1. Qhov twg yog tus nqi ntau dua, CWDM lossis DWDM?
CWDM (Coarse Wave Division Multiplexing) feem ntau yog tus nqi ntau dua li DWDM (Dense Wave Division Multiplexing), tsim nyog rau qhov muaj peev xwm qis dua thiab luv dua. CWDM thev naus laus zis tau siv rau cov cuab yeej siv yooj yim, ua rau nws xaiv tus nqi zoo thaum cov channel siab ceev thiab kev xa mus ntev tsis yog qhov yuav tsum tau ua hauv network.
2. CWDM thiab DWDM puas tuaj yeem koom ua ke hauv tib lub network?
Yog lawm, CWDM (coarse yoj division multiplexing) thiab DWDM (dense wave division multiplexing) tuaj yeem nyob hauv tib lub network. Lawv ua haujlwm ntawm qhov sib txawv wavelength interval scales thiab tuaj yeem ua tau raws li qhov sib txawv ntawm lub peev xwm thiab kev ncua deb ntawm qhov sib txawv ntawm lub network.
3. Dab tsi yog lub luag haujlwm ntawm lub teeb liab modulation ua si hauv WDM systems?
Lub teeb liab modulation nyob rau hauv wavelength division multiplexing (WDM) systems yog ib qho tseem ceeb rau encoding digital cov ntaub ntawv mus rau optical signals, ua kom lawv kis tau ib txhij los ntawm ib tug fiber optic. Nws ua kom cov ntaub ntawv sib kis tau zoo, teeb liab kev ncaj ncees, thiab kev sib raug zoo ntawm cov khoom siv hauv network, pab txhim kho tag nrho cov kev ua tau zoo thiab kev ua haujlwm ntawm WDM tes hauj lwm.
4. CWDM lossis DWDM yog dab tsi?
CWDM tuaj yeem siv rau kev sib txuas lus sab hauv hauv kev lag luam, kev sib txuas hauv cov ntaub ntawv, thiab kev sib txuas ntawm lub hauv paus chaw nres tsheb wireless; DWDM tuaj yeem siv rau kev sib txuas lus hauv lub cev, kev sib txuas lus ntev thoob ntiaj teb, thiab kev sib txuas ntawm cov ntaub ntawv loj.
5. CWDM thiab DWDM tuaj yeem txhim kho kev ua haujlwm ntawm optical network li cas?
Coarse yoj division multiplexing (CWDM) thiab ntom yoj division multiplexing (DWDM) tso cai rau tib lub sijhawm sib kis ntawm ntau cov ntaub ntawv qhia ntawm tib lub fiber ntau kho qhov muag, yog li txhim kho kev ua haujlwm ntawm optical networks. Qhov no ua rau kom tag nrho lub peev xwm ntawm lub network tsis tas yuav tsum tau ntxiv fiber ntau optics.
