ONU (Optical Network Unit) optical network unit, ONU muab faib ua active optical network unit thiab passive optical network unit.Feem ntau, cov cuab yeej nruab nrog kev saib xyuas lub network nrog rau cov khoom siv kho qhov muag, cov khoom siv hluav taws xob sab saud, thiab ntau lub tshuab hluav taws xob txuas txuas hu ua optical nodes.Lub PON siv ib qho fiber ntau optical txuas rau OLT, thiab tom qab ntawd OLT txuas rau ONU.ONU muab kev pabcuam xws li cov ntaub ntawv, IPTV (xws li kev sib tham sib tham hauv xov tooj cua), thiab lub suab (siv IAD, piv txwv li Integrated Access Device), tiag tiag paub txog "triple-play" daim ntawv thov.
Nta
Xaiv kom tau txais cov ntaub ntawv tshaj tawm xa los ntawm OLT;
Teb rau qhov sib txawv thiab lub zog tswj cov lus txib tawm los ntawm OLT;thiab ua kom raug hloov kho;
Cache tus neeg siv cov ntaub ntawv Ethernet thiab xa mus rau saum toj kawg nkaus hauv lub qhov rai xa xa los ntawm OLT;
Ua raws li IEEE 802.3/802.3ah;
· Tau txais rhiab heev li -25.5dBm;
· Xa lub zog mus txog -1 txog +4dBm;
PON siv ib qho fiber ntau optical txuas rau OLT, thiab tom qab ntawd OLT txuas rau ONU.ONU muab kev pabcuam xws li cov ntaub ntawv, IPTV (xws li kev sib tham sib tham hauv xov tooj cua), thiab lub suab (siv IAD, piv txwv li Integrated Access Device), paub txog "triple-play" daim ntawv thov;
· Tus nqi siab tshaj PON: symmetrical 10Gb / s cov ntaub ntawv nce thiab nqis qis, VoIP lub suab thiab IP kev pabcuam video;
· ONU "plug thiab ua si" raws li kev tshawb pom tsis siv neeg thiab teeb tsa;
· Cov kev pabcuam zoo tshaj plaws (QoS) ua haujlwm raws li kev pom zoo qib kev pabcuam (SLA) 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 lub teeb lub zog noj;
· Txhawb kev tuag Gasp muaj nuj nqi;
Kev faib tawm
Active lub teeb
Lub active optical network chav tsev feem ntau yog siv thaum peb tes hauj lwm sib koom ua ke, thiab nws integrates CATV full-band RF tso zis;zoo VOIP suab;peb-txheej routing hom, wireless nkag tau thiab lwm yam kev ua haujlwm, uas tuaj yeem yooj yim paub txog peb qhov kev sib txuas ua ke cov khoom siv davhlau ya nyob twg.
Passive teeb
Passive ONU (Optical Network Unit) yog ib qho khoom siv sab nraud ntawm GEPON (Gigabit Passive Optical Network), uas yog siv los txiav cov kev pabcuam xa los ntawm OLT (Optical Line Terminal) los ntawm EPON (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, VideoConference thiab lwm yam kev pab cuam.ONU, raws li tus neeg siv-sab ntaus ntawv rau FTTx daim ntaub ntawv, 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 kawg daws teeb meem rau cov neeg siv 'wired access, GEPON ONU yuav ua lub luag haujlwm tseem ceeb hauv kev tsim kho network tag nrho ntawm NGN (Next Generation Network) yav tom ntej.
UTStarcom ONU 1001i yog tus nqi siv nyiaj siv hluav taws xob siv hauv GEPON systems.Nws yog tsim los rau cov neeg siv hauv tsev thiab cov neeg siv SOHO, thiab muab kev sib txuas gigabit broadband rau cov neeg siv lub rooj vag thiab / lossis PCs.ONU 1001i muab ib qho 1000Base-TEthernet network chaw nres nkoj rau cov ntaub ntawv thiab IPTV cov kev pabcuam video.ONU1001i tuaj yeem raug teeb tsa thiab tswj hwm los ntawm UTStarcom BBS series kho qhov muag kab davhlau ya nyob twg (OLT).
daim ntawv thov
Lub sab sauv ntawm ONU 1001i txuas nrog lub hauv paus chaw ua haujlwm (CO) los ntawm GEPON chaw nres nkoj, thiab cov dej ntws qis yog rau cov neeg siv ib leeg lossis SOHO cov neeg siv los muab 1 Gigabit Ethernet network chaw nres nkoj.Raws li kev daws teeb meem yav tom ntej ntawm FTTx, ONU 1001i muab lub suab muaj zog, cov ntaub ntawv ceev ceev thiab cov kev pabcuam video los ntawm ib leeg-fiber GEPON.
