GFH2000-K bụ 45 ~ 2600MHz 1550nm eriri optic nnata na WDM n'ọdụ ụgbọ mmiri na FTTH ONU. Dị ka a isi fiber optic LNB, GFH2000-K nwere wideband LNB (300MHz ~ 2350MHz) ma ọ bụ mgbe LNB (950MHz ~ 2150MHz) + CATV RF bands, ọ na-arụ ọrụ na GWT3500S (CATV + Sat) fiber optic transmitter ma ọ bụ GLB3500r TV-D ( Sat IF) eriri optic transmitter ma ọ bụ wideband ngwa anya transmitter.

Mgbe niile LNB bụ Low Noise Block, na-atụgharị Ku Band 10.7GHz ~ 12.75GHz RF ma ọ bụ C Band 3.7GHz~4.2GHz RF ka 950MHz ~ 2150MHz Ọ BỤRỤ na maka nọdụ nnata. Na SMTV n'elu sistemu eriri, otu onye na-ebugharị na-atụgharị LNB Ọ BỤRỤ na eriri. Mgbe eriri optic amplifier na PON gasịrị, a na-ekesa mgbaàmà optic na narị otu narị ma ọ bụ puku kwuru puku ezinụlọ FTTH.
