Tshuab fiber ntau optic tau hloov kho txoj kev peb sib txuas lus, kev ntseeg tau, thiab bandwidth . ntawm qhov kev hloov pauv ntawm qhov kev hloov pauv noKab kho qhov muag kab (OLT), ib qho kev tiv thaiv tseem ceeb hauv passive kho qhov muag tes hauj lwm (Pon) .} Tab sis dab tsi yog nws thiaj li tseem ceeb hauv xov tooj cua niaj hnub?
Hauv no blog ncej, peb yuav tshawb txog lub luag haujlwm ntawm OLTS, thiab yog vim li cas lawv thiaj li yog lub rooj vag rau tom ntej no optic tes hauj lwm.
A OLT yog dab tsi?
IbKab kho qhov muag kab (OLT)yog ib qho cuab yeej uas ua haujlwm ua tus muab kev pabcuam rau qhov kawg ntawm kev siv kho qhov muag (Pon) . nws txuas rau ntauKho qhov chaw siv kho qhov muag (onus)lossisLub Chaw Haujlwm Network Terminals (OTS)ntawm tus neeg siv khoom thaj chaw, ua kom cov ntaub ntawv ceev, lub suab, thiab video kis tshaj tawm cov khoom siv hluav taws xob fiber ntau {}}
Cov haujlwm tseem ceeb ntawm ALT:
Daim phiajcim hloov dua siab tshiab- Hloov cov hluav taws xob cov cim los ntawm cov neeg muab kev pabcuam hauv lub network rau cov cim kho qhov muag rau cov khoom siv hluav taws xob rau cov khoom siv fiber ntau {}}
Tswj Xyuas Tsheb- tswj cov txheej txheem ntws los thiab cov txheej txheem ntws ntws ntawm lub chaw ua haujlwm nruab nrab thiab cov neeg siv kawg .
Bandwidth faib- Dynamically faib bandwidth txuas rau onus / onts rau cov ntaub ntawv hloov pauv tau zoo .
Kev Ruaj Ntseg & Kev Pom Zoo- Saib xyuas kev sib txuas lus zoo los ntawm cov ntaub ntawv encrypting thiab qhia txog cov khoom siv uas sib txuas .
A OLT ua haujlwm li cas?
Ib txwm raug Pon Architecture muaj:
OLT (ntawm ISP lub chaw ua haujlwm nruab nrab)
Khoteical Splitter (Passive ntaus ntawv faib cov cim)
Onu / ont (ntawm tus neeg siv qhov chaw nyob)
Cov ntaub ntawv ntws hauv ib Pon:
Nqes hav sib kis- Cov olt tshaj tawm cov ntaub ntawv rau tag nrho cov onus ntawm ib qho software fiber {}} Txhua cov ntaub ntawv nkag rau nws.
Ncig xa hluav taws xob- onus xa cov ntaub ntawv rov qab mus rau hauv OLT hauv cov sijhawm tsim qauv hauv lub sijhawm, tiv thaiv kev sib tsoo teeb liab {}}
Notaw tes-rau-muaj-multipointCov qauv ua rau cov tub ua tau zoo, txo cov nqi tsev hauv tsev thaum xa khoom siv nrawm {}}
Vim li cas OLTS yog lub neej yav tom ntej ntawm kev sib txuas lus fiber ntau
Kev Tawm Tsam Loj- Txhawb cov gigabit thiab txawm tias 10g pon (xgs-pon) thev naus laus zis, rooj sib tham loj bandwidth xav.
Kev loj- ib qho OLT tuaj yeem pab ntau pua tus neeg siv, ua rau nws zoo tagnrho rau ISP nthuav lawv cov tes hauj lwm fiber network {}}
Zog Efficiency- tsis zoo li cov khoom tooj liab zoo nkauj, cov roj nrog olts haus cawv tsawg dua .
Yav Tom Ntej-Ntawv Pov Thawj Txheej Txheem- OLTS tau tshaj tawm nrog kev tawm ntawm cov thev naus laus zis xws li 5g backennaul thiab io network.
