Kodi CWDM ndi chiyani?

-Mu kulumikizana kwa fiber-optic, wavelength-division multiplexing (WDM) ndi ukadaulo womwe umachulukitsa zizindikiro zingapo zonyamula kuwala pa ulusi umodzi wowala pogwiritsa ntchito mafunde osiyanasiyana (monga mitundu) ya kuwala kwa laser. Njira imeneyi imalola kulumikizana kwa mbali ziwiri pa ulusi umodzi, womwe umatchedwanso duplexing wavelength-division duplexing, komanso kuchulukitsa mphamvu.

-Dzina lonse la CWDM ndi Coarse Wavelength Division Multiplexing.

-Monga momwe dzinalo limanenera, ndi mtundu wa multiplexed fiber optics, kotero ma network a CWDM amatha kutumiza kulumikizana nthawi imodzi, njira ziwiri.

-Mawu akuti "coarse" amatanthauza kutalika kwa mafunde pakati pa njira.

-CWDM imagwiritsa ntchito zizindikiro za laser zomwe zimasiyana mu kukula kwa 20 nm. Pali njira 18 zosiyanasiyana zomwe zikupezeka — zomwe zimakhala ndi kutalika kwa mafunde kuyambira 1610 nm mpaka 1270 nm — ndipo 8 zingagwiritsidwe ntchito mu dongosolo limodzi. Popeza njira iliyonse imatha kufalitsa deta ya 3.125 Gbps, mphamvu yonse ndi 10 Gbps pa chingwe chilichonse cha CWDM.

-CWDM imagwiritsidwa ntchito pamtengo wotsika, mphamvu yochepa (sub-10G) komanso mtunda waufupi pomwe mtengo wake ndi wofunikira.

-CWDM ndi yabwino kwambiri pa ma network achangu komanso aatali omwe safuna liwiro lokwera mtengo. Ndi yabwinonso kwambiri pakusintha pang'onopang'ono machitidwe akale.

-CWDM ikhoza kukhala chingwe chanu chosinthasintha chomwe chimasunga zosankha zanu zotseguka, koma mutha kugwiritsabe ntchito mapangidwe ena a chingwe ngati pakufunika kutero.

Ubwino:

- Kakang'ono komanso kopepuka, ka mafakitale, kakhoza kuyikidwa mosavuta;

- Pulagi ndi kusewera, kuyika ndi kukonza mosavuta, palibe chifukwa chosinthira chilichonse;

- Kuchedwa konse kwa kutumiza, kukonza magwiridwe antchito a kutumiza, kuthandizira mtunda wautali;

- Pa maukonde opanda kuwala kwa fiber optic, palibe chifukwa cha mphamvu, kudalirika kwakukulu, kuthandizira kugwiritsa ntchito panja;

- Khalani owonekera bwino ku zizindikiro zilizonse zautumiki, imatha kuthandizira FE/GE/10GE/25GE/100GE, OTU1/OTU2/OTU3, FC1/2/4/8/10, STM1/4/16/64, ndi zina;
