GPON Internet ke eng?

GPON Internet ke theknoloji ea phetiso ea data e optical e u lumellang hore u hokahane le ba ngolisitseng Marang-rang ka lebelo le phahameng le ts'epahalo. Sehloohong sena re tla u bolella hore na GPON Internet ke eng, e sebetsa joang, e na le melemo efe le hore na u ka e hokahanya joang.

GPON Internet ke eng?

GPON (Gigabit Passive Optical Network) ke marang-rang a marang-rang a marang-rang a sebelisang lisebelisoa tsa optical ho fetisetsa data pakeng tsa ofisi e bohareng (OLT) le lisebelisoa tsa ba ngolisitseng (ONT). GPON Internet e bua ka maemo a ITU-T G.984, a hlalosang mekhahlelo le litšobotsi tsa marang-rang a joalo.

GPON inthaneteng e fana ka lebelo le phahameng la phetisetso ea data - ho fihla ho 2,5 Gbit/s ho tloha ho OLT ho ea ho ONT le ho fihla ho 1,25 Gbit/s ka lehlakoreng le leng. Ntle le moo, GPON Internet e ts'ehetsa mefuta e fapaneng ea sephethephethe, joalo ka Marang-rang, mohala, thelevishene, leihlo la video le tse ling.

GPON Internet e sebetsa joang?

GPON Internet e sebetsa ho latela molao-motheo oa karohano ea nako (TDM) le karohano ea maqhubu a maqhubu (WDM). TDM e bolela hore data e tsoang ho ba ngolisitseng ba fapaneng e fetisetsoa holim'a fiber e tšoanang ea optical ka linako tse fapaneng, 'me WDM e bolela hore data e tsoang mefuteng e fapaneng ea sephethephethe e fetisoa ka nako e fapaneng ea wavelengths.

GPON Internet e na le lintlha tse tharo tsa mantlha:

• OLT (Optical Line Terminal) ke sesebelisoa se bohareng se hokahanyang le mofani oa Inthanete 'me se laola phetiso ea data pakeng tsa optical fibers le lisebelisoa tsa ba ngolisitseng.
• ONT (Optical Network Terminal) ke sesebelisoa sa ba ngolisitseng se hokahanyang le fiber ea optical le ho fetola matšoao a optical hore e be lipontšo tsa motlakase, hape e fana ka lihokelo tsa ho hokahanya lisebelisoa tse fapaneng tse kang komporo, mohala, TV le tse ling.
• ODN (Optical Distribution Network) ke marang-rang a optical fiber a kopanyang OLT le ONT. ODN e kanna ea kenyelletsa likarolo tse fapaneng tsa mahlo tse sa sebetseng joalo ka li-splitter, likhokahano, liadapter le tse ling.

Ka mokhoa o hlophisitsoeng, Marang-rang a GPON a ka emeloa ka tsela e latelang:

Melemo ea GPON

Ho hokela Marang-rang ka GPON ho na le melemo e mengata ho feta mahlale a mang a kang ADSL, VDSL, Ethernet kapa DOCSIS. Tse ling tsa tsona ke tsena:

• Lebelo le phahameng. GPON e u lumella ho fumana lebelo la Marang-rang le fihlang ho 2,5 Gbit/s, e leng makhetlo a 'maloa ho feta lebelo la mahlale a mang. Sena se bolela hore o ka shebella livideo tsa litlhaloso tse phahameng, oa bapala lipapali tsa inthaneteng, oa khoasolla lifaele tse kholo le ho sebelisa lisebelisoa tse ling tsa Marang-rang ntle le tšitiso kapa tšitiso.
• Ho tšepahala. GPON e sebelisa thapo ea optical e sa ts'oaroang ke tšitiso ea motlakase, ho bola, ho chesa ho feta tekano kapa tšenyo ea mochini. Ho phaella moo, marang-rang a passive optical ha a na lintho tse sebetsang tse ka hlōlehang kapa tsa hloka ho nkeloa sebaka. Sena se tiisa botsitso le boleng ba puisano maemong afe kapa afe.
• Moruo. GPON e u lumella ho fokotsa litšenyehelo tsa ho hokahanya le ho boloka marang-rang, kaha ha e hloke lisebelisoa tse eketsehileng, motlakase kapa basebetsi. Ho phaella moo, GPON e u lumella ho fumana litšebeletso tse 'maloa tsa puisano ka mohala o le mong, e leng ho fokotsang palo ea lithapo le likoti ka foleteng.
• Ho feto-fetoha ha maemo. GPON e ts'ehetsa liprothokholo tse fapaneng le litekanyetso tsa phetiso ea data, joalo ka IP, ATM, Ethernet, TDM le tse ling. Sena se o nolofalletsa ho hokahanya lisebelisoa leha e le life ho marang-rang le ho sebelisa litšebeletso leha e le life tsa puisano, tse kang Inthanete, thelevishene, mohala, ho shebella video, intercom le tse ling.

Mathata a GPON

• Li-bandwidth tse fokolang. Le hoja GPON e fana ka lebelo le phahameng la Inthanete, ha e tiisetsoe, empa e itšetlehile ka palo ea ba ngolisitseng ba hokahaneng le sesepa se le seng sa optical. Haeba ho na le ba ngolisitseng ba bangata, marang-rang a marang-rang a tla aroloa pakeng tsa bona mme lebelo la Inthanete le ka fokotseha. Ka lebaka leo, ke habohlokoa ho khetha mofani ea laolang palo ea ba ngolisitseng ka ho arola le ho fana ka bandwidth e lekaneng bakeng sa mofani e mong le e mong.
• Tšireletseho e tlaase. GPON e sebelisa thapo e le 'ngoe ea optical ho fetisetsa data ho tsoa ho mofani ho ba ngolisitseng ba hokahaneng le sekhechana se le seng. Sena se bolela hore bohle ba ngolisitseng ba fumana letšoao le tšoanang, le ka amoheloang kapa la fetoloa ke bahlaseli. Ka hona, ho bohlokoa ho khetha mofani ea sebelisang mekhoa e fapaneng ea ho kenyelletsa le ho netefatsa ho sireletsa data ea hau ho tsoa phihlellong e sa lumelloeng.
• Theko e phahameng. GPON e hloka ho kenya lisebelisoa tse khethehileng, tse theko e boima haholo. Sena se sebetsa ho OLT ka bobeli e fumanehang ho mofani oa thepa le ONT e fumanehang foleteng ea ba ngolisitseng. Ho feta moo, litšenyehelo tsa cable ea optical li boetse li phahame ho feta theko ea mohala oa koporo. Ka hona, litefiso tsa ho hokela GPON li ka ba holimo ho feta tsa ho hokahanya le mahlale a mang.
