IINKCUKACHA ZEMVELISO

Ingcaciso yeMveliso

I-GWR3300 rack i-reck yendlela yokubuyisela i-receiver yenzelwe i-CATV yangaphakathi yokubuyisela umqondiso ukufumana.Kwi-rack ye-19 "1RU, kukho i-4 ephezulu ezimeleyo yokubuyisela i-receiver optical receivers, efumana indlela yokubuya ye-optical signals ukusuka kwi-nodes yethu ye-optical kwimeko ye-fiber kwisakhiwo okanye ezine-PON network xa kukho i-fiber ekhaya.Umamkeli ngamnye unekhowudi ye-PIN eyakhiweyo ephantsi, i-preamplifier ye-GaAs, isihluzo sokupasa ibhanti ephantsi kunye nenqanaba eliphezulu lemveliso yeamplifier yeRF, ebonelela ukuya kuthi ga kwi-45dBmV inqanaba lokuphuma kwiphaneli yangasemva ye-19” 1RU.I-PIN diode isekela i-1260nm ~ 1650nm ubude be-optical wavelength, kubandakanywa ne-1310nm eyaziwayo, i-1550nm kunye nezinye iziteshi ze-CWDM.Kwiphaneli yangaphambili, kukho izibuko lovavanyo le-RF enye -20dB kunye nesixhobo esinye esilungelelaniswayo esilungelelanisiweyo kumamkeli ngamnye, okwenza kube lula ukusetwa kwendlela nganye yokubuya inqanaba le-RF yokuphuma.I-bandwidth yomamkeli ngamnye wendlela yokubuya yi-5MHz ~ 204MHz, i-optical node ye-RF ehambelana nokwahlulahlula kwe-42/54MHz, 65/85MHz, 85/102MHz, 204/258MHz, exhasa i-Docsis 2.0, i-Docsis 3.0 kunye ne-Docsis 3.1 i-modem yentambo ye-RF inyuka.Ngamanye amazwi, i-GWR3300 inokujongana nayo yonke imiqondiso yeCATV ekhuphukayo, kungakhathaliseki ukuba i-optical nodes okanye i-micronodes ye-RFoG.

Ngaphandle kweendlela ezine ezizimeleyo zokubuya kwemveliso yeRF, kukho izibuko enye yeRF edibanisa iziphumo ezine zomamkeli njengemveliso enye yeRF, elungele uqhagamshelo lwezibuko lwase-US lweCMTS.

Ngokusebenza okuphezulu kwefotodiode kunye neamplifier ye-hybrid, i-GWR3300 ibonelela ngebhendi yendlela ecocekileyo yokubuyela kwiModem yeCable yokuhambisa imiqondiso.Isalathisi samandla okukhanya kunye nezibuko lovavanyo lwe-RF kwiphaneli yangaphambili inokubonisa ubume bomamkeli.
