GLB3500M-6 Wideband isii RF n'elu eriri
Nkọwa ngwaahịa
GLB3500M-6 bụ modular 6ch CWDM Satellite RF njikọ eriri, na-ebufe 6ch wideband 174MHz ~ 2350MHz RF n'elu otu SM fiber na otu ma ọ bụ multi optical receiver. Ogologo ikuku anya nke CWDM ọ bụla na-ebu otu 174 ~ 2350MHz RF, na-akwado Terrestrial TV 174 ~ 806MHz ma ọ bụ 950 ~ 2150MHz ma ọ bụ ngwakọta nke Terr TV na Sat RF, na-eme ka akara ngosi RF dị mma na ikewapụ n'etiti akara RF.
Emebere GLB3500M-6 tumadi maka ngwa abụọ: ọtụtụ antenna satịlaịtị na isi TV na SMTV.
E jiri ya tụnyere satịlaịtị RF n'elu coaxial cable na TV Headend, GLB3500M-6 nwere uru atọ: 1. Kachasị 6 satịlaịtị antenna RFs n'elu otu SM eriri na Headend ụlọ ọrụ na nnọọ ogologo anya site 100 mita ka 10Km; 2. Nchekwa ọkụ na Headead equipments n'ihi na-abụghị conductive eriri eriri; 3. Grounding kewapụrụ n'etiti Satellite efere ebe na Headend akụrụngwa ọnọdụ.
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 mfu dị elu na satịlaịtị dị elu Ọ BỤRỤ na ya, anya USB SMTV na-erughị mita 150 ọbụlagodi na ọ bụrụ na ọ na-eme ihe n'ịntanetị. GLB3500M-6 na-enyere SMTV aka karịa fiber ka ọ nwetakwu ụlọ na ndị debanyere aha na 5Km radius fiber distance. Yana PLC fiber splitter na cascading multiswitchs na ụlọ ọ bụla, GLB3500M-6 nwere ike ikesa multi satellite antenna RFs na Terr TV na ọnụ ọgụgụ nke ndị debanyere aha na obodo.
GLB3500M-6 eriri njikọ gụnyere GLB3500M-6T ngwa anya transmitter na GLB3500M-6R ngwa nnata. Na CWDM lasers/photodiode na obere mkpọtụ RF inweta akara sekit, otu GLB3500M-6T nwere ike na-ebuga RF dị elu na kacha 32 GLB3500M-6R optical receivers.
