GLB3500MT Terr TV na Sat Fiber Optic Transmitter
Nkọwa ngwaahịa
GLB3500M bụ 45 ~ 2600MHz RF modular n'elu njikọ eriri, na-ebufe ọwa TV Terrestrial na otu L-Band RF karịa otu eriri.
Satellite mgbasa ozi Direct (DBS) na Direct to Home (DTH) bụ ụzọ kacha ewu ewu maka ịnụ ụtọ TV satịlaịtị n'ụwa niile. Iji mee ya, antenna satịlaịtị, eriri coaxial, splitter ma ọ bụ multi-switcher na satịlaịtị nnata dị mkpa. Agbanyeghị, nrụnye antenna satịlaịtị nwere ike isiri ndị debanyere aha bi n'ụlọ ahụ ike. SMTV (satellite mater antenna TV) bụ ihe ngwọta dị mma maka ndị bi n'ụlọ ma ọ bụ obodo ịkọrọ otu efere satịlaịtị na terrestrial TV antenna. Site na eriri eriri, enwere ike ibunye akara SMTV RF na 30Km dị anya ma ọ bụ kesaa ya na ụlọ 32 ozugbo, na ụlọ 320 ma ọ bụ 3200 ma ọ bụ 32000 site na GWA3530 fiber optic amplifier.
GLB3500M nwere GLB3500MT transmitter modul na GLB3500MR modul nnata. GLB3500MT modul transmitter nwere otu ma ọ bụ abụọ ọdụ ụgbọ mmiri ntinye RF ebe GLB3500MR nwere otu ọdụ ụgbọ mmiri mmepụta RF. Na elu linearity 1550nm uncooled DFB laser, photodiode na obere mkpọtụ RF nweta akara sekit, GLB3500MT nwere ike na-ebuga elu àgwà TV ọwa na satịlaịtị RF n'elu eriri na ole na ole ndị debanyere aha ozugbo ma ọ bụ puku kwuru puku ndị debanyere aha FTTH site EDFA. Na 1310nm/1490nm/1550nm WDM nhọrọ, GLB3500M nwere ike itinye L-Band+TV RF n'elu GPON/GEPON. N'akụkụ ụdị modular, GLB3500M nwere ike ịnwe ụdị 19"1RU mgbe achọrọ ya. Ihe eriri na ụdị ụlọ rọba nke GLB3500MR bụ GFH2000 optical LNB, ebe ndị debanyere aha FTTH chọrọ naanị otu eriri ma wepụta akara satịlaịtị n'ọtụtụ ọnụ ụlọ n'ime ezinụlọ.
Atụmatụ ndị ọzọ:
• Ụlọ ihe nkedo aluminom kọmpat.
• Ntinye RF otu jikọtara ya na bandwit: 45 ~ 2600MHz ma ọ bụ.
• Ntinye RF abụọ kewapụrụ, gụnyere:
-Otu ntinye TV Terrestrial, bandwit: 174 -806 MHz.
-Otu ntinye LNB RF, bandwit: 950MHz ~ 2150MHz (13V ma ọ bụ 18V DC nhọrọ maka LNB na-arịọ).
• Otu ọdụ ụgbọ mmiri mmepụta RF.
• High Linearity 1550nm DFB Laser na Photodiode adịghị mma.
• Obere mkpọtụ sekit njikwa RF Gain.
