Nekufambira mberi kuri kuita indasitiri yekutaurirana kwemaziso, matekinoroji matsva uye mhinduro dzinochengetedza mari dziri kuramba dzichiwanikwa. Semuenzaniso, zvigadzirwa zveCWDM neDWDM zviri kushandiswa zvakanyanya, saka nhasi tichadzidza nezvezvigadzirwa zveCWDM neDWDM!
CWDM itekinoroji yekutumira WDM inodhura zvishoma yekushandisa network yemaguta. Inochengetedza mari yekushandisa fiber uye network, inogadzirisa matambudziko maviri ekushomeka kwefiber uye kutapurirana kwemasevhisi akasiyana-siyana zvakajeka. Network inogona kuvakwa uye bhizinesi rinogona kuitwa munguva pfupi.
Mabhenefiti eCWDM:
※ Chinhu chinonyanya kukosha cheCWDM mutengo wakaderera wemidziyo.
※ Inogona kuderedza mari yekushandisa network.
※ Inogona kuwedzera zvakanyanya kugona kwekutumira kwefiber ye optical uye kuvandudza kushandiswa kwezviwanikwa zvefiber ye optical.
※ Saizi diki uye kushandiswa kwesimba kushoma.
※ Ine kuchinjika kwakanaka uye kugona kukura
DWDM inogona kusanganisa uye kutumira mawavelength akasiyana mufiber imwe chete panguva imwe chete. Kuti ishande zvakanaka, fiber imwe inoshandurwa kuita mafiber akawanda chaiwo. DWDM inowanzova nemafomu maviri ekushandisa: DWDM yakavhurika uye DWDM yakabatanidzwa.
Mabhenefiti eDWDM:
※ Protocol yayo uye kumhanya kwayo kwekutumira hazvina basa.
※Multiplexer nesplitter yesystem yakabatanidzwa yeDWDM zvinoshandiswa zvakasiyana pamuchina wekutumira nekugamuchira
※ Midziyo yeDWDM yakabatana ine chimiro chiri nyore uye vhoriyamu diki, inenge chikamu chimwe muzvishanu chete chenzvimbo inogarwa neDWDM yakavhurika, zvichichengetedza zviwanikwa zvemakamuri emakomputa.
※Sisitimu yeDWDM yakabatanidzwa inoshandisa chete zvikamu zvisingashande (senge mamultiplexers kana ma demultiplexers) pakugamuchira nekutumira. Vashandi venharembozha vanogona kuisa maodha zvakananga kubva kuvagadziri vemidziyo, zvichideredza malink ekugovera uye kuderedza mitengo, nokudaro vachichengetedza mari yemidziyo.
CWDM neDWDM zvese zviri zviviri zvinopa wavelength division multiplexers, saka musiyano uripi pakati pazvo? CWDM (kureva, sparse wavelength division multiplexing) uye DWDM (kureva, dense wavelength division multiplexing), chaizvoizvo tinogona kuona musiyano uripo pakati pezviviri izvi: "dense" uye "sparse". Sparse Wavelength Division Multiplexing, sezvinoreva zita racho, ihama yepedyo yeDense Wavelength Division Multiplexing.
Kusiyana kwavo kunonyanya kuratidzwa muzvinhu zvitatu zvinotevera:
1) Nzvimbo yemugero wekutakura weCWDM yakafara, saka, mawavelength mashanu kusvika matanhatu chete emafungu echiedza anogona kuwanda pafiber imwe chete, uye musiyano uripo pakati pemazita ekuti "sparse" ne "dense" unobva pane izvi;
2) CWDM modulated laser inoshandisa laser isina kutonhora, nepo DWDM ichishandisa laser inotonhorera. Iyo laser inotonhorera inoshandisa kugadzirisa tembiricha, uye iyo laser isina kutonhora inoshandisa kugadzirisa kwemagetsi. CWDM ikozvino yava kufarirwa zvikuru nevanopa maapplication ebhizinesi. Zvichitaurwa zviri nyore: DWDM chikamu cheCWDM.
3) Nzvimbo yekushandisa michina yakasiyana. CWDM inonyanya kushandiswa mu convergence layer ne access layer; DWDM inoshandiswa munzvimbo yekushanda yekutaurirana kwenjanji.
