Cov khoom siv CWDM passive wavelength division multiplexing tuaj yeem txuag tau cov peev txheej fiber thiab cov nqi network, daws cov teeb meem ntawm fiber tsis txaus, kev xa ntau yam kev pabcuam pob tshab thiab luv lub sijhawm tsim kho. Xov tooj cua thiab TV 1310/1550CATV TV cov teeb liab tau xa tawm pob tshab, paub txog kev xa tawm ywj pheej ntawm CATV cov kev pabcuam thiab cov kev pabcuam cov ntaub ntawv hauv ib qho fiber optical yam tsis cuam tshuam nrog ib leeg, thiab tuaj yeem tsim cov tes hauj lwm thiab ua lag luam hauv lub sijhawm luv luv.
Vim tias CWDM muaj ntau yam zoo xws li tus nqi qis, siv hluav taws xob tsawg, me me, thiab lwm yam, nws yog qhov kev daws teeb meem kis tau tus nqi qis, ua haujlwm tau zoo.
Tam sim no CWDM tau siv dav hauv kev sib kis hauv nroog. Peb lub tuam txhab tau tsim cov khoom siv CWDM rau G652, G.653, thiab G.655 optical fibers raws li kev thov ntawm kev ua lag luam, uas yog qhov kev xaiv zoo tshaj plaws rau kev loj hlob ntawm nroog.
