I-SONET (Inethiwekhi Yokubona Evumelanisiwe)
I-SONET iyindinganiso yokudlulisa inethiwekhi yesivinini esikhulu e-United States. Isebenzisa i-optical fiber njengendlela yokudlulisa ulwazi lwedijithali ku-ring noma ku-point-to-point layout. Embindini wayo, ivumelanisa ukugeleza kolwazi ukuze amasignali avela emithonjeni ehlukene akwazi ukuphindaphindwa ngaphandle kokulibala endleleni yesignali evamile yesivinini esikhulu. I-SONET imelelwa amazinga e-OC (optical carrier), njenge-OC-3, OC-12, OC-48, njll., lapho izinombolo zimelela khona ama-multiples eyunithi eyisisekelo i-OC-1 (51.84 Mbps). Ukwakhiwa kwe-SONET kuklanyelwe ngokuvikela okuqinile kanye namakhono okuzibuyisa, ngakho-ke kuvame ukusetshenziswa kumanethiwekhi omgogodla.
I-SDH (Uhlelo Lwedijithali Oluhambisanayo)
I-SDH ngokuyisisekelo ilingana ne-SONET yamazwe ngamazwe, esetshenziswa kakhulu eYurophu nakwezinye izifunda ezingezona zase-US. I-SDH isebenzisa amazinga e-STM (Synchronous Transport Module) ukuhlonza isivinini sokudlulisa esihlukile, njenge-STM-1, STM-4, STM-16, njll., lapho i-STM-1 ilingana no-155.52 Mbps. I-SDH ne-SONET ziyasebenzisana emininingwaneni eminingi yobuchwepheshe, kodwa i-SDH inikeza ukuguquguquka okwengeziwe, njengokuvumela izimpawu ezivela emithonjeni eminingi ehlukene ukuthi zihlanganiswe kalula kwi-fiber eyodwa ye-optical.
I-DWDM (Ukuphindaphinda Kwesigaba Sobude Obuqinile)
I-DWDM ubuchwepheshe bokudlulisa inethiwekhi ye-fiber optic obukhulisa i-bandwidth ngokudlulisa izimpawu eziningi ze-optical zama-wavelength ahlukene ngesikhathi esisodwa ku-fiber efanayo ye-optical. Izinhlelo ze-DWDM zingathwala izimpawu ezingaphezu kwe-100 zama-wavelength ahlukene, ngalinye lingabhekwa njengesiteshi esizimele, futhi isiteshi ngasinye singadlulisela ngamanani ahlukene nezinhlobo zedatha. Ukusetshenziswa kwe-DWDM kuvumela opharetha benethiwekhi ukuthi bandise kakhulu umthamo wenethiwekhi ngaphandle kokubeka izintambo ezintsha ze-optical, okubaluleke kakhulu emakethe yesevisi yedatha ngokukhula okukhulu kwesidingo.
Umehluko phakathi kwalaba abathathu
Nakuba ubuchwepheshe obuthathu bufana ngomqondo, busahlukile ekusebenzeni kwangempela:
Izindinganiso zobuchwepheshe: I-SONET kanye ne-SDH ziyizindinganiso zobuchwepheshe ezimbili ezihambisanayo. I-SONET isetshenziswa kakhulu eNyakatho Melika, kuyilapho i-SDH isetshenziswa kakhulu kwezinye izifunda. I-DWDM ubuchwepheshe bokuphindaphindwa kwamaza obusetshenziswa ekudluliseni izimpawu eziningi ezifanayo kunezindinganiso zefomethi yedatha.
Izinga ledatha: I-SONET ne-SDH zichaza izingxenye zezinga elimisiwe lokudluliswa kwedatha ngamazinga noma amamojula athile, kuyilapho i-DWDM igxile kakhulu ekwandiseni izinga lokudluliswa kwedatha ngokufaka iziteshi zokudlulisa ku-fiber efanayo ye-optical.
Ukuguquguquka kanye nokukhula: I-SDH inikeza ukuguquguquka okukhulu kune-SONET, okwenza kube lula ukuxhumana kwamazwe ngamazwe, kuyilapho ubuchwepheshe be-DWDM buhlinzeka ngokuguquguquka okukhulu kanye nokukhula kwesilinganiso sedatha kanye nokusetshenziswa kwe-spectrum, okuvumela inethiwekhi ukuthi ikhule njengoba isidingo sikhula.
Izindawo Zokusebenza: I-SONET ne-SDH zivame ukusetshenziselwa ukwakha amanethiwekhi omgogodla kanye nezinhlelo zawo zokuzivikela nokuzilungisa, kuyilapho i-DWDM iyisisombululo sokudluliselwa kwenethiwekhi ye-optical yebanga elide kanye nebanga elide kakhulu, esetshenziselwa ukuxhumana phakathi kwezikhungo zedatha noma kuzo zonke izinhlelo zekhebula zangaphansi kolwandle, njll.
Ngamafuphi, i-SONET, i-SDH kanye ne-DWDM ubuchwepheshe obubalulekile bokwakha amanethiwekhi okuxhumana e-optical fiber anamuhla nawesikhathi esizayo, futhi ubuchwepheshe ngabunye bunezimo zabo zokusebenza ezihlukile kanye nezinzuzo zobuchwepheshe. Ngokukhetha nokusebenzisa kahle lobu buchwepheshe obuhlukene, opharetha benethiwekhi bangakha amanethiwekhi okudlulisa idatha asebenzayo, athembekile futhi asheshayo emhlabeni jikelele.
Sizoletha imikhiqizo yethu ye-DWDM kanye ne-DCI BOX ukuze sihambele uMkhosi we-Africa Tech, imininingwane ilandelayo:
