GLB3500A-2R Twin Fiber Optic LNB

I-GLB3500A-2R isathelayithi LHCP/RHCP FTTH I-Optical LNB ngumamkeli wefiber optic oguqula umqondiso obonayo ube yiRF ngaphezu kwesibini sabamkeli besathelayithi. Ukusebenza neGreatway GLB3500A-2T yesathelayithi yeTV fiber optic transmitter, GLB3500A-2R ikhupha umgangatho ophezulu weTerrestrial TV+ LHCP kunye neTerrestrial TV + RHCP RF umqondiso kusapho olunye olunabamkeli besathelayithi abangaphezu kwesibini. Le FTTH Twin LNB inokuba neziphumo zeRF ezimbini, izibuko leRF ngalinye linokutshintsha i-LHCP okanye i-RHCP yesiginali yemveliso nge-13V okanye i-18V DC ngamandla asuka kumamkeli wesathelayithi.

RhoqoLNByiLowNoiseBtshixa, ukuguqula Ku Band 10.7GHz ~ 12.75GHz RF okanye C Band 3.7GHz~4.2GHz RF ukuya 950MHz~2150MHz IF for sat receiver. 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 inokuveliswa ukuya kuthi ga kwi-500K ye-LNB yamehlo

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-GLB3500A-2R ine-1310nm/1490nm inketho ye-WDM yokusebenzisana ne-GPON/EPON ONU kuyo nayiphi na imeko ye-FTTH, eyenza ukuba kufakwe i-TV yesathelayithi phezu kwe-GPON/EPON network.
