GFH2000-K TV ma Sat Fiber Optic LNB
Fa'amatalaga o oloa
GFH2000-K o le 45 ~ 2600MHz 1550nm fiber optic receiver ma WDM uafu i FTTH ONU. I le avea ai o se LNB fibre optic, GFH2000-K o loʻo i ai le laina lautele o le LNB (300MHz ~ 2350MHz) poʻo le LNB masani (950MHz ~ 2150MHz) + CATV RF fusi, e galue i le GWT3500S (CATV + Sat) fiber optic transmitter poʻo GLB3500MT-D (Terr TV + Sat IF) fibre optic transmitter po'o le broadband optical transmitter.
LNB masani o le Low Pisa Block, liliu Ku Band 10.7GHz ~ 12.75GHz RF po C Band 3.7GHz ~ 4.2GHz RF i 950MHz ~ 2150MHz AFAI mo sat receiver. I le SMATV i luga o le fiber system, e tasi le transmitter liliu LNB IF i fiber. A maeʻa le fiber optic amplifier ma le PON, e tufatufaina atu faʻailoga mata i le selau poʻo le afe o aiga FTTH. I fale ta'itasi e iai uaea fibre, e tasi le mea fa'apipi'i e fa'aliliuina alava i le Sat IF. O le fa'aoga alava e liliu i le 950MHz~2150MHz pe'ā fa'aulufale mo le fa'anofonofo.
Satelite opitika e maua le matafaioi tutusa ma le LNB masani, o se "virtual" LNB i le fale. E mafai ona ta'ua le fa'auivi fa'apitoa satelite o le Optical LNB po'o le Fiber LNB.
E fa'apipi'i LNB masani i ipu fa'asaga i le lagi. O lo'o fa'apipi'i le Optical LNB i so'o se mea ile fale e maua ai le fiber. O mea o lo'o i totonu o le LNB masani e tasi e mafai ona toe gaosia e o'o atu i le 500K opitika LNBs.
I le avea ai o se LNB mataʻutia lautele, GFH2000-K e mafai ona galue ma soʻo se vaega lona tolu GPON ONU poʻo 1270nm / 1577nm XGPON ONU poʻo 1524 ~ 1544 / 1596 ~ 1599nm NGPON2 ONU, faʻaofiina le tele o faʻasalalauga maualuga CATV + SAT vitio i le faʻaaogaina o soʻo se initaneti e aunoa ma le faʻaaogaina bandwidth.
isi vaega:
•High Linearity Photodiode mo Terrestrial TV ma Satellite TV RF.
•45MHz~2600MHz (lalo) RF Fa'aulu.
•1270nm/1577nm Optical Bypass taulaga i XGPON ONU filifiliga.
•1524 ~ 1544nm / 1596 ~ 1599nm ala pasi i le NGPON2 ONU filifiliga.
•DC Malosiaga ma fa'ailoga mata'itusi fa'apipi'i LED.
•Tuto'atasi 10 ~ 18V DC pusa mana fetuutuunai.
