Technology GPON - zexa ezintsha ngeengcingo

Le GPON-technology ngokwangoku yeyona mihla, ngempumelelo yaye phambili-akukhangela kwintsapho ebanzi lothungelwano fibre-optic kwisixando sokwenziwa. Ngokusekelwe kule yangoku kwiminyaka yakutshanje, imigangatho yaseYurophu, inika abanini zikamabonakude cable kunye nabaniki-nkonzo intanethi izisombululo kwicandelo-high speed ukufikelela kwi-World Wide Web, isiginali ezizinzileyo kunye zibubunjani obubodwa lwemifanekiso kamabonakude. GPON-technology nayo ibonelela imali ebonakalayo kakhulu ifayibha woqondo ngokusebenzisa umthi yethopholoji womnatha izakhiwo, kwaye nokuthembeka uphakamileyo kuphunyezwa ngokuthi imiba eyayizalwa kwisixando sokwenziwa. Kodwa mhlawumbi uncedo engundoqo ezintsha zonxibelelwano iphezulu-isantya "imayela yokugqibela".

GPON-technology ixhasa ubuchule mihla le kwicandelo kwamaza multiplexing, nto leyo evumela ukuba ukwandisa kakhulu umthamo womnatha ngaphandle kuphuculo iziseko zazo intambo. Umthi yethopholoji inika amathuba olukhulu lolawulo bhetyebhetye iinkonzo zabaxumi Bandwidth. Ngelo ubuchwepheshe GPON efanayo izinga data sezingeni eliphezulu elinika elubala zothutho ngeenkonzo ezahlukeneyo: SDH, Ethernet, ATM, njl

Ngaloo ndlela, izinto ezininzi lothungelwano fibre-optic eyimpumelelo eziliqela iimpawu ezizodwa zigqitywa eziluncedo obu bugcisa ngaphezu kwezinye lwazi bolwakhiwo lwempahla thethwano lomnxeba, ngakumbi ngokuphathelele kwi-high speed "imayela yokugqibela". Oku kungenxa ukusasazeka ngokukhawuleza ezintsha kulwakhiwo-high speed networks multiservice isixeko fibre-optic. Yintoni GPON-technology, yaye yintoni umongo wayo?

Iyodwa, kulula ukulwenza, zonke ezikrelekrele. Esiludumbo umboneleli engundoqo, ngokubonelela amanqaku-high speed uqhagamshelo lomqolo enxulumene kwinethiwekhi rhumela woqondo angenzi a ukwakhiwa emthini. Oku kudala iindawo ezikhethekileyo eliphakathi kubamba gqiphu compact kwisixando (gqiphu) uhlobo optical. passivity wabo kuthetha ukuba ngokupheleleyo abawadingi ukutya okanye inkonzo.

Le GPON-izixhobo, nakwezithiwe gqiphu, iquka hardware kunye ngasesitishini software kunye umsebenzisi multi-service ezinjengeetheminali. Kwaye omnye iqonga basenokugqithisela ulwazi inani izixhobo isikhokhelo, leyo ikuvumela ukuba ukwazi ukuqhagamshela ku amandla mali kunye nesantya transceiver le iintsimbi. Zizo zonke izixhobo mihla ikuvumela ukuba ngokukhawuleza kunye neendleko-ngempumelelo nibafaka inethiwekhi fibre-optic zezenzi, nokuhlaziywa nakubugcisa intambo.

Yintoni umdla kukuba uthungelwano kwisixando ifayibha optic hayi wayila kweenkqubo yanamhlanje. Uphuhliso obu bugcisa ukudluliselwa kwaqala yee-, enzulwini labs Telecom yaseBritani. Kwiminyaka embalwa kamva izilingo uvavanyo lokuqala lwenziwa emva kokuqalisa uphuhliso, apho yazinyaswa ngomabonakude ezininzi ezaziwayo-kakuhle yaseYurophu. Kwixa elizayo, lo bugcisa sele kudlule zigaba ezininzi zokuphucula kunye maxesha. Uthungelwano lokuqala kwisixando yale hlobo waba umthamo we 155 Mbit / s. Noko ke, ngelo xesha lo ngokwaneleyo. Kwaye ngoku, ngenxa inkqubela ngokukhawuleza i Internet and digital TV, ubuchwepheshe siqinisekiswa ukuba ethandwayo ngokwenene.
