GLB3500M-3 Terr TV na Otu wideband LNB n'elu eriri
Nkọwa ngwaahịa
GLB3500M-3 bụ a modular CWDM brọdband RF eriri njikọ, na-ebunye abụọ 290MHz ~ 2350MHz Satellite RF (na-akwado UK 290MHz ~ 2340MHz ma ọ bụ Europe 300MHz ~ 2350MHz) na otu 45MHz ~ 806MHz Terrestrial TV RF multi ndị debanyere aha otu SM. RF wideband dị na 1530nm ma ọ bụ 1550nm, terrestrial TV RF dị na 1570nm. Enwere fiber optic CWDM mux ma ọ bụ ngwaọrụ demux na transmitter anya ma ọ bụ nata iji ghọta otu nnyefe eriri.
SMTV (Satellite Master Antenna TV) bụ ihe ama ama inye ndị debanyere aha bi n'ụlọ ma ọ bụ obodo TV satịlaịtị na TV terrestrial. SMTV omenala nwere ike kesaa ọdịnaya antenna ukwu site na multiswitch na ndị na-anata satịlaịtị n'elu eriri coaxial. N'ihi ọnwụ dị elu na ugboro satịlaịtị dị elu, anya USB SMTV bụ ihe na-erughị mita 150 ọbụlagodi na ọ bụrụ na ọ na-eme ihe n'ịntanetị. N'adịghị ka usoro Quattro LNB SMTV oge niile, sistemụ LNB SMTV wideband nwere njikọ njikọ RF ọkara na ọnụọgụ eriri ọkara, nke na-echekwa ọnụ ahịa nnyefe. Mgbe eriri gachara n'ụlọ ahụ, wideband SMTV optical receiver ga-arụ ọrụ na dCSS multiswitch iji nweta otu mmepụta RF nwere eriri 32 ike, ebe eriri onye ọ bụla maka onye debanyere aha satịlaịtị STB enweghị ike. Nke a otu eriri na ụlọ na otu coaxial cable ka multi ọrụ na ụlọ na-eme ka eriri echichi na mmezi mfe.
GLB3500M-3 eriri njikọ gụnyere GLB3500M-3T ngwa anya transmitter na GLB3500M-3R ngwa nnata. Na CWDM lasers/photodiode na obere mkpọtụ RF nweta akara sekit, otu GLB3500M-3T nwere ike nyefee RF dị elu na kacha 32pcs GLB3500M-3R optic receivers ozugbo.
