Luv Views JHA700-701GAW-HR220 yog fiber ntau rau hauv tsev ntau qhov kev pabcuam nkag GPON ONU. Nws yog raws li kev paub tab, ruaj khov, tus nqi siab GPON thev naus laus zis thiab muaj gigabit Ethernet hloov, WDM thiab HFC thev naus laus zis. JHA700-701GAW-HR220 muaj ntau dua bandwidth, muaj kev ntseeg siab dua, kev tswj tau yooj yim thiab kev pabcuam zoo (QoS) lav nrog kev ua haujlwm ntawm cov cuab yeej ua tau raws li ITU-T G. 984 cov kev cai thiab muaj kev sib raug zoo nrog peb cov tuam txhab OLT. GPON yog cov tiam tshiab ntawm kev nkag tau network technology. ITU-T G.984 yog tus qauv raws tu qauv ntawm GPON. Tus qauv GPON txawv ntawm lwm cov qauv PON uas nws ua tiav cov bandwidth siab dua thiab ua haujlwm zoo dua siv cov pob ntawv loj, sib txawv-ntev ntev. GPON muaj kev ntim khoom zoo ntawm cov neeg siv tsheb khiav, nrog cov kab segmentation tso cai rau kev pabcuam zoo dua (QOS) rau kev ncua sijhawm-rhiab suab thiab kev sib txuas lus video. GPON network muab kev ntseeg siab thiab kev ua tau zoo uas xav tau rau kev pabcuam kev lag luam thiab muab txoj hauv kev txaus nyiam kom xa cov kev pabcuam hauv tsev. GPON ua kom muaj fiber ntau rau hauv tsev (FTTH) kev xa tawm kev lag luam uas ua rau kev loj hlob sai thoob ntiaj teb. Nws txais ib qho fiber ntau WDM tshuab nrog downlink wavelength 1550nm thiab 1490nm, uplink wavelength 1310nm. Nws tsuas yog xav tau ib-core fiber ntau los xa cov ntaub ntawv thiab CATV kev pabcuam. JHA700-701GAW-HR220 tuaj yeem sib koom ua ke wireless ua haujlwm nrog ua tau raws li 802.11 n / b / g cov qauv kev, Nws tau tsim-hauv siab nce kev coj tus kav hlau txais xov, lub wireless kis tau tus nqi mus txog 300Mbps. Nws muaj cov yam ntxwv ntawm kev muaj zog nkag mus rau lub zog thiab kev pabcuam dav. Nws tuaj yeem muab cov neeg siv nrog cov ntaub ntawv sib kis tau zoo dua.
