IINKCUKACHA ZEMVELISO

Ingcaciso yeMveliso

I-GFH2000-K yi-45~2600MHz 1550nm umamkeli wefiber optic enezibuko le-WDM ukuya kwi-FTTH ONU. Njengesiseko se-fiber optic LNB, i-GFH2000-K ine-wideband ye-LNB (300MHz ~2350MHz) okanye i-LNB eqhelekileyo (950MHz~2150MHz)+CATV RF iibhendi, isebenza ne-GWT3500S (CATV+Sat) isidluliseli sefayibha optic okanye GLB3500MT TV+-D Sat IF) i-fiber optic transmitter okanye i-wideband optical transmitter.

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.

Njenge-LNB ye-Optical jikelele, i-GFH2000-K inokusebenza nalo naliphi na iqela lesithathu i-GPON ONU okanye i-1270nm/1577nm XGPON ONU okanye 1524~1544/1596~1599nm NGPON2 ONU, ifakela usasazo olukhulu lomgangatho ophezulu we-CAFTTH+SAT ubhalisele iividiyo ze-intanethi bandwidth.
