GLB2000A satelite TV FTTH opitika LNB fa'aliliuina fa'ailoga fa'apitoa i lua polarities RF mo le tasi satelite tali. Galulue fa'atasi ma Greatway GLB3500A-2T satelite TV fiber optic transmitter, GLB2000A fa'aulufalega maualuga Tele Terrestrial TV + Vertical/Horizontal RF faailoilo. E mafai e lenei ftth LNB ona fesuia'i le Vertical (po'o le RHCP) po'o le Fa'afa'alafaga (po'o le LHCP) fa'ailo fa'aulu mai le eletise 13V po'o le 18V DC mai le satelite.

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 fa'atino le matafaioi e pei o le LNB masani, o le "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.
• 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
• LNB masani o lo'o i ai polarity tu'usa'o po'o fa'alava (13V/18V) ma fa'aili maualuga po'o le fa'alili maualalo (0Hz po'o le 22KHz). E ala i le CWDM/DWDM tekinolosi, opitika LNB e mafai ona i ai le galuega tutusa RF port mai le tasi SM fiber.

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.

LNB masani o lo'o i ai polarity tu'usa'o po'o fa'alava (13V/18V) ma fa'aili maualuga po'o lalo ifo (0Hz po'o 22KHz). E ala i le CWDM/DWDM tekinolosi, opitika LNB e mafai ona i ai le galuega tutusa RF port mai le tasi SM fiber.

GLB2000A o loʻo i ai le 1310nm / 1490nm WDM filifiliga mo le galulue faʻatasi ma GPON / EPON ONU i soʻo se mataupu FTTH, lea e mafai ai ona tuʻuina DTT + SAT i luga ole GPON / EPON fesoʻotaʻiga.
