IINKCUKACHA ZEMVELISO

Ingcaciso yeMveliso

I-TV yesathelayithi ye-GLB3500E-2R FTTH i-Optical LNB yifiber optic receiver eguqula umqondiso obonayo ube yiRF ukuya kuthi ga kwi-4 yesathelayithi yabamkeli kwikhaya elinye.Ukusebenza kunye ne-Greatway GLB3500E-2T ye-satellite TV optical transmitter, i-GLB3500E-2R inemodyuli ye-SatCR eyakhelwe ngaphakathi ejongene ne-wideband satellite RF, ikhupha iibhendi ezi-4 zomsebenzisi wesathelayithi kwizibuko elinye le-SatCR RF kwi-4 unicable satellite receivers.

I-LNB yesiqhelo yiBhlokhi yeNgxoxo ePhantsi, iguqula i-Ku Band 10.7GHz~12.75GHz RF okanye i-C Band 3.7GHz~4.2GHz RF ukuya ku-950MHz~2150MHz IF kumamkeli ahlala.Kwi-SMATV ngaphezulu kwenkqubo yefayibha, isidluliseli esinye siguqula i-LNB IF kwifayibha.Emva kwe-fiber optic amplifier kunye ne-PON, isignali ye-optic isasazwa kumakhulu okanye amawaka eentsapho ze-FTTH.Kwikhaya ngalinye elinefayibha intambo, enye i-optical receiver iguqula ifayibha ibe yiSat IF.Igalelo leFayibha lijikela kwi-950MHz ~ 2150MHz IF imveliso yesat receiver.

Isathelayithi i-optical receiver idlala indima efanayo ne-LNB eqhelekileyo, yi-LNB "ebonakalayo" ekhaya.Isathelayithi i-optical receiver inokubizwa ngokuba yi-Optical LNB okanye iFiber LNB.

I-LNB eqhelekileyo ifakwa kwisitya esijonge esibhakabhakeni.I-Optical LNB ifakwe naphi na ekhaya apho ifayibha ifumaneka khona.Imixholo ye-LNB enye eqhelekileyo inokuphinda iveliswe ukuya kuthi ga kwi-500K yee-LNB zamehlo.

I-LNB yesiqhelo ineepolarities ezithe nkqo okanye ezithe tye (13V/18V) kunye nebhendi ephezulu okanye ibhendi esezantsi (0Hz okanye 22KHz).Ngeteknoloji yeCWDM/DWDM, i-LNB yamehlo inokuba nomsebenzi ofanayo wezibuko le-RF elixhasa iDiSEqC.

I-GLB3500E-2R ine-1310nm/1490nm/1550nm izibuko le-WDM lokukhetha ukusebenzisana ne-GPON ONU kuso nasiphi na isicelo se-FTTH, esenza ukuba imixholo yesathelayithi ye-Quattro LNB ifakwe kwinkqubo ye-GPON.
