Nyob rau lub caij nyoog niaj hnub no ntawm kev hloov pauv digital, kev sib txuas tau dhau los ua ib feem tseem ceeb ntawm peb lub neej. Txawm hais tias rau kev lag luam lossis kev siv tus kheej, muaj cov khoom siv network txhim khu kev qha thiab ua tau zoo yog qhov tseem ceeb. EPON (Ethernet Passive Optical Network) thev naus laus zis tau dhau los ua thawj qhov kev xaiv rau kev xa cov ntaub ntawv zoo. Hauv cov blog no, peb yuav tshawb nrhiavEPON OLT(Optical Line Terminal) thiab delve rau hauv nws cov yam ntxwv zoo heev thiab daim ntawv thov.
Cov haujlwm muaj zog ntawm EPON OLT
EPON OLT yog ib lub cuab yeej siv network tshiab uas coj ua ke cov thev naus laus zis siab heev los muab kev sib txuas lus zoo rau kev siv hauv tsev thiab kev lag luam. Tshwj xeeb tshaj yog OLT-E16V, nruab nrog 4 * GE (tooj liab) thiab 4 * SFP qhov chaw sib txuas lus ywj pheej rau uplink, thiab 16 * EPON OLT chaw nres nkoj rau kev sib txuas lus downlink. Cov qauv zoo kawg no ua rau OLT tuaj yeem pab txhawb txog li 1024 ONUs (Optical Network Units) ntawm qhov sib cais ntawm 1:64, ua kom muaj lub network muaj zog rau ntau tus neeg siv.
Compact, yooj yim thiab ntau yam
Ib qho ntawm cov yam ntxwv zoo tshaj plaws ntawm EPON OLT yog nws qhov me me thiab 1U qhov siab 19-nti rack-mount tsim. Qhov no ua rau nws zoo tagnrho rau kev xa mus rau hauv cov chav me me lossis thaj chaw uas muaj qhov chaw khib tsawg. Lub OLT daim ntawv me me, ua ke nrog nws qhov yooj ywm thiab yooj yim ntawm kev xa mus, ua rau nws yog qhov kev xaiv zoo rau ntau yam chaw, suav nrog cov chav nyob, cov lag luam me, thiab cov txheej txheem lag luam.
Kev Ua Tau Zoo Thiab Kev Ua Haujlwm Zoo Tshaj Plaws
EPON OLTLawv paub txog lawv qhov kev ua tau zoo heev, thiab OLT-E16V tsis muaj qhov tshwj xeeb. Nrog nws qhov kev ua tau zoo siab, nws ua kom muaj kev sib txuas ruaj khov thiab txhim khu kev qha rau ntau yam kev siv. Txij li "triple play" cov kev pabcuam (suav nrog lub suab, video thiab cov ntaub ntawv) mus rau VPN kev sib txuas, IP lub koob yees duab saib xyuas, kev teeb tsa LAN hauv tuam txhab thiab ICT daim ntawv thov, EPON OLT tuaj yeem ua txhua yam. Nws lub peev xwm los txhawb ntau yam haujlwm tib lub sijhawm yam tsis muaj kev cuam tshuam rau qhov ceev lossis qhov zoo ntawm lub network yog qhov pov thawj rau nws qhov kev ua haujlwm zoo.
Kev sib txuas ua ke cov tes hauj lwm yav tom ntej uas ruaj khov
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm EPON OLT yog nws lub peev xwm los sib koom ua ke nrog cov khoom siv hauv network uas twb muaj lawm. Qhov kev sib koom ua ke no tso cai rau kev nthuav dav yav tom ntej thiab kev hloov kho yooj yim, ua rau nws yog kev nqis peev mus sij hawm ntev. Raws li peb cov kev xav tau kev sib txuas txuas ntxiv mus thiab loj hlob, EPON OLTs tuaj yeem hloov kho thiab nthuav dav yam tsis muaj kev hloov kho loj hauv cov khoom siv, txuag lub sijhawm thiab cov peev txheej.
xaus lus
Hauv lub ntiaj teb uas kev sib txuas lus tseem ceeb heev, kev muaj lub network infrastructure txhim khu kev qha thiab ua tau zoo yog qhov tseem ceeb heev. EPON OLT, tshwj xeeb tshaj yog OLT-E16V, yog qhov hloov pauv loj hauv qhov no. Nws cov qauv me me tab sis muaj zog, ua ke nrog cov kev xaiv xa tawm yooj yim thiab kev ua tau zoo tshaj plaws, ua rau nws zoo tagnrho rau ntau yam kev siv. Los ntawm kev nqis peev rau hauv EPON OLT, koj tuaj yeem ua kom muaj kev sib txuas lus zoo hnub no thiab tag kis.
Yog li ntawd, txawm tias koj yog tus tswv lag luam me uas xav muab kev pabcuam hauv Is Taws Nem rau cov neeg siv khoom, lossis lub tuam txhab uas tab tom nrhiav kev tsim kho network muaj zog, koj tuaj yeem xav txog EPON OLT ua koj qhov kev daws teeb meem. Txais lub zog ntawm kev sib txuas lus zoo thiab qhib cov cib fim tshiab hauv lub ntiaj teb digital.
