PON thev naus laus zis tau dhau los ua cov thev naus laus zis thev naus laus zis rau hauv tsev broadband, thiab nws kuj tau nce ntxiv rau kev lag luam xauj cov kab. Tsis tas li ntawd, vim nws qhov yooj yim ob-theem tag nrho-optical architecture, PON kuj tau dhau los ua ntau dua thiab dav siv hauv chaw ua haujlwm thiab kev tswj hwm kev lag luam.
Nrog rau cov ntawv thov chaw ua si uas tshwm sim sawv cev los ntawm kev sib tham video siab, kev ruaj ntseg ntse, chaw ua haujlwm hauv xov tooj, thiab qis-latency industrial ntau lawm tswj, cov neeg siv tau nce zuj zus thov rau high-bandwidth thiab low-latency PON thev naus laus zis, thiab PON thev naus laus zis tau hloov kho dua tshiab. Rov ua dua tshiab. Tam sim no, cov tswv lag luam tseem ceeb hauv tsev tau hloov kho GPON rau 10G PON thev naus laus zis kom ua tau raws li kev thov bandwidth siab. Txawm li cas los xij, kev lag luam tseem tab tom tham txog yuav ua li cas kom tau raws li cov kev xav tau ntawm cov teeb meem qis qis xws li tsoomfwv qib siab thiab cov neeg siv khoom lag luam thiab kev tswj hwm kev lag luam.
Tsawg-latency 10G PON daws. Raws li pom hauv daim duab hauv qab no, GPON & 10G PON Combo PON yog siv rau ntawmOLTsab, thiab covONUyog siv rau ntawmONUsab. Qhov kev daws teeb meem no txav ntau thiab qhov rais tswj thiab tswj kev ua haujlwm los ntawm 10G PON channel mus rau GPON channel. 10GPON channel ncua yuav raug txo kom tsawg dua 100 microseconds.
Cov tshuaj no tuaj yeem siv ncaj qha rau Combo PONOLTcov khoom siv uas tau siv dav dav, thiab ODN network kuj tseem tuaj yeem hloov pauv, yog li nws muaj txiaj ntsig zoo. Kev taw qhia txog qhov qis-latencyONUtuaj yeem pab cov neeg ua haujlwm sai sai muab cov kev pabcuam latency tsawg.
Qhov qis-latency PON tuaj yeem ua tau raws li qhov xav tau ntawm cov xwm txheej hauv qab no.
(1) Kev lag luam leased line: Raws li 10G PON muab cov lag luam nrog cov kab loj loj xauj, qhov ncua sij hawm ntxiv yog txo los ntawm milliseconds mus rau microseconds kom ua tiav "cov kab xauj zoo heev".
(2) Muaj chaw ua si: Hauv chaw ua si, paub txog txhua qhov chaw ua si ntsuab ntawm fiber ntau rau-tshuab, fiber ntau-rau-lub rooj sib tham, thiab fiber-rau-chaw ua haujlwm. Tsawg-latency PON daws qhov teeb meem qeeb ntawm kev lag luam PON thiab tuaj yeem ua tau raws li qhov xav tau qis-latency ntawm kev lag luam tswj.
