Imiyoboro ya AON vs PON: Amahitamo ya sisitemu ya FTTH ya Fiber-to-the-Home

Fiber to the Home (FTTH) ni uburyo bushyiramo fibre optique kuva ahantu hagati mu nyubako imwe imwe kugeza ku nyubako imwe imwe nko mu ngo no mu mazu. Gukoresha FTTH byageze kure mbere y’uko abakoresha bakoresha fibre optique aho gukoresha umuringa kugira ngo babone interineti ya interineti.

Hari inzira ebyiri z'ibanze zo gushyiraho umuyoboro wa FTTH wihuta cyane:imiyoboro ikora y'urumuri(AON) na passiveimiyoboro y'urumuri(PON).

None se imiyoboro ya AON na PON: itandukaniro ni irihe?

Umuyoboro wa AON ni iki?

AON ni imiterere y'umuyoboro w'itumanaho aho buri mufatabuguzi afite umurongo we bwite wa fiber optique uhagarikwa kuri concentrator y'amajwi. Umuyoboro wa AON ugizwe n'ibikoresho bikoresha amashanyarazi nka routers cyangwa switching aggregators kugira ngo bicunge ikwirakwizwa ry'ibimenyetso no gutanga ibimenyetso mu cyerekezo ku bakiriya runaka.

Amadirishya afunguka kandi agafunga mu buryo butandukanye kugira ngo yohereze ibimenyetso byinjira n'ibisohoka ahantu hakwiye. Kuba umuyoboro wa AON wishingikiriza ku ikoranabuhanga rya Ethernet byoroshya imikoranire hagati y'abatanga serivisi. Abafatabuguzi bashobora guhitamo ibikoresho bitanga amakuru akwiye kandi bikazamuka uko ibyo bakeneye byiyongera batiriwe bongera gushyiraho umuyoboro. Ariko, imiyoboro ya AON isaba nibura umuhuza umwe w'amadirishya kuri buri mufatabuguzi.

Umuyoboro wa PON ni iki?

Bitandukanye na AON networks, PON ni imiterere y’urusobe rw’amakuru (point-to-multipoint network architecture) ikoresha passive splitters kugira ngo itandukane kandi ikusanye ibimenyetso by’urumuri. Fiber splitters zemerera PON network gukorera abafatabuguzi benshi muri fibre imwe bitabaye ngombwa ko hashyirwaho fibre zitandukanye hagati y’aho hantu n’umukoresha wa nyuma.

Nk’uko izina ribigaragaza, imiyoboro ya PON ntabwo irimo ibikoresho byo guhinduranya moteri ndetse n’udupira dusangiza ibice by’umuyoboro. Ibikoresho bikora bikenerwa gusa ku mpera z’ikimenyetso aho ikimenyetso gituruka n’aho cyakirwa.

Mu muyoboro usanzwe wa PON, agace ka PLC gatandukanya ni ko gashyirwa hagati. Utumashini twa fibre optique duhuza ibimenyetso byinshi bya optique mu muyoboro umwe, cyangwa utwo dumashini twa fibre optique dufata igikoresho kimwe cya optique maze tukabikwirakwiza mu muyoboro umwe umwe. Utwo dumashini twa PON turi mu cyerekezo cy’ibice bibiri. Kugira ngo bisobanuke neza, ibimenyetso bya fibre optique bishobora koherezwa mu buryo bunyura mu biro bikuru kugira ngo bitangazwe ku bafatabuguzi bose. Ibimenyetso bivuye ku bafatabuguzi bishobora koherezwa mu kirere hanyuma bigahuzwa mu muyoboro umwe kugira ngo bivugishe n’ibiro bikuru.

Imiyoboro ya AON vs PON: Itandukaniro n'Amahitamo

Imiyoboro ya PON na AON yombi igize umugongo wa fiber optique wa sisitemu ya FTTH, yemerera abantu n'ibigo gukoresha interineti. Mbere yo guhitamo PON cyangwa AON, ni ngombwa gusobanukirwa itandukaniro riri hagati yabyo.

Gukwirakwiza ibimenyetso

Ku bijyanye n'imiyoboro ya AON na PON, itandukaniro rikomeye riri hagati yayo ni uburyo ikimenyetso cy'urumuri gikwirakwizwa kuri buri mukiriya muri sisitemu ya FTTH. Muri sisitemu ya AON, abafatabuguzi bafite imiyoboro ya fibre yabugenewe, ituma bashobora kugera kuri bandwidth imwe, aho kugera kuri bandwidth imwe. Muri sisitemu ya PON, abafatabuguzi basangira igice cy'imiyoboro ya fibre ya network muri PON. Kubera iyo mpamvu, abantu bakoresha PON nabo bashobora gusanga sisitemu yabo itinda kuko abakoresha bose basangiye bandwidth imwe. Iyo habayeho ikibazo muri sisitemu ya PON, bishobora kugorana kubona inkomoko y'ikibazo.

Ibiciro

Igiciro kinini gihoraho mu muyoboro w'itumanaho ni ikiguzi cyo gukoresha ibikoresho no kubisana. PON ikoresha ibikoresho bidasaba gusanwa cyane kandi bidafite umuriro nk'umuyoboro wa AON, ari wo muyoboro ukora. Rero PON ihendutse kurusha AON.

Intera n'Ikoreshwa ry'Ubufasha

AON ishobora gukora intera igera kuri kilometero 90, mu gihe PON isanzwe igengwa n'imirongo ya fiber optique ifite uburebure bwa kilometero 20. Ibi bivuze ko abakoresha PON bagomba kuba bari hafi y'ikimenyetso cy'aho kiva.

Byongeye kandi, niba bifitanye isano na porogaramu cyangwa serivisi runaka, hari ibindi bintu byinshi bigomba kwitabwaho. Urugero, niba serivisi za RF na videwo zigomba gukoreshwa, noneho PON ni yo nzira yonyine ishoboka. Ariko, niba serivisi zose zishingiye kuri Internet Protocol, noneho PON cyangwa AON bishobora kuba bikwiye. Niba intera ndende irimo kandi gutanga ingufu no gukonjesha ibice bikora mu murima bishobora guteza ikibazo, noneho PON ishobora kuba amahitamo meza. Cyangwa, niba umukiriya ugamije ari ubucuruzi cyangwa umushinga urimo amazu menshi yo guturamo, noneho umuyoboro wa AON ushobora kuba mwiza kurushaho.

AON vs. PON Networks: Ni iyihe FTTH ukunda?

Mu guhitamo hagati ya PON na AON, ni ngombwa gusuzuma serivisi zizatangwa binyuze kuri interineti, imiterere rusange y'urubuga, n'abakiriya b'ibanze. Abakora benshi bakoresheje uburyo butandukanye bwo guhuza imiyoboro yombi. Ariko, uko gukenera gukoresha imiyoboro no kwaguka bikomeje kwiyongera, imiterere y'imiyoboro irimo kwemerera fibre iyo ari yo yose gukoreshwa mu buryo butandukanye muri porogaramu za PON cyangwa AON kugira ngo ihuze n'ibikenewe mu gihe kizaza.
