一.WDM tshuab muaj cov yam ntxwv hauv qab no:
Muaj peev xwm loj
Cov bandwidth tuaj yeem kis tau los ntawm cov fiber ntau zoo tib yam tam sim no siv dav heev, tab sis nws qhov kev siv tus nqi tseem tsawg heev. SivDWDM technologytuaj yeem ua kom muaj peev xwm kis tau tus mob fiber ntau los ntawm ob peb zaug, kaum ob lub sijhawm, lossis ntau pua zaus piv nrog lub peev xwm sib kis ntawm ib nthwv dej ntev.
2 "pob tshab" kis ntawm cov ntaub ntawv
Vim tias DWDM system yog rov siv dua thiab rov siv dua raws li qhov sib txawv ntawm lub teeb wavelength, nws tsis muaj dab tsi ua rau tus nqi thiab hluav taws xob hloov pauv txoj kev teeb liab, uas yog, cov ntaub ntawv ntawm cov ntaub ntawv yog "pob tshab". Xws li ATM, IP lossis cov cim qhia uas yuav tshwm sim yav tom ntej. Lub nthwv dej duplication ua tiav cov pob tshab sib kis. Rau "kev lag luam" txheej teeb liab, txhua qhov kev kho qhov muag yoj ntev channel hauv nthwv dej duplication system zoo li "virtual" fiber.
3.High degree ntawm network yooj, kev lag luam thiab kev ntseeg tau
Hom tshiab ntawm kev sib txuas lus network tsim los ntawm WDM thev naus laus zis tau yooj yim heev dua li cov qauv network tsim los ntawm cov hluav taws xob ib txwm muaj, thiab qib network tau meej. Lub sijhawm teem sijhawm ntawm ntau lub lag luam tsuas yog yuav tsum tau kho lub wavelength ntawm cov teeb liab sib thooj kom ua tiav. Vim qhov yooj yim network qauv, meej hierarchy, thiab yooj yim ua lag luam teem sij hawm, qhov yooj, kev lag luam thiab kev ntseeg siab ntawm lub network coj los ntawm nws yog pom tseeb.
