Umahluko phakathi kweSONET, iSDH kunye neDWDM

I-SONET (Uthungelwano oluKhethekileyo oluVumelanayo)
I-SONET ngumgangatho wothumelo lwenethiwekhi yesantya esiphezulu eUnited States. Isebenzisa i-fiber optical njengendlela yokudlulisa ulwazi kwi-digital kwi-ring or point-to-point layout. Kwisiseko sayo, ivumelanisa ukuhamba kolwazi ukwenzela ukuba izibonakaliso ezivela kwimithombo eyahlukeneyo zikwazi ukuphindaphinda ngaphandle kokulibaziseka kwindlela yophawu oluqhelekileyo lwesantya esiphezulu. I-SONET imelwe ngamanqanaba e-OC (i-optical carrier), njenge-OC-3, i-OC-12, i-OC-48, njl., apho amanani amele ukuphindaphinda kweyunithi eyisiseko OC-1 (51.84 Mbps). Uyilo lwe-SONET lwenzelwe ukhuseleko oluluqilima kunye namandla okuzibuyisela, ngoko ke isetyenziswa rhoqo kwiinethiwekhi zomqolo.

I-SDH (i-Synchronous Digital Hierarchy)
I-SDH ngokusisiseko ilingana namazwe ngamazwe e-SONET, esetyenziswa kakhulu eYurophu nakweminye imimandla engeyiyo yase-US. I-SDH isebenzisa amanqanaba e-STM (i-Synchronous Transport Module) ukuchonga isantya esihlukeneyo sothumelo, njenge-STM-1, STM-4, STM-16, njl., apho i-STM-1 ilingana ne-155.52 Mbps. I-SDH kunye ne-SONET ziyasebenzisana kwiinkcukacha ezininzi zobugcisa, kodwa i-SDH inikeza ukuguquguquka okungaphezulu, njengokuvumela iimpawu ezivela kwimithombo emininzi eyahlukeneyo ukuba zidibaniswe lula kwi-fiber optical eyodwa.

I-DWDM (iCandelo le-Wavelength elixineneyo lokuphindaphinda)
I-DWDM yitekhnoloji ye-fiber optic yothumelo lwenethiwekhi eyandisa i-bandwidth ngokuthumela izibonakaliso ezininzi ze-optical wavelengths ezahlukeneyo ngaxeshanye kwifiber optical efanayo. Iinkqubo ze-DWDM zinokuthwala izibonakaliso ezingaphezu kwe-100 zamaza ahlukeneyo, nganye nganye inokuthathwa njengejelo elizimeleyo, kwaye ishaneli nganye inokudlulisa kwiinqanaba ezahlukeneyo kunye neentlobo zedatha. Ukusetyenziswa kwe-DWDM kuvumela abaqhubi benethiwekhi ukuba bakhulise kakhulu umthamo womnatha ngaphandle kokubeka iintambo ezintsha ze-optical, ezibaluleke kakhulu kwimarike yenkonzo yedatha kunye nokukhula okukhulayo kwimfuno.

Umahluko phakathi kwabathathu
Nangona iitekhnoloji ezintathu ziyafana kwingqikelelo, zisahluka kwisicelo sokwenyani:

Imigangatho yobugcisa: I-SONET kunye ne-SDH ubukhulu becala yimigangatho emibini ehambelanayo yobugcisa. I-SONET isetyenziswa kakhulu eNyakatho Melika, ngelixa i-SDH isetyenziswa ngokuqhelekileyo kwezinye iindawo. I-DWDM yiteknoloji ye-multiplexing ye-wavelength esetyenziselwa ukuhanjiswa kweempawu ezininzi ezifanayo kunemigangatho yefomathi yedatha.

Ireyithi yedatha: I-SONET kunye ne-SDH zichaza amacandelo esantya esisisigxina sokuhanjiswa kwedatha ngamanqanaba athile okanye iimodyuli, ngelixa i-DWDM igxile ngakumbi ekunyuseni izinga lokuhanjiswa kwedatha ngokubanzi ngokufaka iziteshi zokuhambisa kwifiber ebonakalayo efanayo.

I-Flexibility and scalability: I-SDH inikezela ngokuguquguqukayo ngakumbi kune-SONET, iququzelela unxibelelwano lwamazwe ngamazwe, ngelixa iteknoloji ye-DWDM inikezela ukuguquguquka okukhulu kunye nokulinganisa kwizinga ledatha kunye nokusetyenziswa kwe-spectrum, evumela ukuba inethiwekhi yandise njengoko imfuno ikhula.

Iindawo zesicelo: I-SONET kunye ne-SDH zihlala zisetyenziselwa ukwakha i-backbone networks kunye nokukhusela kwazo kunye neenkqubo zokuzibuyisela, ngelixa i-DWDM iyisisombululo sokuhamba kwexesha elide kunye ne-ultra-long-long-long-long-distance optical network transmission, esetyenziselwa ukudibanisa phakathi kwamaziko edatha okanye kwi-submarine. iinkqubo zentambo, njl.

Isishwankathelo, i-SONET, i-SDH kunye ne-DWDM ziiteknoloji eziphambili zokwakha i-fiber optical network yanamhlanje kunye nexesha elizayo, kwaye iteknoloji nganye ineemeko zayo ezikhethekileyo zesicelo kunye neenzuzo zobugcisa. Ngokukhetha ngokufanelekileyo kunye nokuphumeza obu buchwepheshe bahlukeneyo, abaqhubi benethiwekhi banokwakha uthungelwano lwedatha olusebenzayo, oluthembekileyo kunye nesantya esiphezulu sothumelo lwedatha emhlabeni jikelele.

Siza kuzisa iimveliso zethu ze-DWDM kunye ne-DCI BOX ukuza kuMnyhadala weTekhnoloji we-Afrika, iinkcukacha ngolu hlobo lulandelayo:
Booth NO. yi D91A,
Umhla:Novemba 12-14th, 2024.
Yongeza:IZiko leeNgqungquthela laseKapa (CTICC)

Ndiyathemba ukukubona apho!
