IINKCUKACHA ZEMVELISO

Ingcaciso yeMveliso

I-GWR1200 i-Optical Node ine-outdoor die-cast aluminium yezindlu ephuma phambili kwi-analog ye-TV ye-analog, i-DVB-C kunye ne-CMTS DS imiqondiso kunye nokuthumela imiqondiso yemodem yentambo enyukayo kwimodi eqhelekileyo okanye eqhumayo ngaphezu kwefayibha enye ye-Bi-directional okanye i-2nd fiber. Zilungele ifayibha ehambele phambili kwindawo (FTTP) kunye nefiber kwisakhiwo (FTTB) izicelo kwi-CATV kunye neenethiwekhi ze-intanethi. Indawo ye-GWR1200 ibonelela ngemveliso ephezulu yeRF ukuya kuthi ga kwi-1.2 GHz (1218MHz) eya kunciphisa okanye iphelise imfuneko yeamplifier ye-post-node kuthungelwano.

I-GWR1200 node ilungele izicelo zokuxinana okuphezulu: i-MDU, iiyunivesithi, izibhedlele kunye neepaki zoshishino. I-GWR1200 izidla nge-50dBmV ephumayo elawula nakuphi na ukusekwa kobungakanani. Isidlulisi sendlela yokubuya inokuba yi-1310nm okanye i-1550nm ngokuxhomekeke kwiimfuno zenkqubo. Itekhnoloji ye-WDM yokuzikhethela ivumela ukusebenza ngeendlela ezimbini kwifiber enye. Abathumeli be-CWDM banikezelwa ukuba badibanise iindlela ezininzi zeendlela ezimbini kwifayibha enye.

Njengendawo yokukhanya yangaphandle, i-GWR1200 iyile ukhuselo lwe-4KV kuwo onke amazibuko eRF.
I-GWR1200 yokuhambisa indlela yokubuyisela inokusetwa kwimowudi yokugqabhuka ukunciphisa ingxolo yendlela yokubuya. Isixhobo sisebenzisa i-fiber enye kwaye sifumana izibonakaliso ezisezantsi kwi-1550nm kunye nee-transmitters ezibuyayo zinokuodolwa njenge-1310nm okanye i-1610nm okanye i-CWDM wavelengthes ngokuxhomekeke kwiimfuno zenkqubo. Njengesixhobo se-RFOG iyahambelana ne-DOCSIS® kunye nayo yonke imisebenzi ye-ofisi esemva ye-HFC.
