Coarse WDM nthuav cov haujlwm
XYT-CWDM (Coarse Wavelength Division Multiplexing) sparse wavelength division multiplexing system, tseem hu ua coarse wavelength faib multiplexing system raws li kev lag luam thiab cov tswv yim luv luv ntawm WDM xa cov kab ke, IP cov ntaub ntawv pabcuam nrog rau txoj kev loj hlob sai ntawm Is Taws Nem, ua rau kev xa xov kab bandwidth thov kom nce ntxiv. Txawm hais tias DWDM (Dense Wavelength Division Multiplexing) thev naus laus zis los ua txoj hauv kev zoo tshaj los daws cov kab bandwidth nthuav dav, tab sis dhau CWDM DWDM thev naus laus zis muaj qhov zoo ntawm cov nqi system, versatility thiab maintainability yam. Nyob rau hauv MAN thov nce ntxiv tau lees paub thiab muaj tswv yim. Network bandwidth bottlenecks maj mam hloov mus rau tus txiv neej, MAN lub tsev tau dhau los ua qhov kub tam sim no kev tsim kho network. Vim hais tias coarse wavelength division multiplexing system (CWDM) thev naus laus zis nrog nws qhov tshwj xeeb zoo dua thiab muaj kev saib xyuas ntau ntxiv hauv kev siv cov xov hlau.
Coarse wavelength division multiplexing system (CWDM) optical fiber tuaj yeem txuag tau nyiaj txiag thiab kev siv network, uas daws cov teeb meem fiber ntau thiab multiservice pob tshab kis tau ntawm ob qhov teeb meem, feem ntau yog siv hauv metro kev sib sau ua ke thiab nkag mus txheej, thiab nyob rau lub sijhawm luv kev tsim kho ntawm lub network thiab coj ua lag luam. Tam sim no CWDM kis Tus Neeg tau txais ntau ntawm cov ntawv thov.
Daim ntaub ntawv raug:
Nta:
1.Advanced 3R (rov ua dua, rov kho thiab rov ua dua tshiab) thev naus laus zis los xyuas kom lub teeb liab xa mus ntev.
