Ibhizinisi lobuchwepheshe obuphezulu eligxile ocwaningweni nasekuthuthukisweni kwezokuxhumana kanye nokukhiqizwa kwefiber optical.
Imvelaphi ye-ODN
Ekhulwini lama-20, amanethiwekhi okufinyelela ahamba phambili ayethembele cishe kuphela engqalasizinda yethusi. Ukufika kobuchwepheshe be-Passive Optical Network (PON) ekuqaleni kwekhulu lama-21 kwaphawula ushintsho olukhulu. I-PON yethule ukwakheka kwe-fiber-optic, okukhomba-kuya-kumaphuzu amaningi okukwazi ukusekela izinsizakalo zezwi, ividiyo, kanye nedatha ezihlanganisiwe ezinezimpawu ze-bandwidth kanye ne-latency ephezulu. Lo mklamo wakhelwe phezu kwesitshalo se-passive fiber: Ama-Optical Line Terminals (OLTs) axhuma kuma-Passive Optical Splitters, abese esakaza amasignali kuma-Optical Network Units amaningi (ONUs) ezindaweni zamakhasimende. Le ngqalasizinda ebalulekile ye-fiber kanye ne-splitter ihlanganisa i-Optical Distribution Network (ODN).
Ukuvela Kobuchwepheshe be-ODN
Nakuba i-ODN iwungqimba olungasebenzi, yakha into edinga imali eningi kakhulu futhi ethinta kakhulu ukuthunyelwa kwamaphrojekthi e-FTTx. Ngakho-ke, ukuthuthuka okuqhubekayo kobuchwepheshe be-ODN bekulokhu kuhlose ukunciphisa izinselele zokwakha nokwenza kube lula ukusebenza.
I-ODN Ehlanganisiwe Yendabuko
Ukwakhiwa kwe-ODN yendabuko noma yesizukulwane sokuqala, okwasetshenziswa iminyaka engaphezu kwamashumi amathathu ngesikhathi esifanayo nokwandiswa kwe-FTTx yomhlaba wonke, kuseyindlela yokufinyelela ifayibha etholakala kabanzi namuhla. Isici sayo esichazayo isidingo esibanzi sokuxhuma insimu. Ingxenye ngayinye—kusukela ezintanjeni ze-feeder kanye nezokusabalalisa kuya entanjeni yokugcina yokudonsa—idinga ukuhlubula ngesandla kanye nokuxhumanisa i-fusion. Ukufakwa kudinga umsebenzi omkhulu wasensimini: ukuvula izindawo eziningi zokuvala, ukulungiselela ikhebula ngokucophelela, kanye nokusebenza kokuxhumanisa okunekhono kokubili ezindaweni zangaphandle nangaphakathi.
Ukuze kunqotshwe izinselele zasensimini ze-ODN Yendabuko—ikakhulukazi ezindaweni ezidinga kakhulu—i-ODN Engaqedwanga kanye ne-Modular (i-ODN yesizukulwane sesibili) inikeza enye indlela elula. Yenzelwe ukuqeda ukuhlanganiswa kwe-fusion endaweni, ngaleyo ndlela kusheshiswe ukuthunyelwa futhi kwehliswe izidingo zabasebenzi. Isihluthulelo ukucushwa kwangaphambi kwesikhathi: ama-splitter afakwa ngaphambilini ngaphakathi kokuvalwa, futhi wonke ama-fiber aqedwa efektri. Lokhu kuvumela ukufakwa kwe-plug-and-play ensimini, lapho ochwepheshe bexhuma khona amakhebula aqedwa ngaphambilini ekuvalweni. Ngaphezu kwalokho, le ndlela isekela imodeli yokuthunyelwa ehlukaniswe ngezigaba kusetshenziswa amakhebula amaningi ngamanye, ihlukanise amakhebula kumadivayisi, futhi ivumele ukuhamba komsebenzi okuhambisanayo kokwakha.
Ukuqamba okusha okuphawulekayo kwesizukulwane sesibili se-ODN—ukufakwa kwelebula kwedijithali kwemicu nama-port ngama-barcode/amakhodi e-QR—kwenze kwaba lula ukuphathwa kokubukwayo ngesizindalwazi esihlakaniphile. Kodwa-ke, njengoba lokhu kubonwa kungakwazi ukubona noma ukulungisa amaphutha ngokuzimela, abasebenzi bezobuchwepheshe kusamele bangenelele ngesandla.
Ukubhekana nalesi sikhala, i-ODN yesizukulwane sesithathu iqhubekela phambili ngale kokuqedwa kwangaphambi kokuphela ngokufaka amakhono edijithali nawobuhlakani, okuhlanganisa ukuqashelwa kwezithombe okusekelwe ku-AI kanye nokuphathwa kwamafu. Lokhu kuthuthuka kuhlose ukubhekana nezinselele zokusebenza zesikhathi eside ngokwenza izinsiza ze-ODN zibonakale ngokuphelele futhi zilawuleke.
Zisebenzisa ubuchwepheshe bokuqapha okubonakalayo (njengezindlela ezisuselwe ekukhanyeni noma ekubambezelekeni), izinhlelo zokuphatha ezihlakaniphile manje zibona ngokuzenzakalelayo futhi zenze amaphutha abe sendawo ku-fiber noma i-port eqondile. Idatha yamaphutha idluliselwa kalula esikhungweni sokusebenza kwenethiwekhi kanye namadivayisi ochwepheshe basensimini. Uhlelo lwe-“Fiber Iris” lwe-Huawei luyisibonelo, lusebenzisa ukuzwa okuhlakaniphile ukuthuthukisa ukutholwa kwamaphutha kanye nokusebenza kahle kokulungisa.
Ukukhetha i-ODN efanele kuncike ekuvumelaniseni amakhono ayo nezidingo ezithile zokuthunyelwa. Ngenkathi ubuchwepheshe be-ODN buthuthukele ezixazululweni ezihlakaniphile zesizukulwane sesithathu, izakhiwo zesizukulwane sokuqala nesesibili azigcini nje ngokuba wusizo kodwa futhi zisezingeni eliphezulu ezimweni ezithile.
I-ODN Ehlanganisiwe Yendabuko: Ukuze Uguquguquke Kakhulu
Lapho izidingo zihlukahluka kakhulu—njengalapho ubude befayibha bungaqinisekile noma inani lezixhumi lidinga ukunqunywa endaweni—i-ODN evamile yesizukulwane sokuqala iyisinqumo esiwusizo. Ivumela ochwepheshe ukuthi bahlele inethiwekhi ngokunembile ngokwezimo zasensimini, baqinisekise ukusetshenziswa kwezinsiza kusebenza kahle kanye nokuxhumeka okuthembekile, okulahlekelwa kakhulu.
I-ODN Eqediwe Ngaphambili: Yesivinini Nokulula
Izixazululo eziqediwe kusengaphambili zesizukulwane sesibili ziyaphumelela lapho ukukhishwa okusheshayo kubalulekile noma ukufinyelela kusayithi kuyinselele. Amacala okusetshenziswa afanele afaka:
Izindawo ezikude noma ezinezintaba okunzima ukufinyelela kuzo.
Amaphrojekthi adinga ukumbozwa okusheshayo kwezindawo eziningi.
Ukwandiswa kwenethiwekhi okwesikhashana noma okuphuthumayo.
Uhlobo lwazo lokuxhuma nokudlala luthuthukisa kakhulu ukusebenza kahle kokufakwa, lunciphisa izindleko zabasebenzi, futhi lunciphisa amaphutha okufakwa.
I-ODN Ehlakaniphile: Yemisebenzi Ezenzakalelayo
I-ODN 3.0, enokuqapha okuhlanganisiwe kwedijithali, ukutholwa kwamaphutha okuzenzakalelayo, kanye nokuphathwa okukude, ilungele opharetha ababeka phambili ukuzenzekela kokusebenza kanye nokubonakala kwesikhathi sangempela. Nakuba idinga ukutshalwa kwezimali kokuqala okuphezulu, inikeza ukonga kokusebenza kwesikhathi eside kanye nokuthembeka okuthuthukisiwe kwamanethiwekhi lapho ukuphathwa okuhlelekile kubaluleke kakhulu.
Isiphetho
Njengoba izidingo ze-broadband ziqhubeka nokukhula, ama-Optical Distribution Networks (ODN) ayashintsha ngokufanele, eshintsha esuka ezindleleni ezidinga abasebenzi abaningi aye ezinhlelweni zedijithali ezizenzakalelayo, ezihlakaniphile, nezithembekile kakhulu. Ukukhetha ikhambi elifanele le-ODN kubalulekile kubasebenzi ukuze bafinyelele ukuthunyelwa okusheshayo, ukuphathwa okuphumelelayo, kanye nendlela yokuthuthuka ebushelelezi yobuchwepheshe be-PON besikhathi esizayo.
Uma uhlela ukuthuthukiswa kwe-ODN noma ufuna ukwakheka kwenethiwekhi okungcono kakhulu, i-KEXINT inikeza isiqondiso sochwepheshe kanye nezixazululo zokufakwa kwe-FTTx ezenzelwe wena. Xhumana nathi namuhla.
