GPON thekenoloji - brennan mocha oa puisano

The GPON-thekenoloji ke jwale ka ho fetisisa mehleng ea kajeno, le sebetsang hamolemo le pele-sheba ka lelapa ka toka sephara ea etseng letho dinetweke tseo faeba-optic. Thehiloeng morao-rao lilemong tsa morao tjena, melao ea European, ho fana ka kabel a thelevishene lisebelisoa le bafani ba ditshebeletso Internet ho ditharollo atlehe tšimong ea ho fihlella phahameng-lebelo ho World Wide Web, pontšo e tsitsitseng le e boleng ikhethang litšoantšo thelevisheneng. GPON-thekenoloji boetse o fana ka chelete ea bohlokoa haholo ya faeba Optical ka sefate topology mehaho marangrang, le phahameng tšepahala e finyelloa ka branching likarolo etseng letho. Empa mohlomong e Molemo ka sehloohong tsa dipopontshwa tlhaeletsanong ke phahameng ka lebelo "mile qetela".

GPON-thekenoloji tšehetsa mokhoa oa kajeno oa wavelength karohano multiplexing, eo lumella ho haholo eketsa marangrang bokgoni ntle ntlafatsa tsa dibopeho tsa motheo tsa bona kabel. A topology sefate fana le menyetla e metle bakeng sa taolo ya tenyetsehang ditshebeletso kgonothebolo etsetsoang. Ka theknoloji e tšoanang GPON na le reiti ea lekaneng phahameng ya data e fana ka ho sebeletsa pepeneneng ea lipalangoang bakeng sa mefuta e fapaneng ya ditshebeletso: SDH, Ethernet, ATM, joalo-joalo

Kahoo, menyetla e mengata ea etseng letho dinetweke tseo faeba-optic le nomoro ya litšobotsi buka e ikhethang ikemiselitse ke melemo ea ho ea theknoloji ena ba fetang meaho e meng tlhaeletsanong, haholo-holo mabapi le phahameng-lebelo "mile qetela". Sena ke ka ntlha ya go ho ata ka potlako le popontshwa le ka kaho ea phahameng-lebelo faeba-optic dinetweke tseo motse multiservice. ke eng GPON-theknoloji, 'me se le hantle lona?

Ka boeona, ho e bonolo, joaloka tsohle bohlale. E bohareng mofani noute, ho fana ka phahameng ka lebelo le lintlha mokokotlo mabapi amanang ho etseng letho Optical peeletso marangrang a mehaho sefate. Sena se etsa hore e khethehileng nodes lipakeng hore amohela e diseke ee etseng letho splitters (splitters) Optical mofuta. passivity bona ho bolela hore ba ka ho feletseng ha ho hlokahale lijo kapa tšebeletso.

The GPON-thepa, splitters, ho akarelletsa ho selotlolo tšebeletso hardware le seteishene Software sethaleng le mosebedisi boemelong. Le sethaleng 'ngoe ka fetisetsa boitsebiso bo joalo palo a maqheka peeletso, e lumella u ho hokahanya ho ho matla moralo oa tšebeliso ea le lebelo transceiver hardware. The bothe ya thepa ea kajeno lumella u ho ka potlako le ka bolokang tjhelete katleho romela etseng letho faeba-optic marangrang, le ntlafatsa le mehaho kabel.

Se thahasellisang ke hore etseng letho Optical faeba dinetweke tseo ha ho qaptjoa mechine ea tsamaiso ea kajeno. Ntshetsopeleng ya theknoloji ena phetiso ea qala ka eighties, ka bolibeng ba Labs British Telecom. Lilemo tse seng kae hamorao liteko teko pele ba ileng ba tsoa ka mora ho qala ho hōla, e leng ne a e-ba teng ka ho tsebahalang a thelevishene tse ngata tsa Europe. Nakong e tlang, theknoloji ena e fetile mekhahlelo ngata ntlafatso le modernization. Pele etseng letho marangrang a mofuta ona o ne a bokgoni ba 155 Mbit / s. Leha ho le joalo, ka nako eo ena e ne e lekane. Le feela hona joale, ka lebaka la ho tsoela pele ka potlako tsa Internet le ditsitithale TV, theknoloji e ile ea e-hlile o ratoang.
