Ua tus kws tshaj lij ntawm cov khoom siv cable,IB LUB NTIJ TEBmuab cov khoom siv fiber ntau optical cable tag nrho, suav nrog cov fiber ntau optical ib hom zoo. Raws li lub hauv paus xa xov ntawm cov tes hauj lwm sib txuas lus niaj hnub no, cov fiber ib hom yog siv dav hauv cov kab ke sib txuas lus ntev thiab ceev ceev vim nws cov bandwidth siab, attenuation qis, thiab qhov deb kis tau ntev.
Hauv tsab xov xwm no, peb tshawb nrhiav cov yam ntxwv ntawm wavelength thiab kev sib kis ntawm ib homcov khoom siv fiber ntaulos ntawm qhov kev xav ntawm cov khoom siv, muab cov kev nkag siab zoo rau kev xaiv cov khoom siv thiab kev tsim cov cable.
1. Cov Qauv Tseem Ceeb ntawm Ib Hom Optical Fiber
Ib hom fiber ntau optical muaj ib lub core thiab cladding. Lub refractive index ntawm lub core siab dua li ntawm lub cladding, uas tso cai rau lub teeb kis mus rau hauv tag nrho cov reflection sab hauv lub core. Cov qauv no tsuas yog txhawb nqa ib hom kev kis (hom tseem ceeb), tshem tawm cov modal dispersion thiab txhim kho qhov zoo ntawm kev sib kis.
Feem ntau, lub cheeb ntawm lub hauv paus yog txij li ntau lub micrometers mus txog li 10 μm, thaum lub cheeb ntawm lub cladding yog kwv yees li 125 μm.
2. Qhov Tseem Ceeb ntawm Wavelength
Qhov ntev ntawm lub wavelength ua lub luag haujlwm tseem ceeb hauv kev sib txuas lus fiber ntau. Cov qhov rai xa xov feem ntau siv suav nrog:
O-band (1260–1360 nm)
C-band (1530–1565 nm)
L-band (1565–1625 nm)
Hauv cov kab ntev no, cov fibers optical qhia tau zoo heev rau kev sib kis. Ntawm lawv, C-band muaj qhov tsis tshua muaj zog (qis li kwv yees li 0.2 dB / km), ua rau nws yog lub qhov rais ua haujlwm tseem ceeb rau kev sib txuas lus optical deb, ceev ceev.
3. Cov yam ntxwv ntawm kev xa xov tseem ceeb
Coefficient ntawm kev txo qis:
Tus coefficient attenuation, ntsuas hauv dB/km, yog ib qho tseem ceeb uas siv los ntsuas qhov poob ntawm kev sib kis. Nws feem ntau yog los ntawm kev nqus thiab kev tawg ntawm cov khoom. Hauv C-band, qhov attenuation tuaj yeem qis li ntawm 0.2 dB/km, thaum nws siab dua me ntsis hauv O-band.
Cov fiber ntau hom optical uas ONE WORLD muab yog tsim los ntawm kev siv cov khoom siv huv si thiab cov txheej txheem ruaj khov, ua kom muaj kev ua haujlwm attenuation zoo ib yam li cov qauv txheem rau kev sib kis mus ntev.
Cov yam ntxwv ntawm kev tawg:
Kev tawg paj yog hais txog qhov sib txawv ntawm qhov ceev ntawm lub teeb ntawm ntau qhov wavelengths, uas ua rau lub teeb liab dav dua. Los ntawm kev ua kom zoo dua cov khoom siv thiab kev tsim qauv, cov fibers tuaj yeem tsim nrog cov khoom sib txawv kom tau raws li ntau yam kev sib txuas lus.
Qhov Txiav Tawm Wavelength:
Qhov wavelength txiav tawm yog qhov wavelength tsawg kawg nkaus uas kev sib kis ib hom tuaj yeem tswj tau, feem ntau yog nyob rau hauv qhov ntau ntawm 1260–1300 nm. Hauv qab tus nqi no, cov hom kev txiav txim siab dua tuaj yeem nthuav dav, cuam tshuam rau kev ruaj ntseg ntawm lub teeb liab. ONE WORLD tswj hwm qhov wavelength txiav tawm kom ntseeg tau tias kev ua haujlwm ib hom ruaj khov hauv qhov ntau ntawm kev ua haujlwm teev tseg.
Hom Teb Txoj Kab uas hla (MFD):
Qhov txoj kab uas hla ntawm hom teb piav qhia txog kev faib tawm ntawm lub teeb pom kev zoo hauv lub fiber core thiab cuam tshuam rau kev ua haujlwm ntawm kev sib txuas thiab kev ua haujlwm ntawm kev sib txuas. Muaj ntau yam MFD specifications sib txawv kom ua tau raws li ntau yam kev tsim qauv thiab kev ntim khoom.
4. Kev Txhim Kho Kev Ua Haujlwm ntawm Kev Sib Kis
Kev ua tau zoo ntawm kev xa xov ntawm cov fiber ntau hom optical tuaj yeem txhim kho ntxiv los ntawm kev ua kom cov khoom siv huv thiab cov txheej txheem tsim khoom zoo li MCVD (Modified Chemical Vapor Deposition). Cov kev txhim kho no pab txo qhov kev nqus dej tsis huv thiab cov qauv tsis zoo, ua rau muaj kev txo qis thiab cov yam ntxwv zoo dua.
ONE WORLD pheej ua raws li kev txhim kho kev lag luam thiab ua haujlwm ze nrog cov neeg koom tes txhim khu kev qha los muab cov khoom siv fiber ntau optical ruaj khov thiab zoo.
5. Xaus Lus
Cov yam ntxwv ntawm cov wavelength thiab kev sib kis ntawm cov fiber ntau optical ib hom ncaj qha txiav txim siab qhov ua tau zoo ntawm cov kab ke sib txuas lus optical. Kev nkag siab meej txog cov yam ntxwv tseem ceeb no pab txhim kho kev tsim qauv fiber network thiab ua tau raws li qhov xav tau ntawm kev xa cov ntaub ntawv ceev thiab muaj peev xwm siab.
Ua ib tus khub koom tes hauv kev tsim cov khoom siv cable, ONE WORLD cog lus tias yuav muab cov fiber ntau optical fiber uas ruaj khov thiab txhim khu kev qha los txhawb koj cov haujlwm sib txuas lus. Xav tiv tauj peb kom paub ntau ntxiv txog cov khoom thiab kev txhawb nqa kev siv tshuab.
