Amanethiwekhi we-Aon vs Pon: Izinketho zezinhlelo ze-fiber-to-the-home FTth

I-fiber to the Home (FTTH) uhlelo olufaka i-fiber Optics kusuka endaweni ephakathi nendawo ngqo ezakhiweni zamazazi ngazinye njengamakhaya namafulethi. Ukuthunyelwa kwe-FTT kufike isikhathi eside ngaphambi kokuba abasebenzisi bamukele i-fiber optics esikhundleni sethusi lokufinyelela kwe-inthanethi ebanzi.

Kunezindlela ezimbili eziyisisekelo zokusebenzisa inethiwekhi ephezulu ye-ftth:amanethiwekhi asebenzayo asebenzayo(Aon) nokwenza njeAmanethiwekhi we-Optical(Pon).

Ngakho-ke amanethiwekhi we-AON NE-PON: Uyini umehluko?

Iyini inethiwekhi ye-AON?

I-AON iyindawo yokwakhiwa kwenethiwekhi ye-point-to-point lapho umuntu obhalisile enomugqa wawo we-fiber optic onqanyulwa ku-optical accentrator. Inethiwekhi ye-AON efaka amadivaysi ahlelwe ngogesi anikwe amandla kagesi njengama-routers noma ama-aggniating agwini ukuphatha ukusatshalaliswa kwesiginali kanye nokusayina okuqondayo kumakhasimende athile.

Ukushintshwa kuvuliwe futhi kuvaliwe ngezindlela ezahlukahlukene zokuqondisa amasiginali angenayo naphumayo ezindaweni ezifanele.Ikuthembela kwenethiwekhi ye-Aon kubuchwepheshe be-Ethernet kwenza ukusebenzisana phakathi kwabahlinzeki kube lula phakathi kwabahlinzeki. Ababhalisile bangakwazi ukukhetha i-Hardware enikeza amanani afanele edatha kanye nezilinganiso njengoba izidingo zabo zikhuphuka ngaphandle kokuthola kabusha inethiwekhi. Kodwa-ke, amanethiwekhi e-AON adinga okungenani i-aggregator eyodwa yokushintshana.

Iyini inethiwekhi ye-PON?

Ngokungafani namanethiwekhi we-AON, i-PON iyi-pointipued yenethiwekhi yokwakha inethiwekhi esebenzisa ukuhlukaniswa nje kokuhlukanisa nokuqoqa amasiginali we-optical. Ama-fiber splitters avumela inethiwekhi ye-PON ukusebenzela ababhalisile abaningi ku-fiber eyodwa ngaphandle kwesidingo sokuhambisa imicu ehlukile phakathi kweHub kanye nomsebenzisi wokugcina.

Njengoba igama libonisa, amanethiwekhi we-PON awafaki imishini yokushintsha yemoto futhi abelane ngezinqwaba zefayibha ukuze izingxenye zenethiwekhi. Okokusebenza okusebenzayo kudingeka kuphela emthonjeni nokwamukela iziphetho zesiginali.

Kunethiwekhi ye-PON ejwayelekile, i-PLC Splitter iyisizinda. Ompompi be-fiber optic bahlanganisa amasiginali amaningi we-optical ekukhishweni okukodwa, noma ompompi be-fiber optic bathatha okokufaka okukodwa futhi basabalalise kumiphumela eminingi. Lawa ampompi we-PON arirectional. Ukucaca, amasiginali we-fiber optic angathunyelwa phansi emfuleni aqhamuka ehhovisi eliphakathi ukuze asakaze kubo bonke ababhalisile. Amasiginali avela kubabhalisile angathunyelwa phezulu futhi ahlanganiswe ne-fiber eyodwa ukuxhumana nehhovisi eliphakathi.

I-Aon vs Pon Networks: Umehluko Nokukhethwa

Womabili amanethiwekhi we-pon ne-aon akha umgogodla we-fiber optic ohlelweni lwe-FTT, avumela abantu namabhizinisi ukufinyelela kwi-Intanethi. Ngaphambi kokukhetha i-pon noma i-aon, kubalulekile ukuqonda umehluko phakathi kwabo.

Ukusatshalaliswa kwesiginali

Uma kukhulunywa ngamanethiwekhi we-Aon nasePon, umehluko omkhulu phakathi kwawo yindlela isiginali ye-Optical esatshalaliswa ngayo kwikhasimende ngalinye ohlelweni lwe-FTTH. Ohlelweni lwe-AON, ababhalisile banezinyanda ezinikezele ze-fiber, ezibavumela ukuthi bakwazi ukufinyelela umkhawulokudonsa ofanayo, kunokuba babe munye. E-PON Network, ababhalisile babelana ngengxenye ye-fiber bundle yenethiwekhi e-pon. Ngenxa yalokhu, abantu abasebenzisa i-pon bangathola nokuthi uhlelo lwabo luhamba kancane ngoba bonke abasebenzisi babelana nge-bandwidth efanayo. Uma kwenzeka inkinga ngaphakathi kohlelo lwe-PON, kungaba nzima ukuthola umthombo wenkinga.

Izindleko

Izindleko ezinkulu kakhulu eziqhubekayo kunethiwekhi yizindleko zemishini yokufaka amandla nokulungiswa. I-PON isebenzisa amadivaysi angenayo adinga ukulungiswa okuncane futhi akukho okuhlinzekwayo kwamandla kunenethiwekhi ye-AON, okuyinethiwekhi esebenzayo. Ngakho-ke i-pon ishibhile kune-Aon.

Ukumbozwa Ibanga Nezicelo

I-AON ingamboza uhla lwebanga olufinyelela kumakhilomitha angama-90, kanti i-PON luvame ukukhawulelwa ngamakhilomitha we-fiber optic kuze kube ngamakhilomitha angama-20 ubude. Lokhu kusho ukuthi abasebenzisi be-pon kumele basondele ngokwendawo kwisiginali esuka kulo.

Ngaphezu kwalokho, uma kuhlotshaniswa nohlelo oluthile noma insizakalo, ezinye izinto eziningi ezidinga ukubhekwa. Isibonelo, uma izinsizakalo ze-RF nevidiyo zizothunyelwa, khona-ke i-PON imvamisa yiso kuphela isisombululo esisebenzayo. Kodwa-ke, uma zonke izinsizakalo zisetshenziselwa i-Intanethi, khona-ke i-pon noma i-aon ingahle ilunge. Uma amabanga amade ebandakanyeka futhi ahlinzeke amandla futhi apholise ezintweni ezisebenzayo emkhakheni angaba yinkinga, khona-ke i-pon ingaba yisinqumo esihle kakhulu. Noma, uma ikhasimende eliqondiswe kulo ihweba noma iphrojekthi ifaka amayunithi amaningi okuhlala, khona-ke inethiwekhi ye-AON ingahle ilunge ngokwengeziwe.

I-Aon vs Pon Networks: Yiliphi ukhetha i-FTTH?

Lapho ukhetha phakathi kwe-pon noma i-AON, kubalulekile ukubheka ukuthi yiziphi izinsizakalo ezizolethwa kunethiwekhi, i-topology yenethiwekhi yonke, nokuthi amakhasimende aphambili akhona. Ama-opharetha amaningi athumele ukuhlanganiswa kwamanethiwekhi womabili ezimweni ezihlukile. Kodwa-ke, njengoba isidingo sokusebenzisana kwenethiwekhi kanye nokukhubazeka kuqhubeka ukukhula, izakhiwo zenethiwekhi zinakekela ukuvumela noma iyiphi i-fiber isetshenziswe ngokushintshana ngokushintshana ku-pon noma izicelo ze-aon ukufeza izidingo zezidingo zesikhathi esizayo.
