Q3: Dab tsi yog hom fiber ntau thaj cables?
A3: Fiber thaj cables tuaj nyob rau hauv ntau hom raws li ntau yam, xws li kis tau tus mob nrug, kis hom thiab cable qauv. Nov yog cov hom tseem ceeb:
1. Kev ncua deb: Fiber thaj cables tuaj yeem muab faib ua ib hom lossis multimode. Tib hom cables (OS2) yog siv rau kev sib txuas lus nyob deb, feem ntau nyob rau hauv cov pob txha caj qaum lossis qhov chaw dav dav. Multimode cables, haum rau luv luv thiab ntxiv kev faib tawm raws li kev ua tau zoo, xws li OM1, OM2, OM3, thiab OM4, yog txhua tus tsim los rau qhov kev ncua deb thiab bandwidth xav tau.
2. Hom kev sib kis: Fiber thaj cables tuaj yeem yog hom AA crossover, qhov kawg ntawm ob qho tib si sib txuas, lossis hom AB ncaj nraim, qhov kawg ib kawg muaj A-hom connector thiab lwm yam muaj B-hom connector. . Qhov kev xaiv ntawm hom kis tau tus mob nyob ntawm qhov kev sib txuas tshwj xeeb ntawm cov khoom siv.
3. Cable Structure: Raws li cov qauv cable, fiber ntau thaj cables tuaj yeem muab faib ua simplex thiab duplex. Simplex cables siv ib qho fiber ntau rau ib-txoj kev cov ntaub ntawv kis tau tus mob thiab feem ntau ua hauj lwm point-to-point sib txuas. Duplex cables, muaj ob fibers, txhawb kev sib txuas lus bidirectional thiab feem ntau siv hauv kev teeb tsa network.

Q5: Dab tsi yog hom txuas polishing rau fiber ntau thaj cables?
A5: Hom polishing siv rau fiber ntau plays lub luag haujlwm tseem ceeb hauv kev ua haujlwm tag nrho ntawm fiber ntau optic system. Peb hom polishing yog feem ntau siv: Lub cev tiv tauj (PC), Ultra Physical Contact (UPC), thiab Angled Physical Contact (APC).
PC: Lub ntsej muag fiber ntau muaj me ntsis cylindrical curvature, tsom rau kev tshem tawm lossis txhim kho qhov sib txawv ntawm huab cua. Vim nws qhov kev ua tau zoo dhau los, PC tsis tuaj yeem ua tau raws li qhov xav tau ntau dua rau kev sib txuas fiber ntau zoo hauv kev lag luam kev sib txuas lus niaj hnub no thiab tau maj mam hloov los ntawm UPC ua tau zoo dua.
UPC: Raws li lub PC lub ntsej muag lub ntsej muag lub ntsej muag, txoj kev txuas ntxiv polishing ua rau qis dua (ORL) lossis qhov cuam tshuam qhov tseem ceeb thiab muab cov cim kev ntseeg siab dua. Nws yog tsuas yog siv rau TV, xov tooj thiab cov ntaub ntawv systems.
APC: Lub ntsej muag fiber ntau yog polished ntawm lub kaum sab xis 8 degree rau kev sib txuas nruj dua thiab cov pa me me. Nws yog siv nyob rau hauv FTTX, PON thiab lwm yam WDM systems.

Q1: Dab tsi yog lub tsho ntawm fiber ntau optic thaj qaum?
A1: Lub tsho ntawm fiber ntau optic thaj qaum yog txheej tiv thaiv rau cov khoom siv kho qhov muag sab hauv, uas muab cov kav ntev thiab kev nyab xeeb hauv ntau qhov chaw. Hom fiber ntau optic thaj qaum tsho muaj xws li:
PVC (riser / OFNR): PVC tsho feem ntau yog siv rau sab hauv tsev. Lawv muab kev tiv thaiv tsim nyog tiv thaiv kev puas tsuaj rau lub cev thiab muaj txiaj ntsig zoo, tab sis lawv tsis haum rau qhov kub thiab txias los yog qhov chaw sab nraum zoov vim tias lawv tso cov pa phem thaum hlawv.
LSZH (Low Smoke Zero Halogen/LSOH): LSZH tsho yog ib puag ncig tus phooj ywg thiab muaj cov nplaim hluav taws zoo, uas tuaj yeem txo cov pa luam yeeb thiab halogens thaum muaj hluav taws kub. Txawm hais tias lawv kim dua li PVC, lawv muaj kev tiv thaiv hluav taws zoo dua, ua rau lawv zoo tagnrho rau kev nyab xeeb hauv tsev xws li cov chaw zov me nyuam, chaw ua haujlwm, thiab cov vaj tsev pej xeem.
OFNP (Plenum): OFNP lub tsho yog ua los ntawm cov khoom siv hluav taws kub siab tshaj plaws thiab yog tsim los siv rau hauv qhov chaw siab xws li lub qhov cua ducts lossis rov qab cua plenum systems. Lawv tiv thaiv kev sib kis ntawm cov nplaim taws thiab txo cov pa taws. Vim rov qab sib raug zoo, OFNP thaj qaum tuaj yeem hloov OFNR cables.
Q2: Dab tsi yog daim ntawv thov ntawm fiber ntau optic cables?
A2: Fiber optic cables tau siv ntau yam kev siv vim tias lawv tuaj yeem xa cov ntaub ntawv hla kev deb ntawm kev kub ceev nrog cov teeb liab tsawg tsawg. Common siv muaj xws li:
Txuas optical modules thiab lwm yam khoom siv kho qhov muag. Ib hom modules siv ib hom kab cords, thaum ntau hom modules tuaj yeem siv cov kab sib txuas sib txuas nyob ntawm cov ntaub ntawv tus nqi.

Q3: Vim li cas fiber optic cable sai npaum li cas ntawm tooj liab cables?
A3: Fiber optic cables sai dua li tooj liab cables vim tias lawv siv cov teeb liab teeb liab (photons) es tsis txhob siv hluav taws xob (electrons), tso cai rau cov ntaub ntawv mus rau ze li ntawm qhov ceev ntawm lub teeb yam tsis muaj kev cuam tshuam los ntawm kev tiv thaiv lossis kev muaj peev xwm; Lawv muaj kev cuam tshuam cov teeb liab tsawg dua nyob rau qhov ntev, tiv thaiv kev cuam tshuam ntawm electromagnetic cuam tshuam, muab cov bandwidth ntau dua rau kev xav tau kev sib txuas lus siab niaj hnub no, thiab zam cov teeb meem crosstalk uas tuaj yeem txo qis kev sib kis tau zoo hauv cov tooj liab cables.
Q4: Cov fiber ntau puas tuaj yeem khoov ib ncig ntawm lub kaum ntse ntse?
A4: Fiber thaj cables feem ntau yuav tsum tsis txhob khoov ntawm cov ces kaum ntse, vim qhov no tuaj yeem ua rau muaj kev puas tsuaj rau cov fibers sab hauv, ua rau lub teeb liab poob lossis tawg. Txawm li cas los xij, nws tau pom zoo kom siv khoov-insensitive fiber ntau thaj cables rau ib puag ncig uas khoov tsis tau. Cov cables no tau tsim tshwj xeeb los tiv thaiv kev khoov nruj dua yam tsis muaj kev cuam tshuam kev ua haujlwm.
ITU-T G.657 cov qauv muaj ntau theem ntawm ib hom fiber ntau thaj cables 'khoov-insensitivity: G.657.A1 fiber ntau thaj cables muaj qhov tsawg kawg nkaus khoov vojvoog ntawm 10 hli, thiab G.657.A2 fiber ntau thaj cables ntawm 7.5 hli . G.657.A2 yog ntau khoov-insensitive thiab haum rau installation uas yuav tsum tau nruj nreem khoov. Nyob ntawm koj cov kev xav tau tshwj xeeb, koj tuaj yeem xaiv tus qauv tsim nyog los xyuas kom meej qhov kev ua tau zoo thiab hloov tau yooj yim rau koj qhov chaw teeb tsa.
Q5: Yuav ua li cas tswj fiber ntau thaj cables?
A5: Kev saib xyuas zoo ntawm fiber ntau thaj cables yog qhov tseem ceeb rau kev ua kom pom kev ua haujlwm zoo, tiv thaiv kev puas tsuaj, thiab txuas ntxiv lawv lub neej. Nov yog qee qhov kev coj ua tseem ceeb los tswj cov fiber ntau thaj cables:
1. Tsis txhob dhau-khoov thiab voj cov fiber ntau thaj cables hauv kev siv, vim qhov no yuav ua rau kom lub teeb pom kev hauv cov txheej txheem sib kis. Lub vojvoog dabtsi yog khoov yuav tsum siab dua lossis sib npaug li 150 mm thaum khoov lossis coiling.
2. Tiv thaiv lub connector ferrule thiab nws endface los ntawm bruising thiab kis kab mob, thiab muab tso rau ntawm lub plua plav cap tam sim ntawd tom qab disassembly.
3. Thaum txuas cov connectors ntawm fiber ntau optic thaj qaum, lawv yuav tsum tau sib xws nrog hom flange (adapter) siv. Piv txwv li, FC / PC-FC / APC thaj qaum yuav tsum muaj ib qho txuas txuas rau FC / PC adapter thaum lwm qhov kawg txuas rau FC / APC adapter.
