Zvichienderana nekukura kuri kuita zvinhu zviri mu network, indasitiri ye telecommunications iri kuramba ichitarisana nedambudziko guru rekukura. Imwe ye tekinoroji huru mu optical communications — Wavelength Division Multiplexing (WDM) — yave mhinduro huru yekukunda matambudziko aya emuviri.

Kana fiber yemaziso ichienzaniswa nemugwagwa mukuru, kutaurirana kwekare kwehurefu hwemafungu rimwe chete kwakafanana nemota imwe chete iri mumugwagwa wese. Tekinoroji yeWDM inoparadzanisa nzira iyi chaiyo kuita "nzira dzechokwadi" dzakawanda dzisingapindiri (mafungu akasiyana emaziso), zvichibvumira masaini edata akawanda kutumirwa panguva imwe chete kuburikidza nefiber imwe chete. Hardware huru inogonesa tekinoroji iyi ipassive DWDM (Dense Wavelength Division Multiplexing) filter. Chinyorwa chino chinopa ongororo pfupi yetekinoroji iyi.

Izwi rekuti "passive" rinoreva kuti mudziyo uyu haudi chero magetsi ekunze. Asi, unovimba zvizere nekupenda kwakanyatsogadzirwa neoptical thin-film coatings kana grating structures kuti uparadzanise nemazvo (demultiplex) kana kubatanidza (multiplex) optical signals dzema wavelength akasiyana.

Hunhu uhwu hwekuona hunopa kugadzikana uye kuvimbika kwakanyanya, zvichiita kuti chishandiso ichi chisanyanya kukanganiswa nemagetsi. Nekuda kweizvozvo, chakakodzera kushandiswa kwenguva refu mumakamuri emidziyo yemafoni kana munzvimbo dzakaoma dzekunze.

Mukati mehurongwa hwe optical network, ma "passive DWDM filters" anoshanda se "traffic controllers." Anonyatsotevedzera mitemo yeInternational Telecommunication Union (ITU-T), achikamura hwindo re optical transmission rine kurasikirwa kwakaderera kuita makumi kana mazana enzira dzekutaurirana dzakazvimiririra dzine nzvimbo yakamanikana zvikuru yewavelength.

Izvi zvinoreva kuti fiber imwe chete ye optical, pakutanga yaikwanisa kutakura chiratidzo chimwe chete, inogona kuwedzera simba rayo rekutumira nekukurumidza kakawanda, zvichivandudza kushanda zvakanaka kwe spectral.

II. Maitiro Akajairika Ekushandisa uye Kukosha

Mafirita aya anowanzo gadzirwa nemagadzirirwo akajairwa ekurongedza, akadai seLGX cassette modules kana makadhi e19-inch rack-mount, uye ane mafiber optic connectors akanyatsogadzirwa kuti asanganiswe zvakanaka muma single-mode fiber network aripo. Mashandisirwo azvo akakosha anosanganisira:

Kuwedzera kweMetropolitan Transmission neBackbone Network

Pasina kuwedzera tambo itsva dzefiber, tekinoroji yeWDM inogona kukurumidza kuwedzera bandwidth yekutumira data yema network emumaguta makuru uye ma network emusana edunhu, zvichizadzisa zvinodiwa zve data zvakanyanya zvemasevhisi akadai se high-definition video streaming uye cloud computing.

Nzvimbo yekunze (OSP) uye Manetiweki ekuwana

Nekuda kwehunhu hwadzo hwekushanda pasina kugadzirisa, zvishandiso izvi zvinoshandiswa zvakanyanya muma network ekuparadzira ma optical ekunze, zvichideredza zvinobudirira mari yekushanda kwenguva refu uye yekugadzirisa kune vanoshanda nefoni.

Kubatana kweData Center

Mukati menzvimbo dzedata kana pakati penzvimbo dzakawanda dzedata, mafirita asingashande anogonesa kufambiswa kwemashoko akawanda emaziso nekushanda zvakanaka uye kurasikirwa kwakanyanya kwekuisa, zvichiita kuti data ritumirwe nekukurumidza uye kwakasimba.
