GFH2000-K TV ati Sat Fiber Optic LNB
ọja Apejuwe
GFH2000-K jẹ 45 ~ 2600MHz 1550nm fiber optic olugba pẹlu ibudo WDM si FTTH ONU. Gẹgẹbi LNB fiber optic ipilẹ, GFH2000-K ni LNB wideband (300MHz ~ 2350MHz) tabi LNB deede (950MHz ~ 2150MHz) + awọn ẹgbẹ RF CATV, o ṣiṣẹ pẹlu GWT3500S (CATV + Sat) transmitter fiber optic tabi GLB3500r TV-D (T) Sat IF) Atagba opiti okun tabi atagba opiti jakejado.
Deede LNB jẹ Low Noise Block, iyipada Ku Band 10.7GHz ~ 12.75GHz RF tabi C Band 3.7GHz~4.2GHz RF to 950MHz ~ 2150MHz IF fun sat olugba. Ni SMTV lori eto okun, atagba kan yipada LNB IF si okun. Lẹhin ampilifaya fiber optic ati PON, ifihan agbara opitiki ti pin si awọn ọgọọgọrun tabi ẹgbẹẹgbẹrun awọn idile FTTH. Ni ile kọọkan pẹlu okun okun, ọkan opitika olugba iyipada okun to Sat IF. Iṣagbewọle Fiber yipada si 950MHz ~ 2150MHz IF iṣẹjade fun olugba sat.
Satẹlaiti opitika olugba yoo kanna ipa bi deede LNB, o jẹ a "foju" LNB ni ile. Satẹlaiti opitika olugba le ti wa ni a npe ni Optical LNB tabi Fiber LNB.
LNB deede ti fi sori ẹrọ ni satelaiti ti nkọju si ọrun. Opitika LNB ti fi sori ẹrọ nibikibi ni ile nibiti okun wa. Awọn akoonu ti LNB deede kan le tun ṣejade to awọn LNB opitika 500K.
Gẹgẹbi LNB opitika gbogbo agbaye, GFH2000-K le ṣiṣẹ pẹlu ẹnikẹta GPON ONU tabi 1270nm/1577nm XGPON ONU tabi 1524 ~ 1544/1596 ~ 1599nm NGPON2 ONU, fifi sii awọn fidio didara giga ti o ga julọ CATV+SAT laisi awọn fidio si FTTH eyikeyi ayelujara. bandiwidi.
Awọn ẹya miiran:
•Photodiode Linearity giga fun TV Terrestrial ati Satẹlaiti TV RF.
•45MHz ~ 2600MHz (isalẹ) RF Ijade.
•1270nm/1577nm Optical Bypass ibudo si aṣayan XGPON ONU.
