Cov xov hluav taws xob fiber ntau hauv dej hiav txwv tau tsim tshwj xeeb rau cov chaw nyob hauv dej hiav txwv, muab kev xa cov ntaub ntawv ruaj khov thiab txhim khu kev qha. Lawv tsis yog tsuas yog siv rau kev sib txuas lus hauv nkoj xwb tab sis kuj siv dav hauv kev sib txuas lus hla dej hiav txwv thiab kev xa cov ntaub ntawv rau cov roj thiab roj av hauv hiav txwv, ua lub luag haujlwm tseem ceeb hauv cov kab ke sib txuas lus hauv dej hiav txwv niaj hnub. Txhawm rau kom ntseeg tau tias muaj kev ruaj khov ntawm kev ua haujlwm hauv hiav txwv, cov xov hluav taws xob fiber ntau hauv dej hiav txwv tau tsim los kom tsis txhob muaj dej, tiv taus siab, tiv taus xeb, muaj zog heev, thiab yoog tau yooj yim.
Feem ntau, cov qauv ntawm cov xov hluav taws xob marine fiber muaj tsawg kawg yog ib lub fiber unit, sheath, txheej armor, thiab lub tsho sab nraud. Rau cov qauv tsim tshwj xeeb lossis daim ntawv thov, cov xov hluav taws xob marine fiber yuav tshem tawm txheej armor thiab hloov chaw siv cov ntaub ntawv hnav-resistant ntau dua lossis cov tsho sab nraud tshwj xeeb. Tsis tas li ntawd, txhawm rau hloov kho rau ntau qhov chaw sib txawv, cov xov hluav taws xob marine fiber kuj tseem yuav suav nrog cov txheej tiv taus hluav taws, cov tswv cuab hauv nruab nrab / txhawb nqa, thiab cov ntsiab lus ntxiv thaiv dej.
(1) Chav Fiber Optical
Lub tshuab fiber yog lub hauv paus tseem ceeb ntawm cov xov hlau fiber ntau hauv dej hiav txwv, uas muaj ib lossis ntau lub fiber ntau.
Cov fiber optic yog lub plawv ntawm lub cable, feem ntau muaj lub plawv, cladding, thiab txheej, nrog rau lub voj voog concentric. Lub plawv, ua los ntawm high-purity silica, yog lub luag haujlwm rau kev xa cov teeb liab optical. Lub cladding, kuj ua los ntawm high-purity silica, nyob ib puag ncig lub plawv, muab ib qho chaw reflective thiab optical cais, nrog rau kev tiv thaiv mechanical. Lub txheej, txheej sab nraud tshaj plaws ntawm cov fiber, yog ua los ntawm cov ntaub ntawv xws li acrylate, silicone roj hmab, thiab nylon, tiv thaiv cov fiber los ntawm noo noo thiab kev puas tsuaj mechanical.
Feem ntau cov fiber ntau yog muab faib ua cov fiber ib hom (piv txwv li, G.655, G652D) thiab ntau hom fiber (piv txwv li, OM1-OM4), nrog rau cov yam ntxwv sib txawv ntawm kev sib kis. Cov yam ntxwv tseem ceeb ntawm kev sib kis suav nrog qhov siab tshaj plaws attenuation, qhov tsawg kawg nkaus bandwidth, qhov ntsuas refractive zoo, qhov qhib lej, thiab qhov siab tshaj plaws dispersion coefficient, uas txiav txim siab qhov ua tau zoo thiab qhov deb ntawm kev sib kis teeb liab.
Cov fibers raug puag ncig los ntawm cov raj buffer xoob lossis nruj kom txo qhov cuam tshuam ntawm cov fibers thiab cov teebmeem sab nraud. Kev tsim qauv ntawm lub fiber unit ua kom muaj kev xa cov ntaub ntawv zoo, ua rau nws yog qhov tseem ceeb tshaj plaws thiab tseem ceeb tshaj plaws ntawm cov cables fiber optical marine.
(2) Lub hnab tshos
Lub plhaub fiber yog ib qho tseem ceeb ntawm cov xov hlau, tiv thaiv cov fibers optical. Raws li cov qauv, nws tuaj yeem muab faib ua cov raj buffer nruj thiab cov raj buffer xoob.
Cov raj buffer nruj feem ntau yog ua los ntawm cov ntaub ntawv xws li polypropylene resin (PP), polyvinyl chloride (PVC), thiab halogen-free flame-retardant polyethylene (HFFR PE). Cov raj buffer nruj no lo rau ntawm qhov chaw ntawm cov fiber, tsis muaj qhov sib txawv loj, uas txo qhov kev txav ntawm cov fiber. Qhov kev npog nruj no muab kev tiv thaiv ncaj qha rau cov fiber, tiv thaiv cov dej noo nkag thiab muab lub zog siab thiab tiv taus kev cuam tshuam sab nraud.
Cov raj xa dej tsis xoob feem ntau yog ua los ntawm cov modulus siabPBTyas, puv nrog cov gel thaiv dej kom muab kev nplij siab thiab kev tiv thaiv. Cov raj buffer xoob muaj kev ywj pheej zoo heev thiab tiv taus qhov siab sab nraud. Cov gel thaiv dej tso cai rau cov fibers txav mus los hauv lub raj, pab txhawb kev rho tawm thiab kev saib xyuas fiber. Nws kuj tseem muab kev tiv thaiv ntxiv rau kev puas tsuaj thiab dej noo nkag, ua kom ntseeg tau tias lub cable ruaj khov thiab kev nyab xeeb hauv qhov chaw noo noo lossis hauv qab dej.
(3) Txheej Armor
Cov txheej tiv thaiv no nyob sab hauv lub tsho sab nraud thiab muab kev tiv thaiv ntxiv, tiv thaiv kev puas tsuaj rau cov xov hlau fiber ntau hauv dej hiav txwv. Cov txheej tiv thaiv feem ntau yog ua los ntawm cov hlau galvanized steel braid (GSWB). Cov qauv braided npog cov xov hlau nrog cov hlau galvanized, feem ntau nrog tus nqi npog tsis pub tsawg dua 80%. Cov qauv tiv thaiv muaj kev tiv thaiv tshuab siab heev thiab lub zog tensile, thaum cov qauv braided ua kom muaj kev ywj pheej thiab lub vojvoog khoov me dua (lub vojvoog khoov dynamic rau cov xov hlau fiber ntau hauv dej hiav txwv yog 20D). Qhov no ua rau nws tsim nyog rau cov ntawv thov uas xav tau kev txav mus los lossis khoov ntau zaus. Tsis tas li ntawd, cov khoom siv hlau galvanized muab kev tiv thaiv xeb ntxiv, ua rau nws zoo tagnrho rau kev siv hauv qhov chaw noo noo lossis ntsev tsuag.
(4) Lub tsho sab nraud
Lub tsho sab nraud yog txheej tiv thaiv ncaj qha ntawm cov xov hlau fiber ntau hauv dej hiav txwv, tsim los kom tiv taus lub hnub ci, nag, dej hiav txwv yaig, kev puas tsuaj rau lub cev, kev cuam tshuam lub cev, thiab hluav taws xob UV. Lub tsho sab nraud feem ntau yog ua los ntawm cov ntaub ntawv tiv taus ib puag ncig xws li polyvinyl chloride (PVC) thiab cov pa luam yeeb tsawg xoom-halogen (LSZH) polyolefin, muab kev tiv thaiv UV zoo heev, tiv thaiv huab cua, tiv thaiv tshuaj lom neeg, thiab tiv thaiv hluav taws. Qhov no ua kom lub cable tseem ruaj khov thiab txhim khu kev qha nyob rau hauv cov xwm txheej marine hnyav. Vim yog kev nyab xeeb, feem ntau cov marine optical fiber cables tam sim no siv cov ntaub ntawv LSZH, xws li LSZH-SHF1, LSZH-SHF2, thiab LSZH-SHF2 MUD. Cov ntaub ntawv LSZH tsim cov pa luam yeeb tsawg heev thiab tsis muaj halogens (fluorine, chlorine, bromine, thiab lwm yam), zam kev tso tawm cov pa phem thaum lub sijhawm combustion. Ntawm cov no, LSZH-SHF1 yog qhov siv ntau tshaj plaws.
(5) Txheej Tiv Thaiv Hluav Taws
Hauv cov cheeb tsam tseem ceeb, txhawm rau kom ntseeg tau tias kev sib txuas lus txuas ntxiv thiab kev ntseeg tau ntawm cov kab ke sib txuas lus (piv txwv li, rau cov tswb hluav taws, teeb pom kev zoo, thiab kev sib txuas lus thaum muaj xwm txheej ceev), qee cov xov hlau fiber ntau hauv dej hiav txwv muaj cov txheej tiv taus hluav taws. Cov xov hlau buffer tube xoob feem ntau xav tau ntxiv cov kab xev mica los txhim kho kev tiv taus hluav taws. Cov xov hlau tiv taus hluav taws tuaj yeem tswj tau kev sib txuas lus rau ib lub sijhawm thaum muaj hluav taws, uas yog qhov tseem ceeb rau kev nyab xeeb ntawm lub nkoj.
(6) Txhawb Cov Tswv Cuab
Txhawm rau txhim kho lub zog kho tshuab ntawm cov xov hlau fiber ntau hauv dej hiav txwv, cov tswv cuab txhawb nqa hauv nruab nrab xws li cov xov hlau phosphated lossis cov yas fiber-reinforced (FRP) raug ntxiv. Cov no ua rau lub cable muaj zog thiab tiv taus tensile, ua kom ruaj khov thaum lub sijhawm teeb tsa thiab siv. Tsis tas li ntawd, cov khoom siv txhawb nqa xws li xov aramid tuaj yeem ntxiv los txhim kho lub cable lub zog thiab tiv taus tshuaj lom neeg xeb.
(7) Kev Txhim Kho Cov Qauv
Nrog kev nce qib ntawm thev naus laus zis, cov qauv thiab cov ntaub ntawv ntawm cov xov hlau fiber ntau hauv dej hiav txwv tau hloov pauv tas li. Piv txwv li, cov xov hlau xoob xoob uas qhuav tag nrho tshem tawm cov gel thaiv dej ib txwm muaj thiab siv cov ntaub ntawv thaiv dej qhuav hauv ob qho tib si cov raj xoob thiab cov tub ntxhais cable, muab cov txiaj ntsig ib puag ncig, qhov hnyav sib dua, thiab cov txiaj ntsig tsis muaj gel. Lwm qhov piv txwv yog kev siv cov thermoplastic polyurethane elastomer (TPU) ua cov khoom siv sab nraud, uas muab ntau qhov kub thiab txias, tiv taus roj, tiv taus kua qaub, tiv taus alkali, qhov hnyav sib dua, thiab qhov chaw me dua. Cov kev tsim kho tshiab no qhia txog kev txhim kho tas li hauv kev tsim cov xov hlau fiber ntau hauv dej hiav txwv.
(8) Kev Txheeb Xyuas
Kev tsim qauv ntawm cov xov hlau fiber ntau hauv dej hiav txwv suav nrog cov kev xav tau tshwj xeeb ntawm cov dej hiav txwv, suav nrog kev tiv thaiv dej, kev tiv thaiv siab, kev tiv thaiv corrosion, thiab lub zog kho tshuab. Kev ua haujlwm siab thiab kev ntseeg tau ntawm cov xov hlau fiber ntau hauv dej hiav txwv ua rau lawv yog qhov tseem ceeb ntawm cov kab ke sib txuas lus hauv dej hiav txwv niaj hnub. Raws li thev naus laus zis hauv dej hiav txwv nce qib, cov qauv thiab cov ntaub ntawv ntawm cov xov hlau fiber ntau hauv dej hiav txwv txuas ntxiv hloov pauv kom tau raws li qhov xav tau ntawm kev tshawb nrhiav dej hiav txwv tob dua thiab kev xav tau kev sib txuas lus nyuaj dua.
