AON yog dab tsi?
Aon yog lub khoos phis tawm kho qhov muag, uas tsuas yog nruab rau kev sib kis-rau-point (PTP) network architecture. Txhua tus neeg siv tuaj yeem muaj cov kab hluav taws xob fiber ntau tshwj xeeb. Active optical network txhais tau hais tias nyob rau hauv cov txheej txheem ntawm cov teeb liab xa mus, hloov khoom siv xws li cov routers thiab hloov pob hluav taws xob, cov khoom siv hluav taws xob nquag, thiab lwm yam tau xa los ntawm cov khoom siv hauv chaw ua haujlwm mus rau tus neeg siv khoom faib. Cov khoom siv hloov hluav taws xob no yog tsav los ntawm lub zog hluav taws xob los tswj cov teeb liab faib thiab kev taw qhia cov cim ntawm cov neeg yuav khoom tshwj xeeb. Lub tshuab ua kom zoo dua cov khoom siv xws li lub teeb ci (laser), lub ntsuas pa, optical transceiver module, optical amplifier (fiber amplifier thiab semiconductor optical amplifier), thiab lwm yam.
PON yog dab tsi?
PON yog qhov sib txig sib txuas ntawm cov khoos phis tawm, cov lus taw qhia-ntau ntau lub network, uas yog lub thev naus laus zis tseem ceeb kom paub FTTB / FTTH. Hauv cov khoos phis tawm dhau los, ODN (cov xaib hluav taws xob sib faib network) tsuas yog siv cov kho qhov muag thiab cov khoom siv sib txig, thiab tsuas yog xav siv cov khoom siv nyob ntawm cov cim taw qhia thiab cov teeb liab tau txais qhov kawg. Hauv cov phiaj xwm PON li niaj zaus, cov kho qhov muag tawg yog qhov tseem ceeb, uas yog siv los cais thiab sau cov cim kho qhov muag kis tau sib txuas hauv lub network. Cov splitters rau PON no yog bidirectional. Nyob rau hauv cov kev taw qhia lawm, IP cov ntaub ntawv, lub suab, video thiab lwm yam kev pabcuam tau muab faib rau txhua ONU chav nyob ntawm PON los ntawm OLT hauv lub hauv paus chaw haujlwm los ntawm 1: n passive optical splitter hauv ODN, thiab nyob rau hauv cov kev taw qhia, ntau cov kev pabcuam cov ntaub ntawv los ntawm ib qho ONU txuas mus txuas ntxiv rau ib tus dhau los ntawm 1: n passive optical combiner hauv ODN tsis muaj kev cuam tshuam cov fiber ntau qhov kawg tau xa mus rau OLT tus txais ntawm lub zos kawg.
Lub tshuab hluav taws xob (passive optical network) suav nrog qhov kho qhov muag kab (OLT) tau nruab rau hauv nruab nrab tswj chaw nres tsheb thiab cov kab sib txuas ntawm cov sib txuas lus sib txuas network (onus) tau nruab rau hauv tus neeg siv' s site. Lub chaw xa khoom hluav taws xob (ODN) ntawm OLT thiab ONU suav nrog optical fiber thiab passive splitter lossis coupler.
Hauv AON network, cov neeg siv muaj cov kab fiber ntau tshwj xeeb, uas yooj yim los tswj, nthuav thiab txhim kho lub network. Thiab AON network npog dav dav, nthuav dav txog 100 kilometers; PON network feem ntau txwv rau 20 kis las ntawm optical fiber cable. Aon feem ntau qhia cov cim kho qhov muag los ntawm cov cuab yeej siv tau, thiab PON siv cov twj siv tsis muaj lub zog tsis muaj lub zog, uas ua rau ntau tus nqi ntawm AON network xa ntau dua li PON.
HTF yog cov kws tshaj lij OEM / ODM cov chaw tsim hluav taws xob ua kom dhau los ntawm kev sib txuas lus kho qhov muag, tsom rau kev muab cov qhua tuaj yeem nrog nres nres ib qho khoom tsim ntawm kev tsim, kev txhim kho thiab tsim cov khoom lag luam sib txuas lus.
