CWDM Ntaus
CWDM yog ib txoj kev siv nyiaj tsawg los ua kom dhau cov fiber ntau uas muaj tam sim no los ntawm kev txo qis cov channel sib nrug ntawm wavelengths. CWDM muaj tus nqi qis dua rau ib qho channel tshaj qhov ntom ntom WDM (DWDM) thiab tsis muaj kev teeb tsa yog qhov tsim nyog. CWDM cov khoom siv kho qhov muag tuaj yeem nce cov bandwidth ntawm cov hluav taws xob fiber ntau uas twb muaj lawm thiab pab txo kev ua kom cov nqaij fiber ntau. CWDM cov khoom siv kho qhov muag muaj xws li 4-channel, 8-channel lossis 16-channel mux / demux modules lossis raws li ib qho ntxiv / poob module.
FOCC 1x2 3 Qhov CWDM
 | 3-chaw nres nkoj CWDM ntaus ntawv yog siv cov passive wavelength faib multiplexing module. Nws yog ib hom wavelength faib multiplexing tshuab raws li TFF (lim zaj duab xis lim). Nws muaj ntau yam ntawm qhov ntau thiab tsawg thiab cov kev xaiv wavelength. Nws muaj peb lub chaw nres nkoj: COM, Hla thiab Reflect. Txoj kev nthwv dej nthwv tau raws li ITU-I G.695 tus qauv. Nws tuaj yeem Mux, Demux lossis ntxiv-poob multiplexing sib txawv lub teeb hauv WDM system. Cov paib, ntxiv rau cov teeb liab sib kis ceev thiab muaj peev xwm sib txuas lus tau siv dav hauv kev sib tham xov tooj cua, xov tooj cua thiab this vis, koom tes network, thaj chaw hauv tsev kawm ntawv thiab lwm cov teb. |

Thov
CWDM pab kiag li lawm siv nyob rau hauv passive wavelength faib multiplexing system module khoom, uas tuaj yeem Mux, Demux lossis ntxiv-poob multiplexing cov cim kho qhov muag sib txawv, ua tau raws li qhov yuav tsum tau muab cov nqi sib txawv ntawm cov xa hluav taws xob rau cov txheej txheem ntawm ib qho kho qhov muag, xws li Ethernet, ATM, POS, SDH, thiab lwm yam, thiab dav siv hauv kev sib tham xov tooj cua, xov tooj cua thiab this vis, chaw koom tes, thaj chaw hauv tsev kawm ntawv thiab lwm cov teb.
