Cov las las las voos siv tau ua cov dhia los ntawm cov cuab yeej siv rau kev sib txuas fiber ntau optic cabling. Muaj cov tuab tiv thaiv txheej txheem, uas feem ntau siv hauv kev sib txuas ntawm lub tshuab xa hluav taws xob thiab lub npov davhlau ya nyob twg, thiab siv rau qee qhov chaw xws li kev sib txuas lus fiber ntau, kev sib txuas lus fiber ntau, cov phiaj xwm xa xov hluav taws xob, thiab cov xov xwm hauv cheeb tsam. Cov.
qauv
Optical fiber jumper (tseem hu ua optical fiber txuas) txhais tau hais tias ob qho kawg ntawm qhov kho qhov muag cable tau nruab nrog txuas txuas kom paub cov kev sib txuas ntawm cov kab nrig kho qhov muag; ib kawg nrog tus ntsaws hu ua pigtail. Optical Fiber Patch Qaum / Cable zoo ib yam li coaxial cable, tsuas yog tsis muaj cov mesh tiv thaiv txheej txheej. Hauv plawv yog daim iav tseem ceeb uas los ntawm kev sib nraus. Hauv cov roj carbon fiber ntau, qhov taub ntawm qhov tseem ceeb yog 50μm ~ 65μm, ntxig sib npaug nrog tuab ntawm tib neeg cov plaub hau. Ib qho-hom fiber ntau tub ntxhais muaj qhov taub ntawm 8 μm rau 10 μm. Qhov tseem ceeb yog ntim los ntawm lub hnab ntawv iav nrog qis dua qhov ntsuas qhov ua tau zoo tshaj qhov tseem ceeb los khaws cov optical fiber hauv qhov tseem ceeb. Ntawm sab nraud yog lub tsho nyias nyias yas los tiv thaiv lub hnab ntawv.
Kev faib tawm thiab kev soj ntsuam ntawm cov kab hluavtaws fiber ntau optic cords muaj raws li hauv qab no
Cov kab hluav taws xob kho qhov muag (tseem hu ua cov kab hluav taws xob kho qhov muag), uas yog, cov hlua hluav taws xob fiber txuas txuas nrog cov qauv kho qhov muag, kuj muaj ntau yam, thiab lawv siv tsis tau ob leeg. SFP module txuas nrog LC fiber txuas, thiab GBIC txuas nrog rau SC fiber txuas. Cov hauv qab no yog cov lus qhia ntxaws ntxaws ntawm ob peb lub tshuab hluav taws xob feem ntau hauv cov tshuab network:
①FC-hom fiber ntau cov jumper: Sab nraud txhim kho txoj hauv kev yog lub tes tsho hlau, thiab hom fastening yog turnbuckle. Feem ntau siv ntawm ODF sab (feem ntau siv rau ntawm tus ncej)
②SC hom optical fiber ntau jumper: qhov txuas rau txuas lub GBIC optical module, nws lub plhaub yog cov duab plaub, thiab txoj kev ua kom ceev nrawm yog plug-in latch hom, tsis muaj kev sib hloov. (Feem ntau siv rau ntawm cov keyboards router)
ST hom optical fiber jumper: feem ntau siv nyob rau hauv optical fiber faib ncej, lub plhaub yog puag ncig, thiab cov cuab yeej fastening yog turnbuckle. (Rau 10Base-F kev twb kev txuas, lub txuas yog feem ntau ST hom. Feem ntau siv nyob rau hauv optical fiber faib ncej)
④LC hom optical fiber jumper: lub tshuab txuas rau txuas SFP module, nws yog tsim los ntawm kev lag luam yooj yim ua haujlwm (modular jack) (RJ) latch mechanism. (Cov Routers feem ntau siv)

Thab kab lus nyob rau daim ntawv thov ntu lus no
Optical fiber jumper cov khoom siv dav siv hauv: chav sib txuas lus, fiber ntau rau hauv tsev, thaj chaw hauv cheeb tsam network, fiber ntau lub vev xaib fiber ntau, kev sib txuas lus fiber ntau, fiber ntau qhov txuas kis, cov khoom siv hluav taws xob tiv thaiv kev tiv thaiv kev npaj, thiab lwm yam. , kev sib txuas lus hauv xov tooj, khoos phis tawj fiber ntau kho qhov muag thiab cov cuab yeej ntsuas kho qhov muag. Qhov kev qhia txog feem ntau yog siv ntau qhov.
1. Kev sib txuas lus fiber ntau
2. Optical fiber access network
3. Optical fiber ntaub ntawv xa mus
4. Cov roj carbon fiber CATV
5. Lub Zos Hauv Cheeb Tsam Network (LAN)

Siv xim
Cov transceiver wavelengths ntawm qhov kho qhov muag ntawm ob qho kawg ntawm lub fiber ntau tus jumper yuav tsum zoo ib yam, uas yog hais, ob hnub xaus ntawm lub fiber yuav tsum yog cov qauv optical ntawm tib lub yoj yoj. Txoj kev yooj yim kom paub qhov txawv yog tias cov xim ntawm cov tsom iav kho qhov muag yuav tsum zoo ib yam. Feem ntau, luv-wave optical modules siv multimode fibers (txiv kab ntxwv fibers), thiab ntev mus yoj optical module siv ib hom fiber ntau (cov xim daj) kom ntseeg tau qhov tseeb ntawm cov ntaub ntawv xa mus.
Tsis txhob dhau-khoov thiab ntxees lub fiber ntau kho qhov muag thaum siv, vim tias qhov no yuav ua rau kom muaj qhov pom ntawm lub teeb thaum xa tawm.
Tom qab siv cov roj hmab fiber ntau, nco ntsoov siv cov ntaub npog tiv thaiv los tiv thaiv cov kab hlau txuas. Cov hmoov av thiab cov roj yuav ua rau cov kev coj hauv lub fiber ntau.
Yog hais tias tus kav hlau txuas lub qias neeg tau qias neeg, koj tuaj yeem ntxuav nws nrog paj rwb pas nqus dej hauv cawv, txwv tsis pub nws yuav cuam tshuam rau kev sib txuas lus zoo.
1. Lub ntsej muag ceramic thiab lub ntsej muag kawg ntawm lub ntsej muag fiber ntau yuav tsum tau so kom huv nrog cawv thiab nqus dej paj rwb ua ntej siv.
2. Qhov tsawg kawg nkaus khoov rau ntawm txoj kab hluav taws xob tsis tsawg tshaj 150 hli thaum siv.
3. Tiv thaiv qhov txhuam thiab lub ntsej muag kawg ntawm lub taub hau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau plhaw thiab paug. Ua lub ntsej muag plua plav kom raws sijhawm tom qab kev rhuav tshem.
4. Tsis txhob saib ncaj qha rau lub ntsej muag thaum kawg ntawm lub fiber ntau thaum lub teeb liab laser kis tau tus mob.
5. Thaum muaj kev puas tsuaj los ntawm tib neeg tsim lossis lwm yam quab yuam majeure, lub tshuab puas fiber ntau yuav tsum tau hloov lub sijhawm.
6. Nyeem phau ntawv kom zoo zoo ua ntej kev teeb tsa, thiab nruab thiab debug raws li cov lus qhia ntawm cov khw lossis cov kws tsim khoom.
7. Kev ntsuas qhov tsis zoo nyob rau hauv cov kab hluav taws xob fiber ntau lossis cov kab ke yuav ntsuas ib qho los ntawm kev siv cov txheej txheem daws teeb meem. Thaum kuaj pom lossis daws teeb meem jumper kev ua yuam kev, koj tuaj yeem ua qhov kev ntsuas txuas ntxiv txuas ntxiv ua ntej, feem ntau koj tuaj yeem siv lub tshuab hluav taws xob laser pom kom txiav txim rau tag nrho cov kab ntsig kho qhov muag. Los yog txuas ntxiv siv ib qho precision fiber ntau tso ua tsis pom kev poob rov qab tester sim nws ntau yam ntsuas. Yog tias qhov ntsuas yog nyob hauv qhov tsim nyog, tus jumper qhia tau zoo li qub, txwv tsis pub nws tsis tsim nyog.
Xaiv phau ntawv qhia
Cov fiber ntau cov las qij tau muab faib ua peb hom raws li hom kev txiav: ST-ST, SC-SC, ST-SC. Raws li hom fiber ntau, muaj ob hom fiber ntau hom thiab ntau hom fiber ntau. Lub jumper ntev cov lus qhia tshwj xeeb yog 0.5m, 1m, 2m, 3m, 5m, 10m, thiab lwm yam. Raws li cov xov tooj ntawm cov xov sheath, nws tuaj yeem faib ua hom, zoo li nplaim hluavtaws-yam, hom tsis muaj pa luam yeeb halogen tsis pub ( LZSH), muaj hluav taws kub qis halogen-tsis muaj nplaim taws-rov ua dua hom, thiab lwm yam.
Raws li kev ntsuam xyuas hluav taws ntawm lub tsev thiab cov hluav taws tiv thaiv yuav tsum tau ntawm cov ntaub ntawv, cov kab hluav taws xob sib xyaw ua ke yuav tsum ntsuas kev coj ua. Thaum tso cov xaim hluav taws xob lossis cov hlua hluav taws xob hauv cov qhov chaw ua haujlwm thiab lub tsev txuas, cov nplaim hluav taws xob thiab cov xov tooj hluav taws xob yuav tsum tau siv; nyob rau hauv cov chaw pej xeem loj, nplaim taws rov zoo li qub, muaj pa taws, thiab muaj cov yeeb yaj kiab uas tsis tshua muaj roj lossis hluav taws xob uas siv hluav taws xob; Cov chav nyob ib sab los yog chav siv tes ua khoom siv hluav taws xob thaiv cov nplaim hluav taws yuav tsum siv.
