A OLT yog dab tsi? Nkag siab nws qhov tseem ceeb ntawm lub luag hauj lwm hauv fiber ntau lub network
Nyob rau hauv niaj hnub no kev ceev ceev Internet Era, Fiber Optic network tau ua dhau los ua tus caj qaum ntawm kev sib txuas lus ntxiv. Ntawm lub plawv ntawm fiber ntau kev siv cov neeg tseem ceeb ntawm cov khoom tseem ceeb: The olt (kho kho kab xaus chaw). Cov ntawv no tshawb nrhiav dab tsi olt yog, nws ua haujlwm li cas, thiab vim li cas nws tsis tseem ceeb hauv fiber network architecture.
Txhais lub olt: Cov Ntsiab Tseem Ceeb
Ib qho olt (kho qhov muag lub davhlau ya nyob twg) ua haujlwm ua tus muab kev pab Feem ntau nyob hauv tus kws khomob lub chaw haujlwm chaw ua haujlwm lossis cov olt ua raws li lub rooj vag ntawm cov neeg muab kev pab cuam uas ncav cuag cov neeg siv kawg.
Xav txog cov olt uas yog "lub hlwb" ntawm cov ntaub ntawv ntws ntawm cov neeg muab kev pabcuam ntawm lub network thiab cov khoom siv cov khoom siv los ntawm cov khoom siv kho kho.
Cov haujlwm tseem ceeb ntawm OLT hauv fiber networkts
1. Network cov tsheb sib sau ua ke thiab xa tawm
Tus olt ua raws li kev sib sau ua ke uas txuas tus muab kev pabcuam tus kws khomob rau ntau tus neeg siv kawg. Los ntawm kev kho qhov muag kho qhov muag, ib qho OLT tuaj yeem pab ntau pua ntawm cov leeg tuaj yeem pab ntau yam-rau-muaj cov cuab yeej siv hluav taws xob), tsim kom muaj kev siv fiber ntau.
2. Kev Nkag Nkag Nkag Nkag Siab thiab Kev Ua
OLT ua Bidirectional teeb liab hloov dua siab tshiab:
Nqes hav: Hloov Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Los Ntawm Cov Tub Ntxhais Network rau Optical Cov Duab Rau Kev Hloov Mus Rau Cov Neeg Siv
Ntws los: Hloov kho qhov muag ntawm cov neeg siv rov qab rau hluav taws xob cov cim rau cov ntsiab lus tseem ceeb
3. Lub zog dynwidth faib
Niaj hnub OLTS niaj hnub feature dynamic bandwidth faib (DBA) algorithms uas:
Kev Tshaj Tawm Muaj Bandromed muaj bandomwidth ntawm cov neeg siv cov lus txuas nrog
Ua Ntej Cov Tsheb Raws Li Cov Ntawv Cog Lus Theem
Xyuas kom zoo ntawm kev pabcuam (qos) rau latency-rhiab applics zoo li VoIP thiab video streaming
4. Network tswj thiab tshuaj xyuas
OLTS muab kev tswj hwm kev tswj hwm uas muaj peev xwm ua rau cov neeg ua haujlwm rau:
Saib xyuas lub sijhawm tiag tiag network kev ua haujlwm
Nrawm Nruag thiab Teeb Meem Teeb Meem
Remotely Configure Onu Devices
Sau cov ntaub ntawv siv rau kev them nqi thiab kev npaj muaj peev xwm
Raug PCT Daim Ntawv Thov
Ftth (Fiber rau hauv tsev): Xa cov khoom siv ultra-high-ceev broadband rau cov neeg siv nyob
Kev Lag Luam Txuas: Muab cov kab kom tau cov kab rau cov lag luam
5grmaultaul: Txuas 5g puag ncig rau cov tub ntxhais network
Ntse Hauv Nroog Infrasure: Kev txhawb nqa loj iot ntaus ntawv txuas
Cable TV Overlay: Xa IPTV thiab cov kev pabcuam video
Olt Technology Evolution
OLT Technology txuas ntxiv mus ua ntej kom tau raws li cov kev xav tau:
Siab dua: Tsiv teb tsaws los ntawm gpon (2.5g downstream) rau xgs-pon (10g symmetric) thiab ng-pon2 (40g)
Virtualization: Huab-haiv volt (virtual OLT) kev siv
Txhim Kho Kev Ruaj Ntseg: Advanced encryption thiab kev txheeb xyuas kev txheeb xyuas cov txheej txheem
Ai Kev Sib Tw: Kev kwv yees txij nkawm thiab kev ua kom zoo ntawm tus kheej
SDN Sib Tw: Software software txhais tau tias muaj peev xwm ua tau rau cov kev ua tiav
Tag
Raws li lub nruab nrab ntawm cov leeg hlwb ntawm cov kev siv fiber ntau, olts ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab network kev ua haujlwm thiab kev ntseeg tau. Nrog kev tawm thev naus laus zis zoo li 5g, 8k video, vr \/ ar, thiab is taws nem, olts ntsib muaj peev xwm ntau dua, qis dua kev ua haujlwm.
Kev nkag siab OLT thev naus laus zis yuav pab cov phiaj xwm kev ua lag luam zoo, pab cov neeg ua haujlwm kom txaus siab rau cov neeg siv khoom lag luam kom zoo rau lawv qhov kev sib txuas nrawm. Raws li peb tau txav mus rau qhov kho qhov muag tag nrho, cov tes hauj lwm ntse, OLT thev naus laus zis yuav txuas ntxiv mus Txhawb peb cov kev nce qib siab ntxiv.
