Imiyoboro ya AON vs PON: Amahitamo ya Fibre-Kuri-Murugo FTTH Sisitemu

Fibre to Home (FTTH) ni sisitemu ishyira fibre optique kuva kumurongo wo hagati ugana mumazu kugiti cye nk'amazu n'amagorofa. Kohereza FTTH bigeze kure mbere yuko abakoresha bemera fibre optique aho kuba umuringa kugirango bagere kuri interineti.

Hariho inzira ebyiri zifatizo zo gukoresha umuyoboro wihuse wa FTTH:imiyoboro ikora neza(AON) na pasiporoimiyoboro ya optique(PON).

Imiyoboro ya AON na PON rero: itandukaniro irihe?

Umuyoboro wa AON ni iki?

AON ni umurongo-ku-ngingo y'urusobekerane aho buri mufatabuguzi afite umurongo wa fibre optique urangirira kuri optique. umuyoboro wa AON ukubiyemo ibikoresho byo guhinduranya amashanyarazi nkamashanyarazi cyangwa guhinduranya abaterankunga kugirango bayobore ikwirakwizwa ryibimenyetso hamwe nibyerekezo byerekanwa kubakiriya runaka.

Guhindura bifunguye kandi bizimya muburyo butandukanye bwo kuyobora ibimenyetso byinjira nibisohoka ahantu hakwiye.Urusobe rwa AON kwishingikiriza kuri tekinoroji ya Ethernet bituma imikoranire hagati yabatanga byoroshye. Abiyandikisha barashobora guhitamo ibyuma bitanga igipimo cyamakuru gikwiye kandi bakaguka uko ibyo bakeneye byiyongera bitabaye ngombwa ko bongera guhuza urusobe. Nyamara, imiyoboro ya AON isaba byibura igiteranyo kimwe cyo guhuza abiyandikisha.

Umuyoboro wa PON ni iki?

Bitandukanye numuyoboro wa AON, PON nigitekerezo-cyo-kugwiza imiyoboro yububiko ikoresha pasiporo igabanya gutandukanya no gukusanya ibimenyetso bya optique. Gutandukanya fibre yemerera umuyoboro wa PON gukorera abafatabuguzi benshi muri fibre imwe bitabaye ngombwa kohereza fibre zitandukanye hagati ya hub numukoresha wa nyuma.

Nkuko izina ribigaragaza, imiyoboro ya PON ntabwo ikubiyemo ibikoresho byo guhinduranya moteri no kugabana fibre bundle kubice byurusobe. Ibikoresho bifatika bisabwa gusa kubisoko no kwakira impera yikimenyetso.

Mubisanzwe bisanzwe PON, ibice bya PLC nibyo hagati. Fibre optique ikomatanya ibimenyetso byinshi bya optique mubisohoka kimwe, cyangwa fibre optique ifata optique imwe hanyuma ikayikwirakwiza mubisubizo byinshi. Kanda kuri PON ni ibyerekezo byombi. Kugira ngo bisobanuke neza, ibimenyetso bya fibre optique birashobora koherezwa munsi yu biro bikuru kugirango bigere ku bafatabuguzi bose. Ibimenyetso by'abafatabuguzi birashobora koherezwa hejuru hanyuma bigahuzwa muri fibre imwe kugirango ivugane n'ibiro bikuru.

Imiyoboro ya AON vs PON: Itandukaniro namahitamo

Imiyoboro yombi ya PON na AON ikora fibre optique ya sisitemu ya FTTH, ituma abantu nubucuruzi bagera kuri enterineti. Mbere yo guhitamo PON cyangwa AON, ni ngombwa kumva itandukaniro riri hagati yabo.

Ikwirakwizwa ry'ikimenyetso

Iyo bigeze kumurongo wa AON na PON, itandukaniro nyamukuru hagati yabo nuburyo ibimenyetso bya optique bigabanywa buri mukiriya muri sisitemu ya FTTH. Muri sisitemu ya AON, abiyandikishije bafite imigozi ya fibre yihariye, ibemerera kubona umurongo umwe, aho kuba umwe. Mumuyoboro wa PON, abafatabuguzi basangiye igice cyurusobe rwa fibre bundle muri PON. Nkigisubizo, abantu bakoresha PON barashobora kandi kubona ko sisitemu yabo itinda kuko abakoresha bose basangiye umurongo umwe. Niba ikibazo kibaye muri sisitemu ya PON, birashobora kugorana kubona inkomoko yikibazo.

Ikiguzi

Amafaranga menshi akomeje murusobe nigiciro cyibikoresho byamashanyarazi no kubungabunga. PON ikoresha ibikoresho byoroshye bisaba kubungabungwa bike kandi nta mashanyarazi arenze umuyoboro wa AON, numuyoboro ukora. PON rero ihendutse kuruta AON.

Gupfukirana Intera na Porogaramu

AON irashobora gukora intera igera kuri kilometero 90, mugihe PON isanzwe igarukira kumirongo ya fibre optique igera kuri kilometero 20. Ibi bivuze ko abakoresha PON bagomba kuba hafi ya geografiya hafi yikimenyetso cyaturutse.

Mubyongeyeho, niba bifitanye isano na porogaramu cyangwa serivisi runaka, hagomba gusuzumwa ibindi bintu byinshi. Kurugero, niba serivisi za RF na videwo zigomba koherezwa, noneho PON mubisanzwe igisubizo cyonyine gishoboka. Ariko, niba serivisi zose zishingiye kuri enterineti ishingiye kuri enterineti, noneho PON cyangwa AON irashobora kuba ikwiye. Niba intera ndende irimo no gutanga imbaraga no gukonjesha ibice bikora mumurima birashobora kuba ikibazo, noneho PON irashobora guhitamo neza. Cyangwa, niba umukiriya ugamije ari ubucuruzi cyangwa umushinga urimo ibice byinshi byo guturamo, noneho umuyoboro wa AON urashobora kuba mwiza.

AON na PON Networks: Ninde FTTH ukunda?

Mugihe uhisemo hagati ya PON cyangwa AON, ni ngombwa gusuzuma serivisi zizatangwa kurubuga, rusange muri rusange topologiya, hamwe nabakiriya bambere abo aribo. Abakoresha benshi bohereje kuvanga imiyoboro yombi mubihe bitandukanye. Nyamara, nkuko bikenewe guhuza imiyoboro hamwe nubunini bikomeje kwiyongera, ubwubatsi bwurusobe bugenda bwemerera fibre iyo ari yo yose gukoreshwa muburyo bumwe muri porogaramu ya PON cyangwa AON kugirango ihuze ibyifuzo byigihe kizaza.
