ONU ua haujlwm li cas

ONU muab faib ua active optical network unit thiab passive optical network unit.
Feem ntau, cov khoom nruab nrog optical receivers, uplink optical transmitters, thiab ntau tus choj amplifiers rau kev saib xyuas network yog hu ua optical node.

ONU ua haujlwm
1. Xaiv kom tau txais cov ntaub ntawv tshaj tawm xa los ntawm OLT;
2. Teb rau cov lus txib thiab tswj fais fab uas muab los ntawm OLT;thiab ua kom raug hloov kho;
3. Tsis pub tus neeg siv cov ntaub ntawv Ethernet thiab xa mus rau hauv cov kev taw qhia saum toj kawg nkaus hauv qhov xa qhov rai faib los ntawm OLT.
Ua raws li IEEE 802.3 / 802.3ah
Tau txais rhiab heev txog -25.5dBm
Fais fab mus txog -1 txog +4dBm
Ib qho kev kho qhov muag fiber ntau muab kev pabcuam xws li cov ntaub ntawv, IPTV, thiab lub suab, thiab ua tiav cov ntawv thov "triple-play".
· Tus nqi siab tshaj PON: uplink thiab downlink symmetrical 1Gb/s cov ntaub ntawv, VoIP suab thiab IP video kev pab cuam.tus
ONU "plug thiab ua si" raws li kev tshawb pom tsis siv neeg thiab teeb tsa
Advanced Quality of Service (QoS) nta raws li Service Level Agreement (SLA) sau nqi
Kev tswj chaw taws teeb muaj peev xwm txhawb nqa los ntawm kev nplua nuj thiab muaj zog OAM ua haujlwm
High rhiab heev lub teeb tau txais thiab tsawg input teeb lub zog noj
Txhawb Dying Gasp muaj nuj nqi
Active optical network unit
Lub active optical network chav tsev feem ntau yog siv nyob rau hauv kev koom ua ke ntawm peb tes hauj lwm.Nws integrates CATV full-band RF tso zis;zoo VOIP suab;peb-txheej routing hom, wireless nkag tau thiab lwm yam kev ua haujlwm, thiab yooj yim paub txog cov khoom siv davhlau ya nyob twg nkag ntawm triple network kev koom ua ke.
Passive Optical Network Unit
Lub passive optical network unit yog tus neeg siv-sab ntaus ntawv ntawm GPON (Gigabit Passive Optical Network) system, thiab yog siv los txiav cov kev pabcuam xa los ntawm OLT (Optical Line Terminal) los ntawm PON (Passive Optical Network).Kev koom tes nrog OLT, ONU tuaj yeem muab ntau yam kev pabcuam dav dav rau cov neeg siv sib txuas.Xws li Internet surfing, VoIP, HDTV, Video Conference thiab lwm yam kev pab cuam.Raws li tus neeg siv-sab ntaus ntawv ntawm FTTx daim ntawv thov, ONU yog ib tug high-bandwidth thiab nqi-zoo davhlau ya nyob twg cov khoom tsim nyog rau kev hloov ntawm "tooj liab cable era" mus rau "optical fiber era".Raws li qhov kev daws teeb meem zoo tshaj plaws rau cov neeg siv kev siv xov tooj, GPON ONU yuav ua lub luag haujlwm txiav txim siab hauv kev tsim kho network tag nrho ntawm NGN (Next Generation Network) yav tom ntej.
HG911 ONU yog cov cuab yeej siv hluav taws xob zoo siv rau xPON system.Nws yog tsim los rau cov neeg siv hauv tsev thiab cov neeg siv SOHO, muab gigabit-speed broadband sib txuas rau cov neeg siv lub rooj vag thiab / lossis PCs.ONU muab ib qho 1000Base-T Ethernet chaw nres nkoj rau cov ntaub ntawv thiab IPTV cov kev pabcuam video.Nws tuaj yeem raug teeb tsa thiab tswj hwm los ntawm HUANET series kho qhov muag kab davhlau ya nyob twg (OLT).
Daim ntawv thov
ONU cov dej ntws txuas mus rau lub chaw ua haujlwm hauv nruab nrab (CO) los ntawm xPON chaw nres nkoj, thiab tus cwj pwm qis qis muab Gigabit Ethernet chaw nres nkoj rau ib tus neeg siv lossis SOHO cov neeg siv.Raws li kev daws teeb meem yav tom ntej rau FTTx, ONU 1001i muab lub suab muaj zog, cov ntaub ntawv ceev ceev thiab cov kev pabcuam video los ntawm ib leeg fiber ntau GEPON.
