Nrog rau kev txhim kho txuas ntxiv ntawm lub network bandwidth, kev txhim kho txuas ntxiv ntawm cov khoom siv davhlau ya nyob twg, kev sib tham video siab, kev pabcuam huab, huab hwm coj cov ntaub ntawv sib pauv, chaw ua haujlwm txawb, thiab lwm yam, cov tuam txhab ua haujlwm tau zoo dua thiab qhib platform, yog li txhawb kev txawj ntse thiab cov ntaub ntawv chaw ua haujlwm. ntawm kev lag luam, thiab cov kev xav tau rau network bandwidth thiab ceev tau dhau los ua siab dua thiab siab dua.Traditional enterprise thiab campus Lans muaj qhov xav tau ntawm kev hloov kho network thaum ntsib kev sib tw loj ntawm bandwidth los ntawm cov ntawv thov no.
Qhov sib xyaw ua ke ntawm tag nrho cov optical network
POL siv PON thev naus laus zis, Passive Optical Network (PON) yog point-to-multi point (P2MP) Passive Optical Network, uas muaj OLT (LM808E), ODN, thiab ONT.
POL (Passive Optical LAN) Passive all-optical LAN
Hauv POL networking, kev sib txuas sib txuas hauv ib txwm siv LAN yog hloov los ntawm OLT (LM808E).Kab rov tav tooj liab yog hloov los ntawm fiber ntau optical;Cov keyboards nkag tau hloov los ntawm passive optical splitter.
ONT muab txheej 2 lossis txheej 3 ua haujlwm kom nkag mus rau cov neeg siv cov ntaub ntawv, lub suab, thiab cov kev pabcuam video los ntawm cov khoom siv xov tooj lossis wireless.
PON network downlink txais kev tshaj tawm hom: cov teeb liab kho qhov muag xa los ntawm OLT (LM808E) tau muab faib ua ntau lub teeb liab kho qhov muag nrog cov ntaub ntawv tib yam los ntawm kev sib cais ntawm qhov muag thiab xa mus rau txhua ONT; ONT xaiv tau txais nws cov pob ntawv raws li cov cim npe hauv pob ntawv thiab muab cov uas tsis sib haum tag.
Uplink kev taw qhia ntawm PON network: OLT (LM808E) faib lub sijhawm hla mus rau txhua ONT.ONT xa cov teeb liab nruj me ntsis raws li lub sijhawm no hlais thiab kaw qhov chaw nres nkoj kho qhov muag raws li lub sijhawm hlais uas tsis yog rau nws.Lub sij hawm uplink lub qhov rais teem sij hawm mechanism yog nyob ntawm ntau yam thev naus laus zis ntawm PON.
Kev nkag siab ntawm lub hauv paus ntsiab lus ntawm PON thev naus laus zis pab peb siv cov thev naus laus zis no ntau tshaj plaws hauv kev tsim hluav taws xob, tshwj xeeb tshaj yog cov yam ntxwv ntawm kev siv hluav taws xob (tsis muaj hluav taws xob) ntawm cov khoom siv kho qhov muag, thiab qhov sib txawv ntawm cov kev hloov pauv cov qauv tsim tshwj xeeb yuav tsum tau them sai sai rau .Los xyuas kom meej tias cov pob ntawv tsheb nyob rau hauv ob qho kev taw qhia yog xa mus rau ib qho tseem ceeb fiber ntau, PON txais yuav yoj-division hom.Tom qab txoj kev loj hlob mus rau 10 Gigabit PON, plaub ntu wavelength yog siv rau optical fiber multiplexing.
Optical ntiaj teb, Limee daws!Cia peb txuas ntxiv peb cov kev sib tham ntawm txhua lub ntiaj teb optical lwm zaus.
