GLB3500M-4D Ma Satellite Anayi DWDM FTTH okhala ndi GPON
Mafotokozedwe Akatundu
GLB3500M-4D ndi ulalo wa DWDM burodibandi RF fiber, kutumiza ma 950 ~ 2150MHz Satellite RF ndi 174 ~ 806MHz Terrestrial TV RF pa SM fiber imodzi kwa olembetsa ambiri a FTTH. Ma satellite RF anayi amatha kukhala VL/VH/HL/HH kuchokera ku Quattro LNB imodzi kapena ma 32UB okhazikika anayi kuchokera ku ma satellite dCSS LNB anayi.
Ma satellites anayi ali ndi ma transponder ambiri pa satellite iliyonse. M'malo mwake, 20% yokha zomwe zili mu satelayiti ndizodziwika mwa olembetsa 80%. Zonse zomwe zili mkati kuchokera ku ma satellites anayi pamwamba pa chingwe cha coaxial kupita ku chingwe cha fiber kunyumba iliyonse ndizokwera mtengo. GLB3500M-4D dongosolo amasankha transponder otchuka kwambiri kwa onse olembetsa. Ma transponder 32 kuchokera pa satellite iliyonse ayenera kukhala ndi zomwe zili mu satelayiti. Ndi ukadaulo wa 4ch DWDM komanso mphamvu yayikulu ya 1550nm Optical amplifier, GLB3500-4D imatha kuyika ma satelayiti 4 okhala ndi ma transponder 128 okwana munjira iliyonse ya GPON kapena XGPON. Pa dCSS LNB static mode, olandila satelayiti amatha kukhala mawonekedwe okhazikika omwe amawonera zonse 4 zosankhidwa ndi satellite.
Ulalo wa fiber wa GLB3500M-4D umaphatikizapo GLB3500M-4TD DWDM optical transmitter ndi GLB3500M-4RD4 FTTH Optical receiver. Wolandila kuwala ali ndi madoko 4 a RF, doko lililonse limathandizira kuwonera 32UB yomwe ikubwera ya satellite iliyonse yomwe ikubwera. Ndi ma DWDM lasers/photodiode komanso phokoso lotsika la RF lowongolera, GLB3500M-4TD imodzi imatha kupereka RF yapamwamba kwambiri mpaka 32 GLB3500M-4RD4 optic receiver mwachindunji kapena zikwizikwi za GLB3500M-4RD4 optic olandila kudzera pamagetsi apamwamba kwambiri opangira amplifier.
