Lub fiber ntau tsis muaj dab tsi ntau tshaj li ib cov plaub hau - daim nyias nyias ntawm cov ntaub ntawv hla dej hiav txwv muaj ntxhi lus ntxhi. Tig cov khoom siv raw rau hauv qhov no yuav luag- phau ntawv qhia txog yog tus tswv - precision kev lag luam. Ntawm no yog ib kauj ruam {- ntawm - theem mus kev "los ntawm cov xuab zeb mus rau teeb liab."
-------------------------------------------------
1. Cov Khoom Siv Raw: "Muaj vajtrapecture" iav xuab zeb
• Cov pub - Tshuag yog high- purity silicon dioxide (sillic impurities khaws cia hauv qab ib feem pua.
• Me me ntawm Germanium tetrachloride (gecl₄) lossis phosphorus oxychloride (pocl₃) yog tom qab ntawd cov fluorine index {}} Qhov no tsim lub teeb core / clad.
-------------------------------------------------
2. Ua tus Preformle: Peb txoj kev loj
A. Hloov cov tshuaj vapor tso cai (MCVD) - feem ntau rau kev sib tham fiber ntau
- 1-2 m Silica Raj rotates rotates rotates nyob rau hauv ib khob - Ua haujlwm Tshuab Dhos thaum Sicl₄, Gecl 11 thiab O₂ ntws los ntawm nws.
- Ib qho oxy - hydrogen nplaim taug kev rov qab mus, oxidising cov kab ntawv rov qab thiab cov tshuaj pleev "uas tso rau hauv phab ntsa sab hauv.
- Txheej tom qab txheej (≈100-500) tsim tawm, thawj cladding, ces tus tub ntxhais nrog maj ntau dua geo₂.
- Thaum rho tawm tau ua tiav lub raj yog vau rau ntawm {{} -}} Performance index profile ntawm kawg fiber ntau.
B. Sab Nraum Vapor Deposition (OVD) & Vapor -}}}}-}} poob fiber
- Soots hais yog nplaim- hydrolysed thiab tso rau sab nraud (ovd) lossis kawg} ntsej muag (vad) ntawm ib qho kev tig ntaus nkauj.
- Cov ntxig ntxeem ntxig yog lub cev qhuav dej nyob hauv Clj, ces sintered rau hauv cov iav pob tshab.
- Lub Central pas nrig raug tshem tawm, tawm ntawm lub tog raj kheej khoom uas nws cov txheej txheej sab nraud ua cladding thiab puab txheej txheej txheem.
C. Ntshav {- ushing itche ™ ™ ™ ™ ™ ™ ™ ™ ™ ™ ™ ™ ™ ™ ™ ™ ™ ™ ™ ™ ™ activ activ ® CVD) - High Precision rau Tshwj Xeeb Fiber
- Lub microwave ntshav sab hauv lub raj tso cai rau kev faib tawm ntawm cov ntsuas kub qis dua thiab ua kom muaj txiaj ntsig zoo rau kev tsim tawm lossis dispersion {0} {{lawb tsim.
-------------------------------------------------
3. Preform luag
• Tus pas av yog cov hauv av yog qhov zoo tshaj plaws tig thiab tshuaj xyuas rau npuas, streaks lossis kev ntxhov siab birefringence.
• Ib lub tsho "lub tsho" ntawm cov ntshiab silica yuav tau pw dhau ntawm cov tub ntxhais / clad sib dhos kom ncav cuag lub taub kawg (feem ntau 20-40 mm).
• Ob qho tag nrho yog nplaim -} polished; Txhua qhov chaw nyob sab nraud yuav propagate rau hauv kilometers ntawm fiber ntau.
-------------------------------------------------
4. Fiber Teeb: Los ntawm 30 hli rau 0.125 hli nyob rau hauv ib lub caij nplooj zeeg
1. Qhov ua tau zoo dua rau hauv graphite tiv thaiv rauv ntawm ≈2 100 degree- li saum toj muag taw tes ntawm silica.
2. Ib qho qauv ntawm molten iav poob, sib haum xov zoo; Ib lub sensor ntsuas nws txoj kab uas hla1 000} lub sij hawm ib ob.
3. Kaw - voj nro thiab ceev tswj (10-30 ms⁻¹) khaws cov taub uas hla mus rau ± 0.1 μm kev thev taus.
4. Nyob rau yoov cov iav liab qab tau txais ob lub tsho tiv thaiv:
- Qhov tseem ceeb: lub UV mos - kho tau acrylate uas cushions micro {{1} bends.
- Thib ob: ib qho nyuaj rau kev ua haujlwm lossis polyimide uas tiv thaiv puas.
5. Lub siab - ceev spool cua 50 - {{} km ntawm fiber ntau rau kev rov ua dua tshiab.
-------------------------------------------------
5. Hauv -} kab kuaj
• Cov Ntawv Pov Thawj Ua Ntawv Pov Thawj: Txhua 'meter' rub tawm rau ≈700 kpsi (≈0.7 Gn M⁻²) kom lav tau ntau dua lossis sib npaug rau 1% hom muaj peev xwm.
• Kho qhov cheb: rov qab {{-} Scatter (OTDr) thiab spectral attuumess tsawg dua lossis sib npaug rau 0.17 db km⁻¹ poob ntawm 1550 nm.
• Cov scan scan: Cov tub ntxhais kawm ntawv / clad cov sharadding, cladding, clog} kev sib ncig thiab txheej diam uas nkag mus rau txhua tus bobbin.
-------------------------------------------------
6. Kev sib txuas: Armoring lub khob plaub hau
• 2-432 Cov xim muaj kob tau tso ib ncig ntawm lub tswv yim nruab nrab (FRP lossis hlau).
• Dej - blocking yarns, qhuav gels thiab / lossis thixotropic filling teb kom ya raws.
• Cov tshuaj tua riam, MDPE rau sab hauv tsev, stainless micro - cov raj rau opgw, lossis stainless hlau + lossis stainless hlau + HDPE rau kev siv nkoj hauv nkoj.
• Cov khoom hluav taws xob tsawg kawg muaj kev ntsuas hluav taws xob suav nrog kev sib cais hluav taws xob muaj kev sib cais, cov chromatic dispersion thiab splification {{1} poob cov txheeb cais.
-------------------------------------------------
7. Zoo & Nyob Li
• ISO 9001/14001 thiab Telcordia Gr-20 kav txhua tsob nroj.
- Khib nyiab pov tseg thiab sio₂ nplua yog txhuam thiab rov ua dua tshiab.
- Zog siv rau cov fiber ntau - km tau poob 40% txij li xyoo 2010 los ntawm kev kho kom muaj hluav taws kub thiab coj Uv kho.
• Niaj hnub no cov fiber ntau muaj 20-30% siv lub khob thiab nws tus kheej 100% siv dua tshiab.
