GLB3500A-2R ejima Fiber Optic LNB
Nkọwa ngwaahịa
GLB3500A-2R satịlaịtị LHCP/RHCP FTTH Optical LNB bụ eriri optic nnata na-atụgharị mgbama ngwa anya na RF maka ihe karịrị abụọ satịlaịtị nnata. Na-arụ ọrụ na Greatway GLB3500A-2T satịlaịtị TV fiber optic transmitter, GLB3500A-2R na-ewepụta akara ngosi Terrestrial TV + LHCP na Terrestrial TV + RHCP RF nye otu ezinụlọ nwere ihe karịrị ndị nnata satịlaịtị abụọ. Nke a FTTH Twin LNB nwere ike nweta ihe abụọ RF, ọdụ ụgbọ mmiri RF ọ bụla nwere ike ịgbanwe LHCP ma ọ bụ RHCP mmepụta site na ike 13V ma ọ bụ 18V DC sitere na satịlaịtị 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. N'ụlọ ọ bụla nwere eriri eriri, otu onye na-anata ngwa anya na-atụgharị eriri gaa na Sat Ọ BỤRỤ. Ntinye eriri na-atụgharị gaa na 950MHz ~ 2150MHz Ọ BỤRỤ na mmepụta maka sat nnata.
Satellite optical receiver na-arụ otu ọrụ dị ka LNB oge niile, ọ bụ LNB "mebere" n'ụlọ. Enwere ike ịkpọ ihe nnata anya satellite dị ka Optical LNB ma ọ bụ Fiber LNB.
A na-etinye LNB oge niile na efere chere ihu na mbara igwe. A na-etinye LNB anya n'ebe ọ bụla n'ụlọ ebe eriri dị. Enwere ike iwepụtaghachi ọdịnaya nke otu LNB oge niile ruo LNB ngwa anya 500K
LNB oge niile nwere polarities vetikal ma ọ bụ kehoraizin (13V/18V) yana band dị elu ma ọ bụ obere band (0Hz ma ọ bụ 22KHz). Site na teknụzụ CWDM/DWDM, anya LNB nwere ike inwe otu ọrụ RF ọdụ ụgbọ mmiri na-akwado DiSEqC.
GLB3500A-2R nwere 1310nm/1490nm WDM nhọrọ maka imekọ ihe na GPON/EPON ONU na ihe ọ bụla FTTH ikpe, nke na-enyere ịtinye satellite TV n'elu GPON/EPON netwọk.
