AON vs PON Networks: Likhetho tsa Fiber-to-the-Home FTTH Systems

Fiber to the Home (FTTH) ke sistimi e kenyang fiber optics ho tloha sebakeng se bohareng ka kotloloho ho ea meahong e ikemetseng joalo ka matlo le lifolete. Tšebeliso ea FTTH e tsamaile nako e telele pele basebelisi ba amohela fiber optics sebakeng sa koporo bakeng sa phihlello ea Marang-rang.

Ho na le litsela tse peli tsa mantlha tsa ho tsamaisa marang-rang a lebelo le phahameng la FTTH:marang-rang a sebetsang a optical(AON) le ho se etse lethomarang-rang a optical(PON).

Kahoo marang-rang a AON le PON: phapang ke efe?

Marang-rang a AON ke eng?

AON ke mohaho oa marang-rang oa ntlha-to-point moo mofani e mong le e mong a nang le mohala oa hae oa fiber optic o felisitsoeng ho concentrator optical. marang-rang a AON a kenyelletsa lisebelisoa tse fetohang tse tsamaisoang ke motlakase tse kang li-routers kapa li-switching aggregator ho laola kabo ea matšoao le matšoao a tataiso ho bareki ba itseng.

Li-switches li buloa le ho tima ka litsela tse sa tšoaneng ho lebisa matšoao a kenang le a tsoang libakeng tse loketseng.Ho itšetleha ha marang-rang a AON ho thekenoloji ea Ethernet ho etsa hore tšebelisano-'moho e be bonolo pakeng tsa bafani. Ba ngolisitseng ba ka khetha hardware e fanang ka litekanyetso tse nepahetseng tsa data le ho eketseha ha litlhoko tsa bona li ntse li eketseha ntle le ho lokisa marang-rang. Leha ho le joalo, marang-rang a AON a hloka bonyane aggregator e le 'ngoe ea switjha ka mong ea ngolisitseng.

Marang-rang a PON ke eng?

Ho fapana le marang-rang a AON, PON ke meralo ea marang-rang ea ntlha-to-multipoint e sebelisang li-splitter tse sa sebetseng ho arola le ho bokella matšoao a optical. Li-splitter tsa fiber li lumella marang-rang a PON ho sebeletsa ba ngolisitseng ba bangata ka fiber e le 'ngoe ntle le tlhoko ea ho kenya likhoele tse arohaneng lipakeng tsa hub le mosebelisi oa ho qetela.

Joalo ka ha lebitso le fana ka maikutlo, marang-rang a PON ha a kenyelle lisebelisoa tsa ho chencha ka enjene le ho arolelana likhoele tsa fiber bakeng sa likarolo tsa marang-rang. Thepa e sebetsang e hlokahala feela mohloling le ho amohela lipheletsong tsa lets'oao.

Ka marang-rang a tloaelehileng a PON, sekhetho sa PLC ke sona se ka sehloohong. Lipompo tsa fiber optic li kopanya mats'oao a mangata a optical ho etsa tlhahiso e le 'ngoe, kapa lipompo tsa fiber optic li nka karolo e le 'ngoe ea optical ebe li e abela linthong tse ngata tse hlahisoang ke motho ka mong. Lipompo tsena tsa PON li fetisoa ka litsela tse peli. Ho hlakisa, mats'oao a fiber optic a ka romeloa tlase ho tloha ofising e bohareng ho ea phatlalatsoa ho bohle ba ngolisitseng. Lipontšo tse tsoang ho ba ngolisitseng li ka romelloa holimo le ho kopanngoa ho ba fiber e le 'ngoe ho buisana le ofisi e bohareng.

AON vs PON Networks: Liphapang le Likhetho

Marang-rang a PON le AON a theha mokokotlo oa fiber optic oa sistimi ea FTTH, e lumellang batho le likhoebo ho fihlella Marang-rang. Pele u khetha PON kapa AON, ke habohlokoa ho utloisisa phapang pakeng tsa bona.

Kabo ea Letšoao

Ha ho tluoa ho marang-rang a AON le a PON, phapang e kholo pakeng tsa bona ke tsela eo lets'oao la optical le abeloang ka eona ho moreki e mong le e mong tsamaisong ea FTTH. Lenaneong la AON, ba ngolisitseng ba fane ka lithupa tsa fiber, tse ba lumellang hore ba be le monyetla oa ho fumana marang-rang a tšoanang, ho e-na le ho arolelana. Marang-rang a PON, ba ngolisitseng ba arolelana karolo e 'ngoe ea fiber bundle ea marang-rang ho PON. Ka lebaka leo, batho ba sebelisang PON ba ka boela ba fumana hore tsamaiso ea bona e lieha hobane basebelisi bohle ba arolelana bandwidth e tšoanang. Haeba bothata bo hlaha ka har'a sistimi ea PON, ho ka ba thata ho fumana mohloli oa bothata.

Litšenyehelo

Litšenyehelo tse kholo ka ho fetisisa tse tsoelang pele marang-rang ke litšenyehelo tsa lisebelisoa tsa motlakase le tlhokomelo. PON e sebelisa lisebelisoa tse sa sebetseng tse hlokang tlhokomelo e fokolang 'me ha ho na motlakase ho feta marang-rang a AON, e leng marang-rang a sebetsang. Kahoo PON e theko e tlase ho feta AON.

Sebaka sa Tšireletso le Likopo

AON e ka nka sebaka sa bohole ba lik'hilomithara tse 90, athe PON hangata e lekantsoe ke likhoele tsa fiber optic tse bolelele ba lik'hilomithara tse 20. Sena se bolela hore basebelisi ba PON ba tlameha ho ba haufi le sebaka se qalang.

Ho feta moo, haeba e amahanngoa le ts'ebeliso kapa ts'ebeletso e itseng, lintlha tse ling tse 'maloa li hloka ho nahanoa. Mohlala, haeba lits'ebeletso tsa RF le livideo li tla romelloa, joale PON hangata ke eona feela tharollo e sebetsang. Leha ho le joalo, haeba litšebeletso tsohle li thehiloe Internet Protocol, joale PON kapa AON e ka ba tse loketseng. Haeba maeto a malelele a ameha mme ho fana ka matla le pholiso ho likarolo tse sebetsang tšimong ho ka ba bothata, joale PON e ka ba khetho e ntle ka ho fetisisa. Kapa, ​​​​haeba moreki ea reretsoeng ke oa khoebo kapa morero o kenyelletsa lihlopha tse ngata tsa bolulo, joale marang-rang a AON a ka ba a loketseng haholoanyane.

AON vs. PON Networks: U khetha FTTH efe?

Ha u khetha pakeng tsa PON kapa AON, ke habohlokoa ho nahana ka hore na ke litšebeletso life tse tla fanoa holim'a marang-rang, topology ea kakaretso ea marang-rang, le hore na bareki ba ka sehloohong ke bo-mang. Basebelisi ba bangata ba kentse motsoako oa marang-rang ka bobeli maemong a fapaneng. Leha ho le joalo, ha tlhokahalo ea ho sebelisana ha marang-rang le scalability e ntse e hōla, meralo ea marang-rang e atisa ho lumella fiber leha e le efe hore e sebelisoe ka mokhoa o fapaneng ho likopo tsa PON kapa AON ho finyella litlhoko tsa litlhoko tsa nakong e tlang.
