhov muag cables raws li daim ntawv thov network thiab cov ntawv thov kho qhov muag cable. Feem ntau, cov ntawv thov sab hauv thiab luv luv feem ntau yog ntau hom kho qhov muag cables, thiab kev siv sab nraum zoov thiab kev ncua deb yog tsuas yog ib hom kho qhov muag cables.
2. Hauv kev sib txuas ntawm fiber ntau optic, yuav ua li cas xaiv cov ntawv sib txawv ntawm cov kev sib txuas ruaj khov thiab cov kev sib txuas uas txav tau?
Kev sib txuas ua haujlwm ntawm optical fibers yog tiav los ntawm optical fiber connectors. Ib qho kev sib txuas nquag hauv qhov txuas kho qhov muag yog ib qho kev sib txuas ncaj qha. Thaum nws los txog rau kev xaiv ntawm kev sib txuas ntawm cov khoom sib txuas thiab cov kev sib txuas ruaj khov, qhov zoo ntawm cov kev sib txuas ruaj khov yog cuam tshuam nrog cov nqi qis thiab qhov poob qis dua, tab sis tsis yooj yim rau kev hloov pauv, thaum qhov sib txawv yog qhov tseeb rau kev sib txuas ntawm cov khoom txav. Thaum tsim lub network, nws yog ib qho tsim nyog yuav tsum tau hloov pauv kev siv cov kev sib txuas ruaj khov thiab ruaj khov raws li tag nrho cov xwm txheej txuas kom ntseeg tau tias ob qho tib si hloov tau yooj yim thiab ruaj khov, yog li muab kev ua si tag nrho rau lawv qhov zoo. Cov kev sib txuas sib txuas tau yooj yim yog qhov tseem ceeb interface rau kev sim, kev saib xyuas, thiab kev hloov pauv. Kev sib txuas ntawm cov khoom txav tau yooj yim dua los nrhiav qhov yuam kev hauv qhov txuas dua li qhov kev sib txuas ruaj khov, ua kom yooj yim los hloov cov khoom tsis raug, yog li txhim kho kev tswj xyuas thiab txo cov nqi tu.
3. Optical fiber tau los ze zog rau cov neeg siv terminals. Dab tsi yog qhov tseem ceeb ntawm "fiber rau lub desktop" thiab dab tsi yuav tsum tau them sai sai rau thaum tsim lub kaw lus?
Nyob rau hauv daim ntawv thov ntawm "fiber rau lub desktop" nyob rau hauv kab rov tav subsystems, kev sib raug zoo nrog tooj liab cables yog complementary thiab indispensable. Optical fiber muaj nws qhov tshwj xeeb zoo, xws li kev sib kis ntev, kev sib kis ruaj khov, tsis cuam tshuam los ntawm electromagnetic cuam tshuam, kev txhawb nqa bandwidth siab, thiab tsis muaj electromagnetic to. Cov yam ntxwv no ua rau cov khoom siv fiber ntau ua lub luag haujlwm tsis tuaj yeem hloov tau li tooj liab cable hauv qee qhov chaw tshwj xeeb:
1. Thaum qhov kev ncua deb ntawm cov ntaub ntawv taw tes yog ntau dua 100m, yog tias koj xaiv siv tooj liab cable. Repeaters yuav tsum tau ntxiv los yog cov cuab yeej siv network thiab tsis muaj zog tam sim no yuav tsum tau ntxiv, yog li ua rau cov nqi nce ntxiv thiab muaj peev xwm ua txhaum. Qhov teeb meem no tuaj yeem daws tau yooj yim siv optical fiber.
2. Hauv cov chaw ua haujlwm tshwj xeeb (xws li cov chaw tsim khoom, tsev kho mob, chav tsev khoom siv cua txias, chav siv hluav taws xob, thiab lwm yam) muaj ntau qhov chaw cuam tshuam hluav taws xob. Optical fibers tuaj yeem ua haujlwm ruaj khov hauv cov cheeb tsam no yam tsis muaj kev cuam tshuam los ntawm electromagnetic cuam tshuam.
3. Tsis muaj electromagnetic to nyob rau hauv optical fibers, thiab nws yog ib qho nyuaj heev los xyuas cov teeb liab kis tau nyob rau hauv optical fibers. Nws yog ib qho kev xaiv zoo nyob rau hauv cov chaw uas muaj kev ceev ntiag tug siab (xws li tub rog, R & D, kev tshuaj xyuas, tsoomfwv thiab lwm yam lag luam).
4. Nyob rau hauv ib puag ncig uas yuav tsum tau muaj bandwidth siab, ncav cuag ntau tshaj 1G, optical fiber yog ib qho kev xaiv zoo.
Daim ntawv thov ntawm fiber ntau optical yog maj mam nthuav tawm ntawm lub caj dab lossis chav tsev hauv computer mus rau desktop thiab cov neeg siv hauv tsev, uas txhais tau hais tias ntau thiab ntau tus neeg siv uas tsis nkag siab txog cov yam ntxwv ntawm optical fiber yog pib los rau hauv kev sib cuag nrog optical fiber systems. Yog li ntawd, thaum tsim kho qhov muag fiber ntau txuas system thiab xaiv cov khoom, tam sim no thiab yav tom ntej daim ntawv thov kev xav tau ntawm lub kaw lus yuav tsum tau txiav txim siab tag nrho, thiab cov khoom siv tau zoo thiab cov khoom siv yuav tsum tau siv los pab txhawb kev tu thiab tswj kom ntau li ntau tau, thiab hloov mus rau qhov qub. -hloov cov xwm txheej ntawm qhov chaw thiab cov neeg siv kev xav tau kev txhim kho.
4. Lub FC connector puas tuaj yeem txuas ncaj qha rau SC connector?
Yog lawm, cov no tsuas yog cov kev sib txuas sib txawv rau ob hom kev sib txuas sib txawv.
Yog tias koj xav tau txuas lawv, koj yuav tsum xaiv lub hybrid adapter. Siv FC / SC adapter los txuas FC connectors thiab SC connectors ntawm ob qho tib si. Txoj kev no yuav tsum tau hais tias cov connectors yuav tsum tag nrho cov av tiaj tus. Yog tias koj yuav tsum txuas lub kaum sab xis (APC) txuas, koj yuav tsum siv txoj kev thib ob los tiv thaiv kev puas tsuaj.
Qhov thib ob txoj kev yog siv ib tug hybrid thaj qaum thiab ob qho kev sib txuas adapters. Hybrid patch cords yog cov uas siv ntau hom fiber ntau optic connector ntawm ob qhov kawg. Cov connectors no yuav mus rau qhov chaw koj xav tau txuas. Qhov no tso cai rau koj siv ib qho adapter nyob rau hauv lub thaj vaj huam sib luag los txuas rau lub kaw lus, tab sis ntawm tus nqi ntawm qhov system attenuation pob nyiaj siv. Qhov nce ntawm ib tug connector khub.
5. Kev sib txuas ruaj khov ntawm cov khoom siv kho qhov muag muaj xws li cov khoom siv kho qhov muag fiber ntau splicing thiab thermal fusion splicing. Yog li dab tsi yog cov ntsiab lus xaiv rau cov khoom siv kho qhov muag fiber ntau thiab thermal fusion splicing?
Cov tshuab kho qhov muag fiber ntau splicing, feem ntau hu ua optical fiber txias splicing, hais txog ib qho kev sib txuas ntawm fiber ntau optical uas tsis tas yuav tsum tau kub fusion splicer thiab siv cov cuab yeej splicing yooj yim thiab cov cuab yeej siv tshuab txuas mus tas li txuas ib leeg-core lossis multi-core optical fibers. Feem ntau, thaum splicing optical fibers nrog cov lej me me thiab cov chaw tawg, cov khoom siv sib txuas yuav tsum tau siv tsis yog thermal splicing.
Nyob rau hauv thaum ntxov hnub, mechanical optical fiber splicing thev naus laus zis tau siv ntau hauv engineering kev coj ua xws li kev kho mob xwm txheej ceev thiab kev siv me me hauv lub sijhawm tshwj xeeb. Nyob rau hauv xyoo tas los no, nrog rau kev xa tawm loj ntawm fiber ntau-rau-tus-desktop thiab fiber-to-the-tsev (FTTH), tib neeg tau pom qhov tseem ceeb ntawm cov tshuab fiber ntau splicing raws li ib qho tseem ceeb fiber ntau splicing txoj kev.
Rau fiber-to-the-desktop thiab fiber-to-the-tsev daim ntawv thov uas muaj ntau tus neeg siv thiab cov chaw sib cais, thaum cov neeg siv teev nce mus txog ib theem, kev tsim kho complex, cov neeg ua haujlwm tsim kho thiab fusion splicers tsis tuaj yeem ua tau raws sijhawm. cov kev xav tau ntawm cov neeg siv los qhib cov kev pabcuam. Vim nws txoj haujlwm yooj yim, lub sijhawm luv luv ntawm cov neeg ua haujlwm, thiab cov cuab yeej siv me me, cov khoom siv fiber ntau splicing muab cov txiaj ntsig zoo fiber ntau rau kev xa tawm loj. Piv txwv li, nyob rau hauv qhov chaw siab hauv txoj kev hauv tsev, hauv qhov chaw me me, qhov chaw teeb pom kev zoo tsis txaus thiab cov khoom siv hluav taws xob hauv qhov chaw tsis yooj yim, cov khoom siv kho qhov muag fiber ntau splicing muab kev tsim, kev tsim kho thiab tu cov neeg ua haujlwm nrog kev yooj yim, ua tau zoo, ceev thiab ua haujlwm siab optical fiber. txoj kev splicing.
