Cov neeg siv xav tau
Kev nthuav dav thiab txhim kho: Txuas 40ch DWDM wavelength faib multiplexing cov khoom siv rau 1550nm channel ntawm 8ch CWDM wavelength faib multiplexing cov khoom kom ua tiav kev sib txuas lus channel.
Node xav tau: Cov kab txuas yog 70km ntev, thiab ob lub nras yuav tsum tau ntxiv ntawm 25km thiab 55km.
2. Lub phiaj xwm tsim
Vim muaj qhov txwv ntawm bandwidth, nws tsis tuaj yeem paub qhov nthuav ntawm 40 DWDM cov chaw. Yog li no, Feiyu engineers saws 8ch C27-C34 DWDM wavelength faib multiplexing cov khoom siv kom tau raws li cov neeg siv cov ntawv thov.
Txij li thaum poob ntawm lub nthwv faib cov cuab yeej siv ntau yam sib txuam, OADM thiab tag nrho cov khoom siv fiber ntau yog ≤24dB, kev siv cov amplifiers tuaj yeem ua kom nrov loj rau cov zis ntawm ib qho channel rau 8db, thiaj li ua kom zoo dua txuas cov teeb liab zoo thiab txo kev ua yuam kev.
Ntxiv 1ch OADM ntawm node, rub tawm thiab xa cov cim
