La 30 Phupu 2024

Lefatše la hona joale le itšetlehile haholo ka phapanyetsano e tšepahalang le e potlakileng ea boitsebiso. Ka nepo, litlhoko tse ntseng li phahama tsa litefiso tse kholo tsa data li fetisitse matla a sistimi ea hajoale. Litheknoloji tsa morao-rao, tsa passive optical network (PON) e se e le tsona meralo ea mantlha ea ho fihlela kholo ea tlhokahalo ea basebelisi ba ho qetela. Kaha PON e ntse e tsoela pele ho fetohela ho sekhahla sa data se fetang 100 Gbps, mahlale a PON a ipapisitseng le ts'ebetso ea ho feto-fetoha ha maemo a matla a qobelletsoe ho amohela litlhoko tse ntseng li hola ka potlako. Haholo-holo, theknoloji ea PON e momahaneng e fetotse tsela eo batho ba fetisang data ka eona marang-rang a fiber-optic. Ka ho sebelisa mekhoa e tsoetseng pele ea ho feto-fetoha le maemo le ts'ebetso ea mats'oao a dijithale, PON e ts'oanang e ekelitse bokhoni le phihlello ea lits'ebetso tsa PON. Seo se nolofalelitse mehala ea puisanolik'hamphani ho fana ka marang-rang a lebelo le phahameng le lits'ebeletso tse ling tsa data ho ba ngolisitseng ba bangata ka ts'epo le ts'ebetso e ntlafalitsoeng.

 Lisebelisoa tsa theknoloji e lumellanang ea PON

Theknoloji e kopanetsoeng ea PON e na le lisebelisoa tse 'maloa tse ka khonehang ho pholletsa le indasteri e fapaneng. Tse ling tsa lisebelisoa tsa bohlokoa li kenyelletsa:

Indasteri ea Likhokahano

Lihlahisoa tse lumellanang tsa theknoloji ea PON tse kangTsohle Dielectric Self-Supporting Cable(ADSS),optical fatše terata(OPGW), mohala oa pigtail le cable ea optic e ka sebelisoa indastering ea likhokahano ho fana ka lits'ebeletso tse pharalletseng tsa lebelo le phahameng ho bareki ba bolulo le ba khoebo. Ka ho sebelisa li-optics tse lumellanang, basebelisi ba lithelefono ba ka finyella bokhoni bo phahameng ba marang-rang le ho fihlella nako e telele, ba fana ka lebelo le potlakileng la marang-rang le ho tšehetsa lits'ebetso tse lapileng li-bandwidth tse kang ho phallela video, lits'ebeletso tsa maru, le liphihlelo tsa sebele.

Litsi tsa Boitsebiso

Lihlahisoa tse lumellanang tsa PON tse kang optical ground wire (OPGW), pigtail cable, le optic cable li ka sebelisoa litsing tsa data ho etsa hore ho be le khokahanyo e sebetsang hantle le e tsitsitseng. Mekhatlo e ka ntlafatsa bokhoni ba phetisetso ea data ka ho kopanya PON e ts'oanang ho meralo ea setsi sa data, ho fokotsa latency, le ho ntlafatsa ts'ebetso ea marang-rang ka kakaretso. Seo se ka lebisa taolong e betere ea data, phihlello e potlakileng ea tlhaiso-leseling, le ts'ehetso ea mahlale a ntseng a hlaha joalo ka ho ithuta ka mochini le bohlale ba maiketsetso.

Smart Cities

Tšebeliso e 'ngoe e ts'episang ea theknoloji ea PON e lumellanang ke ho nts'etsapele litoropo tse bohlale. Ka ho sebelisa marang-rang a ts'oanang a PON, bomasepala ba ka theha meaho e matla le e feto-fetohang ho ts'ehetsa mats'oao a mangata a macha a toropo, joalo ka mabone a bohlale, taolo ea sephethephethe, tlhahlobo ea tikoloho le lits'ebetso tsa polokeho ea sechaba. Marang-rang ana a nolofalletsa ho arolelana lintlha, ho hlahloba nako ea sebele, le khokahanyo e ntlafetseng, ho kenya letsoho ntlafatsong e sebetsang hantle le e tsitsitseng libakeng tsa litoropo.

Litšebeletso tse ntlafetseng tsa Broadband

Theknoloji e kopanetsoeng ea PON e ka fana ka litšebeletso tse ntlafalitsoeng tsa Broadband ho basebelisi ba ho qetela. Ka ho sebelisa mekhoa e lumellanang ea phetisetso, marang-rang a PON a ka ts'ehetsa litefiso tse phahameng tsa data le lits'ebetso tse matla tsa bandwidth, joalo ka ho phallela ha video ea ultra-HD, 'nete ea nnete, le papali ea inthaneteng. Seo se nolofalletsa bafani ba litšebeletso ho fa ba ngolisitseng phihlelo e phahameng, ho finyella tlhokahalo e ntseng e eketseha ea khokahanyo ea inthanete e potlakileng.

E Felletseng-Mobile Access

Theknoloji e lumellanang ea PON e nolofalletsa ho kopana ha marang-rang a tsitsitseng le a mohala. Basebelisi ba ka fana ka khokahanyo e se nang moeli bakeng sa marang-rang a marang-rang a tsitsitseng le a hlahang5Glits'ebeletso tsa mobileka ho kopanya li-optics tse lumellanang le lisebelisoa tse teng tsa PON. Khokahano ena e nolofatsa meralo ea marang-rang 'me e bula tsela bakeng sa bongata ba lits'ebeletso le liphihlelo tse fapaneng bakeng sa basebelisi ba ho qetela.

Network Slicing le Virtualization

Tšebeliso e 'ngoe ea bohlokoa ea theknoloji ea PON e tsitsitseng ke ho khaola marang-rang le tšehetso ea virtualization. Bokhoni bona bo lumella basebelisi ho arola lisebelisoa tsa PON tsa 'mele ho li-PON tse ngata, e' ngoe le e 'ngoe e etselitsoe litšebeletso tse itseng kapa likarolo tsa bareki. Ka ho fana ka lisebelisoa ka matla le ho ikamahanya le litlhoko tse fetohang, marang-rang a kopaneng a PON a ka ntlafatsa ts'ebetso, a ntlafatsa maemo, 'me a sebelisa lits'ebeletso tse fapaneng ka nepo.

Melemo ea theknoloji ea PON

Bonolo ba tlhokomelo

PON e nkela sebaka sa marang-rang a koporo a kotsing ea lerata le tšitiso ea motlakase. E le khetho, marang-rang a PON ha a tšoenyehe ke tšitiso e joalo 'me a ka boloka botšepehi ba matšoao ka har'a sebaka se reriloeng. Kaha ho bonolo hore motho a shebe le ho tseba mehloli ea tahlehelo ho PON, marang-rang ana ho ba bonolo ho a rarolla le ho a hlokomela.

Bokhoni ba ho ts'ehetsa litefiso tsa data tsa symmetrical le asymmetrical

Monyetla o mong oa bohlokoa oa theknoloji ea PON e momahaneng ke bokhoni ba eona ba ho ts'ehetsa litefiso tsa data tsa symmetrical le asymmetrical, e lumellang hore ho be le phepelo e bonolo meahong e fapaneng ea marang-rang. Ho feta moo, ho lemoha ka mokhoa o ts'oanang ho thusa tsamaiso ho lefella ho senyeha ha lisebelisoa tsa fiber, e leng se bakang boleng bo botle ba matšoao le lebelo le phahameng la phetisetso.

Theknoloji e kopanetsoeng ea PON e fetola tsela eo marang-rang a phihlello ea mahlo a entsoeng le ho sebelisoa ka eona. Lisebelisoa tsa eona tse ngata li nchafatsa indasteri ea likhokahano, e fana ka ts'ebetso e ntlafalitsoeng le ho hola. Ts'ebeliso ea theknoloji ea PON e momahaneng e akaretsa likarolo tse fapaneng, ho kenyeletsoa likhokahano tsa mehala, likhokahano tsa likhoebo le lits'ebeletso tsa marang-rang tsa bolulo. Lisebelisoa tsena li totobatsa ho feto-fetoha ha maemo le phello ea theknoloji e tsitsitseng ea PON ho tsamaisang phetoho ea marang-rang a ho fihlella le ho finyella litlhoko tsa khokahanyo ea moloko o latelang. Ha tlhokahalo ea lebelo le phahameng, khokahanyo e tšepahalang e ntse e hola, theknoloji e lumellanang ea PON e lebelletsoe ho bapala karolo ea bohlokoa ho fihlela litlhoko tsena le ho theha bokamoso ba likhokahano tsa marang-rang a optical.
