Nkag siab txog lub wavelengths ntawm 850nm, 1310NM thiab 1550nm hauv Optical Fiber
Lub teeb txhais tau los ntawm nws wavelength, thiab hauv kev sib txuas lus fiber ntau, lub teeb siv yog nyob rau hauv infrared cheeb tsam yog ntau dua qhov pom kev. Hauv kev sib txuas lus siv kho qhov muag fiber ntau, lub wavelength raug 800 txog 1600nm, thiab feem ntau siv wavelengths yog 850nm, 1310Nm thiab 1550nm.
Cov Duab Qhov:
Thaum fluxight xaiv cov wavelength, nws tsuas yog txiav txim siab fiber ntau poob thiab tawg. Lub hom phiaj yog txhawm rau kis cov ntaub ntawv tshaj plaws nrog tsawg kawg fiber ntau ploj dhau qhov deb tshaj plaws. Lub sijhawm poob ntawm cov teeb liab muaj zog thaum lub sijhawm sib kis thaum muaj kev ua raws. Qhov kev ua kom muaj feem cuam tshuam txog qhov ntev ntawm cov nthwv dej, lub ntev dua cov nthwv dej, qhov kev ua kom me me. Lub teeb siv nyob rau hauv cov fiber ntau muaj ntev ntev ntev ntev nyob rau hauv 850, 1310, 1550nm, yog li kev ua kom muaj fiber tsawg, uas kuj ua rau tsis muaj fiber ntau poob. Thiab no peb wavelengths muaj yuav luag yuav luag tej qhov nqus, uas haum rau kis tau tus kab mob kho qhov muag tau.
Cov Duab Qhov:
Hauv kev sib txuas lus siv kho qhov muag fiber ntau, cov tshuaj fiber ntau tuaj yeem faib ua ib hom thiab ntau hom. Lub cheeb tsam 850nm wavelength Ract yog feem ntau yog ntau hom kho qhov muag kev sib txuas lus, 1550nm yog ib hom-hom, thiab 1310nm muaj ob hom hom thiab ntau hom. Xa mus rau ITU-T, lub hom phiaj ntawm 1310NM raug pom zoo kom ua ≤0.4db / km, thiab lub etenuation ntawm 1550nm / km. Thiab poob ntawm 850nm yog 2.5db / KM. Fiber ntau tsawg dua tsawg dua li cov nthwv dej nce. Qhov chaw yoj ntawm 1550 nm nyob ib ncig ntawm C-Band (1525-1565nm) feem ntau txhais tau tias kev ua tiav ntawm Quartz fiber yog qhov me tshaj plaws ntawm nthwv dej no.
Beijing Rofoeltronics Co., Ltd. Sib Koom Tes Ua Si " Peb lub tuam txhab feem ntau yog koom nrog kev tshawb fawb ywj pheej thiab tsim qauv, thiab muab cov kev pabcuam tsim kho tshiab, thiab cov kws tshawb fawb txog kev lag luam thiab cov kws tshawb nrhiav kev lag luam. Tom qab xyoo ntawm kev ywj pheej tshiab, nws tau tsim cov khoom nplua nuj thiab zoo nkauj, hluav taws xob siv hauv nroog, hluav taws xob, kev kawm, kev kho mob thiab lwm yam kev lag luam.
