GPON

GPON yog dab tsi?

GPON (Gigabit-Capable PON) yog lub tshuab ua haujlwm siab Passive Optical Network (PON) raws li tus qauv ITU-T G.984.x. Nrog nws qhov zoo ntawm kev ua haujlwm siab bandwidth, kev ua haujlwm siab, kev pabcuam loj thiab cov neeg siv kev sib tw nplua nuj, nws tau dhau los ua cov thev naus laus zis zoo tshaj plaws rau cov neeg ua haujlwm feem ntau kom paub txog kev siv dav dav thiab kev hloov pauv ntawm cov kev pabcuam hauv network.

Siab bandwidth

GPON muaj tus nqi txog li 2.5 Gbps, uas tuaj yeem ua tau raws li qhov kev thov loj hlob rau cov bandwidth siab nyob rau yav tom ntej. Nyob rau tib lub sijhawm, nws cov yam ntxwv asymmetric zoo dua rau kev ua lag luam broadband cov ntaub ntawv.

Kev pabcuam puv ntoob

GPON tuaj yeem nqa ATM hlwb thiab / lossis GEM thav duab tib lub sijhawm, thiab muaj peev xwm muab cov kev pabcuam zoo, txhawb QoS lav thiab kev pabcuam puv ntoob. Qhov no ua rau GPON nqa ntau yam kev pabcuam xws li lub suab, PDH, thiab Ethernet.

Txhawb TDM cov kev pabcuam

Txij li GPON TC ncej ntev yog 125 μs, nws tuaj yeem txhawb nqa TDM cov kev pabcuam ncaj qha. Cov kev pabcuam TDM tseem tuaj yeem ua rau hauv lub tshuab ATM kom muab kev sib kis ntawm lub sijhawm nrog QoS lav.

Kev siv dav dav

Xws li FTTH (fiber rau hauv tsev), FTTB (fiber rau lub tsev), FTTC (fiber rau curb), FTTM (fiber rau ntau lub tsev nyob) thiab lwm yam kev nkag tau scenarios.
