GLB3500A-2R Twin Fiber Optic LNB

GLB3500A-2R satelite LHCP/RHCP FTTH Optical LNB o se fiber optic receiver fa'aliliuina fa'ailoga opitika i RF mo le sili atu ma le lua tali satelite. Galulue ma Greatway GLB3500A-2T satelite TV fiber optic transmitter, GLB3500A-2R outputs maualuga Terrestrial TV + LHCP ma Terrestrial TV + RHCP RF faailoilo i se aiga e sili atu nai lo le lua tali satelite. O lenei FTTH Twin LNB e mafai ona lua RF galuega, e mafai e RF port ta'itasi ona fesuia'i le LHCP po'o le RHCP fa'ailo fa'ailoga e ala ile 13V po'o le 18V DC mai le satelite.

masaniLNBoLoiNoiseBloka, liliu Ku Band 10.7GHz ~ 12.75GHz RF po C Band 3.7GHz ~ 4.2GHz RF i 950MHz ~ 2150MHz AFAI mo sat taliaina. 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

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 tekonolosi, opitika LNB e mafai ona i ai le galuega tutusa RF port lagolago DiSEqC.

GLB3500A-2R ei ai le 1310nm / 1490nm WDM filifiliga mo le galulue faʻatasi ma GPON / EPON ONU i soʻo se mataupu FTTH, lea e mafai ai ona faʻapipiʻi TV satelite i luga ole GPON / EPON network.
